+
+ * Makefile: Removed etex.tex.
+ * etex.tex: Removed.
+
+ * xeplain.tex: Improved hyperlink messages.
+
+ * doc/Makefile: Use texi2dvi --pdf instead of texi2pdf.
+
+ * xeplain.tex (beginpackages): Save and restore \input to avoid
+ redefinition by miniltx.tex and packages (\packageinput stores the
+ redefinition).
+
+ * test/usepackage.tex: Added \enablehyperlinks (this test depends
+ on hyperlinks being enabled). Added test for \urldef from
+ url.sty.
+
+ * xeplain.tex: Added \protected@edef for \urldef from url.sty.
+ (hldriver@nolinks): The label argument to \hlstart and \hldest
+ must be passed to \write-1 _fully expanded_, otherwise macros that
+ the label uses may become redefined/undefined by the time the page
+ is shipped out and the \write is executed (this resulted in URLs
+ defined with \urldef to fail under the nolinks driver).
+ (@generalref): Use \@generalref@class instead of \temp, since
+ \@generalrefoptarg can possibly trash \temp.

+2005-12-20 Oleg Katsitadze <olegkat@gmail.com>
+
+ * doc/userdef.texi (Contents): Tell that \writetocentry reads
+ \tocfilebasename only once.
+ (Tables): Corrected stale link to lifshitz.ph.utexas.edu.
+ (Packages known to work): Added link to Klaus Hoeppner's article
+ on LaTeX graphics.
+
+ * demo/xhyper.tex:
+ Input ../eplain instead of eplain, in case Eplain is not (yet)
+ properly installed.
+
+ * doc/Makefile:
+ Added _FLAG variables for each program used. Split targets like
+ `pdf eplain.pdf' and made pdf depend on eplain.pdf, etc. (otherwise
+ `make pdf' always rebuilds eplain.pdf). Added rules and dependencies
+ for the demo file images.
+ (ps): New target.
+
+ * Makefile:
+ Added demo subdir. Changed all calls to Make to use $(MAKE).
+ (ps): New target.
+
+ * pdfcrop.pl, demo/Makefile, doc/demo.texi: New files.
+
+ * AUTHORS: Added pdfcrop.pl.
+

+ (Footnote hyperlinks): Showed how to turn off footnote hyperlinks.
+ (Hyperlink driver nolinks): Showed the proper way to
+ \enablehyperlinks for the dual links/nolinks output.
+ (Setting default types and options): Example of how to turn off

+Installation
+************
+
+Your TeX installation should already contain a version of Eplain
+(`eplain.tex') in its main `texmf' tree (usually under
+`/usr/share/texmf/tex/eplain/' on Unix systems). To install a newer
+version of Eplain, put the new `eplain.tex' (included in Eplain
+distributions) in the `tex/eplain/' subdirectory of your local `texmf'
+tree. The newer version you install in the local tree should override
+the older one in the main tree.
+
+ The location of the local `texmf' tree obviously depends on your
+operating system and TeX installation. On Unix systems the usual
+location is `/usr/local/share/texmf/'. If you don't have write
+permissions for `/usr/local/share/texmf/', many installations read the
+`texmf' tree in the user's home directory; `eplain.tex' then should go
+under `~/texmf/tex/eplain/'. For more information about TeX directory
+structure, please see
+`http://www.tex.ac.uk/cgi-bin/texfaq2html?label=tds'.
+
+ If you prefer to install `eplain.tex' in a non-standard place, set
+an environment variable (`TEXINPUTS' for the Web2C port of TeX to Unix)
+to tell TeX how to find it.
+
+ If you want, you can also create a format (`.fmt') file for Eplain,
+which will eliminate the time spent reading the macro source file with
+`\input'. You do this by issuing a sequence of Unix commands something
+like this:
+
+ prompt$ touch eplain.aux
+ prompt$ initex
+ This is TeX, ...
+ **&plain eplain
+ (eplain.tex)
+ *\dump
+ ... MESSAGES ...
+
+You must make sure that `eplain.aux' exists _before_ you run `initex';
+otherwise, warning messages about undefined labels will never be issued.
+
+ You then have to install the resulting `eplain.fmt' in your local
+`texmf' tree or set an environment variable to tell TeX how to find it.
+For the Web2C port of TeX to Unix, format files are usually installed
+under `/usr/local/share/texmf/web2c/' or `/var/lib/texmf/web2c/'; the
+environment variable is `TEXFORMATS'.

This file records noteworthy changes. This file is public domain.
+3.1 (3 December 2006)
+
+General:
+* Rearranged the distro to comply with TDS.
+* Distro now includes PDF, HTML and INFO versions of the manual.
+* Removed etex.tex.
+
+LaTeX packages under Eplain:
+* When reloading LaTeX packages, warn and skip reloading, instead of
+ giving an error. Suggested by Dan Luecking.
+* The primitive \input is now restored after loading LaTeX packages.
+* Added more "LaTeX" defs needed by: the `draft' option to
+ graphic{s,x}.sty; warnings from epstopdf.sty when graphics.sty is
+ not loaded.
+
+Hyperlinks:
+* Added the `hypertex' driver, and made it the default driver.
+* Made footnote hyperlinks off by default.
+* Added the \href macro. Suggested by Dorai Sitaram.
+* LABEL argument of the hyperlink macros now allow special characters
+ like # and ~ (useful for URLs). Suggested by Dorai Sitaram.
+* Fixed a hyperlink-related bug in equation macros.
+* Fixed a bug in the `nolinks' driver.
+* Added \writenumberedtocline macro, which is \writenumberedtocentry
+ with permuted parameters. Suggested by Dorai Sitaram.
+* Hyperlink macros now ignore leading spaces in option lists.
+* All hyperlink macros now report errors until links are enabled.
+
+Cross-references, TOC and indexing:
+* Added warnings about multiply defined xref labels. Suggested by
+ Tomas Penicka.
+* Fixed \definexref to (once again) ignore following spaces.
+* Indexing macros now read TERM, SUBTERM and SEE... arguments
+ verbatim, to allow special characters and catcode changes.
+ Suggested by Dorai Sitaram.
+* Extended the TOC macros: when given an integer for the type of a
+ TOC entry, they write \tocentry{NUM}... to the .toc file. Suggested
+ by Dorai Sitaram.
+
+Programming defs:
+* Added \ifinteger and \isinteger macros.
+* Added \For loop which strips off leading spaces from items.
+
+Manual:
+* Added demo subdir with demo files, and added new chapter `Demo
+ files' to the manual.
+* Documented \ifempty, the extended \loop macro, and the new macros.
+* Many small improvements and additions to the manual.
+
+Other:
+* Added new \nolastlinelisting listing hook which omits the last
+ (empty) line of the file.
+
+
3.0 (20 September 2005)

-Installation
-************
-
-The simplest way to install Eplain is simply to install the file
-`eplain.tex' in a directory where TeX will find it. What that
-directory is obviously depends on your operating system and TeX
-installation. I personally install `eplain.tex' in a directory
-`/usr/local/lib/texmf/tex/plain'.
-
- If you want, you can also create a format (`.fmt') file for Eplain,
-which will eliminate the time spent reading the macro source file with
-`\input'. You do this by issuing a sequence of Unix commands something
-like this:
-
- prompt$ touch eplain.aux
- prompt$ initex
- This is TeX, ...
- **&plain eplain
- (eplain.tex)
- *\dump
- ... MESSAGES ...
-
-You must make sure that `eplain.aux' exists _before_ you run `initex';
-otherwise, warning messages about undefined labels will never be issued.
-
- You then have to install the resulting `eplain.fmt' in some system
-directory or set an environment variable to tell TeX how to find it. I
-install the format files in `/usr/local/lib/texmf/ini'; the environment
-variable for the Web2C port of TeX to Unix is `TEXFORMATS'.
-
- Some implementations of TeX (including Web2C) use the name by which
-TeX is invoked to determine what format to read. For them, you should
-make a link to the `virtex' program named `etex', and then install the
-format file with the name `etex.fmt'. This lets users invoke TeX as
-`etex' and get the format file read automatically, without having to
-say `&eplain'.
-
- For convenience, the file `etex.tex' in the distribution directory
-does `\input eplain' and then `\dump', so that if you replace `eplain'
-with `etex' in the example above, the format file will end up with the
-right name.
-
- The `install' target in the `Makefile' does all this properly for
-Unix systems and Web2C. You may have to change the pathnames.
-
- Under emtex, `eaj@acpub.duke.edu' says that
-
- tex386 -i ^&plain eplain \dump
-
-produces a format file.

-@section Slanted lines and vectors
-
-The macros @code{\drawline}
-@findex drawline
-and @code{\drawvector}
-@findex drawvector
-provide the capability found in @LaTeX{}'s
-@cindex @LaTeX{}
-@cindex picture mode
-picture mode to draw slanted lines and vectors of certain directions.
-Both of these macros take three arguments: two integer arguments to
-specify the direction of the line or vector, and one argument to specify
-its length. For example, @samp{\drawvector(-4,1)@{60pt@}} produces the
-vector
-@iftex
-@tex
-$$\vbox{\hbox{\drawvector(-4,1){60pt}}\smallskip
- \hbox{$\mathop{\hbox to60pt{\leftarrowfill\hskip-5pt\rightarrowfill}}
- \limits_{{\fam0 60\,pt}}$}}$$
-@end tex
-@end iftex
-@ifinfo
-
-@center (A vector in the 2d quadrant of length 60 pt appears here.)
-
-@end ifinfo
-@cindex lines
-@cindex vectors
-which lies in the 2d quadrant, has a slope of minus 1/4, and a width of
-60 pt.
-
-Note that if an @code{\hbox} is placed around @code{\drawline} or
-@code{\drawvector}, then the width of the @code{\hbox} will be the
-positive dimension specified in the third argument, except when a
-vertical line or vector is specified, e.g.,
-@code{\drawline(0,1)@{1in@}}, which has zero width. If the specified
-direction lies in the 1st or 2d quadrant (e.g., @code{(1,1)} or
-@code{(-2,3)}), then the @code{\hbox} will have positive height and zero
-depth. Conversely, if the specified direction lies in the 3d or 4th
-quadrant (e.g., @code{(-1,-1)} or @code{(2,-3)}), then the @code{\hbox}
-will have positive depth and zero height.
-
-There are a finite number of directions that can be specified. For
-@code{\drawline}, the absolute value of each integer defining the
-direction must be less than or equal to six, i.e., @code{(7,-1)} is
-incorrect, but @code{(6,-1)} is acceptable. For @code{\drawvector}, the
-absolute value of each integer must be less than or equal to four.
-Furthermore, the two integers cannot have common divisors; therefore, if
-a line with slope 2 is desired, say @code{(2,1)} instead of
-@code{(4,2)}. Also, specify @code{(1,0)} instead of, say, @code{(3,0)}
-for horizontal lines and likewise for vertical lines.
-
-Finally, these macros depend upon the @LaTeX{} font @code{line10}. If
-your site doesn't have this font, ask your system administrator to get
-it. Future enhancements will include macros to draw dotted lines and
-dotted vectors of various directions.
-
-
-@node Commutative diagrams
-@section Commutative diagrams
-
-@cindex commutative diagrams
-
-The primitive commands @code{\drawline} and @code{\drawvector} can be
-used to typeset arrow theoretic diagrams. This section describes (1)
-macros to facilitate typesetting arrows and morphisms, and (2) macros to
-facilitate the construction of commutative diagrams. All macros
-described in this section must be used in math mode.
-
-@menu
-* Arrows and morphisms::
-* Construction of commutative diagrams::
-* Commutative diagram parameters::
-@end menu
-
-@node Arrows and morphisms
-@subsection Arrows and morphisms
-@cindex arrows
-@cindex morphisms
-
-The macros @code{\mapright} and @code{\mapleft} produce right and left
-@findex mapright
-@findex mapleft
-pointing arrows, respectively. Use superscript (@code{^}) to place a
-morphism above the arrow, e.g., @samp{\mapright^\alpha}; use subscript
-(@code{_}) to place a morphism below the arrow, e.g.,
-@samp{\mapright_@{\tilde l@}}. Superscripts and subscripts may be used
-simulataneously, e.g., @samp{\mapright^\pi_@{\rm epimor.@}}.
-
-Similarly, the macros @code{\mapup} and @code{\mapdown} produce up and
-@findex mapup
-@findex mapdown
-down pointing arrows, respectively. Use @code{\rt}
-@findex rt
-to place a morphism to the right of the arrow, e.g., @samp{\mapup\rt@{\rm
-id@}}; use @code{\lft}
-@findex lft
-to place a morphism to the left of the arrow, e.g., @samp{\mapup\lft\omega}.
-@code{\lft} and @code{\rt} may be used simultaneously, e.g.,
-@samp{\mapdown\lft\pi\rt@{\rm monomor.@}}.
-
-Slanted arrows are produced by the macro @code{\arrow}, which takes
-@findex arrow
-a direction argument (e.g., @samp{\arrow(3,-4)}). Use @code{\rt} and
-@code{\lft} to place morphisms to the right and left, respectively, of
-the arrow. A slanted line (no arrowhead) is produced with the macro
-@code{\sline},
-@findex sline
-whose syntax is identical to that of @code{\arrow}.
-
-The length of these macros is predefined by the default @TeX{}
-dimensions @code{\harrowlength},
-@findex harrowlength
-for horizontal arrows (or lines),
-@code{\varrowlength},
-@findex varrowlength
-for vertical arrows (or lines), and
-@code{\sarrowlength},
-@findex sarrowlength
-for slanted arrows (or lines). To change any of these dimensions, say,
-e.g., @samp{\harrowlength=40pt}. As with all other @TeX{} dimensions,
-the change may be as global or as local as you like. Furthermore, the
-placement of morphisms on the arrows is controlled by the dimensions
-@code{\hmorphposn},
-@findex hmorphposn
-@code{\vmorphposn},
-@findex vmorphposn
-and @code{\morphdist}.
-@findex morphdist
-The first two dimensions control the horizontal and vertical position of
-the morphism from its default position; the latter dimension controls
-the distance of the morphism from the arrow. If you have more than one
-morphism per arrow (i.e., a @code{^}/@code{_} or @code{\lft}/@code{\rt}
-construction), use the parameters
-@code{\hmorphposnup},
-@findex hmorphposnup
-@code{\hmorphposndn},
-@findex hmorphposndn
-@code{\vmorphposnup},
-@findex vmorphposnup
-@code{\vmorphposndn},
-@findex vmorphposndn
-@code{\hmorphposnrt},
-@findex hmorphposnrt
-@code{\hmorphposnlft},
-@findex hmorphposnlft
-@code{\vmorphposnrt},
-@findex vmorphposnrt
-and @code{\vmorphposnlft}.
-@findex vmorphposnlft
-The default values of all these dimensions are provided in the section
-on parameters that follows below.
-
-There is a family of macros to produce horizontal lines, arrows, and
-adjoint arrows. The following macros produce horizontal maps and have
-the same syntax as @code{\mapright}:
-
-@table @code
-
-@item \mapright

-
-The width between double arrows is controlled by the parameter
-@code{\channelwidth}.
-@findex channelwidth
-The parameters @code{\hchannel} and @code{\vchannel}, if nonzero,
-override @code{\channelwidth} by controlling the horizontal and vertical
-shifting from the first arrow to the second.
-
-There are no adornments on these arrows to distinguish inclusions from
-epimorphisms from monomorphisms. Many texts, such as Lang's book
-@cite{Algebra}, use as a tasteful alternative the symbol `inc' (in roman) next
-to an arrow to denote inclusion.
-@cindex Lang, Serge
-
-Future enhancements will include a mechanism to draw curved arrows
-found in, e.g., the Snake Lemma, by employing a version of the
-@code{\path} macros of Appendix D of @cite{The @TeX{}book}.

-@node Construction of commutative diagrams
-@subsection Construction of commutative diagrams
-
-There are two approaches to the construction of commutative diagrams
-described here. The first approach, and the simplest, treats
-commutative diagrams like fancy matrices, as Knuth does in Exercise
-18.46 of @cite{The @TeX{}book}. This case is covered by the macro
-@code{\commdiag},
-@findex commdiag
-which is an altered version of the Plain @TeX{} macro @code{\matrix}.
-@findex matrix
-An example suffices to demonstrate this macro. The following
-commutative diagram (illustrating the covering homotopy property; Bott
-and Tu, @cite{Differential Forms in Algebraic Topology})
-@cindex Bott, Raoul
-@cindex Tu, Loring W.
-@cindex covering homotopy property
-@iftex
-@tex
-$$\commdiag{Y&\mapright^f&E\cr \mapdown&\arrow(3,2)\lft{f_t}&\mapdown\cr
-Y\times I&\mapright^{\bar f_t}&X}$$
-@end tex
-@end iftex
-@ifinfo
-
-@center (A commutative diagram appears here in the printed output.)
-
-@end ifinfo
-is produced with the code
-
-@example
-$$\commdiag@{Y&\mapright^f&E\cr \mapdown&\arrow(3,2)\lft@{f_t@}&\mapdown\cr
-Y\times I&\mapright^@{\bar f_t@}&X@}$$
-@end example
-
-Of course, the parameters may be changed to produce a different effect.
-The following commutative diagram (illustrating the universal mapping
-property; Warner, @cite{Foundations of Differentiable Manifolds and Lie
-Groups})
-@cindex Warner, Frank W.
-@cindex universal mapping property
-@iftex
-@tex
-$$\varrowlength=20pt

-$$\varrowlength=20pt
-\commdiag@{V\otimes W\cr \mapup\lft\phi&\arrow(3,-1)\rt@{\tilde l@}\cr
-V\times W&\mapright^l&U\cr@}$$
-@end example
-
-A diagram containing isosceles triangles is achieved by placing the apex
-of the triangle in the center column, as shown in the example
-(illustrating all constant minimal realizations of a linear system;
-Brockett, @cite{Finite Dimensional Linear Systems})
-@cindex Brockett, Roger W.

-&R^q\cr@}$$
-@end example
-
-Other commutative diagram examples appear in the file
-@code{commdiags.tex}, which is distributed with this package.
-
-In these examples the arrow lengths and line slopes were carefully
-chosen to blend with each other. In the first example, the default
-settings for the arrow lengths are used, but a direction for the arrow
-must be chosen. The ratio of the default horizontal and vertical arrow
-lengths is approximately the golden mean
-@cindex golden mean
-@iftex
-@tex
-$\gamma=1.618\ldots$;
-@end tex
-@end iftex
-@ifinfo
-gamma=1.618...;
-@end ifinfo
-@cindex golden mean
-the arrow direction closest to this mean is @code{(3,2)}. In the second
-example, a slope of
-@iftex
-@tex
-$-1/3$
-@end tex
-@end iftex
-@ifinfo
--1/3
-@end ifinfo
-is desired and the default horizontal arrow length is 60 pt; therefore,
-choose a vertical arrow length of 20 pt. You may affect the interline
-glue settings of @code{\commdiag} by redefining the macro
-@code{\commdiagbaselines}.
-@findex commdiagbaselines
-(cf@. Exercise 18.46 of @cite{The @TeX{}book} and the section on
-parameters below.)
-
-The width, height, and depth of all morphisms are hidden so that the
-morphisms' size do not affect arrow positions. This can cause a large
-morphism at the top or bottom of a diagram to impinge upon the text
-surrounding the diagram. To overcome this problem, use @TeX{}'s
-@code{\noalign} primitive to insert a @code{\vskip} immediately above or
-below the offending line, e.g.,
-@samp{$$\commdiag@{\noalign@{\vskip6pt@}X&\mapright^\int&Y\cr ...@}}.
-
-The macro @code{\commdiag} is too simple to be used for more complicated
-diagrams, which may have intersecting or overlapping arrows. A second
-approach, borrowed from Francis Borceux's @cite{Diagram} macros for
-@LaTeX{}, treats the commutative diagram like a grid of identically
-shaped boxes. To compose the commutative diagram, first draw an equally
-spaced grid, e.g.,
-@cindex grid
-@cindex Borceux, Francis
-@cindex Diagram, macros for LaTeX
-@iftex
-@tex
-$$\def\grid{\cdot&\cdot&\cdot&\cdot&\cdot&\cdot\cr}
-\matrix{\grid\grid\grid\grid}$$
-@end tex
-@end iftex
-@ifinfo
-
-@center . . . . . .
-@center . . . . . .
-@center . . . . . .
-@center . . . . . .
-
-@end ifinfo
-on a piece of scratch paper. Then draw each element (vertices and
-arrows) of the commutative diagram on this grid, centered at each
-grid point. Finally, use the macro @code{\gridcommdiag}
-@findex gridcommdiag
-to implement your design as a @TeX{} alignment. For example, the cubic
-diagram
-@cindex cube
-@iftex
-@tex
-$$\harrowlength=48pt \varrowlength=48pt \sarrowlength=20pt

-that appears in Francis Borceux's documentation can be implemented on
-a 7 by 7 grid, and is achieved with the code
-
-@example
-$$\harrowlength=48pt \varrowlength=48pt \sarrowlength=20pt
-\def\cross#1#2@{\setbox0=\hbox@{$#1$@}%
- \hbox to\wd0@{\hss\hbox@{$#2$@}\hss@}\llap@{\unhbox0@}@}
-\gridcommdiag@{&&B&&\mapright^b&&D\cr

-\mapdown\lft e&&F&&\cross@{\hmorphposn=-12pt\mapright_j@}
-@{\vmorphposn=12pt\mapdown\rt g@}&&H\cr
-&\arrow(1,1)\lft i&&&&\arrow(1,1)\rt l\cr
-E&&\mapright_k&&G\cr@}$$
-@end example
-
-The dimensions @code{\hgrid} and @code{\vgrid}
-@findex hgrid
-@findex vgrid
-control the horizontal and vertical spacing of the grid used by
-@code{\gridcommdiag}. The default setting for both of these dimensions
-is 15 pt. Note that in the example of the cube the arrow lengths must
-be adjusted so that the arrows overlap into neighboring boxes by the
-desired amount. Hence, the @code{\gridcommdiag} method, albeit more
-powerful, is less automatic than the simpler @code{\commdiag} method.
-Furthermore, the ad hoc macro @code{\cross} is introduced to allow the
-effect of overlapping arrows. Finally, note that the positions of four
-of the morphisms are adjusted by setting @code{\hmorphposn} and
-@code{\vmorphposn}.
-
-One is not restricted to a square grid. For example, the proof of
-Zassenhaus's Butterfly Lemma can be illustrated by the diagram (appearing
-in Lang's book @cite{Algebra})

-
-Again, the construction of this diagram requires careful choices for the
-arrow lengths and is facilitated by the introduction of the ad hoc
-macros @code{\cross}, @code{\r}, and @code{\l}. Note also that

-@iftex

-$u(U\cap v)$ and $(u\cap V)v$.

-Many diagrams may be typeset with the predefined macros that appear
-here; however, ingenuity is often required to handle special cases.

-\section{Overview}
-
-[This document will be expanded when \BibTeX\ version 1.00 comes out.
-Please report typos, omissions, inaccuracies,
-and especially unclear explanations
-to me ({\tt patashnik@SCORE.STANFORD.EDU}).
-Suggestions for improvements are wanted and welcome.]
-
-This documentation, for \BibTeX\ version 0.99b,
-is meant for general \BibTeX\ users;
-bibliography-style designers should read this document
-and then read ``Designing \BibTeX\ Styles''~\cite{btxhak},
-which is meant for just them.
-
-This document has three parts:
-Section~\ref{differences}
-describes the differences between versions 0.98i and 0.99b
-of \BibTeX\ and between the corresponding versions of the standard styles;
-Section~\ref{latex-appendix}
-updates Appendix~B.2 of the \LaTeX\ book~\cite{latex};
-and Section~\ref{odds-and-ends}
-gives some general and specific tips
-that aren't documented elsewhere.
-It's assumed throughout that you're familiar with
-the relevant sections of the \LaTeX\ book.
-
-This documentation also serves as sample input to help
-\BibTeX\ implementors get it running.
-For most documents, this one included, you produce the reference list by:
-running \LaTeX\ on the document (to produce the {\tt aux} file(s)),
-then running \BibTeX\ (to produce the {\tt bbl} file),
-then \LaTeX\ twice more (first to find the information in the {\tt bbl} file
-and then to get the forward references correct).
-In very rare circumstances you may need an extra \BibTeX/\LaTeX\ run.
-
-\BibTeX\ version 0.99b should be used with \LaTeX\ version 2.09,
-for which the closed bibliography format is the default;
-to get the open format, use the optional document style {\tt openbib}
-(in an open format there's a line break between major blocks of a
-reference-list entry; in a closed format the blocks run together).]
-
-Note: \BibTeX\ 0.99b is not compatible with the old style files;
-nor is \BibTeX\ 0.98i compatible with the new ones
-(the new \BibTeX, however, is compatible with old database files).
-
-Note for implementors: \BibTeX\ provides logical-area names
-\hbox{\tt TEXINPUTS:} for bibliography-style files and
-\hbox{\tt TEXBIB:} for database files it can't otherwise find.

-This section describes the differences between
-\BibTeX\ versions 0.98i and 0.99b, and also between
-the corresponding standard styles.
-There were a lot of differences;
-there will be a lot fewer between 0.99 and 1.00.

-\subsection{New \BibTeX\ features}
-\label{features}
-
-The following list explains \BibTeX's new features and how to use them.
-\begin{enumerate}
-
-\item
-With the single command `\hbox{\verb|\nocite{*}|}'
-you can now include in the reference list
-every entry in the database files, without having to explicitly
-\verb|\cite| or \hbox{\verb|\nocite|} each entry.
-Giving this command, in essence,
-\hbox{\verb|\nocite|}s
-all the enties in the database, in database order,
-at the very spot in your document
-where you give the command.
-
-\item
-\label{concat}
-You can now have as a field value (or an {\tt @STRING} definition)
-the concatenation of several strings.
-For example if you've defined
-\begin{verbatim}
- @STRING( WGA = " World Gnus Almanac" )
-\end{verbatim}
-then it's easy to produce nearly-identical
-{\tt title} fields for different entries:
-\begin{verbatim}
- @BOOK(almanac-66,
- title = 1966 # WGA,
- . . .
- @BOOK(almanac-67,
- title = 1967 # WGA,
-\end{verbatim}
-and so on. Or, you could have a field like
-\begin{verbatim}
- month = "1~" # jan,
-\end{verbatim}
-which would come out something like
-`\hbox{\verb|1~January|}' or `\hbox{\verb|1~Jan.|}' in the {\tt bbl} file,
-depending on how your bibliography style defines
-the {\tt jan} abbreviation.
-You may concatenate as many strings as you like
-(except that there's a limit to the overall length
-of the resulting field);
-just be sure to put the concatenation character `{\tt\#}'$\!$,
-surrounded by optional spaces or newlines,
-between each successive pair of strings.
-
-\item
-\BibTeX\ has a new cross-referencing feature,
-explained by an example.
-Suppose you say \hbox{\verb|\cite{no-gnats}|} in your document,
-and suppose you have these two entries in your database file:
-\begin{verbatim}
- @INPROCEEDINGS(no-gnats,
- crossref = "gg-proceedings",
- author = "Rocky Gneisser",
- title = "No Gnats Are Taken for Granite",
- pages = "133-139")
- . . .
- @PROCEEDINGS(gg-proceedings,
- editor = "Gerald Ford and Jimmy Carter",
- title = "The Gnats and Gnus 1988 Proceedings",
- booktitle = "The Gnats and Gnus 1988 Proceedings")
-\end{verbatim}
-Two things happen.
-First, the special \hbox{\tt crossref} field tells \BibTeX\
-that the \hbox{\tt no-gnats} entry should inherit
-any fields it's missing from
-the entry it cross references, \hbox{\tt gg-proceedings}.
-In this case it in inherits the two fields
-\hbox{\tt editor} and \hbox{\tt booktitle}.
-Note that, in the standard styles at least,
-the \hbox{\tt booktitle} field is irrelevant
-for the \hbox{\tt PROCEEDINGS} entry type.
-The \hbox{\tt booktitle} field appears here
-in the \hbox{\tt gg-proceedings} entry
-only so that the entries that cross reference it
-may inherit the field.
-No matter how many papers from this meeting exist in the database,
-this \hbox{\tt booktitle} field need only appear once.
-
-The second thing that happens:
-\BibTeX\ automatically puts the entry \hbox{\tt gg-proceedings}
-into the reference list if it's cross
-referenced by two or more entries that you
-\verb|\cite| or \hbox{\verb|\nocite|},
-even if you don't \verb|\cite| or \hbox{\verb|\nocite|}
-the \hbox{\tt gg-proceedings} entry itself.
-So \hbox{\tt gg-proceedings} will automatically appear
-on the reference list if one other entry
-besides \hbox{\tt no-gnats} cross references it.
-
-To guarantee that this scheme works, however,
-a cross-referenced entry must occur later in the database files
-than every entry that cross-references it.
-Thus, putting all cross-referenced entries at the end makes sense.
-(Moreover, you may not reliably nest cross references;
-that is, a cross-referenced entry may
-not itself reliably cross reference an entry.
-This is almost certainly not something you'd
-want to do, though.)
-
-One final note:
-This cross-referencing feature is completely unrelated
-to the old \BibTeX's cross referencing,
-which is still allowed.
-Thus, having a field like
-\begin{verbatim}
- note = "Jones \cite{jones-proof} improves the result"
-\end{verbatim}
-is not affected by the new feature.
-
-\item
-\BibTeX\ now handles accented characters.
-For example if you have an entry with the two fields
-\begin{verbatim}
- author = "Kurt G{\"o}del",
- year = 1931,
-\end{verbatim}
-and if you're using the \hbox{\tt alpha} bibliography style,
-then \BibTeX\ will construct the label
-\hbox{[G{\"o}d31]} for this entry, which is what you'd want.
-To get this feature to work you must place the entire accented
-character in braces;
-in this case either \hbox{\verb|{\"o}|}
-or \hbox{\verb|{\"{o}}|} will do.
-Furthermore these braces must not themselves be
-enclosed in braces (other than the ones that might delimit
-the entire field or the entire entry);
-and there must be a backslash
-as the very first character inside the braces.
-Thus neither \hbox{\verb|{G{\"{o}}del}|}
-nor \hbox{\verb|{G\"{o}del}|} will work for this example.
-
-This feature handles all the accented characters and
-all but the nonbackslashed foreign symbols found in Tables
-3.1 and~3.2 of the \LaTeX\ book.
-This feature behaves similarly for ``accents'' you might define;
-we'll see an example shortly.
-For the purposes of counting letters in labels,
-\BibTeX\ considers everything contained inside the braces
-as a single letter.
-
-\item
-\BibTeX\ also handles hyphenated names.
-For example if you have an entry with
-\begin{verbatim}
- author = "Jean-Paul Sartre",
-\end{verbatim}
-and if you're using the \hbox{\tt abbrv} style,
-then the result is `J.-P. Sartre'$\!$.
-
-\item
-\label{preamble}
-There's now an \hbox{\verb|@PREAMBLE|} command
-for the database files.
-This command's syntax is just like \hbox{\verb|@STRING|}'s,
-except that there is no name or equals-sign, just the string.
-Here's an example:
-\begin{verbatim}
- @PREAMBLE{ "\newcommand{\noopsort}[1]{} "
- # "\newcommand{\singleletter}[1]{#1} " }
-\end{verbatim}
-(note the use of concatenation here, too).
-The standard styles output whatever information you give this command
-(\LaTeX\ macros most likely) directly to the {\tt bbl} file.
-We'll look at one possible use of this command,
-based on the \hbox{\verb|\noopsort|} command just defined.
-
-The issue here is sorting (alphabetizing).
-\BibTeX\ does a pretty good job,
-but occasionally weird circumstances conspire to confuse \BibTeX:
-Suppose that you have entries in your database for
-the two books in a two-volume set by the same author,
-and that you'd like volume~1 to appear
-just before volume~2 in your reference list.
-Further suppose that there's now a second edition of volume~1,
-which came out in 1973, say,
-but that there's still just one edition of volume~2,
-which came out in 1971.
-Since the {\tt plain} standard style
-sorts by author and then year,
-it will place volume~2 first
-(because its edition came out two years earlier)
-unless you help \BibTeX.
-You can do this by using the {\tt year} fields below
-for the two volumes:
-\begin{verbatim}
- year = "{\noopsort{a}}1973"
- . . .
- year = "{\noopsort{b}}1971"
-\end{verbatim}
-According to the definition of \hbox{\verb|\noopsort|},
-\LaTeX\ will print nothing but the true year for these fields.
-But \BibTeX\ will be perfectly happy pretending that
-\hbox{\verb|\noopsort|} specifies some fancy accent
-that's supposed to adorn the `a' and the~`b';
-thus when \BibTeX\ sorts it will pretend that
-`a1973' and `b1971' are the real years,
-and since `a' comes before~`b'$\!$, it will place volume~1 before volume~2,
-just what you wanted.
-By the way, if this author has any other works included
-in your database, you'd probably want to use instead something like
-\hbox{\verb|{\noopsort{1968a}}1973|} and
-\hbox{\verb|{\noopsort{1968b}}1971|},
-so that these two books would come out in a reasonable spot
-relative to the author's other works
-(this assumes that 1968 results in a reasonable spot,
-say because that's when the first edition of volume~1 appeared).
-
-There is a limit to the number of \hbox{\verb|@PREAMBLE|} commands
-you may use, but you'll never exceed this limit if
-you restrict yourself to one per database file;
-this is not a serious restriction,
-given the concatenation feature (item~\ref{concat}).
-
-\item
-\BibTeX's sorting algorithm is now stable.
-This means that if two entries have identical sort keys,
-those two entries will appear in citation order.
-(The bibliography styles construct these sort keys---%
-usually the author information followed by the year and the title.)
-
-\item
-\BibTeX\ no longer does case conversion for file names;
-this will make \BibTeX\ easier to install on Unix systems, for example.
-
-\item
-It's now easier to add code for processing a
-command-line {\tt aux}-file name.
-
-\end{enumerate}
-
-
-\subsection{Changes to the standard styles}
-
-This section describes changes to the standard styles
-({\tt plain}, {\tt unsrt}, {\tt alpha}, {\tt abbrv})
-that affect ordinary users.
-Changes that affect style designers appear in
-the document ``Designing \BibTeX\ Styles''~\cite{btxhak}.
-\begin{enumerate}
-
-\item
-In general, sorting is now by ``author''$\!$, then year, then title---%
-the old versions didn't use the year field.
-(The {\tt alpha} style, however, sorts first by label,
-then ``author''$\!$, year, and title.)
-The quotes around author mean that some entry types
-might use something besides the author, like the editor or organization.
-
-\item
-Many unnecessary ties (\verb|~|) have been removed.
-\LaTeX\ thus will produce slightly fewer
-`\hbox{\tt Underfull} \verb|\hbox|' messages
-when it's formatting the reference list.
-
-\item
-Emphasizing (\hbox{\verb|{\em ...}|})
-has replaced italicizing (\hbox{\verb|{\it ...}|}).
-This will almost never result in a difference
-between the old output and the new.
-
-\item
-The {\tt alpha} style now uses a superscripted~`$^{+}$' instead of a~`*'
-to represent names omitted in constructing the label.
-If you really liked it the way it was, however,
-or if you want to omit the character entirely,
-you don't have to modify the style file---%
-you can override the~`$^{+}$' by
-redefining the \hbox{\verb|\etalchar|} command
-that the {\tt alpha} style writes onto the {\tt bbl} file
-(just preceding the \hbox{\verb|\thebibliography|} environment);
-use \LaTeX's \hbox{\verb|\renewcommand|} inside
-a database \hbox{\tt @PREAMBLE} command,
-described in the previous subsection's item~\ref{preamble}.
-
-\item
-The {\tt abbrv} style now uses `Mar.' and `Sept.'\
-for those months rather than `March' and `Sep.'
-
-\item
-The standard styles use \BibTeX's new cross-referencing feature
-by giving a \verb|\cite| of the cross-referenced entry and by
-omitting from the cross-referencing entry
-(most of the) information that appears
-in the cross-referenced entry.
-These styles do this when
-a titled thing (the cross-referencing entry)
-is part of a larger titled thing (the cross-referenced entry).
-There are five such situations:
-when (1)~an \hbox{\tt INPROCEEDINGS}
-(or \hbox{\tt CONFERENCE}, which is the same)
-cross references a \hbox{\tt PROCEEDINGS};
-when (2)~a {\tt BOOK}, (3)~an \hbox{\tt INBOOK},
-or (4)~an \hbox{\tt INCOLLECTION}
-cross references a {\tt BOOK}
-(in these cases, the cross-referencing entry is a single
-volume in a multi-volume work);
-and when (5)~an \hbox{\tt ARTICLE}
-cross references an \hbox{\tt ARTICLE}
-(in this case, the cross-referenced entry is really a journal,
-but there's no \hbox{\tt JOURNAL} entry type;
-this will result in warning messages about
-an empty \hbox{\tt author} and \hbox{\tt title} for the journal---%
-you should just ignore these warnings).
-
-\item
-The \hbox{\tt MASTERSTHESIS} and \hbox{\tt PHDTHESIS}
-entry types now take an optional {\tt type} field.
-For example you can get the standard styles to
-call your reference a `Ph.D.\ dissertation'
-instead of the default `PhD thesis' by including a
-\begin{verbatim}
- type = "{Ph.D.} dissertation"
-\end{verbatim}
-in your database entry.
-
-\item
-Similarly, the \hbox{\tt INBOOK} and \hbox{\tt INCOLLECTION}
-entry types now take an optional {\tt type} field,
-allowing `section~1.2' instead of the default `chapter~1.2'$\!$.
-You get this by putting
-\begin{verbatim}
- chapter = "1.2",
- type = "Section"
-\end{verbatim}
-in your database entry.
-
-\item
-The \hbox{\tt BOOKLET}, \hbox{\tt MASTERSTHESIS},
-and \hbox{\tt TECHREPORT} entry types now format
-their \hbox{\tt title} fields as if they were
-\hbox{\tt ARTICLE} \hbox{\tt title}s
-rather than \hbox{\tt BOOK} \hbox{\tt title}s.
-
-\item
-The \hbox{\tt PROCEEDINGS} and \hbox{\tt INPROCEEDINGS}
-entry types now use the \hbox{\tt address} field
-to tell where a conference was held,
-rather than to give the address
-of the publisher or organization.
-If you want to include the
-publisher's or organization's address,
-put it in the \hbox{\tt publisher}
-or \hbox{\tt organization} field.
-
-\item
-The \hbox{\tt BOOK}, \hbox{\tt INBOOK}, \hbox{\tt INCOLLECTION},
-and \hbox{\tt PROCEEDINGS} entry types now allow either
-\hbox{\tt volume} or \hbox{\tt number} (but not both),
-rather than just \hbox{\tt volume}.
-
-\item
-The \hbox{\tt INCOLLECTION} entry type now allows
-a \hbox{\tt series} and an \hbox{\tt edition} field.
-
-\item
-The \hbox{\tt INPROCEEDINGS} and \hbox{\tt PROCEEDINGS}
-entry types now allow either a \hbox{\tt volume} or \hbox{\tt number},
-and also a \hbox{\tt series} field.
-
-\item
-The \hbox{\tt UNPUBLISHED} entry type now outputs,
-in one block, the \hbox{\tt note} field
-followed by the date information.
-
-\item
-The \hbox{\tt MANUAL} entry type now prints out
-the \hbox{\tt organization} in the first block
-if the \hbox{\tt author} field is empty.
-
-\item
-The {\tt MISC} entry type now issues a warning
-if all the optional fields are empty
-(that is, if the entire entry is empty).
-
-\end{enumerate}
-
-
-\section{The Entries}
-\label{latex-appendix}
-
-This section is simply a corrected version of
-Appendix~B.2 of the \LaTeX\ book~\cite{latex},
-\copyright~1986, by Addison-Wesley.
-The basic scheme is the same, only a few details have changed.
-
-
-\subsection{Entry Types}
-
-When entering a reference in the database, the first thing to decide
-is what type of entry it is. No fixed classification scheme can be
-complete, but \BibTeX\ provides enough entry types to handle almost
-any reference reasonably well.
-
-References to different types of publications contain different
-information; a reference to a journal article might include the volume
-and number of the journal, which is usually not meaningful for a book.
-Therefore, database entries of different types have different fields.
-For each entry type, the fields are divided into three classes:
-\begin{description}
-
-\item[required]
-Omitting the field will produce a warning message
-and, rarely, a badly formatted bibliography entry.
-If the required information is not meaningful,
-you are using the wrong entry type.
-However, if the required information is meaningful
-but, say, already included is some other field,
-simply ignore the warning.
-
-\item[optional]
-The field's information will be used if present,
-but can be omitted without causing any formatting problems.
-You should include the optional field if it will help the reader.
-
-\item[ignored]
-The field is ignored.
-\BibTeX\ ignores any field that is not required or optional, so you can include
-any fields you want in a \hbox{\tt bib} file entry. It's a good idea
-to put all relevant information about
-a reference in its \hbox{\tt bib} file entry---even information that
-may never appear in the bibliography. For example, if you want to
-keep an abstract of a paper in a computer file, put it in an \hbox{\tt
-abstract} field in the paper's \hbox{\tt bib} file entry. The
-\hbox{\tt bib} file is likely to be as good a place as any for the
-abstract, and it is possible to design a bibliography style for
-printing selected abstracts.
-Note: Misspelling a field name will
-result in its being ignored,
-so watch out for typos
-(especially for optional fields,
-since \BibTeX\ won't warn you when those are missing).
-
-\end{description}
-
-The following are the standard entry types, along with their required
-and optional fields, that are used by the standard bibliography styles.
-The fields within each class (required or optional)
-are listed in order of occurrence in the output,
-except that a few entry types may perturb the order slightly,
-depending on what fields are missing.
-These entry types are similar to those adapted by Brian Reid
-from the classification scheme of van~Leunen~\cite{van-leunen}
-for use in the {\em Scribe\/} system.
-The meanings of the individual fields are explained in the next section.
-Some nonstandard bibliography styles may ignore some optional fields
-in creating the reference.
-Remember that, when used in the \hbox{\tt bib}
-file, the entry-type name is preceded by an \hbox{\tt @} character.

-
-In addition to the fields listed above, each entry type also has an
-optional \hbox{\tt key} field, used in some styles
-for alphabetizing, for cross referencing,
-or for forming a \hbox{\verb|\bibitem|} label.
-You should include a \hbox{\tt key} field for any entry whose
-``author'' information is missing;
-the ``author'' information is usually the \hbox{\tt author} field,
-but for some entry types it can be the \hbox{\tt editor}
-or even the \hbox{\tt organization} field
-(Section~\ref{odds-and-ends} describes this in more detail).
-Do not confuse the \hbox{\tt key} field with the key that appears in the
-\hbox{\verb|\cite|} command and at the beginning of the database entry;
-this field is named ``key'' only for compatibility with {\it Scribe}.
-
-
-\subsection{Fields}
-
-Below is a description of all fields
-recognized by the standard bibliography styles.
-An entry can also contain other fields, which are ignored by those styles.
-\begin{description}
-
-\item[address\hfill]
-Usually the address of the \hbox{\tt publisher} or other type
-of institution.
-For major publishing houses,
-van~Leunen recommends omitting the information entirely.
-For small publishers, on the other hand, you can help the
-reader by giving the complete address.
-
-\item[annote\hfill]
-An annotation.
-It is not used by the standard bibliography styles,
-but may be used by others that produce an annotated bibliography.
-
-\item[author\hfill]
-The name(s) of the author(s),
-in the format described in the \LaTeX\ book.
-
-\item[booktitle\hfill]
-Title of a book, part of which is being cited.
-See the \LaTeX\ book for how to type titles.
-For book entries, use the \hbox{\tt title} field instead.
-
-\item[chapter\hfill]
-A chapter (or section or whatever) number.
-
-\item[crossref\hfill]
-The database key of the entry being cross referenced.
-
-\item[edition\hfill]
-The edition of a book---for example, ``Second''$\!$.
-This should be an ordinal, and
-should have the first letter capitalized, as shown here;
-the standard styles convert to lower case when necessary.
-
-\item[editor\hfill]
-Name(s) of editor(s), typed as indicated in the \LaTeX\ book.
-If there is also an \hbox{\tt author} field, then
-the \hbox{\tt editor} field gives the editor of the book or collection
-in which the reference appears.
-
-\item[howpublished\hfill]
-How something strange has been published.
-The first word should be capitalized.
-
-\item[institution\hfill]
-The sponsoring institution of a technical report.
-
-\item[journal\hfill]
-A journal name.
-Abbreviations are provided for many journals; see the {\it Local Guide}.
-
-\item[key\hfill]
-Used for alphabetizing, cross referencing, and creating a label when
-the ``author'' information
-(described in Section~\ref{odds-and-ends}) is missing.
-This field should not be confused with the key that appears in the
-\hbox{\verb|\cite|} command and at the beginning of the database entry.
-
-\item[month\hfill]
-The month in which the work was
-published or, for an unpublished work, in which it was written.
-You should use the standard three-letter abbreviation,
-as described in Appendix B.1.3 of the \LaTeX\ book.
-
-\item[note\hfill]
-Any additional information that can help the reader.
-The first word should be capitalized.
-
-\item[number\hfill]
-The number of a journal, magazine, technical report,
-or of a work in a series.
-An issue of a journal or magazine is usually
-identified by its volume and number;
-the organization that issues a
-technical report usually gives it a number;
-and sometimes books are given numbers in a named series.
-
-\item[organization\hfill]
-The organization that sponsors a conference or that publishes a \hbox{manual}.
-
-\item[pages\hfill]
-One or more page numbers or range of numbers,
-such as \hbox{\tt 42--111} or \hbox{\tt 7,41,73--97} or \hbox{\tt 43+}
-(the `{\tt +}' in this last example indicates pages following
-that don't form a simple range).
-To make it easier to maintain {\em Scribe\/}-compatible databases,
-the standard styles convert a single dash (as in \hbox{\tt 7-33})
-to the double dash used in \TeX\ to denote number ranges
-(as in \hbox{\tt 7--33}).
-
-\item[publisher\hfill]
-The publisher's name.

-The name of the school where a thesis was written.
-
-\item[series\hfill]
-The name of a series or set of books.
-When citing an entire book, the the \hbox{\tt title} field
-gives its title and an optional \hbox{\tt series} field gives the
-name of a series or multi-volume set
-in which the book is published.
-
-\item[title\hfill]
-The work's title, typed as explained in the \LaTeX\ book.

-The type of a technical report---for example,
-``Research Note''$\!$.
-
-\item[volume\hfill]
-The volume of a journal or multivolume book.
-
-\item[year\hfill]
-The year of publication or, for
-an unpublished work, the year it was written.
-Generally it should consist of four numerals, such as {\tt 1984},
-although the standard styles can handle any {\tt year} whose

-\section{Helpful Hints}
-\label{odds-and-ends}
-
-This section gives some random tips
-that aren't documented elsewhere,
-at least not in this detail.
-They are, roughly, in order
-of least esoteric to most.
-First, however, a brief spiel.
-
-I understand that there's often little choice in choosing
-a bibliography style---journal~$X$ says you must use style~$Y$
-and that's that.
-If you have a choice, however, I strongly recommend that you
-choose something like the {\tt plain} standard style.
-Such a style, van~Leunen~\cite{van-leunen} argues convincingly,
-encourages better writing than the alternatives---%
-more concrete, more vivid.
-
-{\em The Chicago Manual of Style\/}~\cite{chicago},
-on the other hand,
-espouse the author-date system,
-in which the citation might appear in the text as `(Jones, 1986)'$\!$.
-I argue that this system,
-besides cluttering up the
-text with information that may or may not be relevant,
-encourages the passive voice and vague writing.
-Furthermore the strongest arguments for
-using the author-date system---like ``it's the most practical''---%
-fall flat on their face with the advent
-of computer-typesetting technology.
-For instance the {\em Chicago Manual\/} contains,
-right in the middle of page~401, this anachronism:
-``The chief disadvantage of [a style like {\tt plain}] is that additions
-or deletions cannot be made after the manuscript is typed without changing
-numbers in both text references and list.''
-\LaTeX, obviously, sidesteps the disadvantage.
-
-Finally, the logical deficiencies of the author-date style
-are quite evident once you've written a program to implement it.
-For example, in a large bibliography,
-using the standard alphabetizing scheme,
-the entry for `(Aho et~al., 1983b)'
-might be half a page later than the one for `(Aho et~al., 1983a)'$\!$.
-Fixing this problem results in even worse ones.
-What a mess.
-(I have, unfortunately, programmed such a style,
-and if you're saddled with an unenlightened publisher
-or if you don't buy my propaganda,
-it's available from the Rochester style collection.)
-
-Ok, so the spiel wasn't very brief;
-but it made me feel better,
-and now my blood pressure is back to normal.
-Here are the tips for using \BibTeX\
-with the standard styles
-(although many of them hold for nonstandard styles, too).
-\begin{enumerate}
-
-\item
-With \BibTeX's style-designing language
-you can program general database manipulations,
-in addition to bibliography styles.
-For example it's a fairly easy task for someone familiar with the language
-to produce a database-key/author index of all the entries in a database.
-Consult the {\em Local Guide\/} to see
-what tools are available on your system.
-
-\item
-The standard style's thirteen entry types
-do reasonably well at formatting most entries,
-but no scheme with just thirteen formats
-can do everything perfectly.
-Thus, you should feel free to be creative
-in how you use these entry types
-(but if you have to be too creative,
-there's a good chance you're using the wrong entry type).
-
-\item
-Don't take the field names too seriously.
-Sometimes, for instance, you might have to include
-the publisher's address along with the publisher's name
-in the \hbox{\tt publisher} field,
-rather than putting it in the \hbox{\tt address} field.
-Or sometimes, difficult entries work best when you
-make judicious use of the {\tt note} field.
-
-\item
-Don't take the warning messages too seriously.
-Sometimes, for instance, the year appears in the title,
-as in {\em The 1966 World Gnus Almanac}.
-In this case it's best to omit the {\tt year} field
-and to ignore \BibTeX's warning message.
-
-\item
-If you have too many names to list in an
-\hbox{\tt author} or \hbox{\tt editor} field,
-you can end the list with ``and others'';
-the standard styles appropriately append an ``et~al.''
-
-\item
-In general, if you want to keep \BibTeX\ from changing
-something to lower case, you enclose it in braces.
-You might not get the effect you want, however,
-if the very first character after the left brace is a backslash.
-The ``special characters'' item later in this section explains.
-
-\item
-For {\em Scribe\/} compatibility, the database files
-allow an \hbox{\tt @COMMENT} command; it's not really
-needed because \BibTeX\ allows in the database files
-any comment that's not within an entry.
-If you want to comment out an entry,
-simply remove the `{\tt @}' character preceding the entry type.
-
-\item
-The standard styles have journal abbreviations that are
-computer-science oriented;
-these are in the style files primarily for the example.
-If you have a different set of journal abbreviations,
-it's sensible to put them in \hbox{\tt @STRING} commands
-in their own database file and to list this database file
-as an argument to \LaTeX's \hbox{\verb|\bibliography|} command
-(but you should list this argument before the ones that
-specify real database entries).
-
-\item
-It's best to use the three-letter abbreviations for the month,
-rather than spelling out the month yourself.
-This lets the bibliography style be consistent.
-And if you want to include information for the day of the month,
-the {\tt month} field is usually the best place.
-For example
-\begin{verbatim}
- month = jul # "~4,"
-\end{verbatim}
-will probably produce just what you want.
-
-\item
-If you're using the \hbox{\tt unsrt} style
-(references are listed in order of citation)
-along with the \hbox{\verb|\nocite{*}|} feature
-(all entries in the database are included),
-the placement of the \hbox{\verb|\nocite{*}|} command
-within your document file will determine the reference order.
-According to the rule given in Section~\ref{features}:
-If the command is placed at the beginning of the document,
-the entries will be listed in exactly the order
-they occur in the database;
-if it's placed at the end,
-the entries that you explicitly
-\hbox{\verb|\cite|} or \hbox{\verb|\nocite|}
-will occur in citation order,
-and the remaining database entries will be in database order.
-
-\item
-For theses, van Leunen recommends not giving
-the school's department after the name of the degree,
-since schools, not departments, issue degrees.
-If you really think that giving the department information
-will help the reader find the thesis,
-put that information in the \hbox{\tt address} field.
-
-\item
-The \hbox{\tt MASTERSTHESIS} and \hbox{\tt PHDTHESIS} entry types
-are so named for {\em Scribe\/} compatibility;
-\hbox{\tt MINORTHESIS} and \hbox{\tt MAJORTHESIS}
-probably would have been better names.
-Keep this in mind when trying to classify
-a non-U.S.\ thesis.
-
-\item
-Here's yet another suggestion for what to do when an author's
-name appears slightly differently in two publications.
-Suppose, for example, two journals articles use these fields.
-\begin{verbatim}
- author = "Donald E. Knuth"
- . . .
- author = "D. E. Knuth"
-\end{verbatim}
-There are two possibilities.
-You could (1)~simply leave them as is,
-or (2)~assuming you know for sure that
-these authors are one and the same person,
-you could list both in the form that the author prefers
-(say, `Donald~E.\ Knuth').
-In the first case, the entries might be alphabetized incorrectly,
-and in the second, the slightly altered name might
-foul up somebody's electronic library search.
-But there's a third possibility, which is the one I prefer.
-You could convert the second journal's field to
-\begin{verbatim}
- author = "D[onald] E. Knuth"
-\end{verbatim}
-This avoids the pitfalls of the previous two solutions,
-since \BibTeX\ alphabetizes this as if the brackets weren't there,
-and since the brackets clue the reader in that a full first name
-was missing from the original.
-Of course it introduces another pitfall---`D[onald]~E.\ Knuth' looks ugly---%
-but in this case I think the increase in accuracy outweighs
-the loss in aesthetics.
-
-\item
-\LaTeX's comment character `{\tt\%}' is not a comment character
-in the database files.
-
-\item
-Here's a more complete description of
-the ``author'' information referred to in previous sections.
-For most entry types the ``author'' information
-is simply the \hbox{\tt author} field.
-However:
-For the \hbox{\tt BOOK} and \hbox{\tt INBOOK} entry types
-it's the \hbox{\tt author} field, but if there's no author
-then it's the \hbox{\tt editor} field;
-for the \hbox{\tt MANUAL} entry type
-it's the \hbox{\tt author} field, but if there's no author
-then it's the \hbox{\tt organization} field;
-and for the \hbox{\tt PROCEEDINGS} entry type
-it's the \hbox{\tt editor} field, but if there's no editor
-then it's the \hbox{\tt organization} field.
-
-\item
-When creating a label,
-the \hbox{\tt alpha} style uses the ``author'' information described above,
-but with a slight change---%
-for the \hbox{\tt MANUAL} and \hbox{\tt PROCEEDINGS} entry types,
-the {\tt key} field takes precedence over the \hbox{\tt organization} field.
-Here's a situation where this is useful.
-\begin{verbatim}
- organization = "The Association for Computing Machinery",
- key = "ACM"
-\end{verbatim}
-Without the {\tt key} field, the \hbox{\tt alpha} style
-would make a label from the first three letters of information
-in the \hbox{\tt organization} field;
-\hbox{\tt alpha} knows to strip off the `\hbox{\tt The }'$\!$,
-but it would still form a label like `\hbox{[Ass86]}'$\!$,
-which, however intriguing, is uninformative.
-Including the {\tt key} field, as above,
-would yield the better label `\hbox{[ACM86]}'$\!$.
-
-You won't always need the {\tt key} field to override the
-\hbox{\tt organization}, though:
-With
-\begin{verbatim}
- organization = "Unilogic, Ltd.",
-\end{verbatim}
-for instance, the \hbox{\tt alpha} style would
-form the perfectly reasonable label `\hbox{[Uni86]}'$\!$.
-
-\item
-Section~\ref{features} discusses accented characters.
-To \BibTeX, an accented character is really a special case
-of a ``special character''$\!$,
-which consists of everything from a left brace at the top-most level,
-immediately followed by a backslash,
-up through the matching right brace.
-For example in the field
-\begin{verbatim}
- author = "\AA{ke} {Jos{\'{e}} {\'{E}douard} G{\"o}del"
-\end{verbatim}
-there are just two special characters,
-`\hbox{\verb|{\'{E}douard}|}' and `\hbox{\verb|{\"o}|}'
-(the same would be true if the pair of double quotes
-delimiting the field were braces instead).
-In general, \BibTeX\ will not do any processing
-of a \TeX\ or \LaTeX\ control sequence inside a special character,
-but it {\em will\/} process other characters.
-Thus a style that converts all titles to lower case
-would convert
-\begin{verbatim}
- The {\TeX BOOK\NOOP} Experience
-\end{verbatim}
-to
-\begin{verbatim}
- The {\TeX book\NOOP} experience
-\end{verbatim}
-(the `{\tt The}' is still capitalized
-because it's the first word of the title).
-
-This special-character scheme is useful for handling accented characters,
-for getting \BibTeX's alphabetizing to do what you want,
-and, since \BibTeX\ counts an entire special character as just one letter,
-for stuffing extra characters inside labels.
-The file \hbox{\tt XAMPL.BIB} distributed with \BibTeX\
-gives examples of all three uses.
-
-\item
-This final item of the section describes \BibTeX's names
-(which appear in the \hbox{\tt author} or \hbox{\tt editor} field)
-in slightly more detail than what
-appears in Appendix~B of the \LaTeX\ book.
-In what follows, a ``name'' corresponds to a person.
-(Recall that you separate multiple names in a single field
-with the word ``and''$\!$, surrounded by spaces,
-and not enclosed in braces.
-This item concerns itself with the structure of a single name.)
-
-Each name consists of four parts: First, von, Last, and~Jr;
-each part consists of a (possibly empty) list of name-tokens.
-The Last part will be nonempty if any part is,
-so if there's just one token, it's always a Last token.
-
-Recall that Per Brinch~Hansen's name should be typed
-\begin{verbatim}
- "Brinch Hansen, Per"
-\end{verbatim}
-The First part of his name has the single token ``Per'';
-the Last part has two tokens, ``Brinch'' and ``Hansen'';
-and the von and Jr parts are empty.
-If you had typed
-\begin{verbatim}
- "Per Brinch Hansen"
-\end{verbatim}
-instead, \BibTeX\ would (erroneously) think ``Brinch'' were a First-part token,
-just as ``Paul'' is a First-part token in ``John~Paul Jones''$\!$,
-so this erroneous form would have two First tokens and one Last token.
-
-Here's another example:
-\begin{verbatim}
- "Charles Louis Xavier Joseph de la Vall{\'e}e Poussin"
-\end{verbatim}
-This name has four tokens in the First part, two in the von, and
-two in the Last.
-Here \BibTeX\ knows where one part ends and the other begins because
-the tokens in the von part begin with lower-case letters.
-
-In general, it's a von token if the first letter at brace-level~0
-is in lower case.
-Since technically everything
-in a ``special character'' is at brace-level~0,
-you can trick \BibTeX\ into thinking that
-a token is or is not a von token by prepending a dummy
-special character whose first letter past the \TeX\ control sequence
-is in the desired case, upper or lower.
-
-To summarize, \BibTeX\ allows three possible forms for the name:
-\begin{verbatim}
- "First von Last"
- "von Last, First"
- "von Last, Jr, First"
-\end{verbatim}
-You may almost always use the first form;
-you shouldn't if either there's a Jr part,
-or the Last part has multiple tokens but there's no von part.
-
-\end{enumerate}

-@cindex hyperlink drivers
-@cindex drivers, hyperlink
-The original @TeX{} engine has no built-in support for hyperlinks.
-Many of the present-day file formats with hyperlinking capabilities
-did not even exist at the time @TeX{} was written. However, @TeX{}'s
-@findex special
-@code{\special} primitive can be used to instruct @TeX{} to write
-special directives into its @file{.dvi} output file. These directives
-are not interpreted by @TeX{} in any way; they are intended for programs
-which process the @file{.dvi} files produced by @TeX{}, be it printing
-or converting to other formats, such as
-@pindex .ps @r{files}
-@pindex .pdf @r{files}
-@file{.ps} or @file{.pdf}.
-
-Another approach is to extend the original @TeX{} engine with the
-ability to generate one of the hyperlinking formats; @TeX{}'s set of
-primitives can be extended to include hyperlink commands. This is the
-approach used by the pdf@TeX{} engine, which is capable of producing
-@file{.pdf} files directly from the @TeX{} source, skipping the
-@file{.dvi} generation and processing step.
-
-It turns out that the sets of commands for different formats are mostly
-not interchangeable, as each of the file formats has its own quirks and
-capabilities. And this is where Eplain @dfn{hyperlink drivers} come
-into play.
-
-In order for Eplain to generate proper commands, Eplain has to know
-two things: which engine or @file{.dvi} processor you are using, and
-the set of commands it understands.
-
-The knowledge about the commands that the various processors
-understand is programmed into Eplain's hyperlink drivers. Eplain
-provides two drivers, @code{pdftex} and @code{dvipdfm}, named after
-the programs which process the hyperlink commands,
-@pindex pdftex
-pdf@TeX{} and
-@pindex dvipdfm
-dvipdfm. Therefore, Eplain can only produce hyperlink commands for one
-of these two programs---except that the extended @code{dvipdfmx} program
-can be used as well as the original @code{dvipdfm}, since they are
-compatible.
-
-To tell Eplain which @file{.dvi} processor or extended @TeX{} engine you
-are using, use the command
-@findex enablehyperlinks
-@code{\enablehyperlinks}.
-
-For example:
-
-@example
-\enablehyperlinks
-@end example
-
-@noindent instructs Eplain to attempt to automatically detect which
-driver to use, as follows: if it detects pdf@TeX{} in PDF mode, it
-loads the @code{pdftex} driver. If it does not detect pdf@TeX{} in
-PDF mode, the @code{dvipdfm} driver is loaded. The detection is based
-on the
-@findex ifpdf
-@code{\ifpdf} switch (@pxref{Checking for PDF output}).
-
-If necessary, you can explicitly specify the driver name:
-
-@example
-\enablehyperlinks[pdftex]
-@end example
-
-@noindent will start producing hyperlinks under the assumption that
-you are using pdf@TeX{}.
-
-Eplain does not produce any hyperlinks until you explicitly enable
-them with @code{\enablehyperlinks}. For one thing, this keeps Eplain
-backward-compatible with previous releases without hyperlink support.
-For another, you may be using a program other than pdf@TeX{} or
-@code{dvipdfm}, which does not understand their hyperlink commands.
-
-@subheading Concepts and Terminology
-
-In general, hyperlinks work as follows. You mark some place in your
-document as a hyperlink destination, associating a @dfn{hyperlink
-label} with that destination. Next, somewhere within your document,
-you create a hyperlink, using a label to identify the destination you
-want this link to point to. A hyperlink is a region in the document
-(which can take many forms, for example, text or a picture); when a
-user clicks on that region, they will be taken to a place in the
-document marked by the corresponding destination. The following two
-sections (@ref{Explicit hyperlinks}, and @ref{Implicit hyperlinks})
-describe the macros you can use to define destinations and create
-links pointing to those destinations.
-
-In the rest of this chapter, we will often need to refer to links and
-destinations jointly, in which case we will use the term
-@dfn{hyperlinks}. We will use the terms @dfn{links} and
-@dfn{destinations} in cases when we need to refer specifically to
-links or destinations.
-
-@cindex link type
-@cindex destination type
-@cindex type, link and destination
-Hyperlink drivers provide several kinds of links and destinations. We
-will refer to them as @dfn{link types} and @dfn{destination types}.
-
-For example, one of the destination types that the @code{pdftex}
-driver provides is the @samp{xyz} type; when the user follows a link
-pointing to an @samp{xyz} destination, the exact location marked by
-that destination is displayed. Another destination type provided by
-the @code{pdftex} driver is the @samp{fit} type; when the user follows
-a link pointing to a @samp{fit} destination, the page containing that
-destination is zoomed to fit into the window in which the document is
-displayed.
-
-Similarly, drivers support various link types. For example, with the
-@code{pdftex} driver, the usual link type used to refer to
-destinations in the current document is called @samp{name}. You can
-also create a link pointing to another local document (by using the
-@samp{filename} link type) or to a URL (by using the @samp{url} link
-type).
-
-@cindex link options
-@cindex destination options
-@cindex options, link and destination
-In addition, each hyperlink driver supports a number of destination and
-link @dfn{options}. By setting these options you can customize
-hyperlink parameters (e.g., the thickness of the border drawn around a
-hyperlink) or pass information to hyperlinks (for example, file name of
-a document, for a link pointing to a destination in another document).
-
-@xref{Hyperlink drivers}, for the description of hyperlink types and
-options supported by the drivers. @xref{Setting hyperlink types and
-options}, for the information on how to set hyperlink options.

-@node Explicit hyperlinks
-@section Explicit hyperlinks
-
-@cindex explicit hyperlinks
-@cindex hyperlinks, explicit
-@findex hldest
-Explicit hyperlinks are created by you, in the source of your
-document. The simplest command is @code{\hldest}, which marks the
-current position in your document as a destination:
-
-@example
-\hldest@{@var{type}@}@{@var{options}@}@{@var{label}@}
-@end example
-
-@noindent Here @var{type} is one of the destination types supported by
-the hyperlink driver (@pxref{Hyperlink drivers}), @var{options} is a
-comma-separated list of option assignments, and @var{label} is the
-hyperlink label to associate with this destination. This label will
-identify the destination when creating links pointing to this
-destination. For example, with the @code{pdftex} driver, the command
-
-@example
-\hldest@{xyz@}@{zoom=2000@}@{index@}
-@end example
-
-@noindent creates a destination of type @samp{xyz} (``the current
-position''), sets the magnification ratio for this destination to be
-200%, and associates the label @code{index} with the destination.
-
-@findex hlstart
-@findex hlend
-Another command, @code{\hlstart}, paired with @code{\hlend}, turns all
-intervening material into a link:
-
-@example
-\hlstart@{@var{type}@}@{@var{options}@}@{@var{label}@} @dots{} \hlend
-@end example
-
-@noindent Here @var{type}, @var{options} and @var{label} have the same
-meaning as for @code{\hldest}. Continuing the previous example,
-
-@example
-\hlstart@{name@}@{bstyle=U,bwidth=2@}@{index@} Index\hlend
-@end example
-
-@noindent typesets the word `Index' as a link with underline border of
-width@tie{}2@tie{}PostScript points, pointing to the named destination
-@code{index} defined in the previous example. (The other options, like
-highlight mode and border color, are determined by the defaults,
-@pxref{Setting default types and options}).
-
-Both @code{\hldest} and @code{\hlstart} ignore following spaces.
-
-Both @code{\hldest} and @code{\hlstart} expand the first token of
-@var{options} once, so you can save a list of options in a macro and
-pass it for the @var{options}. For example:
-
-@example
-\def\linkopts@{bstyle=U,bwidth=2@}
-\hlstart@{name@}@{\linkopts@}@{index@}Index\hlend
-@end example
-
-@noindent is functionally equivalent to the previous example.

-@node Implicit hyperlinks
-@section Implicit hyperlinks
-
-@cindex implicit hyperlinks
-@cindex hyperlinks, implicit
-@dfn{Implicit hyperlinks} are hyperlinks created implicitly by various
-Eplain macros, such as the macros for citations, cross-references,
-indexing, etc.
-
-@cindex link group
-@cindex linkgroup
-@cindex group, link
-@cindex destination group
-@cindex destgroup
-@cindex group, destination
-All such macros are divided into @dfn{link groups} and
-@dfn{destination groups} (or @dfn{linkgroups} and @dfn{destgroups} for
-short) so that parameters can be set individually for each group. For
-example, all equation macros which define a destination are assigned
-to the `eq' destgroup; equation macros which create a link are
-assigned to the `eq' linkgroup. By setting parameters for the `eq'
-linkgroup (destgroup), you can uniformly customize all links
-(destinations) related to equation references, without interfering
-with settings for the other groups.
-
-@xref{Setting hyperlink types and options}, for information on how to
-set parameters for a group.
-
-Here is the list of the linkgroups:
-

-@code{\url} command from the @LaTeX{} package
-@pindex url.sty
-@file{url} (@pxref{Packages known to work}), as well as any new
-@code{\url}-like commands you define. The type for this linkgroup is
-set to @samp{url} by the drivers which support this link type.
-@samp{url} links use the parameter to the @code{\url} command as the URL
-to point to.
-
-You may be using the @code{\url} command to typeset something other than
-a URL, e.g., a path, for which you do not want a link to be created; in

-produced by the @code{\bibliography} command.
-
-@cindex bibliography, hyperlinks
-@cindex hyperlinks, bibliography
-@cindex group `bib'
-@cindex destgroup `bib'
-@findex bibliography @r{(hyperlinks)}
-The `bib' destgroup includes the macros related to the

-
-@findex definexref @r{(hyperlinks)}
-@cindex cross-references, hyperlinks
-@cindex hyperlinks, cross-references
-@cindex group `definexref'
-@cindex destgroup `definexref'
-The `definexref' destgroup is for the @code{\definexref} command
-(@pxref{Defining generic references}). @code{\definexref} defines a
-destination using the cross-reference label (the first argument) as the
-hyperlink label.
-
-@cindex group `ref'
-@cindex linkgroup `ref'
-The `ref' linkgroup includes @code{\refn} and @code{\xrefn} (they are
-synonyms), @code{\ref}, and @code{\refs} (@pxref{Using generic
-references}).
-
-@findex refn @r{(hyperlinks)}
-@findex xrefn @r{(hyperlinks)}
-@code{\refn} turns the cross-reference it produces into a link, using
-the cross-reference label as the hyperlink label. If an optional
-argument is present, it is tied by
-@findex reftie
-@code{\reftie} to the reference and become part of the link.
-
-@findex ref @r{(hyperlinks)}
-@code{\ref} works similarly to @code{\refn}. It takes an optional
-argument, which is treated the same way as the optional argument to
-@code{\refn}. In addition, @code{\ref} can produce a ``class word''.
-Both the optional argument and the class word become part of the link,
-when present. The cross-reference is tied by
-@findex reftie
-@code{\reftie} to the preceding word. The optional argument is
-separated from the class word by
-@findex refspace
-@code{\refspace}.
-
-@findex refs @r{(hyperlinks)}
-Unlike @code{\ref}, @code{\refs} does not take an optional argument and
-does not make the class word part of the link, which is appropriate for
-its intended use.

-
-@findex xref @r{(hyperlinks)}
-@findex refspace
-@findex xrefpageword
-@cindex group `xref'
-@cindex linkgroup `xref'

-All commands that define equation labels are part of the `eq' destgroup.
-These are @code{\eqdef}, @code{\eqdefn}, @code{\eqsubdef} and
-@code{\eqsubdefn} (@pxref{Equation references}). All these commands use
-the equation label as the hyperlink label. However, if the equation
-label is empty, they make up a (hopefully) unique hyperlink label for
-the destination. This label will be used for the link when you refer to
-this empty-labeled equation with one of the equation reference macros.
-
-@findex phantomeqlabel
-@findex phantomeqnumber
-The command @code{\phantomeqlabel} is called to generate hyperlink
-labels for the empty-labeled equations. By default, it produces the
-labels in the format @samp{PHEQ@var{number}}, where @var{number} comes
-from the count register @code{\phantomeqnumber}; this count register is
-incremented at every empty-labeled equation definition.
-

-@findex reftie
-@cindex group `eq'
-@cindex linkgroup `eq'
-The commands @code{\eqref} and @code{\eqrefn} (@pxref{Equation
-references}) form the `eq' linkgroup. These commands take an optional
-argument, which, when present, is tied with @code{\reftie} to the
-equation reference and becomes part of the link. The equation label is
-used for the hyperlink label; if the label is empty, the link is for the
-label generated for the last empty-labeled equation.

-@cindex destgroup `idx'
-All indexing commands (@code{\idx}, @code{\idxname}, @code{\idxmarked},

-commands}) form the `idx' destgroup. The `idx' linkgroup consists of
-the macros which are used to typeset the index when you say
-@findex readindexfile @r{(hyperlinks)}
-@code{\readindexfile@{@var{index-letter}@}} (@pxref{Typesetting an
-index}).
-
-@pindex makeindex
-To create the links in index entries, Eplain uses MakeIndex's
-``encapsulation'' feature. When you use an indexing macro to mark an
-index term, Eplain writes out a line to the
-@pindex .idx @r{files}
-@file{.idx} file of the following general form:
-
-@example
-\indexentry@{@var{entry}|@var{pagemarkup}@}@{@var{pageno}@}
-@end example
-
-@noindent where @var{entry} is the index entry (converted into the
-internal format that MakeIndex understands), @var{cs} is the markup
-command you specified with the @code{pagemarkup=@var{cs}} optional
-argument to the indexing commands (@pxref{Modifying index entries}),
-and @var{pageno} is the page number on which the term appeared. When
-processing the @file{.idx} file, MakeIndex makes the page number an
-argument to the page markup command (``encapsulates'' the page
-number), so the page number in the
-@pindex .ind @r{files}
-@file{.ind} file appears as @code{\@var{cs}@{@var{pageno}@}}. Eplain
-internally replaces the @var{cs} command name with its own command,
-which, in addition to calling the original @code{\@var{cs}}
-encapsulator, turns the page number into a link.
-
-Eplain provides two approaches to linking page numbers in the index to
-locations of index terms in the text.

-
-@node Exact destinations for index terms
-@subsubsection Exact destinations for index terms
-
-In this approach, each command that marks an index term defines a unique
-destination and passes its label on to the @file{.idx} file as part of
-the @code{\indexentry} command. The @code{\indexentry} line that Eplain
-writes to the @file{.idx} file becomes
-
-@example
-\indexentry@{@var{entry}|hlidx@{@var{label}@}@{@var{cs}@}@}@{@var{pageno@}}
-@end example
-
-@findex hlidx
-@noindent where @code{\hlidx} is the command that is defined by Eplain
-to take three arguments: a hyperlink label (@var{label}), a name of
-page number encapsulator (@var{cs}) and a page number (@var{pageno}).
-In the @file{.ind} file that MakeIndex will generate, the page number
-will now appear as
-
-@example
-\hlidx@{@var{label}@}@{@var{cs}@}@{@var{pageno}@}
-@end example
-
-@noindent The result of this command is
-@code{\@var{cs}@{@var{pageno}@}}, wrapped up into a link pointing to
-@var{label} destination.
-
-The hyperlink labels for the index terms are generated by the
-@findex hlidxlabel
-@code{\hlidxlabel} command, by default in the format
-@samp{IDX@var{number}}, where @var{number} is the value of the count
-register
-@findex hlidxlabelnumber
-@code{\hlidxlabelnumber}. This count register is incremented at each
-index term.
-
-@cindex exact index hyperlinks
-@cindex index, exact hyperlinks
-@cindex hyperlinks, index, exact
-The advantage of this approach, as compared to the second approach
-described below, is that links in the index point to exact locations of
-the indexed terms on the page. The disadvantage of this approach is
-that MakeIndex will regard @emph{all} index entries as distinct, because
-each one contains a (unique) hyperlink label. This disadvantage can be
-partially overcome by the script
-@pindex idxuniq
-@cindex filtering index entries with hyperlinks
-@cindex hyperlinks, filtering index entries
-@file{idxuniq} distributed with Eplain in the @file{util} directory.
-This script filters out @code{\indexentry} lines differing only in the
-hyperlink label but identical otherwise. You should process the
-@file{.idx} with this script before passing it on to MakeIndex. For
-example:
-
-@example
-prompt$ ./idxuniq file.idx | makeindex > file.ind
-@end example
-
-@noindent Still, this solution is not ideal, as the page-range formation
-ability of MakeIndex will not work, and there will be problems of
-apparently identical index entries clashing (e.g., when a range-end
-entry appears on the same page as another entry with the same
-definition; @file{idxuniq} will not filter out the second entry).
-
-
-@node Page destinations for index terms
-@subsubsection Page destinations for index terms
-
-In the second approach, Eplain does not write out any destination labels
-for the index terms. Instead, Eplain writes out a wrapper for page
-number encapsulator which can parse the page number and generate a link
-pointing to the @emph{page} on which the term appeared. On top of each
-page containing an index term, Eplain defines a destination with label
-produced by
-@findex hlidxpagelabel
-@code{\hlidxpagelabel}. The @code{\hlidxpagelabel} command takes a
-single argument (page number @var{number}) and by default produces the
-label in the format @samp{IDXPG@var{number}}.
-
-With this approach, the @code{\indexentry} line which Eplain writes to
-the @code{.idx} file looks like this:
-
-@example
-\indexentry@{@var{entry}|hlidxpage@{@var{cs}@}@}@{@var{pageno@}}
-@end example
-
-@findex hlidxpage
-@noindent where @code{\hlidxpage} is the command that is defined by Eplain
-to take two arguments: a name of page number encapsulator (@var{cs})
-and a page number (@var{pageno}). In the @file{.ind} file that
-MakeIndex will generate, the page number will appear as
-
-@example
-\hlidxpage@{@var{cs}@}@{@var{pageno}@}
-@end example
-
-The advantage of this approach is that all features of MakeIndex are
-intact. The drawback is that links in the index do not point to exact
-locations of indexed terms on a page, but to the top of a page on
-which the term appears.
-
-@cindex index, parsing page numbers
-@cindex page range, parsing
-@cindex page list, parsing
-@cindex parsing page numbers
-Another disadvantage is that this approach depends on the page range and
-page list separators which MakeIndex was configured to output.
-@code{\hlidxpage} must be able to parse the first page number in a page
-range like @samp{1--4}. In addition, page list parsing is needed
-because MakeIndex combines two consecutive page numbers in one call to
-the page number encapsulator, so @code{\hlidxpage} can be passed, e.g.,
-@samp{1, 2} for the @var{pageno}. In this last case, @code{\hlidxpage}
-splits the two page numbers, applies @code{\@var{cs}} to each of them,
-and makes each of the page numbers a link to the appropriate page. Note
-that this will alter typesetting slightly, because now the page list
-separator (a comma followed by a space, by default) is not typeset using
-the page number encapsulator (@code{\@var{cs}}).
-
-Eplain's defaults for the page list and page number delimiters are the
-same as those in MakeIndex, a comma followed by a space (@samp{, }) and
-two dashes (@samp{--}), respectively. If you customize MakeIndex to use
-different delimiters, you must not forget to let Eplain know about them
-with the commands
-
-@example
-\setidxpagelistdelimiter@{@var{list-delim}@}
-\setidxpagerangedelimiter@{@var{page-delim}@}
-@end example

-The approach that Eplain should use for the index terms can be

-a comma-separated list of options. The
-@findex idxexact

-@code{idxpage} the second, and
-@findex idxnone
-@code{idxnone} disables hyperlink support for the index terms

-@cindex raising hyperlink destinations
-@cindex hyperlink destination, raising
-@cindex destinations, raising
-Specifies how much to raise destinations above the baseline. When set
-to zero or empty, destinations are placed at the baseline.
-
-It is usually convenient to set this option to some variable parameter,
-so that the height to which destinations are raised is automatically
-adjusted according to the current context. For example, setting it to
-@findex normalbaselineskip
-@code{\normalbaselineskip} (or some fraction of it, like
-@code{1.7\normalbaselineskip}) makes the setting appropriate for
-different point sizes, in case your document uses more than one.
-
-The default setting is @code{\normalbaselineskip}. Initially, the
-destgroups do not define this option, so they fall back on the default,
-except for the `eq' destgroup, for which this option is set to
-@code{1.7\normalbaselineskip},
-@cindex mathematics displays, hyperlinks
-@cindex displayed math and hyperlinks
-@cindex large operators and hyperlinks
-@cindex hyperlinks, large operators
-@cindex destinations, large operators
-to accommodate the usual cases of large operators in displayed math.

-@item colormodel
-@itemx color
-@findex colormodel @r{(hyperlink option)}
-@findex color @r{(hyperlink option)}
-@cindex color, hyperlinks
-These two options define the color to be used for rendering the link
-text. The colors are used only when a @code{\color} command is defined,
-e.g., by loading the @LaTeX{} `color' package (@pxref{Packages known to
-work}). The @code{\color} command is called as
-@code{\color[@var{colormodel}]@{@var{color}@}}, where @var{colormodel}
-and @var{color} are the definitions of the @code{colormodel} and
-@code{color} options, respectively. However, if @var{colormodel} is
-empty, the optional argument to @code{\color} is omitted; and if
-@var{color} is empty, the @code{\color} command is omitted altogether.
-The default setting is @code{@var{colormodel}=cmyk} and
-@code{@var{color}=0.28,1,1,0.35}.
-
-When specifying colors with several components delimited by commas
-(e.g., RGB and CMYK colors in the @LaTeX{} `color' package), it is not
-possible to specify the components directly in the option list of
-@code{\hlopts}, because comma is the option list delimiter. With the
-`color' package, it is possible to specify such colors by defining a
-custom color with @code{\definecolor} and using the new color name with
-an empty @var{colormodel} (see examples below).
-
-Examples:
-@example
-\hlopts@{colormodel=,color=blue@}% predefined color
-\definecolor@{mycolor@}@{rgb@}@{.3,.8,.95@}
-\hlopts@{colormodel=,color=mycolor@}% custom color
-\hlopts@{colormodel=gray,color=.4@}

-Select this driver to suppress all hyperlinks in your document.
-
-Selecting this driver is quite different from not selecting any driver
-at all, or from selecting some driver and then turning hyperlinks off
-for the entire document with
-@findex hloff
-@code{\hloff} and
-@findex hldestoff
-@code{\hldestoff} (@pxref{Turning hyperlinks on/off}).
-
-The purpose of @code{\hldestoff} and @code{\hloff} is to mark (parts) of
-your document where hyperlinks should never appear. (Imagine you want
-to prevent a cross-referencing macro from generating a link at a certain
-spot in your document.)
-
-If instead you have prepared a document with hyperlinks and just want to
-compile a version without them, it is better to select the driver
-@code{nolinks}. This ensures that spacing and page-breaking are the
-same as what you were getting with hyperlinks enabled.
-
-The reason for this is that hyperlinks are produced by the
-@code{\special} primitives or low-level hyperlink commands. Each such
-command is placed inside a
-@cindex whatsits, made by hyperlinks
-@dfn{whatsit} (an internal @TeX{} object), which may introduce
-legitimate breakpoints at places where none would exist without the
-whatsits. The macros @code{\hldestoff} and @code{\hloff} disable the
-hyperlink macros completely, so that no whatsits are produced.
-
-In contrast, the @code{nolinks} driver does not completely disable
-hyperlink macros. Instead, it defines them to merely write to the log
-file (what gets written is unimportant). This also produces
-whatsits, thus imitating the whatsits from the hyperlink commands.
-(This trick was borrowed from the
-@pindex color.sty
-@cindex graphics collection, @LaTeX{}
-@cindex @LaTeX{} graphics collection
-@LaTeX{} `color' package.)
-
-Another reason for using @code{nolinks} is that in horizontal mode
-@code{\hldest} places destinations inside boxes of zero width, height,
-and depth. When you say @code{\hldestoff}, @code{\hldest} will omit
-both destination definitions and these boxes. The missing boxes can
-again cause the typesetting to be inconsistent with that with
-destinations enabled. Here again, the @code{nolinks} driver helps by
-defining @code{\hldest} to produce the empty boxes.

-`eq' destgroup, because the formulas often contain large parentheses and
-brackets. But when doing so, you want to leave the other settings

-
-@example
-$$\hldestopts[eq]@{raise=2.5\normalbaselineskip@}

-list contains one setting:
-

-The simplest way to install Eplain is simply to install the file

-installation. I personally install @file{eplain.tex} in

-source file with @code{\input}. You do this by issuing a sequence of

-
-@example

-prompt$ initex
-This is TeX, ...

-@cindex undefined labels, warnings about
-@noindent You must make sure that @file{eplain.aux} exists @emph{before} you
-run @file{initex}; otherwise, warning messages about undefined labels
-will never be issued.
-
-You then have to install the resulting @file{eplain.fmt} in some system
-directory or set an environment variable to tell @TeX{} how to find it.
-I install the format files in @file{/usr/local/lib/texmf/ini}; the
-environment variable for the Web2C port of @TeX{} to Unix is
-@code{TEXFORMATS}.
-
-Some implementations of @TeX{} (including Web2C) use the name by which
-@TeX{} is invoked to determine what format to read. For them, you
-should make a link to the @file{virtex} program named @file{etex}, and
-then install the format file with the name @file{etex.fmt}. This lets
-users invoke @TeX{} as @file{etex} and get the format file read
-automatically, without having to say @samp{&eplain}.
-
-For convenience, the file @file{etex.tex} in the distribution directory
-does @code{\input eplain} and then @code{\dump}, so that if you replace
-@samp{eplain} with @samp{etex} in the example above, the format file
-will end up with the right name.

-@node Introduction
-@chapter Introduction
-
-@cindex Eplain, purpose of
-
-@pindex xeplain.tex
-The @dfn{Eplain} macro package expands on and extends the definitions in
-plain @TeX{}. This manual describes the definitions that you, as either
-an author or a macro writer, might like to use. It doesn't discuss the
-implementation; see comments in the source code (@file{xeplain.tex}) for
-that.
-
-Eplain is not intended to provide ``generic'' typesetting capabilities, as
-do @LaTeX{} (written by Leslie Lamport)
-@cindex @LaTeX{}
-@cindex Lamport, Leslie
-or Texinfo
-@cindex Texinfo
-(written by Richard Stallman and others).
-@cindex Stallman, Richard
-@cindex rms
-Instead, it provides definitions that are intended to be useful
-regardless of the high-level commands that you use when you actually
-prepare your manuscript.
-
-For example, Eplain does not have a command @code{\section}, which
-would format section headings in an ``appropriate'' way, such as
-@LaTeX{}'s @code{\section}. The philosophy of Eplain is
-that some people will always need or want to go beyond the macro
-designer's idea of ``appropriate''. Such canned macros are
-fine---as long as you are willing to accept the resulting output. If
-you don't like the results, or if you are trying to match a different
-format, you are out of luck.
-
-On the other hand, almost everyone would like capabilities such as
-cross-referencing by labels, so that you don't have to put actual page
-numbers in the manuscript. The author of Eplain
-@cindex Berry, Karl
-is not aware of any generally available macro packages that (1)@tie{}do
-not force their typographic style on an author, and yet (2)@tie{}provide
-such capabilities.
-
-Besides such generic macros as cross-referencing, Eplain
-contains another set of definitions: ones that change the conventions of
-plain @TeX{}'s output. For example, math displays in @TeX{} are, by
-default, centered. If you want your displays to come out
-left-justified, you have to plow through @cite{The @TeX{}book} to find
-some way to do it, and then adapt the code to your own needs. Eplain
-tries to take care of the messy details of such things, while still
-leaving the detailed appearance of the output up to you.
-
-Finally, numerous definitions turned out to be useful as Eplain was
-developed. They are also documented in this manual, on the chance that
-people writing other macros will be able to use them.
-
-You can send bug reports or suggestions to
-@email{tex-eplain@@tug.org}. The current version number of Eplain is
-defined as the macro @code{\fmtversion}
-@cindex version number
-@findex fmtversion
-at the end of the source file @file{eplain.tex}. When corresponding,
-please refer to it.

-@chapter Invoking Eplain
-
-@cindex Eplain, invoking
-The simplest way to use Eplain is simply to put:
-
-@example
-\input eplain
-@end example
-
-@noindent at the beginning of your input file. The macro file is small
-enough that reading it does not take an unbearably long time---at least on
-contemporary machines.
-
-In addition, if a format (@file{.fmt})
-@pindex .fmt @r{file}
-file has been created for Eplain (see the previous section), you can
-eliminate the time spent reading the macro source file. You do this
-by responding @code{&eplain} to @TeX{}'s @samp{**} prompt. For
-example:
-
-@example
-initex
-This is TeX, ...
-**&eplain myfile
-@end example
-
-Depending on the implementation of @TeX{} which you are using, you might
-also be able to invoke @TeX{} as @file{eplain} and have the format file
-automatically read.
-
-If you write something which you will be distributing to others, you
-won't know if the Eplain format will be loaded already. If it is, then
-doing @code{\input eplain} will waste time; if it isn't, then you must
-load it. To solve this, Eplain defines the control sequence
-@code{\eplain}
-@findex eplain
-to be the letter @code{t} (a convention borrowed from Lisp; it doesn't
-actually matter what the definition is, only that the definition
-exists). Therefore, you can do the following:
-@example
-\ifx\eplain\undefined \input eplain \fi
-@end example
-@noindent where @code{\undefined} must never acquire a definition.
-
-Eplain consists of several source files:
-@table @file
-@item xeplain.tex
-most of the macros;
-
-@item arrow.tex
-commutative diagram macros (@pxref{Arrow theoretic diagrams}), written by
-Steven Smith;
-
-@item btxmac.tex
-bibliography-related macros (@pxref{Citations});
-
-@item ifpdf.sty
-sets the switch @code{\ifpdf}, which can be used to
-detect pdf@TeX{} in PDF mode (@pxref{Checking for PDF output}), written
-by Heiko Oberdiek;
-
-@item path.sty
-macro for allowing line breaks at punctuation characters within long
-pathnames, electronic mail addresses, etc., (@pxref{Paths}), written
-by Philip Taylor;
-
-@item texnames.sty
-abbreviations for various @TeX{}-related names (@pxref{Logos}), edited
-by Nelson Beebe.
-
-@end table
-
-@noindent The file @file{eplain.tex} is all of these files merged
-together, with comments removed.
-
-All of these files except @file{xeplain.tex} can be input individually,
-if all you want are the definitions in that file.
-
-Also, since the bibliography macros are fairly extensive, you might not
-want to load them, to conserve @TeX{}'s memory. Therefore, if the
-control sequence @code{\nobibtex}
-@findex nobibtex
-is defined, then the bibliography definitions are skipped. You must set
-@code{\nobibtex} before @file{eplain.tex} is read, naturally. For
-example, you could start your input file like this:
-
-@example
-\let\nobibtex = t
-\input eplain
-@end example
-
-By default, @code{\nobibtex} is undefined, and so the bibliography
-definitions @emph{are} made.
-
-@findex noarrow
-Likewise, define @code{\noarrow} if you don't want to include the
-commutative diagram macros from @file{arrow.tex}, perhaps because you
-already have conflicting ones.
-
-If you don't want to read or write an @file{aux} file at all, for any
-kind of cross-referencing, define @code{\noauxfile}
-@findex noauxfile
-before reading @file{eplain.tex}. This also turns off all warnings
-about undefined labels.
-
-@pindex amsppt.sty
-@cindex AMS@TeX{} conflicts
-Eplain conflicts with AMS@TeX{} (to be precise, with @file{amsppt.sty}):
-the macros @code{\cite} and @code{\ref} are defined by both.
-
-If you want to use AMS@TeX{}'s @code{\cite}, the solution is to define
-@code{\nobibtex} before reading Eplain, as described above.
-
-If you have @file{amsppt.sty} loaded and use @code{\ref}, Eplain writes
-a warning on your terminal. If you want to use the AMS@TeX{}
-@code{\ref}, do @code{\let\ref = \amsref} after reading Eplain.
-To avoid the warning, do @code{\let\ref = \eplainref} after reading
-Eplain and before using @code{\ref}.
-
-@pindex texi2dvi
-@pindex bibtex
-@pindex makeindex
-Sometimes you may need to run @TeX{} more then once on your
-@file{.tex} file in order to produce and typeset indexes, resolve
-undefined cross-references and/or citations. The shell script
-@command{texi2dvi} from the Texinfo documentation system (see
-@url{http://www.gnu.org/software/texinfo/}) can automate this process:
-it runs Bib@TeX{}, MakeIndex and @TeX{} as many times as needed to
-complete the compilation process. You will need to set the
-@env{LATEX} environment variable to @samp{tex}. For example, in a
-Bourne-compatible shell, the following command will do all the work:
-
-@example
-prompt$ LATEX=tex texi2dvi file.tex
-@end example
-
-@pindex pdftex
-@noindent (Despite the name, @command{texi2dvi} can also produce
-@file{.pdf} files; just set @samp{LATEX=pdftex}.) See the output from
-the command @command{texi2dvi --help} for invoking information and a
-full list of options.

-@node Category codes
-@section Category codes
-
-@cindex category codes
-
-Plain @TeX{} defines @code{\active} (as the number 13) for use in
-changing category codes. Although the author of @cite{The @TeX{}book}
-@cindex Knuth, Donald Ervin
-has ``intentionally kept the category codes numeric'', two other
-categories are commonly used: letters (category code 11) and others
-(12). Therefore, Eplain defines @code{\letter} and
-@code{\other}.
-@findex letter
-@findex other
-
-Sometimes it is cleaner to make a character active without actually
-@cindex active characters
-writing a @code{\catcode} command. The @code{\makeactive} command takes
-@findex catcode
-@findex makeactive
-a character as an argument to make active (and ignores following
-spaces). For example, here are two commands which both make @kbd{\}
-active:
-@cindex backslash character
-
-@example
-\makeactive`\\ \makeactive92
-@end example
-
-@cindex user-inaccessible macros
-@cindex inaccessible macros
-Sometimes you might want to temporarily change the category code of
-the `@@' character to @code{\letter}, so that you can use or define
-macros which are normally inaccessible to the user. For such
-situations, Eplain provides the @code{\makeatletter}
-@findex makeatletter
-command. It sets the category code of `@@' to @code{\letter} (11) and
-defines
-@code{\resetatcatcode}
-@findex resetatcatcode
-to restore the category code to whatever it was before the call to
-@code{\makeatletter}. For example:
-
-@example
-\makeatletter
-\def\@@hidden@@macro@{This macro cannot normally be
- called / redefined by the user@}
-\resetatcatcode
-@end example
-
-@noindent There is also @code{\makeatother}
-@findex makeatother
-which works similarly but sets the category code of `@@' to
-@code{\other} (12).
-
-Usually, when you give a definition to an active character, you have
-to do so inside a group where you temporarily make the character active,
-and then give it a global definition (cf.@: the definition of
-@code{\obeyspaces} in @cite{The @TeX{}book}).
-@cindex definitions, global
-This is inconvenient if you are writing a long macro, or if the
-character already has a global definition you do not wish to transcend.
-Eplain provides @code{\letreturn}, which defines the usual end-of-line
-@findex letreturn
-@cindex return character
-character to be the argument. For example:
-
-@example
-\def\mymacro@{@dots{} \letreturn\myreturn @dots{} @}
-\mymacro hello
-there
-@end example
-
-@noindent The end-of-line between @samp{hello} and @samp{there} causes
-@code{\myreturn} to be expanded.
-
-@cite{The @TeX{}book} describes @code{\uncatcodespecials},
-@findex uncatcodespecials
-which makes all characters which are normally ``special'' into ``other''
-characters, but the definition never made it into plain @TeX{}.
-Eplain therefore defines it.
-
-Finally, @code{\percentchar}
-@findex percentchar
-expands into a literal `%' character. This is useful when you
-@code{\write} @TeX{} output to a file, and want to avoid spurious
-spaces. For example, Eplain writes a @code{\percentchar} after the
-definition of cross-references. The macros @code{\lbracechar}
-@findex lbracechar
-and @code{\rbracechar}
-@findex rbracechar
-expand similarly.
-
-
-@node Allocation macros
-@section Allocation macros
-
-@cindex allocation macros
-@cindex register allocation
-
-Plain @TeX{} provides macros that allocate registers of each primitive
-type in @TeX{}, to prevent different sets of macros from using the same
-register for two different things. The macros are all named starting
-with @samp{new},
-@findex new@dots{}
-e.g., @code{\newcount} allocates a new ``count''
-(integer) register. Such allocations are usually needed only at the top
-level of some macro definition file; therefore, plain @TeX{} makes the
-allocation registers @code{\outer},
-@findex outer
-to help find errors. (The error this helps to find is a missing right
-brace in some macro definition.)
-
-Sometimes, however, it is useful to allocate a register as part of
-some macro. An outer control sequence cannot be used as part of a macro
-definition (or in a few other contexts: the parameter text of a
-definition, an argument to a definition, the preamble of an alignment,
-or in conditional text that is being skipped). Therefore, Eplain
-defines ``inner'' versions of all the allocation macros, named with the
-prefix @samp{inner}:
-@code{\innernewbox},
-@findex innernewbox
-@code{\innernewcount},
-@findex innernewcount
-@code{\innernewdimen},
-@findex innernewdimen
-@code{\innernewfam},
-@findex innernewfam
-@code{\innernewhelp},
-@findex innernewhelp
-@code{\innernewif},
-@findex innernewif
-@code{\innernewinsert},
-@findex innernewinsert
-@code{\innernewlanguage},
-@findex innernewlanguage
-@code{\innernewread},@*
-@findex innernewread
-@code{\innernewskip},
-@findex innernewskip
-@code{\innernewtoks},
-@findex innernewtoks
-@code{\innernewwrite}.
-@findex innernewwrite
-
-You can also define non-outer versions of other macros in the same way
-that Eplain defines the above. The basic macro is called
-@code{\innerdef}:
-@findex innerdef
-
-@example
-\innerdef @var{\innername} @{@var{outername}@}
-@end example
-
-The first argument (@var{\innername}) to @code{\innerdef} is the
-control sequence that you want to define. Any previous definition of
-@var{\innername} is replaced. The second argument
-(@var{outername}) is the @emph{characters} in the name of the outer
-control sequence. (You can't use the actual control sequence name,
-since it's outer!)
-
-If the outer control sequence is named @var{\cs}, and you want to
-define @code{inner@var{cs}} as the inner one, you can use
-@code{\innerinnerdef},
-@findex innerinnerdef
-which is just an abbreviation for a call to @code{\innerdef}. For
-example, these two calls are equivalent:
-
-@example
-\innerdef\innerproclaim@{proclaim@}
-\innerinnerdef@{proclaim@}
-@end example
-
-
-@node Iteration
-@section Iteration
-
-@cindex iteration
-@cindex for loops
-
-You can iterate through a comma-separated list of items with
-@code{\for}.
-@findex for
-Here is an example:
-
-@example
-\for\name:=karl,kathy\do@{%
- \message@{\name@}%
-@}%
-@end example
-
-This writes @samp{karl} and @samp{kathy} to the terminal. Spaces
-before or after the commas in the list, or after the @code{:=}, are
-@emph{not} ignored.
-
-@code{\for} expands the iterated values fully (with @code{\edef}), so
-this is equivalent to the above:
-
-@example
-\def\namelist@{karl,kathy@}%
-\for\name:=\namelist\do @dots{}
-@end example
-
-
-@node Macro arguments
-@section Macro arguments
-
-@cindex arguments, ignoring
-@cindex ignoring arguments
-@cindex gobbling arguments
-It is occasionally useful to redefine a macro that takes arguments to
-do nothing. Eplain defines @code{\gobble},
-@findex gobble
-@code{\gobbletwo},
-@findex gobbletwo
-and @code{\gobblethree} to swallow one, two, and three arguments,
-respectively.
-
-For example, if you want to produce a ``short'' table of
-@cindex table of contents, short
-contents---one that includes only chapters, say---the easiest thing to
-do is read the entire @code{.toc} file (@pxref{Contents}), and just
-ignore the commands that produce section or subsection entries. To be
-specific:
-
-@example
-\let\tocchapterentry = \shorttocchapter
-\let\tocsectionentry = \gobbletwo
-\let\tocsubsectionentry = \gobbletwo
-\readtocfile
-@end example
-@noindent (Of course, this assumes you only have chapters, sections, and
-subsections in your document.)
-
-In addition, Eplain defines @code{\eattoken}
-@findex eattoken
-to swallow the single following token, using @code{\let}. Thus,
-@code{\gobble} followed by @samp{@{@dots{}@}} ignores the entire
-brace-enclosed text. @code{\eattoken} followed by the same ignores only
-the opening left brace.
-
-Eplain defines a macro @code{\identity}
-@findex identity
-which takes one argument and expands to that argument. This may be
-useful if you want to provide a function for the user to redefine, but
-don't need to do anything by default. (For example, the default
-definition of @code{\eqconstruct} (@pxref{Formatting equation
-references}) is @code{\identity}.)
-
-You may also want to read an optional argument. The established
-convention is that optional arguments are put in square brackets, so
-that is the syntax Eplain recognizes. Eplain ignores space tokens
-before an optional argument, via @code{\futurenonspacelet}.
-
-You test for an optional argument by using @code{\@@getoptionalarg}.
-@c this confuses texinfo.tex: findex @@getoptionalarg
-It takes one argument, a control sequence to expand after reading the
-argument, if present. If an optional argument is present, the control
-sequence @code{\@@optionalarg} expands to it; otherwise,
-@code{\@@optionalarg} is @code{\empty}. You must therefore have the
-category code of @kbd{@@} set to 11 (letter). Here is an example:
-
-@example
-\catcode`@@=\letter
-\def\cmd@{\@@getoptionalarg\finishcmd@}
-\def\finishcmd@{%
- \ifx\@@optionalarg\empty
- % @r{No optional argument present.}
- \else
- % @r{One was present.}
- \fi
-@}
-@end example
-
-If an optional argument contains another optional argument, the inner
-one will need to be enclosed in braces, so @TeX{} does not mistake the
-end of the first for the end of the second.
-
-
-@node Converting to characters
-@section Converting to characters
-
-@cindex characters, converting to
-Eplain defines @code{\xrlabel}
-@findex xrlabel
-to produce control sequence names for cross-reference labels, et al.
-This macro expands to its argument with an @samp{_} appended. (It does
-this because the usual use of @code{\xrlabel} is to generate a control
-sequence name, and we naturally want to avoid conflicts between control
-sequence names.)
-
-Because @code{\xrlabel} is fully expandable, to make a control
-sequence name out of the result you need only do
-@example
-@code{\csname \xrlabel@{@var{label}@}\endcsname}
-@end example
-
-@noindent The @code{\csname} primitive makes a control sequence name out
-of any sequence of character tokens, regardless of category code.
-Labels can therefore include any characters except for @samp{\},
-@samp{@{}, @samp{@}}, and @samp{#}, all of which are used in macro
-definitions themselves.
-
-@findex sanitize
-@code{\sanitize} takes a control sequence as an argument and converts
-the expansion of the control sequence into a list of character tokens.
-This is the behavior you want when writing information like chapter
-titles to an output file. For example, here is part of the definition
-of @code{\writenumberedtocentry}; @code{#2} is the title that the user
-has given.
-
-@example
-@dots{}
-\def\temp@{#2@}%
-@dots{}
- \write\tocfile@{%
- @dots{}
- \sanitize\temp

-@code{\endcsname}, thus saving some typing. The extra level of expansion
-does take some time, though, so I don't recommend it for an inner loop.
-
-@findex ece
-@code{\ece}@{@var{token}@}@{@var{name}@} abbreviates

-\expandafter @var{token} \csname @var{name} \endcsname

-
-
-@node \edefappend
-@subsection @code{\edefappend}
-
-@findex edefappend
-@code{\edefappend} is a way of adding on to an existing definition. It
-takes two arguments: the first is the control sequence name, the second
-the new tokens to append to the definition. The second argument is
-fully expanded (in the @code{\edef} that redefines the control sequence).
-
-For example:
-
-@example
-\def\foo@{abc@}
-\def\bar@{xyz@}
-\edefappend\foo@{\bar karl@}
-@end example
-
-@noindent results in @code{\foo} being defined as @samp{abcxyzkarl}.
-
-
-@node Hooks
-@subsection Hooks
-
-@cindex hooks
-A @dfn{hook} is simply a name for a group of actions which is executed
-in certain places---presumably when it is most useful to allow
-customization or modification. @TeX{} already provides many builtin
-hooks; for example, the @code{\every @dots{}} token lists are all
-examples of hooks.
-
-Eplain provides several macros for adding actions to hooks. They all
-take two arguments: the name of the hook and the new actions.
-
-@table @code
-
-@findex hookaction
-@itemx hookaction @var{name} @var{actions}
-@findex hookappend
-@itemx hookappend @var{name} @var{actions}
-@findex hookprepend
-@item hookprepend @var{name} @var{actions}
-Each of these adds @var{actions} to the hook @var{name}. (Any
-previously-defined actions are retained.) @var{name} is not a control
-sequence, but rather the characters of the name.
-
-@findex hookactiononce
-@item hookactiononce @var{name} @code{\@var{cs}}
-@code{\hookactiononce} adds @var{cs} to @var{name}, like the macros
-above, but first it adds
-
-@example
-\global\let @var{\cs} \relax
-@end example
-
-@noindent to the definition of @var{\cs}. (This implies @var{\cs} must
-be a true expandable macro, not a control sequence @code{\let} to a
-primitive or some other such thing.) Thus, @var{\cs} is expanded the
-next time the hook @var{name} is run, but it will disappear after that.
-
-The @code{\global} is useful because @code{\hookactiononce} is most
-useful when the grouping structure of the @TeX{} code could be anything.
-Neither this nor the other hook macros do global assignments to the hook
-variable itself, so @TeX{}'s usual grouping rules apply.
-@end table
-
-@findex hookrun
-The companion macro to defining hook actions is @code{\hookrun}, for
-running them. This takes a single argument, the name of the hook. If
-no actions for the hook are defined, no error ensues.
-
-Here is a skeleton of general @code{\begin} and @code{\end} macros that
-run hooks, and a couple of calls to define actions. The use of
-@code{\hookprepend} for the begin action and @code{\hookappend} for the
-end action ensures that the actions are executed in proper sequence with
-other actions (as long as the other actions use @code{\hookprepend} and
-@code{\hookappend} also).
-
-@example
-\def\begin#1@{ @dots{} \hookrun@{begin@} @dots{} @}
-\def\end#1@{ @dots{} \hookrun@{end@} @dots{} @}
-\hookprepend@{begin@}\start_underline
-\hookappend@{end@}\finish_underline
-@end example
-
-
-@node Properties
-@subsection Properties
-
-@cindex properties
-@cindex atom
-A @dfn{property} is a name/value pair associated with another symbol,
-traditionally called an @dfn{atom}. Both atom and property names are
-control sequence names.
-
-Eplain provides two macros for dealing with property lists:
-@code{\setproperty} and @code{\getproperty}.
-
-@table @code
-
-@findex setproperty
-@item \setproperty @var{atom} @var{propname} @var{value}
-@code{\setproperty} defines the property @var{property} on the atom
-@var{atom} to be @var{value}. @var{atom} and @var{propname} can be
-anything acceptable to @code{\csname}. @var{value} can be anything.
-
-@findex getproperty
-@item \getproperty @var{atom} @var{propname}
-@code{\getproperty} expands to the value stored for @var{propname} on
-@var{atom}. If @var{propname} is undefined, it expands to nothing
-(i.e., @code{\empty}).
-
-@end table
-
-The idea of properties originated in Lisp (I believe). There, the
-implementation truly does associate properties with atoms. In @TeX{},
-where we have no builtin support for properties, the association is only
-conceptual.
-
-The following example typesets @samp{xyz}.
-
-@example
-\setproperty@{a@}@{pr@}@{xyz@}
-\getproperty@{a@}@{pr@}
-@end example
-
-
-@node \expandonce
-@subsection @code{\expandonce}
-
-@cindex expansion, one-level
-@findex expandonce
-@code{\expandonce} is defined as @code{\expandafter\noexpand}. Thus,
-@code{\expandonce @var{token}} expands @var{token} once, instead of to
-@TeX{} primitives. This is most useful in an @code{\edef}.
-
-For example, the following defines @code{\temp} to be @code{\foo}, not
-@samp{abc}.
-
-@example
-\def\foo@{abc@}
-\def\bar@{\foo@}
-\edef\temp@{\expandonce\bar@}
-@end example
-
-
-@node \ifundefined
-@subsection @code{\ifundefined}
-
-@findex ifundefined
-@code{\ifundefined@{@var{cs}@} @var{t} \else @var{f} \fi} expands the
-@var{t} text if the control sequence @code{\@var{cs}} is undefined or
-has been @code{\let} to @code{\relax}, and the @var{f} text otherwise.
-
-@cindex skipping tokens
-@cindex undefined control sequence, checking for
-Since @code{\ifundefined} is not a primitive conditional, it cannot be
-used in places where @TeX{} might skip tokens ``at high speed'', e.g.,
-within another conditional---@TeX{} can't match up the @code{\if}'s and
-@code{\fi}'s.
-
-This macro was taken directly from @cite{The @TeX{}book}, page 308.
-
-
-@node \futurenonspacelet
-@subsection @code{\futurenonspacelet}
-
-@cindex lookahead without spaces
-@cindex spaces, ignoring
-@findex futurenonspacelet
-The @code{\futurelet} primitive allows you to look at the next token
-from the input. Sometimes, though, you want to look ahead ignoring any
-spaces. This is what @code{\futurenonspacelet} does. It is otherwise
-the same as @code{\futurelet}: you give it two control sequences as
-arguments, and it assigns the next nonspace token to the first, and then
-expands the second. For example:
-
-@example
-\futurenonspacelet\temp\finishup
-\def\finishup@{\ifx\temp @dots{}@}
-@end example
-
-
-@node Obeying spaces
-@section Obeying spaces
-
-@cindex whitespace
-@cindex spaces, obeying
-@cindex newlines, obeying
-@findex obeywhitespace
-
-@code{\obeywhitespace} makes both end-of-lines and space characters in
-the input be respected in the output. Unlike plain @TeX{}'s
-@code{\obeyspaces}, even spaces at the beginnings of lines turn into
-blank space.
-
-By default, the size of the space that is produced by a space
-character is the natural space of the current font, i.e.,
-what @code{\ } produces.
-
-Ordinarily, a blank line in the input produces as much blank vertical
-space as a line of text would occupy. You can adjust this by assigning
-to the parameter @code{\blanklineskipamount}:
-@findex blanklineskipamount @r{in obeyed text}
-if you set this negative, the space produced by a blank line will be
-smaller; if positive, larger.
-
-Tabs are not affected by this routine. In particular, if tabs occur
-at the beginning of a line, they will disappear. (If you are trying to
-make @TeX{} do the ``right thing'' with tabs, don't. Use a utility
-program like @i{expand} instead.)
-@cindex tabs

-@node Writing out numbers
-@section Writing out numbers
-
-@cindex numbers, written form of
- @code{\numbername}
-@findex numbername
-produces the written-out form of its argument, i.e., `zero' through
-`ten' for the numbers 0--10, and numerals for all others.
-
-
-@node Mode-specific penalties
-@section Mode-specific penalties
-
-@TeX{}'s built-in @code{\penalty} command simply appends to the
-current list, no matter what kind of list it is. You might intend a
-particular penalty to always be a ``vertical'' penalty, however, i.e.,
-appended to a vertical list. Therefore, Eplain provides
-@code{\vpenalty}
-@findex vpenalty
-and @code{\hpenalty}
-which first leave the other mode and then do @code{\penalty}.
-
-More precisely, @code{\vpenalty} inserts @code{\par} if the current
-mode is horizontal, and @code{\hpenalty} inserts @code{\leavevmode} if
-the current mode is vertical. (Thus, @code{\vpenalty} cannot be used in
-math mode.)
-
-
-@node Auxiliary files
-@section Auxiliary files
-
-@cindex axuiliary files, existence of
-It is common to write some information out to a file to be used on a
-subsequent run. But when it is time to read the file again, you only
-want to do so if the file actually exists. @code{\testfileexistence}
-@findex testfileexistence
-is given an argument which is appended to @code{\jobname},
-@findex jobname
-and sets the conditional @code{\iffileexists}
-@findex iffileexists
-@findex fileexists @r{(conditional)}
-appropriately. For example:
-
-@example
-\testfileexistence@{toc@}%
-\iffileexists
- \input \jobname.toc
-\fi
-@end example
-
-@code{\testfileexistence} takes an optional parameter; when
-given, it will override @code{\jobname} for the root part of the file
-name. For example, if you want to test for the file
-@file{answers.aux}, you can do this with the following:
-
-@example
-\testfileexistence[answers]@{aux@}%
-\iffileexists
- \input answers.aux
-\fi
-@end example
-
-
-@node User-defined environments
-@section User-defined environments
-
-@cindex environments, user-defined
-Plain @TeX{} does not provide ``named'' block structures, only the anonymous
-@code{\begingroup} and @code{\endgroup} pair. The disadvantage of this
-is that when there are several such groups and one is mismatched, it can
-be difficult to find the error. Eplain provides a named block structure
-so that if you forget an @code{\environment} or an
-@code{\endenvironment}, you will (probably) get an error message about
-it.
-
-For example:
-
-@example
-\def\itpar@{
- \environment@{@@italicpar@}
- \it\par
-@}
-\def\enditpar@{
- \par
- \endenvironment@{@@italicpar@}%
-@}
-@end example
-@noindent which could then be used to set italicized paragraphs:
-@example
-\itpar
-If I reprehend anything in this world, it is the use of my oracular
-tongue, and a nice derangement of epitaphs!
-\enditpar
-@end example
-
-The above sort of environment allows nesting. But environments
-shouldn't always be allowed to nest. Put the control sequence
-@code{\checkenv} at the beginning of a macro that is going to define an
-environment that should not be nested.

-@node Page list and page range parsers
-@section Page list and page range parsers
-
-@findex idxparselist
-@findex idxparserange
-@findex idxpagei
-@findex idxpageii
-The macros which Eplain uses to parse the page lists and ranges in the
-index, @code{\idxparselist} and @code{\idxparserange} (@pxref{Page
-destinations for index terms}), are sometimes useful when defining page
-number encapsulators. They take one argument, text to parse. When a
-page list (range) is not present, they set @code{\idxpagei} to be
-@code{\empty}; when a list (range) is detected, they set
-@code{\idxpagei} and @code{\idxpageii} to the first and the second page
-numbers, respectively.
-
-@findex setidxpagelistdelimiter
-@findex setidxpagerangedelimiter
-Eplain's defaults for the page list and page range delimiters are the
-same as those in MakeIndex, a comma followed by a space (@samp{, }) and
-two dashes (@samp{--}), respectively. If you customize MakeIndex to use
-different delimiters, you must not forget to let Eplain know about them
-with the commands
-
-@example
-\setidxpagelistdelimiter@{@var{list-delim}@}
-\setidxpagerangedelimiter@{@var{page-delim}@}
-@end example
-
-@noindent These commands save the @var{list-delim} and
-@var{page-delim} delimiters in
-@findex idxpagelistdelimiter
-@findex idxpagerangedelimiter
-@code{\idxpagelistdelimiter} and @code{\idxpagerangedelimiter},
-respectively.
-
-@cindex underlining page numbers in index
-@cindex index, underlining page numbers
-@findex ituline
-For example, you may want to define a page number markup command which
-italicizes and properly underlines page ranges by underlining only the
-page numbers and not the delimiter:
-
-@findex idxpagerangedelimiter
-@example
-\def\ituline#1@{%
- @{\it
- \idxparserange@{#1@}%
- \ifx\idxpagei\empty
- % The argument is a single page number.
- \underbar@{#1@}%
- \else
- % The argument is a page range.
- \underbar@{\idxpagei@}\idxpagerangedelimiter\underbar@{\idxpageii@}%
- \fi@}%
-@}
-@end example
-
-@noindent Note that the @code{\ituline} macro is not aware of page

-@code{\hlidx} and @code{\hlidxpage} will break up the page lists before
-calling the user's page encapsulator (@pxref{Page destinations for index

-need to design a macro which also takes care of the lists, you can
-extend @code{\ituline} with an additional call to @code{\idxparselist}.

-@cindex diagnostics
-@cindex tracing
-Plain @TeX{} provides the @code{\tracingall} command, to turn on the
-maximum amount of tracing possible in @TeX{}. The (usually voluminous)
-output from @code{\tracingall} goes both on the terminal and into the
-transcript file.
-@findex tracingall
-It is sometimes easier to have the output go only to the transcript
-file, so you can peruse it at your leisure and not obscure other output
-to the terminal. So, Eplain provides the command @code{\loggingall}.
-@findex loggingall
-(For some reason, this command is available in Metafont, but not in
-@TeX{}.)
-
-It is also sometimes useful to see the complete contents of boxes.
-@code{\tracingboxes} does this. (It doesn't affect whether or not the
-contents
-@findex tracingboxes
-are shown on the terminal.)
-
-You can turn off all tracing with @code{\tracingoff}.
-@findex tracingoff
-
-You can also turn logging on and off globally, so you don't have to
-worry about whether or not you're inside a group at the time of command.
-These variants are named @code{\gloggingall}
-@findex gloggingall
-and @code{\gtracingall}.
-@findex gtracingall
-
-Finally, if you write your own help messages (see @code{\newhelp}
-@cindex help messages
-@cindex error messages
-in @cite{The @TeX{}book}), you want a convenient way to break lines in
-them. This is what @TeX{}'s @code{\newlinechar} parameter is for;
-@cindex newlinechar
-however, plain @TeX{} doesn't set @code{\newlinechar}. Therefore,
-Eplain defines it to be the character @code{^^J}.
-
-For example, one of Eplain's own error messages is defined as follows:
-@example
-\newhelp\envhelp@{Perhaps you forgot to end the previous^^J%
- environment? I'm finishing off the current group,^^J%
- hoping that will fix it.@}%
-@end example
-
-
-@node Rules
-@section Rules
-
-The default dimensions of rules are defined in chapter@tie{}21 of the
-@cite{The @TeX{}book}. To sum up what is given there, the ``thickness''
-of rules is
-@cindex rule thickness
-0.4pt by default. Eplain defines three parameters that let you change
-this dimension: @code{\hruledefaultheight}, @code{\hruledefaultdepth},
-@findex hruledefaultheight
-@findex hruledefaultdepth
-and @code{\vruledefaultwidth}. By default, they are defined as
-@findex vruledefaultwidth
-@cite{The @TeX{}book} describes.
-
-But it would be wrong to redefine @code{\hrule} and @code{\vrule}. For
-one thing, some macros in plain @TeX{} depend on the default dimensions
-being used; for another, rules are used quite heavily, and the
-performance impact of making it a macro can be noticeable. Therefore,
-to take advantage of the default rule parameters, you must use
-@code{\ehrule}
-@findex ehrule
-and @code{\evrule}.
-@findex evrule

-@node Citations
-@section Citations
-
-@cindex citations
-@cindex bibliographies
-Bibliographies are part of almost every technical document. To handle
-them easily, you need two things: a program to do the tedious
-formatting, and a way to cite references by labels, rather than by
-numbers. The Bib@TeX{} program, written by Oren Patashnik, takes care
-@cindex Bib@TeX{}
-@cindex Patashnik, Oren
-of the first item; the citation commands in @LaTeX{}, written to be used
-@cindex @LaTeX{}
-with Bib@TeX{}, take care of the second. Therefore,
-Eplain adopts the use of Bib@TeX{}, and virtually the same interface as
-@LaTeX{}.
-
-The general idea is that you put citation commands in the text of your
-document, and commands saying where the bibliography data is. When you
-run @TeX{}, these commands produce output on the file with the same root
-name as your document (by default) and the extension @file{.aux}.
-@pindex .aux @r{file}
-@findex jobname
-Bib@TeX{} reads this file. You should put the bibliography data in a
-file or files with the extension @file{.bib}. Bib@TeX{} writes out a
-file with the same root
-@pindex .bib @r{file}
-name as your document and extension @file{.bbl}. Eplain reads this file
-@pindex .bbl @r{file}
-the next time you run your document through @TeX{}. (It takes
-multiple passes to get everything straight, because usually after seeing
-your bibliography typeset, you want to make changes in the @file{.bib}
-file, which means you have to run Bib@TeX{} again, which means you have
-to run @TeX{} again@dots{}) An annotated example of the whole process is
-given below.
-
-If your document has more than one bibliography---for example, if it
-is a collection of papers---you can tell Eplain to use a different root
-name for the @file{.bbl} file by defining the control sequence
-@code{\bblfilebasename}.
-@findex bblfilebasename
-The default definition is simply @code{\jobname}.
-
-See the document @cite{Bib@TeX{}ing} (whose text is in the file
-@file{btxdoc.tex}, which should be in the Eplain distribution you got)
-for information on how to write your @t{.bib} files. Both the
-Bib@TeX{} and the Eplain distributions contain several examples, also.
-
-The @code{\cite}
-@findex cite
-command produces a citation in the text of your document. The exact
-printed form the citation will take is under your control;
-@pxref{Formatting citations}. @code{\cite} takes one
-required argument, a comma-separated list of cross-reference labels
-(@pxref{Cross-references}, for exactly what characters are allowed in
-such labels). Warning: spaces in this list are taken as part of the
-following label name, which is probably not what you expect.
-@cindex citations, undefined
-The @code{\cite} command also produces a command
-in the @t{.aux} file that tells Bib@TeX{} to retrieve the given reference(s)
-from the @t{.bib} file. @code{\cite} also takes one optional argument,
-which you specify within square brackets, as in @LaTeX{}. This text is
-simply typeset after the citations. (See the example below.)
-
-Eplain can create hypertext links for citations pointing to the relevant
-bibliography entries; @pxref{Citation hyperlinks}.
-
-Another command, @code{\nocite},
-@findex nocite
-puts the given reference(s) into the bibliography, but produces nothing
-in the text.
-
-The @code{\bibliography}
-@findex bibliography
-command is next. It serves two purposes: producing the typeset
-bibliography, and telling Bib@TeX{} the root names of the @t{.bib}
-files. Therefore, the argument to @code{\bibliography} is a comma
-separated list of the @t{.bib} files (without the @samp{.bib}). Again,
-spaces in this list are significant.
-
-You tell Bib@TeX{} the particular style in which you want your
-bibliography typeset with one more command:
-@code{\bibliographystyle}.
-@findex bibliographystyle
-The argument to this is a single filename @var{style}, which tells
-Bib@TeX{} to look for a file @var{style}@t{.bst}.
-@pindex .bst @r{files}
-See the document @cite{Designing Bib@TeX{} styles} (whose text is in the
-@file{btxhak.tex}) for information on how to write your own styles.
-
-Eplain automatically reads the citations from the @t{.aux} file when
-your job starts.
-
-If you don't want to see the messages about undefined citations, you
-can say @code{\xrefwarningfalse} before making any citations.
-@findex xrefwarningfalse
-Eplain automatically does this if the @t{.aux} file does not exist.
-You can restore the default by saying @code{\xrefwarningtrue}.
-
-Here is a @TeX{} input file that illustrates the various commands.
-
-@example
-\input eplain % Reads the .aux file.
-Two citations to Knuthian works:
- \cite[note]@{surreal,concrete-math@}.
-\beginsection@{References.@}\par % Title for the bibliography.
-\bibliography@{knuth@} % Use knuth.bib for the labels.
-\bibliographystyle@{plain@} % Number the references.
-\end % End of the document.
-@end example
-@cindex Knuth, Donald Ervin
-@cindex Graham, Ronald L.
-@cindex numbered references
-@cindex references, numbered
-
-If we suppose that this file was named @file{citex.tex} and that the
-bibliography data is in @file{knuth.bib} (as the @code{\bibliography}
-command says), the following commands do what's required. (@samp{$ }
-represents the shell prompt.)
-
-@example
-$ tex citex (produces undefined citation messages)
-$ bibtex citex (read knuth.bib and citex.aux, write citex.bbl)
-$ tex citex (read citex.bbl, still have undefined citations)
-$ tex citex (one more time, to resolve the references)
-@end example
-
-@pindex texi2dvi
-@noindent (The @command{texi2dvi} program can help you automate this
-process, @pxref{Invoking Eplain}.)
-
-The output looks something like (because we used the @t{plain}
-bibliography style):

-@cindex citations, formatting
-
-You may wish to change Eplain's formatting of citations; i.e., the
-result of your @code{\cite} commands. By default, the citation labels
-are printed one after another, separated by commas and enclosed in
-brackets, using the main text font. Some formats require other styles,
-such as superscripted labels. You can accomodate such formats by
-redefining the following macros.
-
-@table @code
-@itemx \printcitestart
-@item \printcitefinish
-@findex printcitestart
-@findex printcitefinish
-Eplain expands these macros at the begining and end of the list of
-citations for each @code{\cite} command. By default, they produce a
-@samp{[} and @samp{]}, respectively.
-
-@item \printbetweencitations
-@findex printbetweencitations
-If a @code{\cite} command has multiple citations, as in
-@code{\cite@{acp,texbook@}}, Eplain expands this macro in between each
-pair of citations. By default, it produces a comma followed by a space.
-
-@item \printcitenote
-@findex printcitenote
-This macro takes one argument, which is the optional note to the
-@code{\cite} command. If the @code{\cite} command had no note, this
-macro isn't used. Otherwise, it should print the note. By default, the
-note is preceded with a comma and a space.
-@end table

-Here is an example, showing you could produce citations as
-superscripted labels, with the optional notes in parentheses.

-You may wish to change Eplain's formatting of the bibliography,
-especially with respect to the fonts that are used. Therefore, Eplain
-provides the following control sequences:
-
-@table @code
-
-@item \biblabelwidth
-@findex biblabelwidth
-This control sequence represents a @code{\dimen} register, and its value
-is the width of the widest label in the bibliography. Although it is
-unlikely you will ever want to redefine it, you might want
-to use it if you redefine @code{\biblabelprint}, below.
-
-@item \biblabelprint
-@findex biblabelprint
-This macro takes one argument, the label to print. By default, the
-label is put in a box of width @code{\biblabelwidth}, and is followed by
-an enspace. When you want to change the spacing around the labels, this
-is the right macro to redefine.
-
-@item \biblabelcontents
-@findex biblabelcontents
-This macro also takes one argument, the label to print. By default, the
-label is printed using the font @code{\bblrm} (below), and enclosed in
-brackets. When you want to change the appearance of the label, but not
-the spacing around it, this is the right macro to redefine.
-
-@item \bblrm
-@findex bblrm
-@cindex bibliography fonts
-The default font used for printing the bibliography.
-
-@item \bblem
-@findex bblem
-The font used for printing the titles and other ``emphasized'' material.
-
-@item \bblsc
-@findex bblsc
-In some styles, authors' names are printed in a caps-and-small-caps
-font. In those cases, this font is used.
-
-@item \bblnewblock
-@findex bblnewblock
-This is invoked between each of the parts of a bibliography entry. The
-default is to leave some extra space between the parts; you could
-redefine it to start each part on a new line (for example). A part is
-simply a main element of the entry; for example, the author is a part.
-(It was @LaTeX{} that introduced the (misleading, as far as I am
-concerned) term `block' for this.)
-
-@item \biblabelextraspace
-@findex biblabelextraspace
-Bibliography entries are typeset with a hanging indentation of
-@code{\biblabelwidth} plus this. The default is @code{.5em}, where the
-em width is taken from the @code{\bblrm} font. If you want to change
-this, you should do it inside @code{\bblhook}.
-
-@item \bblhook
-@findex bblhook
-@cindex bibliography items, extra space between
-This is expanded before reading the @t{.bbl} file. By
-default, it does nothing. You could, for example, define it to set the
-bibliography fonts, or produce the heading for the references. Two
-spacing parameters must be changed inside @code{\bblhook}:
-@code{\parskip}, which produces extra space between the items; and
-@code{\biblabelextraspace}, which is described above.
-(By the way, @code{\hookappend} won't work with @code{\bblhook}, despite
-the names. Just use @code{\def}.)

-By default, @TeX{} centers displayed material. (Displayed material is
-just whatever you put between @code{$$}'s---it's not necessarily
-mathematics.) Many layouts would be better served if the displayed
-material was left-justified. Therefore, Eplain provides the command
-@code{\leftdisplays},
-@findex leftdisplays
-which indents displayed material by @code{\parindent} plus
-@code{\leftskip}, plus @code{\leftdisplayindent}.
-@findex leftdisplayindent
-
-You can go back to centering displays with @code{\centereddisplays}.
-@findex centereddisplays
-(It is usually poor typography to have both centered and left-justified
-displays in a single publication, though.)
-
-@code{\leftdisplays} also changes the plain @TeX{} commands that deal
-with alignments inside math displays,
-@code{\displaylines},
-@findex displaylines
-@code{\eqalignno},
-@findex eqalignno
-and @code{\leqalignno},

-is called at the beginning of every display (presumably by invoking it
-in @TeX{}'s @code{\everydisplay} parameter), and to define
-@code{\generaldisplay}.

-@node Lists
-@section Lists
-
-@cindex lists
-@cindex numbered lists
-@cindex ordered list
-@cindex unordered lists
-
-Many documents require lists of items, either numbered or simply
-enumerated. Plain @TeX{} defines one macro to help with creating lists,
-@code{\item}, but that is insufficient in many cases. Therefore,
-Eplain provides two pairs of commands:
-
-@table @code
-
-@itemx \numberedlist @dots{} \endnumberedlist
-@item \orderedlist @dots{} \endorderedlist
-@findex numberedlist
-@findex endnumberedlist
-@findex orderedlist
-@findex endorderedlist
-These commands (they are synonyms) produce a list with the items
-numbered sequentially, starting from one. A nested @code{\numberedlist}
-labels the items with lowercase letters, starting with `a'. Another
-nested @code{\numberedlist} labels the items with roman numerals. Yet
-more deeply nested numbered lists label items with @samp{*}.
-
-@item \unorderedlist @dots{} \endunorderedlist
-@findex unorderedlist
-@findex endunorderedlist
-This produces a list with the items labelled with small black boxes
-(``square bullets''). A nested @code{\unorderedlist} labels items with
-em-dashes. Doubly (and deeper) nested unordered lists label items with
-`*'s.
-
-@end table
-
-The two kinds of lists can be nested within each other, as well.
-
-In both kinds of lists, you begin an item with @code{\li}.
-@findex li
-An item may continue for several paragraphs. Each item starts a
-paragraph.
-
-You can give @code{\li} an optional argument, a cross-reference label.
-It's defined to be the ``marker'' for the current item. This is useful
-if the list items are numbered. You can produce the value of the label
-with @code{\xrefn}. @xref{Cross-references}.
-
-Eplain can create hypertext links for the markers produced by
-@code{\xrefn} pointing to the relevant list item; @pxref{List
-hyperlinks}.
-
-You can also say @code{\listcompact}
-@findex listcompact
-right after @code{\numberedlist} or @code{\unorderedlist}. The items in
-the list will then not have any extra space between them
-(@pxref{Formatting lists}). You might want to do this if the items in
-this particular list are short.
-
-Here is an example:
-@example
-\numberedlist\listcompact
-\li The first item.
-\li The second item.
-
-The second paragraph of the second item.

-Several registers define the spacing associated with lists. It is
-likely that their default values won't suit your particular layout.
-
-@table @code
-@item \abovelistskipamount, \belowlistskipamount
-@findex abovelistskipamount
-@findex belowlistskipamount
-The vertical glue inserted before and after every list, respectively.
-
-@item \interitemskipamount
-@findex interitemskipamount
-The vertical glue inserted before each item except the first.
-@code{\listcompact} resets this to zero, as mentioned above.
-
-@item \listleftindent, \listrightindent
-@findex listleftindent
-@findex listrightindent
-@code{\listrightindent} is the amount of space by which the list is
-indented on the right; i.e., it is added to @code{\rightskip}.
-@code{\listleftindent} is the amount of space, @emph{relative to}
-@code{\parindent}, by which the list is indented on the left. Why treat
-the two parameters differently? Because (a)@tie{}it is more useful to
-make the list indentation depend on the paragraph indentation;
-(b)@tie{}footnotes aren't formatted right if @code{\parindent} is reset
-to zero.
-
-@end table
-
-The three vertical glues are inserted by macros, and preceded by
-penalties: @code{\abovelistskip}
-@findex abovelistskip
-does @code{\vpenalty\abovelistpenalty}
-@findex abovelistpenalty
-and then @code{\vskip\abovelistskip}. @code{\belowlistskip}
-@findex belowlistskip
-and @code{\interitemskip}
-@findex interitemskip
-are analogous.
-
-In addition, the macro @code{\listmarkerspace}
-@findex listmarkerspace
-is called to separate the item label from the item text. This is set to
-@code{\enspace} by default.
-
-If you want to change the labels on the items, you can redefine these
-macros:
-@code{\numberedmarker}
-@findex numberedmarker
-or @code{\unorderedmarker}.
-@findex unorderedmarker
-The following registers might be useful if you do:
-
-@table @code
-@item \numberedlistdepth, \unorderedlistdepth
-@findex numberedlistdepth
-@findex unorderedlistdepth
-These keep track of the depth of nesting of the two kinds of lists.
-
-@item \itemnumber, \itemletter
-@findex itemnumber
-@findex itemletter
-These keep track of the number of items that have been seen in the current
-numbered list. They are both integer registers. The difference is that
-@code{\itemnumber} starts at one, and @code{\itemletter} starts at 97,
-i.e., lowercase `a'.
-
-@end table
-
-You can also redefine the control sequences that are used internally,
-if you want to do something radically different: @code{\beginlist}
-@findex beginlist
-is invoked to begin both kinds of lists; @code{\printitem}
-@findex printitem
-is invoked to print the label (and space following the label) for each
-item; and @code{\endlist}
-@findex endlist
-is invoked to end both kinds of
-lists.

-for example, part of a computer program. The @code{\listing}
-@findex listing
-command is given one argument, a filename, and produces the contents of
-that file in your document. @code{\listing} expands @code{\listingfont}
-to set the current font. The default value of @code{\listingfont}
-@findex listingfont
-is @code{\tt}.
-
-You can take arbitrary actions before reading the file by defining the macro
-@code{\setuplistinghook}.
-@findex setuplistinghook
-This is expanded just before the file is input.
-
-If you want to have line numbers on the output, you can say
-@code{\let\setuplistinghook = \linenumberedlisting}.
-@findex linenumberedlisting
-The line numbers are stored in the count register @code{\lineno} while
-the file is being read. You can redefine the macro
-@code{\printlistinglineno} to change how they are printed.
-
-You can produce in-line verbatim text in your document with @code{\verbatim}.
-@findex verbatim

-You can change the verbatim escape character from the default @samp{|}
-with @code{\verbatimescapechar @var{char}}; for example, this changes
-it to @samp{@@}.
-
-@example
-\verbatimescapechar \@@
-@end example
-
-@noindent The backslash is not necessary in some cases, but is in
-others, depending on the catcode of the character. The argument to
-@code{\verbatimescapechar} is used as @code{\catcode `@var{char}}, so
-the exact rules follow that for @code{\catcode}.
-
-Because @code{\verbatim} must change the category code of special
-characters, calling inside a macro definition of your own does not work
-properly. For example:
-
-@example
-\def\mymacro@{\verbatim &#%|endverbatim@}% Doesn't work!
-@end example
-
-To accomplish this, you must change the category codes yourself before
-making the macro definition. Perhaps @code{\uncatcodespecials} will
-help you (@pxref{Category codes}).

-@cindex table of contents
-@cindex contents
-
-Producing a table of contents that is both useful and aesthetic is one
-of the most difficult design problems in any work. Naturally, Eplain
-does not pretend to solve the design problem. Collecting the raw data
-for a table of contents, however, is much the same across documents.
-Eplain uses an auxiliary file with extension @file{.toc}
-@pindex .toc @r{file}
-(and the same root name as your document) to save the information.
-
-To write an entry for the table of contents, you say
-@code{\writetocentry@{@var{part}@}@{@var{text}@}},
-@findex writetocentry
-where @var{part} is the type of part this entry is, e.g.,
-@samp{chapter}, and @var{text} is the text of the title.
-@code{\writetocentry} puts an entry into the @t{.toc} file that looks
-@findex toc@dots{}entry
-like @code{\toc@var{part}entry@{@var{text}@}@{@var{page number}@}}. The
-@var{text} is written unexpanded.
-
-@findex writenumberedtocentry
-A related command, @code{\writenumberedtocentry}, takes one additional
-argument, the first token of which is expanded at the point of the
-@code{\writenumberedtocentry}, but the rest of the argument is not
-expanded. The usual application is when the parts of the document are
-numbered. On the other hand, the one-level expansion allows you to use
-the argument for other things as well (author's names in a proceedings,
-say), and not have accents or other control sequences expanded. The
-downside is that if you @emph{want} full expansion of the third
-argument, you don't get it---you must expand it yourself, before you
-call @code{\writenumberedtocentry}.
-
-For example:
-
-@example
-\writenumberedtocentry@{chapter@}@{A $\sin$ wave@}@{\the\chapno@}
-\writetocentry@{section@}@{A section title@}
-@end example
-
-@noindent Supposing @code{\the\chapno} expanded to @samp{3} and that the
-@code{\write}'s occurred on pages eight and nine, respectively, the
-above writes the following to the @t{.toc} file:
-
-@example
-\tocchapterentry@{A $\sin$ wave@}@{3@}@{8@}
-\tocsectionentry@{A section title@}@{9@}
-@end example
-
-@findex readtocfile
-You read the @t{.toc} file with the command @code{\readtocfile}.
-Naturally, whatever @code{\toc@dots{} entry} commands that were written
-to the file must be defined when @code{\readtocfile} is invoked. Eplain
-has minimal definitions for @code{\tocchapterentry},
-@code{\tocsectionentry}, and @code{\tocsubsectionentry}, just to prevent
-undefined control sequence errors in common cases. They aren't suitable
-for anything but preliminary proofs.
-
-Each of @code{\writetocentry} and @code{\writenumberedtocentry} opens
-the @t{.toc} file for writing, thereby deleting the information from the
-previous run. You should therefore arrange that @code{\readtocfile} be
-called @emph{before} the first call to a @code{\writetoc@dots{}} macro.
-@code{\readtocfile} does not itself delete the information
-from the @t{.toc} file, so that you can call it several times,
-e.g., to create both a short
-@cindex table of contents, short
-and normal table of contents. (To produce this in particular, define
-@code{\tocsectionentry} to produce nothing while you are reading
-@t{.toc} file for a short table of contents (@pxref{Macro arguments}).)
-
-On the other hand, if you don't want to rewrite the @t{.toc} file at
-all, perhaps because you are only running @TeX{} on part of your
-manuscript, you can set @code{\rewritetocfilefalse}.
-@findex ifrewritetocfile
-@findex rewritetocfile @r{(conditional)}
-
-By default, the @file{.toc} file has the root @code{\jobname}. If your
-document has more than one contents---for example, if it is a collection
-of papers, some of which have their own contents---you can tell Eplain
-to use a different root name by defining the control sequence
-@code{\tocfilebasename}.
-@findex tocfilebasename
-
-@cindex list of figures
-@cindex list of tables
-@findex definecontentsfile
-In addition to the usual table of contents, you may want to have a list
-of figures, list of tables, or other such contents-like list. You can do
-this with @code{\definecontentsfile@{@var{abbrev}@}}. All of the
-above commands are actually a special case that Eplain predefines with
-
-@example
-\definecontentsfile@{toc@}
-@end example
-
-@noindent The @var{abbrev} is used both for the file extension and in
-the control sequence names.

-@section Cross-references
-
-@cindex cross-references
-It is often useful to refer the reader to other parts of your document;
-but putting literal page, section, equation, or whatever numbers in the
-text is certainly a bad thing.
-
-Eplain therefore provides commands for symbolic cross-references. It
-uses an auxiliary file with extension @t{.aux}
-@pindex .aux @r{file}
-(and the same root name as your document) to keep track of the
-information. Therefore, it takes two passes to get the cross-references
-right---one to write them out, and one to read them in. Eplain
-automatically reads the @t{.aux} file at the first reference; after
-reading it, Eplain reopens it for writing.
-
-You can control whether or not Eplain warns you about undefined
-labels. @xref{Citations}.
-
-@cindex labels, characters valid in
-Labels in Eplain's cross-reference commands can use characters of
-category code eleven (letter), twelve (other), ten (space), three (math
-shift), four (alignment tab), seven (superscript), or eight (subscript).
-For example, @samp{(a1 $&^_} is a valid label (assuming the category
-codes of plain @TeX{}), but @samp{%#\@{} has no valid characters.
-
-You can also do symbolic cross-references for bibliographic citations
-and list items. @xref{Citations}, and @ref{Lists}.
-
-Eplain can create hypertext links for the cross-references;

-@findex definexref
-Eplain provides the command @code{\definexref} for general
-cross-references. It takes three arguments: the name of the label (see
-section above for valid label names), the value of the label (which can
-be anything), and the ``class'' of the reference---whether it's a
-section, or theorem, or what. For example:
-
-@example
-\definexref@{sec-intro@}@{3.1@}@{section@}
-@end example
-
-@noindent Of course, the label value is usually generated by another
-macro using @TeX{} count registers or some such.
-
-@code{\definexref} doesn't actually define @var{label}; instead, it
-writes out the definition to the @t{.aux} file, where Eplain will read
-it on the next @TeX{} run.
-
-The @var{class} argument is used by the @code{\ref} and @code{\refs}
-commands. See the next section.

-@cindex defining general references
-@cindex references, defining general
-@cindex cross-references, defining general
-
-To retrieve the value of the label defined via @code{\definexref} (see
-the previous section), Eplain provides the following macros:
-
-@table @code
-
-@findex refn
-@itemx \refn@{@var{label}@}
-@findex xrefn
-@item \xrefn@{@var{label}@}
-@code{\refn} and @code{\xrefn} (they are synonyms) produce the bare
-definition of @var{label}. If @var{label} isn't defined, issue a
-warning, and produce @var{label} itself instead, in typewriter. (The
-warning isn't given if @code{\xrefwarningfalse}.)
-@findex xrefwarning @r{conditional}
-
-@findex ref
-@item \ref@{@var{label}@}
-Given the class @var{c} for @var{label} (see the description of
-@code{\definexref} in the previous section), expand the control sequence
-@code{\@var{c} word} (if it's defined) followed by a tie. Then call
-@code{\refn} on @var{label}. (Example below.)
-
-@findex refs
-@item \refs@{@var{label}@}
-Like @code{\ref}, but append the letter @samp{s} to the
-@code{\@dots{}word}.
-
-@end table
-
-The purpose of the @code{\@dots{}word} macro is to produce the word
-`Section' or `Figure' or whatever that usually precedes the actual
-reference number.
-
-Here is an example:
-
-@example
-\def\sectionword@{Section@}
-\definexref@{sec-intro@}@{3.1@}@{section@}
-\definexref@{sec-next@}@{3.2@}@{section@}
-See \refs@{sec-intro@} and \refn@{sec-next@} @dots{}

-@findex xrdef
-Define @var{label} to be the current page number. This produces no

-
-@item \xref@{@var{label}@}
-@findex xref
-Produce the text `p.@tie{}@var{pageno}', which is the usual form for
-cross-references. The @var{pageno} is actually @var{label}'s
-definition; if @var{label} isn't defined, the text of the label itself
-is printed. The `p.@tie{}' prefix is defined by @code{\xrefpageword}.
-@findex xrefpageword

-@node Equation references
-@section Equation references
-
-@cindex equations, references to
-@cindex equations, numbering
-Instead of referring to pages, it's most useful if equation labels
-refer to equation numbers. Therefore, Eplain reserves a @code{\count}
-register, @code{\eqnumber},
-@findex eqnumber
-for the current equation number, and increments it at each
-numbered equation.
-
-Here are the commands to define equation labels and then refer to them:
-
-@table @code
-
-@item \eqdef@{@var{label}@}
-@findex eqdef
-This defines @var{label} to be the current value of @code{\eqnumber},
-and, if the current context is not inner, then produces a @code{\eqno}
-command. (The condition makes it possible to use @code{\eqdef} in an
-@code{\eqalignno} construction, for example.) The text of the equation
-number is produced using @code{\eqprint}. @xref{Formatting equation
-references}.
-
-@cindex empty equation labels
-@cindex labels, empty equation
-@cindex equations, giving numbers to all
-If @var{label} is empty, you still get an equation number (although
-naturally you can't reliably refer to it). This is useful if you want
-to put numbers on all equations in your document, and you don't want to
-think up unique labels.
-
-@cindex empty equation labels, referring to
-@cindex labels, empty equation, referring to
-To refer to the last equation with the empty label, you just use the
-empty label in one of the equation reference macros (see below). This
-can be handy when you want to refer to an equation shortly after its
-definition, say, in the sentence following the displayed equation, and
-do not intend to refer to the equation later. But use this trick with
-extreme caution: if later you change the text and insert another
-empty definition between the original definition and the reference,
-the reference will start to refer to the new empty-labeled equation.
-
-@item \eqdefn@{@var{label}@}
-@findex eqdefn
-This is like @code{\eqdef}, except it always omits the @code{\eqno}
-command. It can therefore be used in places where @code{\eqdef} can't;
-for example, in a non-displayed equation. The text of the equation
-number is not produced, so you can also use it in the (admittedly
-unusual) circumstance when you want to define an equation label but not
-print that label.
-
-@item \eqref@{@var{label}@}
-@findex eqref
-This produces a formatted reference to @var{label}. If @var{label} is
-undefined (perhaps because it is a forward reference), it just produces
-the text of the label itself. Otherwise, it calls @code{\eqprint}.
-
-@item \eqrefn@{@var{label}@}
-@findex eqrefn
-This produces the cross-reference text for @var{label}. That is, it
-is like @code{\eqref}, except it doesn't call @code{\eqprint}.

-@node Formatting equation references
-@subsection Formatting equation references
-
-@cindex equation numbers, formatting of
-Both defining an equation label and referring to it should usually
-produce output. This output is produced with the @code{\eqprint} macro,
-which takes one argument, the equation number being defined or referred
-to. By default, this just produces @samp{(@var{number})}, where
-@var{number} is the equation number. To produce the equation number in
-a different font, or with different surrounding symbols, or whatever,
-you can redefine @code{\eqprint}.
-@findex eqprint
-For example, the following definition would print all equation numbers
-in italics. (The extra braces define a group, to keep the font change
-from affecting surrounding text.)
-
-@example
-\def\eqprint#1@{@{\it (#1)@}@}
-@end example
-
-In addition to changing the formatting of equation numbers, you might
-to add more structure to the equation number; for example, you might
-want to include the chapter number, to get equation numbers like
-`(1.2)'. To achieve this, you redefine @code{\eqconstruct}.
-@findex eqconstruct
-For example:
-
-@example
-\def\eqconstruct#1@{\the\chapternumber.#1@}
-@end example
-
-@noindent
-(If you are keeping the chapter number in a count register named
-@code{\chapternumber}, naturally.)
-
-The reason for having both @code{\eqconstruct} and @code{\eqprint} may
-not be immediately apparent. The difference is that @code{\eqconstruct}
-affects the text that cross-reference label is defined to be, while
-@code{\eqprint} affects only what is typeset on the page. The example
-just below might help.
-
-Usually, you want equation labels to refer to equation numbers. But
-sometimes you might want a more complicated text. For example, you
-might have an equation `(1)', and then have a variation several pages
-later which you want to refer to as `(1*)'.
-
-Therefore, Eplain allows you to give an optional argument (i.e.,
-arbitrary text in square brackets) before the cross-reference label to
-\eqdef. Then, when you refer to the equation, that text is produced.
-Here's how to get the example just mentioned:
-
-@example
-$$@dots{}\eqdef@{a-eq@}$$
-@dots{}
-$$@dots{}\eqdef[\eqrefn@{a-eq@}*]@{a-eq-var@}$$
-In \eqref@{a-eq-var@}, we expand on \eqref@{a-eq@}, @dots{}
-@end example
-
-We use @code{\eqrefn} in the cross-reference text, not
-@code{\eqref}, so that @code{\eqprint} is called only once.
-
-
-@node Subequation references
-@subsection Subequation references
-
-@cindex equations, groups of
-@cindex subequations, referring to
-Eplain also provides for one level of substructure for equations. That
-is, you might want to define a related group of equations with numbers
-like `2.1' and `2.2', and then be able to refer to the group as a whole:
-``@dots{} in the system of equations (2)@dots{}''.
-
-The commands to do this are @code{\eqsubdef} and
-@findex eqsubdef
-@code{\eqsubdefn}.
-@findex eqsubdefn
-They take one @var{label} argument like their counterparts above,
-and generally behave in the same way. The difference is in how they
-construct the equation number: instead of using just @code{\eqnumber},
-they also use another counter, @code{\subeqnumber}.
-@findex subeqnumber
-This counter is advanced by one at every @code{\eqsubdef} or
-@code{\eqsubdefn}, and reset to zero at every @code{\eqdef} or
-@code{\eqdefn}.
-
-You use @code{\eqref} to refer to subequations as well as main
-equations.
-
-To put the two together to construct the text that the label will
-produce, they use a macro @code{\eqsubreftext}.
-@findex eqsubreftext
-This macros takes two arguments, the ``main'' equation number (which,
-because the equation label can be defined as arbitrary text, as
-described in the previous section, might be anything at all) and the
-``sub'' equation number (which is always just a number). Eplain's
-default definition just puts a period between them:
-@example
-\def\eqsubreftext#1#2@{#1.#2@}%
-@end example
-
-@noindent You can redefine @code{\eqsubreftext} to print however you
-like. For example, this definition makes the labels print as `2a',
-`2b', and so on.
-@example
-\newcount\subref
-\def\eqsubreftext#1#2@{%
- \subref = #2 % The space stops a <number>.
- \advance\subref by 96 % `a' is character code 97.
- #1\char\subref
-@}
-@end example
-
-@noindent Sadly, we must define a new count register, @code{\subref},
-instead of using the scratch count register @code{\count255}, because
-@samp{#1} might include other macro calls which use @code{\count255}.

-
-@cindex indexing
-@cindex sorting an index
-
-Eplain provides support for generating raw material for an index, and
-for typesetting a sorted index. A separate program must do the actual
-collection and sorting of terms, because @TeX{} itself has no support
-for sorting.
-
-Eplain can create hypertext links pointing from the index to the index
-terms; @pxref{Index hyperlinks}.
-
-@cindex URL for MakeIndex
-@pindex makeindex
-Eplain's indexing commands were designed to work with the program
-MakeIndex, available from CTAN hosts in
-@file{tex-archive/indexing/makeindex}; MakeIndex is also commonly
-included in prepackaged @TeX{} distributions. It is beyond the scope of
-this manual to explain how to run MakeIndex, and all of its many
-options. See @url{http://www.ctan.org/tex-archive/indexing/makeindex/}
-
-The basic strategy for indexing works like this:
-
-@enumerate
-
-@pindex .idx @r{files}
-@item For a document @file{foo.tex}, Eplain's indexing commands (e.g.,
-@code{\idx}; see the section `Indexing terms' below) write the raw index
-material to @file{foo.idx}.
-
-@pindex .ind @r{files}
-@item MakeIndex reads @file{foo.idx}, collects and sorts the index, and
-writes the result to @file{foo.ind}.
-
-@item Eplain reads and typesets @file{foo.ind} on a subsequent run of
-@TeX{}. See the section `Typesetting an index' below.
-
-@end enumerate
-
-@pindex texi2dvi
-@noindent The @command{texi2dvi} program can help you automate this
-process, @pxref{Invoking Eplain}.
-
-@cindex multiple indexes
-@cindex indexes, multiple
-@findex defineindex
-If your document needs more than one index, each must have its own
-file. Therefore, Eplain provides the command @code{\defineindex}, which
-takes an argument that is a single letter, which replaces @samp{i} in
-the filenames and in the indexing command names described below. For
-example,
-
-@example
-\defineindex@{m@}
-@end example
-
-@noindent defines the command @code{\mdx} to write to the file
-@file{foo.mdx}. Eplain simply does @code{\defineindex@{i@}} to define
-the default commands.

-@cindex indexing terms
-@cindex silent indexing
-
-Indexing commands in Eplain come in pairs: one command that only
-writes the index entry to the @samp{.idx} file (see above section), and
-one that also typesets the term being indexed. The former always starts
-with @samp{s} (for ``silent''). In either case, the name always includes
-@samp{@var{I}dx}, where @var{I} is the index letter, also described
-above. Eplain defines the index @samp{i} itself, so that's what we'll
-use in the names below.
-
-@cindex subterm in indexing
-The silent form of the commands take a subterm as a trailing optional
-argument. For example, @code{\sidx@{truth@}[definition of]} on page 75
-makes an index entry that will eventually be typeset (by default) as
-
-@display
-truth

-
-@item
-@findex sidx
-@findex idx
-@code{\sidx@{@var{term}@}[@var{subterm}]} makes an index entry for
-@var{term}, optionally with subterm @var{subterm}.
-@code{\idx@{@var{term}@}} also produces @var{term} as output. Example:
-
-@example
-\sidx@{truth@}[beauty of]
-The beauty of truth is \idx@{death@}.
-@end example
-
-Subterms at the second and further levels can also be
-specified in @var{subterm}, using the
-@code{\idxsubentryseparator} character to separate
-them. This character is by default @samp{!}.
-
-@item
-@findex sidxname
-@findex idxnameseparator
-@findex idxname
-@code{\sidxname@{@var{First M.}@}@{@var{von Last}@}[@var{subterm}]}
-makes an index
-entry for @samp{@var{von Last}, @var{First M.}}. You can change the
-@samp{, } by redefining @code{\idxnameseparator}.
-@code{\idxname@{@var{First M.}@}@{@var{von Last}@}} also produces @var{First M. von
-Last} as output. (These commands are useful special cases of @code{\idx}
-and @code{\sidx}.) Example:
-
-@example
-\sidxname@{Richard@}@{Stark@}
-\idxname@{Donald@}@{Westlake@} has written many kinds of novels, under
-almost as many names.
-@end example
-
-@item
-@findex sidxmarked
-@findex idxmarked
-@code{\sidxmarked\@var{cs}@{@var{term}@}[@var{subterm}]} makes an index
-entry for @code{@var{term}[@var{subterm}]}, but @var{term} will be put
-in the index as @code{\@var{cs}@{term@}}, but still sorted as just
-@var{term}. @code{\idxmarked\@var{cs}@{@var{term}@}} also typesets
-@code{\@var{cs}@{term@}}. This provides for the usual ways of changing
-the typesetting of index entries. Example:
-
-@example
-\def\article#1@{``#1''@}
-\sidxmarked\article@{Miss Elsa and Aunt Sophie@}
-Peter Drucker's \idxmarked\article@{The Polanyis@} is a remarkable
-essay about a remarkable family.
-@end example
-
-@item
-@findex idxsubmarked
-@findex sidxsubmarked
-@code{\sidxsubmarked@{@var{term}@}\@var{cs}@{subterm@}} makes an index
-entry for @var{term}, @var{subterm} as usual, but also puts @var{subterm} in
-the index as @code{\@var{cs}@{term@}}.
-@code{\idxsubmarked@{@var{term}@}\@var{cs}@{subterm@}} also typesets
-@code{@var{term} \@var{cs}@{subterm@}}, in the unlikely event that your
-syntax is convoluted enough to make this useful. Example:
-
-@example
-\def\title#1@{@{\sl #1@}@}
-\sidxsubmarked@{Anderson, Laurie@}\title@{Strange Angels@}
-The \idxsubmarked@{Anderson@}\title@{Carmen@} is a strange twist.

-
-@cindex index entry general sorting
-@cindex sorting of index entries
-The commands above rely on MakeIndex's feature for separating sorting of
-an index entry's from its typesetting. You can use this directly by
-specifying an index entry as @code{@var{sort}@@@var{typeset}}. For
-example:
-
-@example
-\sidx@{Ap-weight@@$A_\pi$-weight@}
-@end example
-
-@noindent will sort as @code{Ap-weight}, but print with the proper math.
-The @code{@@} here is MakeIndex's default character for this purpose.
-See @url{http://www.ctan.org/tex-archive/indexing/makeindex/}. To make an index
-entry with an @code{@@} in it, you have to escape it with a backslash;
-Eplain provides no macros for doing this.

-After any index command, Eplain runs
-@code{\hookaction@{afterindexterm@}}. Because the index commands always
-add a whatsit item to the current list, you may wish to preserve a
-penalty or space past the new item. For example, given a conditional
-@code{\if@@aftersctnhead} set true when you're at a section heading, you
-could do:
-
-@example
-\hookaction@{afterindexterm@}@{\if@@aftersctnhead \nobreak \fi@}
-@end example

-@node Modifying index entries
-@subsubsection Modifying index entries
-
-@cindex modifying index entries' page numbers
-@cindex index entries' page numbers, modifying
-
-All the index commands described in the previous section take an initial
-optional argument before the index term, which modify the index entry's
-meaning in various ways. You can specify only one of the following in
-any given command, except that @code{begin} and @code{end} can be
-specified together with @code{pagemarkup=@var{cs}} (separate them with
-a comma without a following space, like this:
-@code{[begin,pagemarkup=defn]}).
-
-These work via MakeIndex's ``encapsulation'' feature. @xref{Customizing
-indexing}, if you're not using the default characters for the
-MakeIndex operators. The other optional argument (specifying a subterm)
-is independent of these.
-
-Here are the possibilities:
-
-@table @code
-
-@item begin
-@itemx end
-@findex begin @r{for index entries}
-@findex end @r{for index entries}
-@cindex index entries and ranges
-@cindex ranges and index entry
-These mark an index entry as the beginning or end of a range. The index
-entries must match exactly for MakeIndex to recognize them.
-Example:
-
-@example
-\sidx[begin]@{future@}[Cohen, Leonard]
-@dots{}
-\sidx[end]@{future@}[Cohen, Leonard]
-@end example
-
-@noindent will typeset as something like
-
-@display
-future,
- Cohen, Leonard, 65--94
-@end display
-
-@item see
-@findex see @r{for index entries}
-@cindex see, and index entries
-@cindex cross-referencing index entries
-@cindex index entries, and cross-referencing
-This marks an index entry as pointing to another; the real index term is
-an additional (non-optional) argument to the command. Thus you can
-anticipate a term readers may wish to look up, yet which you have
-decided not to index. Example:
-
-@example
-\sidx[see]@{analysis@}[archetypal]@{archetypal criticism@}
-@end example
-
-@noindent becomes
-
-@display
-analysis,
- archetypal, @i{see} archetypal criticism
-@end display
-
-@item seealso
-@findex seealso @r{for index entries}
-Similar to @code{see} (the previous item), but also allows for normal
-index entries of the referencing term. Example:
-
-@example
-\sidx[seealso]@{archetypal criticism@}[elements of]@{dichotomies@}
-@end example
-
-@noindent becomes
-
-@display
-archetypal criticism,
- elements of, 75, 97, 114, @i{see also} dichotomies
-@end display
-
-(Aside for the academically curious: The archetypally critical book I
-took these dichotomous examples from is Laurence Berman's @cite{The
-Musical Image}, which I happened to co-design and typeset.)
-
-@item pagemarkup=@var{cs}
-This puts @code{\@var{cs}} before the page number in the typeset index,
-thus allowing you to underline definitive entries, italicize examples,
-and the like. You do @emph{not} precede the control sequence @var{cs}
-with a backslash. (That just leads to expansive difficulties.) Naturally
-it is up to you to define the control sequences you want to use. Example:
-
-@example
-\def\defn#1@{@{\sl #1@}@}
-\sidx[pagemarkeup=defn]@{indexing@}
-@end example
-
-@noindent becomes something like
-
-@example
-indexing, @code{\defn@{75@}}
-@end example
-
-@end table

-@node Proofing index terms
-@subsubsection Proofing index terms
-
-@cindex proofing index terms
-@cindex index terms, proofing
-@cindex margins, index terms in
-
-As you are reading through a manuscript, it is helpful to see what terms
-have been indexed, so you can add others, catch miscellaneous errors,
-etc. (Speaking from bitter experience, I can say it is extremely
-error-prone to leave all indexing to the end of the writing, since it
-involves adding many @TeX{} commands to the source files.)
-
-@findex indexproofterm
-@findex indexprooffont
-@pindex cmtt8
-So Eplain puts index terms in the margin of each page, if you
-set @code{\indexproofingtrue}. It is @code{false} by default. The terms
-are typeset by the macro @code{\indexproofterm}, which takes a single
-argument, the term to be typeset. Eplain's definition of
-@code{\indexproofterm} just puts it into an @code{\hbox}, first doing
-@code{\indexprooffont}, which Eplain defines to select the font
-@code{cmtt8}. With this definition long terms run off the page, but
-since this is just for proofreading anyway, it seems acceptable.
-
-@findex pageno
-@findex insidemargin
-@findex hoffset
-@findex outsidemargin
-@findex indexsetmargins
-On the other hand, we certainly don't want the index term to run into
-the text of the page, so Eplain uses the right-hand side of the page
-rather than the left-hand page (assuming a language read left to right
-here). So @code{\ifodd\pageno}, Eplain kerns by @code{\outsidemargin},
-otherwise by @code{\insidemargin}. If those macros are undefined,
-@code{\indexsetmargins} defines them to be one inch plus @code{\hoffset}.
-
-@findex @@indexproof @r{insertion class}
-@findex indexproofunbox
-@findex makeheadline
-@cindex output routine and index proofing
-To get the proofing index entries on the proper page, Eplain defines a new
-insertion class @code{\@@indexproof}. To unbox any index proofing
-material, Eplain redefines @code{\makeheadline} to call
-@code{\indexproofunbox} before the original @code{\makeheadline}. Thus,
-if you have your own output routine, that redefines or doesn't use
-@code{\makeheadline}, it's up to you to call @code{\indexproofunbox} at
-the appropriate time.

-@subsection Typesetting an index
-
-@cindex typesetting an index
-@cindex index typesetting
-@findex readindexfile
-
-The command @code{\readindexfile@{i@}} reads and typesets the
-@file{.ind} file that MakeIndex outputs (from the @file{.idx} file which
-the indexing commands in the previous sections write). Eplain defines a
-number of commands that support the default MakeIndex output.
-
-@findex indexfilebasename
-@findex jobname
-More precisely, @code{\readindexfile} reads
-@code{\indexfilebasename.@var{index-letter}nd}, where the
-@var{index-letter} is the argument. @code{\indexfilebasename} is
-@code{\jobname} by default, but if you have different indexes in
-different parts of a book, you may wish to change it, just as with
-bibliographies (@pxref{Citations}).
-
-@findex begin@{theindex@}
-@findex end@{theindex@}
-MakeIndex was designed to work with @LaTeX{}; therefore, by default the
-@file{.ind} file starts with @code{\begin@{theindex@}} and ends with
-@code{\end@{theindex@}}. If no @code{\begin} has been defined, Eplain
-defines one to ignore its argument and set up for typesetting the index
-(see below), and also defines a @code{\end} to ignore its argument. (In
-a group, naturally, since there is a primitive @code{\end}).
-
-@findex parindent @r{in indexes}
-@cindex index fonts
-@findex indexfonts
-@cindex double columns in indexes
-Eplain calls @code{\indexfonts}, sets @code{\parindent = 0pt}, and does
-@code{\doublecolumns} (@pxref{Multiple columns}) at the
-@code{\begin@{theindex@}}. @code{\indexfonts} does nothing by default;
-it's just there for you to override. (Indexes are usually typeset in
-smaller type than the main text.)
-
-@findex beginindex @r{hook}
-It ends the setup with @code{\hookrun@{beginindex@}}, so you can
-override anything you like in that hook (@pxref{Hooks}). For example:
-
-@example
-\hookaction@{beginindex@}@{\triplecolumns@}
-@end example
-
-@findex item @r{in indexes}
-@findex subitem @r{in indexes}
-@findex subsubitem @r{in indexes}
-@cindex index entry formatting
-@cindex formatting index entries
-@cindex space above index entries
-@cindex continued index entries
-@cindex index entry continuations
-MakeIndex turns each main index entry into an @code{\item}, subentries
-into @code{\subitem}, and subsubentries into @code{\subsubitem}. By
-default, the first line of main entries are not indented, and subentries
-are indented 1em per level. Main entries are preceded by a @code{\vskip}
-of @code{\aboveitemskipamount}, @code{0pt plus2pt} by default. Page
-breaks are encouraged before main entries (@code{\penalty -100}), but
-prohibited afterwards---Eplain has no provision for ``continued''
-index entries.
-
-All levels do the following:
-
-@findex hangindent @r{for index entries}
-@findex raggedright @r{for index entries}
-@findex hyphenpenalty @r{for index entries}
-@example
-\hangindent = 1em
-\raggedright
-\hyphenpenalty = 10000
-@end example
-
-@findex indexitem @r{hook}
-Each entry ends with @code{\hookrun@{indexitem@}}, so you can change any
-of this. For example, to increase the allowable rag:
-
-@example
-\hookaction@{indexitem@}@{\advance\rightskip by 2em@}
-@end example
-
-@findex indexspace
-@cindex index groupings
-Finally, MakeIndex outputs @code{\indexspace} between each group of
-entries in the @file{.ind} file. Eplain makes this equivalent to
-@code{\bigbreak}.

-@node Customizing indexing
-@subsection Customizing indexing

-@cindex customizing indexing
-
-@findex afterindexterm
-@cindex commas after index terms
-@cindex after index terms
-By default, MakeIndex outputs @samp{, } after each term in the index. To
-change this, you can add the following to your MakeIndex style
-(@file{.ist}) file:
-
-@example
-delim_0 "\\afterindexterm "
-delim_1 "\\afterindexterm "
-delim_2 "\\afterindexterm "
-@end example
-
-@noindent Eplain makes @code{\afterindexterm} equivalent to
-@code{\quad}.
-
-You can also change the keywords Eplain recognizes (@pxref{Modifying
-index entries}):
-
-@table @code
-
-@item \idxrangebeginword
-@findex idxrangebeginword
-`begin'
-
-@item \idxrangeendword
-@findex idxrangeendword
-`end'

-`see'
-
-@item \idxseealsocmdword
-@findex idxseealsocmdword
-`seealso'
-
-@end table
-
-You can also change the magic characters Eplain puts into the
-@file{.idx} file, in case you've changed them in the @code{.ist} file:
-
-@table @code
-
-@item \idxsubentryseparator
-@findex idxsubentryseparator
-@samp{!}
-
-@item \idxencapoperator
-@findex idxencapoperator
-@samp{|}
-
-@item \idxbeginrangemark
-@findex idxbeginrangemark
-@samp{(}
-
-@item \idxendrangemark
-@findex idxendrangemark
-@samp{)}
-
-@end table
-
-There is no macro for the @code{actual} (@samp{@@} by default)
-character, because it's impossible to make it expand properly.
-
-@findex idxpagenum
-@cindex see also index entries and sorting
-You can change the (imaginary) page number that ``see also''
-entries sort as by redefining @code{\idxmaxpagenum}. This is 99999 by
-default, which is one digit too many for old versions of MakeIndex.
-
-@findex indexseeword
-@findex indexseealsowords
-@findex seevariant
-@findex indexsee
-@findex indexseealso
-The words output by Eplain for ``see'' and ``see also'' index entries
-are defined by @code{\indexseeword} and @code{\indexseealsowords}
-respectively. You can change the typeface used for these words by
-redefining @code{\seevariant}. And finally, the macros
-@code{\indexsee} and @code{\indexseealso} actually produce the ``see
-@dots{}'' entries, so you can redefine them if you want something
-entirely different. If you do redefine them, make them take two
-parameters, the term being referenced and the @code{\idxmaxpagenum}
-(the latter should normally be ignored). See the example below.
-
-@findex see @r{for index entries}
-@cindex see, and index entries
-@cindex cross-referencing index entries
-@cindex index entries, and cross-referencing
-@cindex commas in cross-referencing index entries
-Unfortunately, it is impossible to reliably control the commas
-produced by MakeIndex in front of ``see @dots{}'' entries in the
-@file{.ind} file, either at MakeIndex level or at Eplain level.
-However, the
-@pindex sed
-@command{sed} script named @command{trimsee}
-@pindex trimsee
-distributed with Eplain in the @file{test} directory can be used to
-filter out these commas from the output of MakeIndex. For example,
-suppose you want the following style for your ``see @dots{}'' entries:
-
-@display
-analysis,
- archetypal (@i{see} archetypal criticism)
-archetypal criticism,
- elements of, 75, 97, 114 (@i{see also} dichotomies)
-@end display
-
-@noindent You would need to redefine these macros in your @TeX{}
-file:
-
-@example
-\def\indexsee#1#2@{(@{\seevariant \indexseeword\/ @}#1)@}
-\def\indexseealso#1#2@{(@{\seevariant \indexseealsowords\/ @}#1)@}
-@end example
-
-@noindent and then filter out the commas in front of the ``see @dots{}''
-entries by running the following command to produce the @file{.ind}
-file (assuming the name of the @file{.idx} file is @file{myfile.idx}
-and the @file{trimsee} script is placed in the current directory):
-
-@example
-prompt$ cat myfile.idx | makeindex | ./trimsee > myfile.ind
-@end example
-
-By default, @file{trimsee} uses default page list separators and
-default ``see @dots{}'' command names. If you set up MakeIndex to use
-different page list separator or change the names of @code{\indexsee}
-and @code{\indexseealso} commands, it is possible to adjust the
-@file{trimsee} script through its command line options, which are the
-following:
-
-@table @option
-@item -i @var{is}
-Use @var{is} as a regular expression matching separator before ``see
-@dots{}'' commands in the input (default: @samp{, \+}).
-
-@item -o @var{os}
-Use @var{os} as a separator to replace @var{is} before ``see @dots{}''
-commands (default: @samp{ }).
-
-@item -s @var{see}
-Use @var{see} as a regular expression matching ``see @dots{}''
-commands (default: @samp{\\indexsee}).
-
-@item -h
-@itemx --help
-Print a usage message.
-
-@item -v
-@itemx --version
-Print version.

-@file{trimsee} reads input from the standard input, and directs its
-output to the standard output.

-@node Justification
-@section Justification
-
-@cindex centering
-@cindex left-justification
-@cindex right-justification
-@cindex justification
-Eplain defines three commands to conveniently justify multiple
-lines of text: @code{\flushright}, @code{\flushleft}, and
-@code{\center}.
-@findex flushright
-@findex flushleft
-@findex center
-
-They all work in the same way; let's take @code{\center} as the
-example. To start centering lines, you say @code{\center} inside a
-group; to stop, you end the group. Between the two commands, each
-end-of-line in the input file also starts a new line in the output file.
-
-The entire block of text is broken into paragraphs at blank lines,
-so all the @TeX{} paragraph-shaping parameters apply in the usual way.
-This is convenient, but it implies something else that isn't so
-convenient: changes to any linespacing parameters, such as
-@code{\baselineskip}, will have @emph{no effect} on the paragraph in
-which they are changed. @TeX{} does not handle linespacing changes
-within a paragraph (because it doesn't know where the line breaks are
-until the end of the paragraph).
-
-The space between paragraphs is by default one blank line's worth.
-You can adjust this space by assigning to @code{\blanklineskipamount};
-@findex blanklineskipamount @r{in justified text}
-this (vertical) glue is inserted after each blank line.
-
-Here is an example:
-@example
-@{\center First line.
-
- Second line, with a blank line before.
-@}
-@end example
-
-This produces:
-
-@center First line.
-@center
-@center Second line, with a blank line before.
-
-You may wish to use the justification macros inside of your own
-macros. Just be sure to put them in a group. For example, here is how
-a title macro might be defined:
-
-@example
-\def\title@{\begingroup\titlefont\center@}
-\def\endtitle@{\endgroup@}
-@end example
-
-
-@node Tables
-@section Tables
-
-@cindex tables
-@cindex alignments
-Eplain provides a single command, @code{\makecolumns},
-@findex makecolumns
-to make generating one particular kind of table easier. More ambitious
-macro packages might be helpful to you for more difficult applications.
-The files @file{ruled.tex} and @file{TXSruled.tex}, available from
-@samp{lifshitz.ph.utexas.edu} in @file{texis/tables}, is the only one I
-know of.
-
-Many tables are homogenous, i.e., all the entries are semantically the
-same. The arrangement into columns is to save space on the page, not
-to encode different meanings. In this kind of the table, it is useful to
-have the column breaks chosen automatically, so that you can add or
-delete entries without worrying about the column breaks.
-
-@code{\makecolumns} takes two arguments: the number of entries in the
-table, and the number of columns to break them into. As you can see
-from the example below, the first argument is delimited by a slash, and
-the second by a colon and a space (or end-of-line). The entries for the
-table then follow, one per line (not including the line with the
-@code{\makecolumns} command itself).
-
-@code{\parindent} defines the space to the left of the
-table. @code{\hsize} defines the width of the table.
-So you can adjust the position of the table on the page by assignments
-to these parameters, probably inside a group.
-
-You can also control the penalty at a page break before the
-@code{\makecolumns} by setting the parameter
-@code{\abovecolumnspenalty}.
-@findex abovecolumnspenalty
-Usually, the table is preceded by some explanatory text. You wouldn't
-want a page break to occur after the text and before the table, so
-Eplain sets it to @code{10000}. But if the table produced by
-@code{\makecolumns} is standing on its own, @code{\abovecolumnspenalty}
-should be decreased.
-
-If you happen to give @code{\makecolumns} a smaller number of entries
-than you really have, some text beyond the (intended) end of the table
-will be incorporated into the table, probably producing an error
-message, or at least some strange looking entries. And if you give
-@code{\makecolumns} a larger number of entries than you really have,
-some of the entries will be typeset as straight text, probably also
-looking somewhat out of place.
-
-Here is an example:
-@example
-% Arrange 6 entries into 2 columns:
-\makecolumns 6/2: % This line doesn't have an entry.
-one
-two
-three
-four
-five
-six
-Text after the table.
-@end example
-
-This produces `one', `two', and `three' in the first column, and
-`four', `five', and `six' in the second.
-
-
-@node Margins
-@section Margins
-
-@cindex margins, changing
-@TeX{}'s primitives describe the type area in terms of an offset from
-the upper left corner, and the width and height of the type. Some
-people prefer to think in terms of the @dfn{margins} at the top, bottom,
-left, and right of the page, and most composition systems other than
-@TeX{} conceive of the page laid out in this way. Therefore, Eplain
-provides commands to directly assign and increment the margins.
-
-@table @code
-@itemx \topmargin = @var{dimen}
-@itemx \bottommargin = @var{dimen}
-@itemx \leftmargin = @var{dimen}
-@item \rightmargin = @var{dimen}
-@findex topmargin
-@findex bottommargin
-@findex leftmargin
-@findex rightmargin
-These commands set the specified margin to the @var{dimen} given.
-The @code{=} and the spaces around it are optional. The control
-sequences here are not @TeX{} registers, despite appearances;
-therefore, commands like @code{\showthe\topmargin} will not do what you
-expect.
-
-@itemx \advancetopmargin by @var{dimen}
-@itemx \advancebottommargin by @var{dimen}
-@itemx \advanceleftmargin by @var{dimen}
-@item \advancerightmargin by @var{dimen}
-@findex advancetopmargin
-@findex advancebottommargin
-@findex advanceleftmargin
-@findex advancerightmargin
-These commands change the specified margin by the @var{dimen} given.
-@end table
-
-Regardless of whether you use the assignment or the advance commands,
-Eplain always changes the type area in response, not the other margins.
-For example, when @TeX{} starts, the left and right margins are both one
-inch. If you then say @code{\leftmargin = 2in}, the right margin will
-remain at one inch, and the width of the lines (i.e., @code{\hsize})
-@findex hsize
-will decrease by one inch.
-
-When you use any of these commands, Eplain computes the old value of
-the particular margin, by how much you want to change it, and then
-resets the values of @TeX{}'s primitive parameters to correspond.
-Unfortunately, Eplain cannot compute the right or bottom margin without
-help: you must tell it the full width and height of the final output
-page. It defines two new parameters for this:
-
-@table @code
-@item \paperheight
-@findex paperheight
-The height of the output page; default is 11truein.
-
-@item \paperwidth
-@findex paperwidth
-The width of the output page; default is 8.5truein.
-@end table
-
-If your output page has different dimensions than this, you must
-reassign to these parameters, as in
-
-@example
-\paperheight = 11truein
-\paperwidth = 17truein
-@end example
-
-
-@node Multiple columns
-@section Multiple columns
-
-@cindex double column output
-@cindex triple column output
-@cindex quadruple column output
-@cindex multiple column output
-Eplain provides for double, triple, and quadruple column output: say
-@code{\doublecolumns},
-@findex doublecolumns
-@code{\triplecolumns},
-@findex triplecolumns
-or @code{\quadcolumns},
-@findex quadcolumns
-and from that point on, the manuscript will be
-set in columns. To go back to one column, say
-@code{\singlecolumn}.
-@findex singlecolumn
-
-@cindex column balancing with @code{\singlecolumn}
-@cindex balancing of columns with @code{\singlecolumn}
-You may need to invoke @code{\singlecolumn} to balance the columns
-on the last page of output.
-
-@findex columnfill
-@cindex column eject
-@cindex eject in multicolumns
-@findex pagetotal
-To do a ``column eject'', i.e., move to the top of the next column, do
-@code{\columnfill}. This does not actually force an eject, however: it
-merely inserts a kern of size @code{\@@normalvsize} minus
-@code{\pagetotal} (@code{\@@normalvsize} being the usual height of the
-page; to implement multicolumns, Eplain multiplies @code{\vsize} itself
-by the number of columns). In most circumstances, a column break will be
-forced after this kern (during the column splitting operation when the
-whole page is output), as desired.
-
-@findex gutter
-The columns are separated by the value of the dimen parameter
-@code{\gutter}. Default value is two picas.
-@findex gutterbox
-If you want to add vertical material between the columns, use
-@code{\gutterbox}. For example, to put a vertical line between columns,
-define
-@code{\gutterbox} as
-@example
-\def\gutterbox@{\vbox to \dimen0@{\vfil\hbox@{\vrule height\dimen0@}\vfil@}@}%
-@end example
-The dimension counter
-@code{\dimen0}
-contains the height of the column.
-
-All the @code{\@dots{}columns} macros insert the value of the glue parameter
-@code{\abovecolumnskip}
-@findex abovecolumnskip
-before the multicolumn text, and the value of the glue parameter
-@code{\belowcolumnskip}
-@findex belowcolumnskip
-after it. The default value for both of these parameters is
-@code{\bigskipamount}, i.e., one linespace in plain @TeX{}.
-
-The macros take into account only the insertion classes
-@cindex insertion classes
-defined by plain @TeX{}; namely, footnotes and @code{\topinsert}s. If
-you have additional insertion classes, you will need to change
-the implementation.
-
-Also, Eplain makes insertions the full page width. There is no
-provision for column-width insertions.
-
-
-@node Footnotes
-@section Footnotes
-
-@cindex footnotes, numbered
-The most common reference mark for footnotes is a raised number,
-incremented on each footnote. The @code{\numberedfootnote}
-@findex numberedfootnote
-macro provides this. It takes one argument, the footnote text.
-
-If your document uses only numbered footnotes, you could make typing
-@code{\numberedfootnote} more convenient with a command such as:
-
-@example
-\let\footnote = \numberedfootnote
-@end example
-
-After doing this, you can type your footnotes as
-@code{\footnote@{@var{footnote text}@}}, instead of as
-@code{\numberedfootnote@{@var{footnote text}@}}.
-
-Eplain keeps the current footnote number in the count register
-@code{\footnotenumber}. So, to reset the footnote number to zero,
-as you might want to do at, for example, the beginning of a chapter, you
-could say @code{\footnotenumber=0}.
-
-Plain @TeX{} separates the footnote marker from the footnote text by
-an en space (it uses the @code{\textindent} macro). In Eplain, you can
-change this space by setting the dimension register
-@code{\footnotemarkseparation}.
-@findex footnotemarkseparation
-The default is still an en.
-
-You can produce a space between footenotes by setting the glue
-register @code{\interfootnoteskip}.
-@findex interfootnoteskip
-The default is zero.
-
-@code{\parskip} is also set to zero by default before the beginning of
-each footnote (but not for the text of the footnote).
-
-You can also control footnote formatting in a more general way:
-Eplain expands the token register @code{\everyfootnote}
-@findex everyfootnote
-before a footnote is typeset, but after the default values for all the
-parameters have been established. For example, if you want your
-footnotes to be printed in seven-point type, indented by one inch, you
-could say:
-@example
-\everyfootnote = @{\sevenrm \leftskip = 1in@}
-@end example
-
-By default, an @code{\hrule} is typeset above each group of footnotes
-on a page. You can control the dimensions of this rule by setting
-the dimension registers @code{\footnoterulewidth}
-@findex footnoterulewidth
-and @code{\footnoteruleheight}.
-@findex footnoteruleheight
-The space between the rule and the first footnote on the page is
-determined by the dimension register @code{\belowfootnoterulespace}.
-@findex belowfootnoterulespace
-If you don't want any rule at all, set @code{\footenoteruleheight=0pt},
-and, most likely, @code{\belowfootnoterulespace=0pt}. The defaults for
-these parameters typeset the rule in the same way as plain @TeX{}: the
-rule is 0.4 points high, 2 true inches wide, with 2.6 points below it.
-
-The space above the rule and below the text on the page is controlled
-by the glue register @code{\skip\footins}. The default is a plain @TeX{}
-@code{\bigskip}.
-
-Eplain can create hypertext links for the footnote marks; @pxref{Footnote
-hyperlinks}.

-@node Fractions
-@section Fractions
-
-@cindex fractions
-Exercise 11.6 of @cite{The @TeX{}book} describes a macro @code{\frac}
-@findex frac
-for setting fractions, but @code{\frac} never made it into plain @TeX{}.
-So Eplain includes it.
-
-@code{\frac} typesets the numerator and denominator in
-@code{\scriptfont0}, slightly raised and lowered. The numerator and
-denominator are separated by a slash. The denominator must be enclosed
-in braces if it's more than one token long, but the numerator need not
-be. (This is a consequence of @code{\frac} taking delimited arguments;
-see page@tie{}203 of @cite{The @TeX{}book} for an explanation of
-delimited macro arguments.)
-
-For example, @code{\frac 23/@{64@}} turns `23/64' into
-@tex
-\leavevmode
- \kern-.1em \raise .5ex \hbox{\the\scriptfont0 23}@comment
- \kern-.1em $/$@comment
- \kern-.15em \lower .25ex \hbox{\the\scriptfont0 64}@comment
-@end tex
-@ifinfo
-23/64 (you can't see the difference in the Info file)@comment
-@end ifinfo
-.

-
-@node Paths
-@section Paths
-
-@cindex pathnames, breaking
-@cindex filenames, breaking
-@cindex electronic mail addresses, breaking
-
-When you typeset long pathnames, electronic mail addresses, or other
-such ``computer'' names, you would like @TeX{} to break lines at
-punctuation characters within the name, rather than trying to find
-hyphenation points within the words. For example, it would be better to
-break the email address @code{letters@@alpha.gnu.ai.mit.edu} at the
-@samp{@@} or a @samp{.}, rather than at the hyphenation points in
-@samp{letters} and @samp{alpha}.
-
-@findex path
-If you use the @code{\path} macro to typeset the names, @TeX{} will find
-these good breakpoints. The argument to @code{\path} is delimited by
-any character other other than @samp{\} which does not appear in the
-name itself.
-@samp{|} is often a good choice, as in:
-@example
-\path|letters@@alpha.gnu.ai.mit.edu|
-@end example
-
-@findex discretionaries
-You can control the exact set of characters at which breakpoints will be
-allowed by calling @code{\discretionaries}. This takes the same sort of
-delimited argument; any character in the argument will henceforth be a valid
-breakpoint within @code{\path}. The default set is essentially all the
-punctuation characters:
-@example
-\discretionaries |~!@@$%^&*()_+`-=#@{@}[]:";'<>,.?\/|
-@end example
-
-@findex specialpathdelimiters @r{(conditional)}
-If for some reason you absolutely must use @code{\} as the delimiter
-character for @code{\path}, you can set
-@code{\specialpathdelimiterstrue}. (Other delimiter characters can
-still be used.) @TeX{} then processes the @code{\path} argument
-about four times more slowly.
-
-@cindex URL for @file{path.sty}
-The @code{\path} macro comes from @file{path.sty}, written by Nelson
-Beebe and Philip Taylor and available at

-@node Boxes
-@section Boxes
-
-@cindex black boxes
-@cindex rectangles
-The solid rectangle that Eplain uses as a marker in unordered lists
-(@pxref{Lists}) is available by itself: just say @code{\blackbox}.
-@findex blackbox
-
-You can create black boxes of arbitrary size with @code{\hrule} or
-@code{\vrule}.
-
-@cindex open boxes
-@cindex boxes, open
-You can also get unfilled rectangles with @code{\makeblankbox}.
-@findex makeblankbox
-This takes two explicit arguments: the height and depth of the rules that
-define the top and bottom of the rectangle. (The two arguments are
-added to get the width of the left and right borders, so that the
-thickness of the border is the same on all four sides.) It also uses,
-as implicit arguments, the dimensions of @code{\box0} to define the
-dimensions of the rectangle it produces. (The contents of @code{\box0}
-are ignored.)
-
-Here is an example. This small raised open box is suitable for
-putting next to numbers in, e.g., a table of contents.
-
-@example
-\def\openbox@{%
- \ht0 = 1.75pt \dp0 = 1.75pt \wd0 = 3.5pt
- \raise 2.75pt \makeblankbox@{.2pt@}@{.2pt@}
-@}
-@end example
-
-Finally, you can put a box around arbitrary text with @code{\boxit}.
-@findex boxit
-This takes one argument, which must itself be a (@TeX{}) box, and puts a
-printed box around it, separated by @code{\boxitspace}
-@findex boxitspace
-white space (3 points by default) on all four sides. For example:
-
-@example
-\boxit@{\hbox@{This text is boxed.@}@}
-@end example
-
-The reason that the argument must be a box is that when the text is
-more than one line long, @TeX{} cannot figure out the line length for
-itself. Eplain does set @code{\parindent} to zero inside @code{\boxit},
-since it is very unlikely you would want indentation there. (If you do,
-you can always reset it yourself.)
-
-@code{\boxit} uses @code{\ehrule} and @code{\evrule} so that you can
-easily adjust the thicknesses of the box rules. @xref{Rules}.

-@node Checking for PDF output
-@section Checking for PDF output
-
-@cindex URL for pdf@TeX{}
-@cindex PDF output
-@pindex pdftex
-@pindex .pdf @r{files}
-pdf@TeX{} is a @TeX{} variant that can output both @file{.dvi} and
-@file{.pdf} (Adobe's Portable Document Format) files (see
-@url{http://www.ctan.org/tex-archive/systems/pdftex/}). You might
-sometimes want to know whether the target format is @file{.pdf} or
-@file{.dvi}. The @code{\ifpdf}
-@findex ifpdf
-switch can be used to detect pdf@TeX{} in PDF mode:
-
-@example
-\ifpdf
- This text is produced when pdfTeX is in PDF mode.
-\else
- This text is produced when pdfTeX is in DVI mode,
- or when some program other than pdfTeX is used.
-\fi
-@end example
-
-Keep in mind that @code{\ifpdf} is set based on the value of the
-@code{\pdfoutput}
-@findex pdfoutput
-primitive of pdf@TeX{} at the time Eplain is loaded. If you change
-the value of @code{\pdfoutput} after you load Eplain, @code{\ifpdf}
-will not reflect the change.

-Eplain provides a limited support for loading @LaTeX{} packages
-(@file{.sty} files---not @file{.cls}). This will mostly work for
-packages which were designed with plain @TeX{} compatibility in mind,
-which means that most @LaTeX{} packages cannot be loaded. The

-@cindex @LaTeX{} graphics collection
-@pindex miniltx.tex
-@cindex Carlisle, David

-To set up a pseudo-@LaTeX{} environment for the packages, Eplain uses
-@file{miniltx.tex}
-(@url{http://www.ctan.org/tex-archive/macros/plain/graphics/miniltx.tex})
-from the @LaTeX{} graphics collection, written by David Carlisle and
-Sebastian Rahtz (the collection is available at
-@url{http://www.ctan.org/tex-archive/macros/latex/required/graphics/}).
-Eplain extends @file{miniltx.tex} to provide some additional features,
-e.g., support for package options.
-
-
-@menu
-* The \usepackage command:: Command to load packages.
-* Environment for loading packages:: Environment for the \usepackage commands.
-* Packages known to work:: Supported packages.

-@end menu
-
-@node The \usepackage command
-@subsection The @code{\usepackage} command
-
-@findex usepackage
-@code{\usepackage} loads a @LaTeX{} package. Its syntax is similar to
-that of @LaTeX{}'s @code{\usepackage} command:
-
-@example
-\usepackage[@var{options}]@{@var{packages}@}[@var{version}]
-@end example
-
-@noindent where @var{options} is a comma-separated list of package
-options, @var{packages} is a comma-separated list of packages to load
-(without the @file{.sty} suffix), and @var{version} is a package
-version number given as a date in the format @samp{YYYY/MM/DD}. If an
-older version of the package is found, a warning is issued. If
-several packages are loaded within a single @code{\usepackage}
-command, the @var{options} will be applied to each of the packages.
-As usual, parameters in square brackets are optional and can be
-omitted (together with the square brackets).
-
-For example:
-
-@example
-\usepackage[foo,bar]@{pack1,pack2@}[2005/08/29]
-@end example
-
-@noindent will load packages @samp{pack1} and @samp{pack2}, each with
-the options @samp{foo} and @samp{bar}, and will check that each of the
-packages are dated 2005/08/29 or newer.
-
-
-@node Environment for loading packages
-@subsection Environment for loading packages
-
-@findex beginpackages
-@findex endpackages
-Some packages request that certain commands are executed after all
-packages have been loaded. In @LaTeX{}, this means that the commands
-are executed at the beginning of the document, after the so-called
-@dfn{preamble}. Neither plain @TeX{} nor Eplain have any kind of
-preamble; therefore, Eplain requires that all packages be loaded inside
-a @code{\beginpackages...\endpackages} block, for example:
-
-@example
-\beginpackages
- \usepackage[foo,bar]@{pack1@}
- \usepackage@{pack2@}
-\endpackages
-@end example
-
-@noindent This requirement enables Eplain to execute the ``delayed''
-commands at the end of the @code{\beginpackages...\endpackages} block.
-
-For the same reason, it is advisable to specify only one such block
-per document, just like there is only one preamble in @LaTeX{}.

+% This file demonstrates the following features of Eplain:
+%
+% - explicit and implicit hyperlinks;
+% - symbolic cross-references;
+% - inserting external graphics using |\includegraphics| from
+% the \LaTeX\ package |graphicx.sty|.
+% - rotating text using |\rotatebox| from |graphicx.sty|.
+%
+% The compiled demo can be downloaded from
+%
+% http://tug.org/eplain/demo
+%
+% In order to compile this file yourself, you will need the CTAN lion
+% drawing by Duane Bibby from
+%
+% ftp://tug.ctan.org/ftpmaint/CTAN_lion/ctan_lion_350x350.png
+%
+% (thanks, |www.ctan.org|). Place the image file in the same
+% directory with this file, and change to that directory. Now, to
+% produce a PDF, run twice the command
+%
+% pdftex xhyper.tex
+%
+% During the first run, Eplain will write the information about the
+% cross-references into |xhyper.aux|, and during the second run this
+% information will be read by Eplain to typeset the references.
+%
+% Demo case:
+%
+% Suppose you are using pdf\TeX, have a figure you want to insert
+% scaled to $200\,pt$ horizontally, and you want this figure to
+% completely fill the PDF viewer's window whenever the reader
+% selects a link pointing to this figure. Additionally, you want to
+% typeset some text as live hyperlinks, clicking on which will start
+% a Web browser and open a URL.
+
+\input eplain
+
+% Load \LaTeX\ packages.
+\beginpackages
+ % |url.sty| provides the |\url| command which we will use to typeset
+ % a URL. We request that |url.sty| be the version from June~27,

+ % with plain \TeX.
+ \usepackage{url}[2005/06/27]
+ % |color.sty| provides support for colored text; all hyperlinks are
+ % automatically colored by Eplain when this package is loaded. We give

+ \usepackage[dvipsnames]{color}
+ % Finally, we load |graphicx.sty|, for the macros |\includegraphics|
+ % and |\rotatebox|.
+ \usepackage{graphicx}
+\endpackages
+
+% Remember that hyperlinks are off by default. Therefore, we need to
+% enable them.
+\enablehyperlinks
+
+% Customize some hyperlink options. First, we set border width to~$0$
+% for all links to get rid of the default boxes around links (we
+% prefer colored links over the boxed links). Next, we say that all
+% links created by the |url| hyperlink group (which means the |\url|
+% command from |url.sty|) must be colored using the named color
+% |BlueViolet|.
+\hlopts{bwidth=0}
+\hlopts[url]{colormodel=named,color=BlueViolet}
+
+% Inhibit page numbering (we have only one page).
+\nopagenumbers
+
+% Define a class word for the cross-reference class |figure|. This
+% word, when defined, will be automatically prepended by Eplain to the
+% reference created by |\ref| (read on to see its use).

+ % the lion. We use |\definexref| to define the cross-reference
+ % label.
+ \vbox{%
+ % In addition to the cross-reference label, |\definexref| will
+ % create a hyperlink destination with the same label. Therefore,
+ % we customize this destination to do what we need. We say that
+ % destination type for the hyperlink group |definexref| (to which
+ % |\definexref| belongs) should be |fitr|. This destination type
+ % will magnify the rectangle specified by the options |width|,
+ % |height| and |depth| to the PDF viewer's window. Therefore, we
+ % set those options accordingly with |\hldestopts| (notice the use
+ % of |depth| instead of |height|---we will want the rectangle to
+ % extend {\it downward}, to cover the image which will come
+ % next). Notice that these settings will be isolated within the
+ % current group (i.e., the |\vbox| we're constructing).
+ \hldesttype[definexref]{fitr}%
+ \hldestopts[definexref]{width=\wd\imgbox,height=0pt,depth=\ht\imgbox}%
+ % We define a symbolic label so that we can later refer
+ % to the figure with |\ref|. The command |\definexref| does
+ % exactly that. The last argument to |\definexref| specifies
+ % class of the label, which determines the word used by |\ref| in
+ % front of the reference text (remember that we've defined
+ % |\figureword| above).
+ \definexref{#1}{\the\fignumber}{figure}%
+ % Finally, produce the image which we've been stashing in the box
+ % register |\imgbox|.
+ \box\imgbox
+ }%
+ \medskip
+}
+
+% Create the figure.
+\fig{CTANlion}{ctan_lion_350x350}{Lion in the archives}{200pt}
+
+% Finished with the fun part, we can relax and typeset some
+% hyperlinks. The easiest way to do that is to use the |\ref|
+% cross-reference command. We can even pass an optional argument
+% (|the lion in|), which will be placed before the class word (|fig.|)
+% and become part of the link (to make sure the reader does not have
+% to aim too hard).
+Show me \ref[the lion in]{CTANlion}.
+
+% If you are the restless kind, here's another way to create a
+% hyperlink to the image: we create a link explicitly by using
+% |\hlstart ... \hlend|. We don't specify the link type, therefore
+% the default type |name| will be used (these are ``named links'',
+% i.e., links pointing to destinations identified by labels). In the
+% options argument, we specify that the border of the link should be
+% inverted when the user clicks the link (|hlight=O|), and also set
+% special color for this link, overriding the default dark-red. The
+% label for the destination is the same as the cross-reference label,
+% |CTANlion|.
+Show me
+\hlstart{}{hlight=O,colormodel=named,color=OliveGreen}{CTANlion}
+ the CTAN lion\hlend.
+
+% Let's now point somewhere outside our document. Eplain homepage is
+% a good target. In the similar spirit, let's consider two
+% approaches. The easy one is to use the |\url| command from
+% |url.sty|. Remember that we have customized the color of |url|
+% hyperlinks, so this one will show up with a different color than the
+% default dark-red.
+Take me to \url{http://tug.org/eplain}.
+
+% The second approach is to create an explicit URL link. We specify
+% yet another border highlighting mode, |P|, which means that the
+% region underneath the bounding box of the link will be drawn inset
+% into the page. Also, let's set the color of the hyperlink to an RGB
+% color |0.4,0.1,0.4|. Since we cannot use commas to separate the
+% color elements inside the options parameter to |\hlstart| (commas
+% there separate options), we have to first create a user-defined
+% color with |\definecolor| from |color.sty|, and use that in
+% |\hlstart|.
+\definecolor{mycolor}{rgb}{0.4,0.1,0.4}
+
+Take me to
+\hlstart{url}{hlight=P,colormodel=,color=mycolor}{http://tug.org/eplain}
+ Eplain homepage\hlend.

+<p><a name="index-special-characters_002c-in-index-entries-265"></a><a name="index-index-entries-with-special-characters-266"></a>
+Indexing terms with special characters can become quite cumbersome
+because you have to keep both TeX and MakeIndex happy at the same
+time. For example, while `<samp><span class="samp">!</span></samp>' has no special meaning for TeX,
+it is a subentry separator for MakeIndex, therefore you'd have to
+escape occurrences of literal `<samp><span class="samp">!</span></samp>' in index terms. Things get
+even more interesting with characters which are special in both TeX
+and MakeIndex.
+
+ <p>This in turn has some implications for the non-silent forms of the
+indexing commands (see <a href="#Indexing-terms">Indexing terms</a>), since TeX and MakeIndex
+use different conventions for escaping characters. For example, this
+will not typeset the exclamation point correctly within the text,
+while it will come out right inside the index, after MakeIndex strips
+the quoting character (`<samp><span class="samp">"</span></samp>'):
+
+<pre class="example"> \idx{"!}
+</pre>
+ <p class="noindent">This would have to be rewritten using the silent command:
+
+<pre class="example"> !\sidx{"!}
+</pre>
+ <p class="noindent">In general, it is a good idea to eschew the non-silent
+commands whenever index term contains anything unusual.
+
+ <p>To understand this keep in mind that indexing commands read the terms
+verbatim so that the terms can embed almost any character, and that's
+what gets written into the <samp><span class="file">.idx</span></samp> file. The non-silent forms
+then typeset the term by rescanning the verbatim copy, therefore for
+the non-silent commands the term, besides being a valid MakeIndex
+input, must also represent a valid TeX input. The silent commands
+don't have this restriction&mdash;their terms only need to become valid
+TeX input <em>after</em> MakeIndex processes the <samp><span class="file">.idx</span></samp> file and
+writes the <samp><span class="file">.ind</span></samp> file. This is what makes the non-silent
+commands less powerful and more troublesome when dealing with special
+characters.

+contain almost any character:
+
+<pre class="example"> \sidx[see]{comments}[with %@with \verbatim %"|endverbatim]
+ {commenting with \verbatim %"|endverbatim}
+</pre>
+ <p class="noindent">We didn't have to escape `<samp><span class="samp">%</span></samp>' in the sort string for
+MakeIndex, while we had to put it inside the verbatim environment
+(see <a href="#Verbatim-listing">Verbatim listing</a>) in the part which MakeIndex will pass back
+to TeX. Also, we had to escape the `<samp><span class="samp">|</span></samp>' character because it
+is special for MakeIndex. If you have trouble understanding the
+reasons for the different types of escaping used, it is best to
+examine the <samp><span class="file">.idx</span></samp> and <samp><span class="file">.ind</span></samp> files resulting from
+processing the above input.
+
+ <p>As was mentioned, index terms can embed &ldquo;almost any character&rdquo;, so
+now we'll describe the exceptions.
+
+ <p>The following characters are reset to their usual meanings because
+they are not useful verbatim: multiple consequent spaces are
+converted into a single space; <acronym>ASCII</acronym> tab characters are
+treated as spaces; <acronym>ASCII</acronym> return is treated as end-of-line
+(this means, among other things, that long terms can be broken across
+several lines).
+
+ <p><a name="index-braces_002c-inside-index-entries-270"></a><a name="index-index-entries-containing-braces-271"></a>You have to be careful with the begin- and end-group characters
+(`<samp><span class="samp">{</span></samp>' and `<samp><span class="samp">}</span></samp>' by default). If they are matched, you don't
+have to do anything special. For example:
+
+<pre class="example"> \sidx {braces {, }@braces
+ \verbatim {"|endverbatim, \verbatim }"|endverbatim}
+</pre>
+ <p class="noindent">However, if they are not matched you have two problems on
+hand. The first one is TeX&mdash;you have to instruct TeX to use
+something else as begin- and/or end-group characters. Eplain provides
+an easy way to do this: just define
+<a name="index-idxargopen-272"></a><code>\idxargopen</code> and/or
+<a name="index-idxargclose-273"></a><code>\idxargclose</code> to the begin- and end-group characters you are
+going to use with indexing macros, and use braces inside index terms
+without any restrictions. Here's an example:
+
+<pre class="example"> \def\idxargopen{`\&lt;}
+ \def\idxargclose{`\&gt;}
+ \sidx &lt;left brace "{@left brace \verbatim "{"|endverbatim&gt;
+</pre>
+ <p class="noindent">In this example we've also dealt with the second
+problem&mdash;braces are MakeIndex's grouping characters as well (by
+default), so we have escaped unmatched braces with `<samp><span class="samp">"</span></samp>'.
+
+ <p><a name="index-brackets_002c-inside-index-entries-274"></a><a name="index-index-entries-containing-brackets-275"></a>And the final note: if you need a subentry containing brackets
+(`<samp><span class="samp">[</span></samp>' and `<samp><span class="samp">]</span></samp>'), avoid the optional argument of <code>\sidx</code>
+and friends, and use instead MakeIndex's subentry separator to create
+the subentry with the brackets in it:

As you are reading through a manuscript, it is helpful to see what terms
have been indexed, so you can add others, catch miscellaneous errors,
etc. (Speaking from bitter experience, I can say it is extremely
error-prone to leave all indexing to the end of the writing, since it
involves adding many TeX commands to the source files.)

+TeX (and LaTeX) documents (see <a href="http://arxiv.org/hypertex">http://arxiv.org/hypertex</a>).
+This standard defines a set of hyperlink tags implemented as
+<code>\special</code> commands written into the <acronym>DVI</acronym> file. The
+major advantage of such standard is that a single <samp><span class="file">.dvi</span></samp> file
+containing HyperTeX commands can be viewed by any
+HyperTeX-enabled viewer (e.g., any more or less modern version of
+<a name="index-xdvi-698"></a><code>xdvi</code>) or converted to other file formats (e.g., <acronym>PDF</acronym>)
+by any HyperTeX-enabled <acronym>DVI</acronym> converter (e.g.,

+<a name="index-ps2pdf-702"></a><code>ps2pdf</code> script).
+
+ <p>The downside to the standard is that it is by design &ldquo;the common
+factor&rdquo; of other formats supporting hyperlinks, so many features of a
+particular file format cannot be supported by HyperTeX. Therefore,
+if you need to use special features of a particular format, HyperTeX
+is not a good choice. For the <acronym>PDF</acronym> file format, Eplain
+provides the <code>pdftex</code> and <code>dvipdfm</code> drivers which provide
+fine control over the <acronym>PDF</acronym> options (see <a href="#Hyperlink-drivers-pdftex-and-dvipdfm">Hyperlink drivers pdftex and dvipdfm</a>).

+% This file demonstrates the following features of Eplain:
+%
+% - explicit and implicit hyperlinks;
+% - symbolic cross-references;
+% - inserting external graphics using |\includegraphics| from

+% - rotating text using |\rotatebox| from |graphicx.sty|.
+%
+% The compiled demo can be downloaded from
+%
+% http://tug.org/eplain/demo
+%
+% In order to compile this file yourself, you will need the CTAN lion
+% drawing by Duane Bibby from
+%
+% ftp://tug.ctan.org/ftpmaint/CTAN_lion/ctan_lion_350x350.png
+%
+% (thanks, |www.ctan.org|). Place the image file in the same
+% directory with this file, and change to that directory. Now, to
+% produce a PDF, run twice the command
+%
+% pdftex xhyper.tex
+%
+% During the first run, Eplain will write the information about the
+% cross-references into |xhyper.aux|, and during the second run this
+% information will be read by Eplain to typeset the references.
+%
+% Demo case:
+%
+% Suppose you are using pdf\TeX, have a figure you want to insert
+% scaled to $200\,pt$ horizontally, and you want this figure to
+% completely fill the PDF viewer's window whenever the reader
+% selects a link pointing to this figure. Additionally, you want to
+% typeset some text as live hyperlinks, clicking on which will start
+% a Web browser and open a URL.
+
+\input eplain

+\beginpackages
+ % |url.sty| provides the |\url| command which we will use to typeset
+ % a URL. We request that |url.sty| be the version from June~27,

+ % with plain \TeX.
+ \usepackage{url}[2005/06/27]
+ % |color.sty| provides support for colored text; all hyperlinks are
+ % automatically colored by Eplain when this package is loaded. We give
+ % the |dvipsnames| option because we want to use named colors from the
+ % |dvips| graphics driver.

+ % Finally, we load |graphicx.sty|, for the macros |\includegraphics|
+ % and |\rotatebox|.

+\enablehyperlinks
+
+% Customize some hyperlink options. First, we set border width to~$0$
+% for all links to get rid of the default boxes around links (we
+% prefer colored links over the boxed links). Next, we say that all
+% links created by the |url| hyperlink group (which means the |\url|
+% command from |url.sty|) must be colored using the named color
+% |BlueViolet|.

+
+% Now comes the fun part--constructing the figure for the image of the
+% \CTAN\ lion. We define a macro
+%
+% \fig{LABEL}{FILENAME}{CAPTION}{WIDTH}
+%
+% which creates a figure using LABEL for the cross-reference and
+% hyperlink label, reading the image from file FILENAME, using CAPTION
+% to name the figure, and WIDTH to scale the image horizontally.

+ % the count register is global, even when |\fig| is buried inside a
+ % group.
+ \global\advance\fignumber by 1
+ % We use |\includegraphics| (from |graphicx.sty|) to load the image,
+ % scaled to the specified width, into our ``measuring'' box
+ % |\imgbox|.
+ \setbox\imgbox = \hbox{\includegraphics[width=#4]{#2}}%
+ % To make the demo even more exciting, let's put the figure's
+ % caption to the left of the image into the |\indent| space of the
+ % new paragraph, and rotate the caption~$90^\circ$.
+ \textindent{%
+ \rotatebox{90}{F{\sc IGURE}~\the\fignumber. #3}%
+ }%
+ % Continue the paragraph by constructing a |\vbox| with the image of

+ % label.
+ \vbox{%
+ % In addition to the cross-reference label, |\definexref| will
+ % create a hyperlink destination with the same label. Therefore,
+ % we customize this destination to do what we need. We say that
+ % destination type for the hyperlink group |definexref| (to which
+ % |\definexref| belongs) should be |fitr|. This destination type
+ % will magnify the rectangle specified by the options |width|,
+ % |height| and |depth| to the PDF viewer's window. Therefore, we
+ % set those options accordingly with |\hldestopts| (notice the use
+ % of |depth| instead of |height|---we will want the rectangle to

+ \hldesttype[definexref]{fitr}%
+ \hldestopts[definexref]{width=\wd\imgbox,height=0pt,depth=\ht\imgbox}%
+ % We define a symbolic label so that we can later refer

+ % exactly that. The last argument to |\definexref| specifies

+ % front of the reference text (remember that we've defined
+ % |\figureword| above).

+\fig{CTANlion}{ctan_lion_350x350}{Lion in the archives}{200pt}
+
+% Finished with the fun part, we can relax and typeset some
+% hyperlinks. The easiest way to do that is to use the |\ref|
+% cross-reference command. We can even pass an optional argument
+% (|the lion in|), which will be placed before the class word (|fig.|)
+% and become part of the link (to make sure the reader does not have
+% to aim too hard).
+Show me \ref[the lion in]{CTANlion}.
+
+% If you are the restless kind, here's another way to create a
+% hyperlink to the image: we create a link explicitly by using
+% |\hlstart ... \hlend|. We don't specify the link type, therefore
+% the default type |name| will be used (these are ``named links'',
+% i.e., links pointing to destinations identified by labels). In the
+% options argument, we specify that the border of the link should be
+% inverted when the user clicks the link (|hlight=O|), and also set
+% special color for this link, overriding the default dark-red. The
+% label for the destination is the same as the cross-reference label,

+% Let's now point somewhere outside our document. Eplain homepage is
+% a good target. In the similar spirit, let's consider two
+% approaches. The easy one is to use the |\url| command from
+% |url.sty|. Remember that we have customized the color of |url|
+% hyperlinks, so this one will show up with a different color than the
+% default dark-red.
+Take me to \url{http://tug.org/eplain}.
+
+% The second approach is to create an explicit URL link. We specify
+% yet another border highlighting mode, |P|, which means that the
+% region underneath the bounding box of the link will be drawn inset
+% into the page. Also, let's set the color of the hyperlink to an RGB
+% color |0.4,0.1,0.4|. Since we cannot use commas to separate the
+% color elements inside the options parameter to |\hlstart| (commas
+% there separate options), we have to first create a user-defined
+% color with |\definecolor| from |color.sty|, and use that in
+% |\hlstart|.
+\definecolor{mycolor}{rgb}{0.4,0.1,0.4}
+
+Take me to
+\hlstart{url}{hlight=P,colormodel=,color=mycolor}{http://tug.org/eplain}
+ Eplain homepage\hlend.

+1 Introduction
+**************
+
+The "Eplain" macro package expands on and extends the definitions in
+plain TeX. This manual describes the definitions that you, as either
+an author or a macro writer, might like to use. It doesn't discuss the
+implementation; see comments in the source code (`xeplain.tex') for
+that.
+
+ Eplain is not intended to provide "generic" typesetting
+capabilities, as do LaTeX (written by Leslie Lamport) or Texinfo (written
+by Richard Stallman and others). Instead, it provides definitions that
+are intended to be useful regardless of the high-level commands that
+you use when you actually prepare your manuscript.
+
+ For example, Eplain does not have a command `\section', which would
+format section headings in an "appropriate" way, such as LaTeX's
+`\section'. The philosophy of Eplain is that some people will always
+need or want to go beyond the macro designer's idea of "appropriate".
+Such canned macros are fine--as long as you are willing to accept the
+resulting output. If you don't like the results, or if you are trying
+to match a different format, you are out of luck.
+
+ On the other hand, almost everyone would like capabilities such as
+cross-referencing by labels, so that you don't have to put actual page
+numbers in the manuscript. The author of Eplain is not aware of any
+generally available macro packages that (1) do not force their
+typographic style on an author, and yet (2) provide such capabilities.
+
+ Besides such generic macros as cross-referencing, Eplain contains
+another set of definitions: ones that change the conventions of plain
+TeX's output. For example, math displays in TeX are, by default,
+centered. If you want your displays to come out left-justified, you
+have to plow through `The TeXbook' to find some way to do it, and then
+adapt the code to your own needs. Eplain tries to take care of the
+messy details of such things, while still leaving the detailed
+appearance of the output up to you.
+
+ Finally, numerous definitions turned out to be useful as Eplain was
+developed. They are also documented in this manual, on the chance that
+people writing other macros will be able to use them.
+
+ You can send bug reports or suggestions to <tex-eplain@tug.org>.
+The current version number of Eplain is defined as the macro
+`\fmtversion' at the end of the source file `eplain.tex'. When
+corresponding, please refer to it.
+
+ To get on this mailing list yourself, email
+<tex-eplain-request@tug.org> with a message whose body contains a line
+
+ subscribe YOU@YOUR.PREFERRED.ADDRESS
+
+or visit `http://tug.org/mailman/listinfo/tex-eplain'.
+
+ David Walden had reported his experience with Eplain as a new user.
+The article is available online at
+`http://tug.org/pracjourn/2005-4/walden'. An introductory article
+(written for TUGboat) is also available online at
+`http://tug.org/eplain/misc/tb84katsi.pdf'.
+
+
+File: eplain.info, Node: Installation, Next: Invoking Eplain, Prev: Introduction, Up: Top
+
+2 Installation
+**************
+
+Your TeX installation should already contain a version of Eplain
+(`eplain.tex') in its main `texmf' tree (usually under
+`/usr/share/texmf/tex/eplain/' on Unix systems). To install a newer
+version of Eplain, put the new `eplain.tex' (included in Eplain
+distributions) in the `tex/eplain/' subdirectory of your local `texmf'
+tree. The newer version you install in the local tree should override
+the older one in the main tree.
+
+ The location of the local `texmf' tree obviously depends on your
+operating system and TeX installation. On Unix systems the usual
+location is `/usr/local/share/texmf/'. If you don't have write
+permissions for `/usr/local/share/texmf/', many installations read the
+`texmf' tree in the user's home directory; `eplain.tex' then should go
+under `~/texmf/tex/eplain/'. For more information about TeX directory
+structure, please see
+`http://www.tex.ac.uk/cgi-bin/texfaq2html?label=tds'.
+
+ If you prefer to install `eplain.tex' in a non-standard place, set
+an environment variable (`TEXINPUTS' for the Web2C port of TeX to Unix)
+to tell TeX how to find it.
+
+ If you want, you can also create a format (`.fmt') file for Eplain,
+which will eliminate the time spent reading the macro source file with
+`\input'. You do this by issuing a sequence of Unix commands something
+like this:
+
+ prompt$ touch eplain.aux
+ prompt$ initex
+ This is TeX, ...
+ **&plain eplain
+ (eplain.tex)
+ *\dump
+ ... MESSAGES ...
+
+You must make sure that `eplain.aux' exists _before_ you run `initex';
+otherwise, warning messages about undefined labels will never be issued.
+
+ You then have to install the resulting `eplain.fmt' in your local
+`texmf' tree or set an environment variable to tell TeX how to find it.
+For the Web2C port of TeX to Unix, format files are usually installed
+under `/usr/local/share/texmf/web2c/' or `/var/lib/texmf/web2c/'; the
+environment variable is `TEXFORMATS'.

+
+3 Invoking Eplain
+*****************
+
+The simplest way to use Eplain is simply to put:
+
+ \input eplain
+
+at the beginning of your input file. The macro file is small enough
+that reading it does not take an unbearably long time--at least on
+contemporary machines.
+
+ In addition, if a format (`.fmt') file has been created for Eplain
+(see the previous section), you can eliminate the time spent reading
+the macro source file. You do this by responding `&eplain' to TeX's
+`**' prompt. For example:
+
+ initex
+ This is TeX, ...
+ **&eplain myfile
+
+ Depending on the implementation of TeX which you are using, you might
+also be able to invoke TeX as `eplain' and have the format file
+automatically read.
+
+ If you write something which you will be distributing to others, you
+won't know if the Eplain format will be loaded already. If it is, then
+doing `\input eplain' will waste time; if it isn't, then you must load
+it. To solve this, Eplain defines the control sequence `\eplain' to be
+the letter `t' (a convention borrowed from Lisp; it doesn't actually
+matter what the definition is, only that the definition exists).
+Therefore, you can do the following:
+
+ \ifx\eplain\undefined \input eplain \fi
+
+where `\undefined' must never acquire a definition.
+
+ Eplain consists of several source files:
+`xeplain.tex'
+ most of the macros;
+
+`arrow.tex'
+ commutative diagram macros (*note Arrow theoretic diagrams::),
+ written by Steven Smith;
+
+`btxmac.tex'
+ bibliography-related macros (*note Citations::);
+
+`ifpdf.sty'
+ sets the switch `\ifpdf', which can be used to detect pdfTeX in
+ PDF mode (*note Checking for PDF output::), written by Heiko
+ Oberdiek;
+
+`path.sty'
+ macro for allowing line breaks at punctuation characters within
+ long pathnames, electronic mail addresses, etc., (*note Paths::),
+ written by Philip Taylor;
+
+`texnames.sty'
+ abbreviations for various TeX-related names (*note Logos::), edited
+ by Nelson Beebe.
+
+
+The file `eplain.tex' is all of these files merged together, with
+comments removed.
+
+ All of these files except `xeplain.tex' can be input individually,
+if all you want are the definitions in that file.
+
+ Also, since the bibliography macros are fairly extensive, you might
+not want to load them, to conserve TeX's memory. Therefore, if the
+control sequence `\nobibtex' is defined, then the bibliography
+definitions are skipped. You must set `\nobibtex' before `eplain.tex'
+is read, naturally. For example, you could start your input file like
+this:
+
+ \let\nobibtex = t
+ \input eplain
+
+By default, `\nobibtex' is undefined, and so the bibliography
+definitions _are_ made.
+
+ Likewise, define `\noarrow' if you don't want to include the
+commutative diagram macros from `arrow.tex', perhaps because you
+already have conflicting ones.
+
+ If you don't want to read or write an `aux' file at all, for any
+kind of cross-referencing, define `\noauxfile' before reading
+`eplain.tex'. This also turns off all warnings about undefined labels.
+
+ Eplain conflicts with AMSTeX (to be precise, with `amsppt.sty'): the
+macros `\cite' and `\ref' are defined by both.
+
+ If you want to use AMSTeX's `\cite', the solution is to define
+`\nobibtex' before reading Eplain, as described above.
+
+ If you have `amsppt.sty' loaded and use `\ref', Eplain writes a
+warning on your terminal. If you want to use the AMSTeX `\ref', do
+`\let\ref = \amsref' after reading Eplain. To avoid the warning, do
+`\let\ref = \eplainref' after reading Eplain and before using `\ref'.
+
+ Sometimes you may need to run TeX more then once on your `.tex' file
+in order to produce and typeset indexes, resolve undefined
+cross-references and/or citations. The shell script `texi2dvi' from
+the Texinfo documentation system (see
+`http://www.gnu.org/software/texinfo') can automate this process: it
+runs BibTeX, MakeIndex and TeX as many times as needed to complete the
+compilation process. You will need to set the `LATEX' environment
+variable to `tex'. For example, in a Bourne-compatible shell, the
+following command will do all the work:
+
+ prompt$ LATEX=tex texi2dvi file.tex
+
+(Despite the name, `texi2dvi' can also produce `.pdf' files; just set
+`LATEX=pdftex'.) See the output from the command `texi2dvi --help' for
+invoking information and a full list of options.

+
+4.1 Diagnostics
+===============
+
+Plain TeX provides the `\tracingall' command, to turn on the maximum
+amount of tracing possible in TeX. The (usually voluminous) output
+from `\tracingall' goes both on the terminal and into the transcript
+file. It is sometimes easier to have the output go only to the
+transcript file, so you can peruse it at your leisure and not obscure
+other output to the terminal. So, Eplain provides the command
+`\loggingall'. (For some reason, this command is available in
+Metafont, but not in TeX.)
+
+ It is also sometimes useful to see the complete contents of boxes.
+`\tracingboxes' does this. (It doesn't affect whether or not the
+contents are shown on the terminal.)
+
+ You can turn off all tracing with `\tracingoff'.
+
+ You can also turn logging on and off globally, so you don't have to
+worry about whether or not you're inside a group at the time of command.
+These variants are named `\gloggingall' and `\gtracingall'.
+
+ Finally, if you write your own help messages (see `\newhelp' in `The
+TeXbook'), you want a convenient way to break lines in them. This is
+what TeX's `\newlinechar' parameter is for; however, plain TeX doesn't
+set `\newlinechar'. Therefore, Eplain defines it to be the character
+`^^J'.
+
+ For example, one of Eplain's own error messages is defined as
+follows:
+
+ \newhelp\envhelp{Perhaps you forgot to end the previous^^J%
+ environment? I'm finishing off the current group,^^J%
+ hoping that will fix it.}%

+
+4.2 Rules
+=========
+
+The default dimensions of rules are defined in chapter 21 of the `The
+TeXbook'. To sum up what is given there, the "thickness" of rules is 0.4pt
+by default. Eplain defines three parameters that let you change this
+dimension: `\hruledefaultheight', `\hruledefaultdepth', and
+`\vruledefaultwidth'. By default, they are defined as `The TeXbook'
+describes.
+
+ But it would be wrong to redefine `\hrule' and `\vrule'. For one
+thing, some macros in plain TeX depend on the default dimensions being
+used; for another, rules are used quite heavily, and the performance
+impact of making it a macro can be noticeable. Therefore, to take
+advantage of the default rule parameters, you must use `\ehrule' and
+`\evrule'.

+
+4.3 Citations
+=============
+
+Bibliographies are part of almost every technical document. To handle
+them easily, you need two things: a program to do the tedious
+formatting, and a way to cite references by labels, rather than by
+numbers. The BibTeX program, written by Oren Patashnik, takes care of
+the first item; the citation commands in LaTeX, written to be used with
+BibTeX, take care of the second. Therefore, Eplain adopts the use of
+BibTeX, and virtually the same interface as LaTeX.
+
+ The general idea is that you put citation commands in the text of
+your document, and commands saying where the bibliography data is.
+When you run TeX, these commands produce output on the file with the
+same root name as your document (by default) and the extension `.aux'. BibTeX
+reads this file. You should put the bibliography data in a file or
+files with the extension `.bib'. BibTeX writes out a file with the same
+root name as your document and extension `.bbl'. Eplain reads this file the
+next time you run your document through TeX. (It takes multiple passes
+to get everything straight, because usually after seeing your
+bibliography typeset, you want to make changes in the `.bib' file,
+which means you have to run BibTeX again, which means you have to run
+TeX again...) An annotated example of the whole process is given below.
+
+ If your document has more than one bibliography--for example, if it
+is a collection of papers--you can tell Eplain to use a different root
+name for the `.bbl' file by defining the control sequence
+`\bblfilebasename'. The default definition is simply `\jobname'.
+
+ See the document `BibTeXing' (whose text is in the file
+`btxdoc.tex', which should be in the Eplain distribution you got) for
+information on how to write your .bib files. Both the BibTeX and the
+Eplain distributions contain several examples, also.
+
+ The `\cite' command produces a citation in the text of your
+document. The exact printed form the citation will take is under your
+control (*note Formatting citations::). `\cite' takes one required
+argument, a comma-separated list of cross-reference labels (*note
+Cross-references::, for exactly what characters are allowed in such
+labels). Warning: spaces in this list are taken as part of the
+following label name, which is probably not what you expect. The
+`\cite' command also produces a command in the .aux file that tells
+BibTeX to retrieve the given reference(s) from the .bib file. `\cite'
+also takes one optional argument, which you specify within square
+brackets, as in LaTeX. This text is simply typeset after the
+citations. (See the example below.)
+
+ Eplain can create hypertext links for citations pointing to the
+relevant bibliography entries (*note Citation hyperlinks::).
+
+ Another command, `\nocite', puts the given reference(s) into the
+bibliography, but produces nothing in the text.
+
+ The `\bibliography' command is next. It serves two purposes:
+producing the typeset bibliography, and telling BibTeX the root names
+of the .bib files. Therefore, the argument to `\bibliography' is a
+comma separated list of the .bib files (without the `.bib'). Again,
+spaces in this list are significant.
+
+ You tell BibTeX the particular style in which you want your
+bibliography typeset with one more command: `\bibliographystyle'. The
+argument to this is a single filename STYLE, which tells BibTeX to look
+for a file STYLE.bst. See the document `Designing BibTeX styles'
+(whose text is in the `btxhak.tex') for information on how to write
+your own styles.
+
+ Eplain automatically reads the citations from the .aux file when
+your job starts.
+
+ If you don't want to see the messages about undefined citations, you
+can say `\xrefwarningfalse' before making any citations. Eplain
+automatically does this if the .aux file does not exist. You can
+restore the default by saying `\xrefwarningtrue'.
+
+ Here is a TeX input file that illustrates the various commands.
+
+ \input eplain % Reads the .aux file.
+ Two citations to Knuthian works:
+ \cite[note]{surreal,concrete-math}.
+ \beginsection{References.}\par % Title for the bibliography.
+ \bibliography{knuth} % Use knuth.bib for the labels.
+ \bibliographystyle{plain} % Number the references.

+ $ tex citex (produces undefined citation messages)
+ $ bibtex citex (read knuth.bib and citex.aux, write citex.bbl)
+ $ tex citex (read citex.bbl, still have undefined citations)

+
+4.3.1 Formatting citations
+--------------------------
+
+You may wish to change Eplain's formatting of citations; i.e., the
+result of your `\cite' commands. By default, the citation labels are
+printed one after another, separated by commas and enclosed in
+brackets, using the main text font. Some formats require other styles,
+such as superscripted labels. You can accomodate such formats by
+redefining the following macros.
+
+`\printcitestart'
+
+`\printcitefinish'
+ Eplain expands these macros at the begining and end of the list of
+ citations for each `\cite' command. By default, they produce a
+ `[' and `]', respectively.
+
+`\printbetweencitations'
+ If a `\cite' command has multiple citations, as in
+ `\cite{acp,texbook}', Eplain expands this macro in between each
+ pair of citations. By default, it produces a comma followed by a
+ space.
+
+`\printcitenote'
+ This macro takes one argument, which is the optional note to the
+ `\cite' command. If the `\cite' command had no note, this macro
+ isn't used. Otherwise, it should print the note. By default, the
+ note is preceded with a comma and a space.
+
+ Here is an example, showing you could produce citations as
+superscripted labels, with the optional notes in parentheses.
+
+ \def\printcitestart{\unskip $^\bgroup}
+ \def\printbetweencitations{,}
+ \def\printcitefinish{\egroup$}
+ \def\printcitenote#1{\hbox{\sevenrm\space (#1)}}

+
+4.3.2 Formatting bibliographies
+-------------------------------
+
+You may wish to change Eplain's formatting of the bibliography,
+especially with respect to the fonts that are used. Therefore, Eplain
+provides the following control sequences:
+
+`\biblabelwidth'
+ This control sequence represents a `\dimen' register, and its value
+ is the width of the widest label in the bibliography. Although it
+ is unlikely you will ever want to redefine it, you might want to
+ use it if you redefine `\biblabelprint', below.
+
+`\biblabelprint'
+ This macro takes one argument, the label to print. By default, the
+ label is put in a box of width `\biblabelwidth', and is followed by
+ an enspace. When you want to change the spacing around the
+ labels, this is the right macro to redefine.
+
+`\biblabelcontents'
+ This macro also takes one argument, the label to print. By
+ default, the label is printed using the font `\bblrm' (below), and
+ enclosed in brackets. When you want to change the appearance of
+ the label, but not the spacing around it, this is the right macro
+ to redefine.
+
+`\bblrm'
+ The default font used for printing the bibliography.
+
+`\bblem'
+ The font used for printing the titles and other "emphasized"
+ material.
+
+`\bblsc'
+ In some styles, authors' names are printed in a caps-and-small-caps
+ font. In those cases, this font is used.
+
+`\bblnewblock'
+ This is invoked between each of the parts of a bibliography entry.
+ The default is to leave some extra space between the parts; you
+ could redefine it to start each part on a new line (for example).
+ A part is simply a main element of the entry; for example, the
+ author is a part. (It was LaTeX that introduced the (misleading,
+ as far as I am concerned) term `block' for this.)
+
+`\biblabelextraspace'
+ Bibliography entries are typeset with a hanging indentation of
+ `\biblabelwidth' plus this. The default is `.5em', where the em
+ width is taken from the `\bblrm' font. If you want to change
+ this, you should do it inside `\bblhook'.
+
+`\bblhook'
+ This is expanded before reading the .bbl file. By default, it
+ does nothing. You could, for example, define it to set the
+ bibliography fonts, or produce the heading for the references. Two
+ spacing parameters must be changed inside `\bblhook': `\parskip',
+ which produces extra space between the items; and
+ `\biblabelextraspace', which is described above. (By the way,
+ `\hookappend' won't work with `\bblhook', despite the names. Just
+ use `\def'.)
+
+
+ If you are really desperate, you can also hand-edit the .bbl file
+that BibTeX produces to do anything you wish.

+
+4.4 Displays
+============
+
+By default, TeX centers displayed material. (Displayed material is
+just whatever you put between `$$''s--it's not necessarily
+mathematics.) Many layouts would be better served if the displayed
+material was left-justified. Therefore, Eplain provides the command
+`\leftdisplays', which indents displayed material by `\parindent' plus
+`\leftskip', plus `\leftdisplayindent'.
+
+ You can go back to centering displays with `\centereddisplays'. (It
+is usually poor typography to have both centered and left-justified
+displays in a single publication, though.)
+
+ `\leftdisplays' also changes the plain TeX commands that deal with
+alignments inside math displays, `\displaylines', `\eqalignno', and
+`\leqalignno', to produce left-justified text. You can still override
+this formatting by inserting `\hfill' glue, as explained in `The
+TeXbook'.
+
+* Menu:
+
+* Formatting displays:: General formatting of displays.
+
+
+File: eplain.info, Node: Formatting displays, Up: Displays
+
+4.4.1 Formatting displays
+-------------------------
+
+If you want some other kind of formatting, you can write a definition
+of your own, analogous to `\leftdisplays'. You need only make sure
+that `\leftdisplaysetup' is called at the beginning of every display
+(presumably by invoking it in TeX's `\everydisplay' parameter), and to
+define `\generaldisplay'.
+
+ `\leftdisplays' expands the old value of `\everydisplay' before
+calling `\leftdisplaysetup', so that any changes you have made to it
+won't be lost. That old token list as available as the value of the
+token register `\previouseverydisplay'.

+4.5 Time of day
+===============
+
+TeX provides the day, month, and year as numeric quantities (unless
+your TeX implementation is woefully deficient). Eplain provides some
+control sequences to make them a little more friendly to humans.
+
+ `\monthname' produces the name of the current month, abbreviated to
+three letters.
+
+ `\fullmonthname' produces the name of the current month,
+unabbreviated (in English).
+
+ `\timestring' produces the current time, as in `1:14 p.m.'
+
+ `\timestamp' produces the current date and time, as in `23 Apr 64
+1:14 p.m.'. (Except the spacing is slightly different.)
+
+ `\today' produces the current date, as in `23 April 1964'.
+
+
+File: eplain.info, Node: Lists, Next: Verbatim listing, Prev: Time of day, Up: User definitions
+
+4.6 Lists
+=========
+
+Many documents require lists of items, either numbered or simply
+enumerated. Plain TeX defines one macro to help with creating lists,
+`\item', but that is insufficient in many cases. Therefore, Eplain
+provides two pairs of commands:
+
+`\numberedlist ... \endnumberedlist'
+
+`\orderedlist ... \endorderedlist'
+ These commands (they are synonyms) produce a list with the items
+ numbered sequentially, starting from one. A nested `\numberedlist'
+ labels the items with lowercase letters, starting with `a'.
+ Another nested `\numberedlist' labels the items with roman
+ numerals. Yet more deeply nested numbered lists label items with
+ `*'.
+
+`\unorderedlist ... \endunorderedlist'
+ This produces a list with the items labelled with small black boxes
+ ("square bullets"). A nested `\unorderedlist' labels items with
+ em-dashes. Doubly (and deeper) nested unordered lists label items
+ with `*'s.
+
+
+ The two kinds of lists can be nested within each other, as well.
+
+ In both kinds of lists, you begin an item with `\li'. An item may
+continue for several paragraphs. Each item starts a paragraph.
+
+ You can give `\li' an optional argument, a cross-reference label.
+It's defined to be the "marker" for the current item. This is useful
+if the list items are numbered. You can produce the value of the label
+with `\xrefn'. *Note Cross-references::.
+
+ Eplain can create hypertext links for the markers produced by
+`\xrefn' pointing to the relevant list item (*note List hyperlinks::).
+
+ You can also say `\listcompact' right after `\numberedlist' or
+`\unorderedlist'. The items in the list will then not have any extra
+space between them (*note Formatting lists::). You might want to do
+this if the items in this particular list are short.
+
+ Here is an example:
+
+ \numberedlist\listcompact
+ \li The first item.
+ \li The second item.
+
+ The second paragraph of the second item.
+ \endnumberedlist
+
+* Menu:
+
+* Formatting lists:: Changing how the lists look.
+
+
+File: eplain.info, Node: Formatting lists, Up: Lists
+
+4.6.1 Formatting lists
+----------------------
+
+Several registers define the spacing associated with lists. It is
+likely that their default values won't suit your particular layout.
+
+`\abovelistskipamount, \belowlistskipamount'
+ The vertical glue inserted before and after every list,
+ respectively.
+
+`\interitemskipamount'
+ The vertical glue inserted before each item except the first.
+ `\listcompact' resets this to zero, as mentioned above.
+
+`\listleftindent, \listrightindent'
+ `\listrightindent' is the amount of space by which the list is
+ indented on the right; i.e., it is added to `\rightskip'.
+ `\listleftindent' is the amount of space, _relative to_
+ `\parindent', by which the list is indented on the left. Why treat
+ the two parameters differently? Because (a) it is more useful to
+ make the list indentation depend on the paragraph indentation;
+ (b) footnotes aren't formatted right if `\parindent' is reset to
+ zero.
+
+
+ The three vertical glues are inserted by macros, and preceded by
+penalties: `\abovelistskip' does `\vpenalty\abovelistpenalty' and then
+`\vskip\abovelistskip'. `\belowlistskip' and `\interitemskip' are
+analogous.
+
+ In addition, the macro `\listmarkerspace' is called to separate the
+item label from the item text. This is set to `\enspace' by default.
+
+ If you want to change the labels on the items, you can redefine these
+macros: `\numberedmarker' or `\unorderedmarker'. The following
+registers might be useful if you do:
+
+`\numberedlistdepth, \unorderedlistdepth'
+ These keep track of the depth of nesting of the two kinds of lists.
+
+`\itemnumber, \itemletter'
+ These keep track of the number of items that have been seen in the
+ current numbered list. They are both integer registers. The
+ difference is that `\itemnumber' starts at one, and `\itemletter'
+ starts at 97, i.e., lowercase `a'.
+
+
+ You can also redefine the control sequences that are used internally,
+if you want to do something radically different: `\beginlist' is
+invoked to begin both kinds of lists; `\printitem' is invoked to print
+the label (and space following the label) for each item; and `\endlist' is
+invoked to end both kinds of lists.

+
+4.7 Verbatim listing
+====================
+
+It is sometimes useful to include a file verbatim in your document; for
+example, part of a computer program. The `\listing' command is given
+one argument, a filename, and produces the contents of that file in
+your document. `\listing' expands `\listingfont' to set the current
+font. The default value of `\listingfont' is `\tt'.
+
+ You can take arbitrary actions before reading the file by defining
+the macro `\setuplistinghook'. This is expanded just before the file
+is input.
+
+ If you want to have line numbers on the output, you can say
+`\let\setuplistinghook = \linenumberedlisting'. The line numbers are
+stored in the count register `\lineno' while the file is being read.
+You can redefine the macro `\printlistinglineno' to change how they are
+printed.
+
+ Normally, the `\listing' command will add a final empty line at the
+end of the output, even if the file does not end in a newline. To
+suppress this final line, you can say `\let\setuplistinghook =
+\nolastlinelisting'. This also works with line numbers (say
+`\def\setuplistinghook{\linenumberedlisting \nolastlinelisting}'), but
+only if `\printlistinglineno' consists exclusively of boxes at the top
+level (i.e., any `\kern's or glue should be wrapped up in a box).
+
+ You can use the form feed control character (ASCII code 12, typed as
+`CTRL-L') in the file to force a page break in the output.
+
+ You can produce in-line verbatim text in your document with
+`\verbatim'. End the text with `|endverbatim'. If you need a `|' in
+the text, double it. If the first character of the verbatim text is a
+space, use `| '. (`| ' will work elsewhere in the argument, too, but
+isn't necessary.)
+
+ For example:
+
+ \verbatim| ||\#%&!|endverbatim
+
+produces ` |\#%&!'.
+
+ Line breaks and spaces in the verbatim text are preserved.
+
+ You can change the verbatim escape character from the default `|'
+with `\verbatimescapechar CHAR'; for example, this changes it to `@'.
+
+ \verbatimescapechar \@
+
+The backslash is not necessary in some cases, but is in others,
+depending on the catcode of the character. The argument to
+`\verbatimescapechar' is used as `\catcode `CHAR', so the exact rules
+follow that for `\catcode'.
+
+ Because `\verbatim' must change the category code of special
+characters, calling inside a macro definition of your own does not work
+properly. For example:
+
+ \def\mymacro{\verbatim &#%|endverbatim}% Doesn't work!
+
+To accomplish this, you must change the category codes yourself before
+making the macro definition. Perhaps `\uncatcodespecials' will help
+you (*note Category codes::).

+
+4.8 Contents
+============
+
+Producing a table of contents that is both useful and aesthetic is one
+of the most difficult design problems in any work. Naturally, Eplain
+does not pretend to solve the design problem. Collecting the raw data
+for a table of contents, however, is much the same across documents.
+Eplain uses an auxiliary file with extension `.toc' (and the same root
+name as your document) to save the information.
+
+* Menu:
+
+* Writing the .toc file::
+* Reading the .toc file::
+* Changing the .toc file's root name::
+* Alternative contents files::
+
+
+File: eplain.info, Node: Writing the .toc file, Next: Reading the .toc file, Up: Contents
+
+4.8.1 Writing the .toc file
+---------------------------
+
+To write an entry for the table of contents, you say
+`\writetocentry{PART}{TEXT}', where PART is the type of part this entry
+is, e.g., `chapter', and TEXT is the text of the title.
+`\writetocentry' puts an entry into the .toc file that looks like
+`\tocPARTentry{TEXT}{PAGE NUMBER}' (unless PART is an integer, see
+below). The TEXT is written unexpanded.
+
+ A related command, `\writenumberedtocentry', takes one additional
+argument, the first token of which is expanded at the point of the
+`\writenumberedtocentry', but the rest of the argument is not expanded.
+The usual application is when the parts of the document are numbered.
+On the other hand, the one-level expansion allows you to use the
+argument for other things as well (author's names in a proceedings,
+say), and not have accents or other control sequences expanded. The
+downside is that if you _want_ full expansion of the third argument,
+you don't get it--you must expand it yourself, before you call
+`\writenumberedtocentry'.
+
+ For example:
+
+ \writenumberedtocentry{chapter}{A $\sin$ wave}{\the\chapno}
+ \writetocentry{section}{A section title}
+
+Supposing `\the\chapno' expanded to `3' and that the `\write''s
+occurred on pages eight and nine, respectively, the above writes the
+following to the .toc file:
+
+ \tocchapterentry{A $\sin$ wave}{3}{8}
+ \tocsectionentry{A section title}{9}
+
+ A variation on `\writenumberedtocentry' is `\writenumberedtocline',
+differing only in the order of the parameters it takes and writes for
+the `\tocPARTentry' control sequences. To continue the previous
+example:
+
+ \writenumberedtocline{chapter}{\the\chapno}{A $\sin$ wave}
+
+writes the following to the .toc file:
+
+ \tocchapterentry{3}{A $\sin$ wave}{8}
+
+Such ordering of the parameters allows the `\tocPARTentry' macros to
+typeset the text of the entry without actually reading it as an
+argument. This is required for entries which need to change character
+catcodes, e.g., to produce verbatim text (*note Verbatim listing::).
+
+ Each of `\writetocentry', `\writenumberedtocentry' and
+`\writenumberedtocline' processes a numeric PART argument specially.
+If you pass PART expanding to an integer, these macros write into the
+.toc file an entry that starts with `\tocentry{PART}'. Thus, you can
+define a single `\tocentry' macro which formats all entries for a table
+of contents. To continue the previous examples:
+
+ \writenumberedtocentry{1}{A $\sin$ wave}{\the\chapno}
+ \writenumberedtocline{1}{\the\chapno}{A $\sin$ wave}
+ \writetocentry{2}{A section title}
+
+writes the following to the .toc file:
+
+ \tocentry{1}{A $\sin$ wave}{3}{8}
+ \tocentry{1}{3}{A $\sin$ wave}{8}
+ \tocentry{2}{A section title}{9}

+
+4.8.2 Reading the .toc file
+---------------------------
+
+You read the .toc file with the command `\readtocfile'. Naturally,
+whatever `\toc... entry' commands that were written to the file must be
+defined when `\readtocfile' is invoked. Eplain has minimal definitions
+for `\tocchapterentry', `\tocsectionentry', and `\tocsubsectionentry',
+just to prevent undefined control sequence errors in common cases.
+They aren't suitable for anything but preliminary proofs.
+
+ Each of `\writetocentry', `\writenumberedtocentry' and
+`\writenumberedtocline' opens the .toc file for writing, thereby
+deleting the information from the previous run. You should therefore
+arrange that `\readtocfile' be called _before_ the first call to a
+`\writetoc...' macro. `\readtocfile' does not itself delete the
+information from the .toc file, so that you can call it several times,
+e.g., to create both a short and normal table of contents. (To produce
+this in particular, define `\tocsectionentry' to produce nothing while
+you are reading .toc file for a short table of contents (*note Macro
+arguments::).)
+
+ On the other hand, if you don't want to rewrite the .toc file at
+all, perhaps because you are only running TeX on part of your
+manuscript, you can set `\rewritetocfilefalse'.
+
+
+File: eplain.info, Node: Changing the .toc file's root name, Next: Alternative contents files, Prev: Reading the .toc file, Up: Contents
+
+4.8.3 Changing the .toc file's root name
+----------------------------------------
+
+By default, the `.toc' file has the root `\jobname'. If your document
+has more than one contents--for example, if it is a collection of
+papers, some of which have their own contents--you can tell Eplain to
+use a different root name by defining the control sequence
+`\tocfilebasename'.
+
+ Note that `\writetocentry', `\writenumberedtocentry' and
+`\writenumberedtocline' will open the contents file for writing only at
+the first call, using the value of `\tocfilebasename' at that time.
+Changing the value of `\tocfilebasename' afterwards will not affect
+which file gets _written_, although it will affect which file gets
+_read_ by `\readcontentsfile'. In case you need to write several
+contents files from a single TeX job, use `\definecontentsfile' (*note
+Alternative contents files::).
+
+
+File: eplain.info, Node: Alternative contents files, Prev: Changing the .toc file's root name, Up: Contents
+
+4.8.4 Alternative contents files
+--------------------------------
+
+In addition to the usual table of contents, you may want to have a list
+of figures, list of tables, or other such contents-like list. You can do
+this with `\definecontentsfile{ABBREV}'. All of the above commands are
+actually a special case that Eplain predefines with
+
+ \definecontentsfile{toc}
+
+The ABBREV is used both for the file extension and in the control
+sequence names.

+
+4.9 Cross-references
+====================
+
+It is often useful to refer the reader to other parts of your document;
+but putting literal page, section, equation, or whatever numbers in the
+text is certainly a bad thing.
+
+ Eplain therefore provides commands for symbolic cross-references. It
+uses an auxiliary file with extension .aux (and the same root name as
+your document) to keep track of the information. Therefore, it takes
+two passes to get the cross-references right--one to write them out,
+and one to read them in. Eplain automatically reads the .aux file at
+the first reference; after reading it, Eplain reopens it for writing.
+
+ You can control whether or not Eplain warns you about undefined
+labels. *Note Citations::.
+
+ Labels in Eplain's cross-reference commands can use characters of
+category code eleven (letter), twelve (other), ten (space), three (math
+shift), four (alignment tab), seven (superscript), or eight (subscript).
+For example, `(a1 $&^_' is a valid label (assuming the category codes
+of plain TeX), but `%#\{' has no valid characters.
+
+ You can also do symbolic cross-references for bibliographic citations
+and list items. *Note Citations::, and *Note Lists::.
+
+ Eplain can create hypertext links for the cross-references (*note
+Cross-reference hyperlinks::).

+File: eplain.info, Node: Defining generic references, Next: Using generic references, Up: Cross-references
+
+4.9.1 Defining generic references
+---------------------------------
+
+Eplain provides the command `\definexref' for general cross-references.
+It takes three arguments: the name of the label (see section above for
+valid label names), the value of the label (which can be anything), and
+the "class" of the reference--whether it's a section, or theorem, or
+what. For example:
+
+ \definexref{sec-intro}{3.1}{section}
+
+Of course, the label value is usually generated by another macro using
+TeX count registers or some such.
+
+ `\definexref' doesn't actually define LABEL; instead, it writes out
+the definition to the .aux file, where Eplain will read it on the next
+TeX run.
+
+ The CLASS argument is used by the `\ref' and `\refs' commands. See
+the next section.
+
+
+File: eplain.info, Node: Using generic references, Prev: Defining generic references, Up: Cross-references
+
+4.9.2 Using generic references
+------------------------------
+
+To retrieve the value of the label defined via `\definexref' (see the
+previous section), Eplain provides the following macros:
+
+`\refn{LABEL}'
+
+`\xrefn{LABEL}'
+ `\refn' and `\xrefn' (they are synonyms) produce the bare
+ definition of LABEL. If LABEL isn't defined, issue a warning, and
+ produce LABEL itself instead, in typewriter. (The warning isn't
+ given if `\xrefwarningfalse'.)
+
+`\ref{LABEL}'
+ Given the class C for LABEL (see the description of `\definexref'
+ in the previous section), expand the control sequence `\C word'
+ (if it's defined) followed by a tie. Then call `\refn' on LABEL.
+ (Example below.)
+
+`\refs{LABEL}'
+ Like `\ref', but append the letter `s' to the `\...word'.
+
+
+ The purpose of the `\...word' macro is to produce the word `Section'
+or `Figure' or whatever that usually precedes the actual reference
+number.
+
+ Here is an example:
+
+ \def\sectionword{Section}
+ \definexref{sec-intro}{3.1}{section}
+ \definexref{sec-next}{3.2}{section}
+ See \refs{sec-intro} and \refn{sec-next} ...
+
+This produces `See Sections 3.1 and 3.2 ...'

+
+4.10 Page references
+====================
+
+Eplain provides two commands for handling references to page numbers,
+one for definition and one for use.
+
+`\xrdef{LABEL}'
+ Define LABEL to be the current page number. This produces no
+ printed output, and ignores following spaces.
+
+`\xref{LABEL}'
+ Produce the text `p. PAGENO', which is the usual form for
+ cross-references. The PAGENO is actually LABEL's definition; if
+ LABEL isn't defined, the text of the label itself is printed. The
+ `p. ' prefix is defined by `\xrefpageword'. Its default
+ definition is `p.\thinspace'.
+
+
+ Eplain can create hypertext links for the page references (*note
+Page reference hyperlinks::).

+Instead of referring to pages, it's most useful if equation labels
+refer to equation numbers. Therefore, Eplain reserves a `\count'
+register, `\eqnumber', for the current equation number, and increments
+it at each numbered equation.
+
+ Here are the commands to define equation labels and then refer to
+them:
+
+`\eqdef{LABEL}'
+ This defines LABEL to be the current value of `\eqnumber', and, if
+ the current context is not inner, then produces a `\eqno' command.
+ (The condition makes it possible to use `\eqdef' in an
+ `\eqalignno' construction, for example.) The text of the equation
+ number is produced using `\eqprint'. *Note Formatting equation
+ references::.
+
+ If LABEL is empty, you still get an equation number (although
+ naturally you can't reliably refer to it). This is useful if you
+ want to put numbers on all equations in your document, and you
+ don't want to think up unique labels.
+
+ To refer to the last equation with the empty label, you just use
+ the empty label in one of the equation reference macros (see
+ below). This can be handy when you want to refer to an equation
+ shortly after its definition, say, in the sentence following the
+ displayed equation, and do not intend to refer to the equation
+ later. But use this trick with extreme caution: if later you
+ change the text and insert another empty definition between the
+ original definition and the reference, the reference will start to
+ refer to the new empty-labeled equation.
+
+`\eqdefn{LABEL}'
+ This is like `\eqdef', except it always omits the `\eqno' command.
+ It can therefore be used in places where `\eqdef' can't; for
+ example, in a non-displayed equation. The text of the equation
+ number is not produced, so you can also use it in the (admittedly
+ unusual) circumstance when you want to define an equation label
+ but not print that label.
+
+`\eqref{LABEL}'
+ This produces a formatted reference to LABEL. If LABEL is
+ undefined (perhaps because it is a forward reference), it just
+ produces the text of the label itself. Otherwise, it calls
+ `\eqprint'.
+
+`\eqrefn{LABEL}'
+ This produces the cross-reference text for LABEL. That is, it is
+ like `\eqref', except it doesn't call `\eqprint'.
+
+
+ Equation labels can contain the same characters that are valid in
+general cross-references.
+
+ Eplain can create hypertext links for the equation references (*note
+Equation reference hyperlinks::).

+
+4.11.1 Formatting equation references
+-------------------------------------
+
+Both defining an equation label and referring to it should usually
+produce output. This output is produced with the `\eqprint' macro,
+which takes one argument, the equation number being defined or referred
+to. By default, this just produces `(NUMBER)', where NUMBER is the
+equation number. To produce the equation number in a different font,
+or with different surrounding symbols, or whatever, you can redefine
+`\eqprint'. For example, the following definition would print all
+equation numbers in italics. (The extra braces define a group, to keep
+the font change from affecting surrounding text.)
+
+ \def\eqprint#1{{\it (#1)}}
+
+ In addition to changing the formatting of equation numbers, you
+might want to add more structure to the equation number; for example,
+you might want to include the chapter number, to get equation numbers
+like `(1.2)'. To achieve this, you redefine `\eqconstruct'. For
+example:
+
+ \def\eqconstruct#1{\the\chapternumber.#1}
+
+(If you are keeping the chapter number in a count register named
+`\chapternumber', naturally.)
+
+ The reason for having both `\eqconstruct' and `\eqprint' may not be
+immediately apparent. The difference is that `\eqconstruct' affects
+the text that cross-reference label is defined to be, while `\eqprint'
+affects only what is typeset on the page. The example just below might
+help.
+
+ Usually, you want equation labels to refer to equation numbers. But
+sometimes you might want a more complicated text. For example, you
+might have an equation `(1)', and then have a variation several pages
+later which you want to refer to as `(1*)'.
+
+ Therefore, Eplain allows you to give an optional argument (i.e.,
+arbitrary text in square brackets) before the cross-reference label to
+\eqdef. Then, when you refer to the equation, that text is produced.
+Here's how to get the example just mentioned:
+
+ $$...\eqdef{a-eq}$$
+ ...
+ $$...\eqdef[\eqrefn{a-eq}*]{a-eq-var}$$
+ In \eqref{a-eq-var}, we expand on \eqref{a-eq}, ...
+
+ We use `\eqrefn' in the cross-reference text, not `\eqref', so that
+`\eqprint' is called only once.
+

+
+4.11.2 Subequation references
+-----------------------------
+
+Eplain also provides for one level of substructure for equations. That
+is, you might want to define a related group of equations with numbers
+like `2.1' and `2.2', and then be able to refer to the group as a whole:
+"... in the system of equations (2)...".
+
+ The commands to do this are `\eqsubdef' and `\eqsubdefn'. They take
+one LABEL argument like their counterparts above, and generally behave
+in the same way. The difference is in how they construct the equation
+number: instead of using just `\eqnumber', they also use another
+counter, `\subeqnumber'. This counter is advanced by one at every
+`\eqsubdef' or `\eqsubdefn', and reset to zero at every `\eqdef' or
+`\eqdefn'.
+
+ You use `\eqref' to refer to subequations as well as main equations.
+
+ To put the two together to construct the text that the label will
+produce, they use a macro `\eqsubreftext'. This macros takes two
+arguments, the "main" equation number (which, because the equation
+label can be defined as arbitrary text, as described in the previous
+section, might be anything at all) and the "sub" equation number (which
+is always just a number). Eplain's default definition just puts a
+period between them:
+
+ \def\eqsubreftext#1#2{#1.#2}%
+
+You can redefine `\eqsubreftext' to print however you like. For
+example, this definition makes the labels print as `2a', `2b', and so
+on.
+
+ \newcount\subref
+ \def\eqsubreftext#1#2{%
+ \subref = #2 % The space stops a <number>.
+ \advance\subref by 96 % `a' is character code 97.
+ #1\char\subref
+ }
+
+Sadly, we must define a new count register, `\subref', instead of using
+the scratch count register `\count255', because `#1' might include
+other macro calls which use `\count255'.

+
+4.12 Indexing
+=============
+
+Eplain provides support for generating raw material for an index, and
+for typesetting a sorted index. A separate program must do the actual
+collection and sorting of terms, because TeX itself has no support for
+sorting.
+
+ Eplain can create hypertext links pointing from the index to the
+index terms (*note Index hyperlinks::).
+
+ Eplain's indexing commands were designed to work with the program
+MakeIndex, available from CTAN hosts in
+`tex-archive/indexing/makeindex'; MakeIndex is also commonly included
+in prepackaged TeX distributions. It is beyond the scope of this
+manual to explain how to run MakeIndex, and all of its many options.
+See `http://www.ctan.org/tex-archive/indexing/makeindex'.
+
+ The basic strategy for indexing works like this:
+
+ 1. For a document `foo.tex', Eplain's indexing commands (e.g.,
+ `\idx'; see the section `Indexing terms' below) write the raw index
+ material to `foo.idx'.
+
+ 2. MakeIndex reads `foo.idx', collects and sorts the index, and
+ writes the result to `foo.ind'.
+
+ 3. Eplain reads and typesets `foo.ind' on a subsequent run of TeX.
+ See the section `Typesetting an index' below.
+
+
+The `texi2dvi' program can help you automate this process (*note
+Invoking Eplain::).
+
+ If your document needs more than one index, each must have its own
+file. Therefore, Eplain provides the command `\defineindex', which
+takes an argument that is a single letter, which replaces `i' in the
+filenames and in the indexing command names described below. For
+example,
+
+ \defineindex{m}
+
+defines the command `\mdx' to write to the file `foo.mdx'. Eplain
+simply does `\defineindex{i}' to define the default commands.

+
+4.12.1 Indexing terms
+---------------------
+
+Indexing commands in Eplain come in pairs: one command that only writes
+the index entry to the `.idx' file (see above section), and one that
+also typesets the term being indexed. The former always starts with `s'
+(for "silent"). In either case, the name always includes `Idx', where I
+is the index letter, also described above. Eplain defines the index `i'
+itself, so that's what we'll use in the names below.
+
+ The silent form of the commands take a subterm as a trailing optional
+argument. For example, `\sidx{truth}[definition of]' on page 75 makes
+an index entry that will eventually be typeset (by default) as
+
+ truth
+ definition of, 75
+
+ Also, the silent commands ignore trailing spaces. The non-silent
+ones do not.

+File: eplain.info, Node: Indexing commands, Next: Modifying index entries, Up: Indexing terms
+
+4.12.1.1 Indexing commands
+..........................
+
+Here are the commands.
+
+ * `\sidx{TERM}[SUBTERM]' makes an index entry for TERM, optionally
+ with subterm SUBTERM. `\idx{TERM}' also produces TERM as output.
+ Example:
+
+ \sidx{truth}[beauty of]
+ The beauty of truth is \idx{death}.
+
+ Subterms at the second and further levels can also be specified in
+ SUBTERM, using the `\idxsubentryseparator' character to separate
+ them. This character is by default `!'.
+
+ * `\sidxname{FIRST M.}{VON LAST}[SUBTERM]' makes an index entry for
+ `VON LAST, FIRST M.'. You can change the `, ' by redefining
+ `\idxnameseparator'. `\idxname{FIRST M.}{VON LAST}' also produces
+ FIRST M. VON LAST as output. (These commands are useful special
+ cases of `\idx' and `\sidx'.) Example:
+
+ \sidxname{Richard}{Stark}
+ \idxname{Donald}{Westlake} has written many kinds of novels, under
+ almost as many names.
+
+ * `\sidxmarked\CS{TERM}[SUBTERM]' makes an index entry for
+ `TERM[SUBTERM]', but TERM will be put in the index as `\CS{term}',
+ but still sorted as just TERM. `\idxmarked\CS{TERM}' also typesets
+ `\CS{term}'. This provides for the usual ways of changing the
+ typesetting of index entries. Example:
+
+ \def\article#1{``#1''}
+ \sidxmarked\article{Miss Elsa and Aunt Sophie}
+ Peter Drucker's \idxmarked\article{The Polanyis} is a remarkable
+ essay about a remarkable family.
+
+ * `\sidxsubmarked{TERM}\CS{subterm}' makes an index entry for TERM,
+ SUBTERM as usual, but also puts SUBTERM in the index as
+ `\CS{term}'. `\idxsubmarked{TERM}\CS{subterm}' also typesets
+ `TERM \CS{subterm}', in the unlikely event that your syntax is
+ convoluted enough to make this useful. Example:
+
+ \def\title#1{{\sl #1}}
+ \sidxsubmarked{Anderson, Laurie}\title{Strange Angels}
+ The \idxsubmarked{Anderson}\title{Carmen} is a strange twist.
+
+
+ The commands above rely on MakeIndex's feature for separating
+sorting of an index entry's from its typesetting. You can use this
+directly by specifying an index entry as `SORT@TYPESET'. For example:
+
+ \sidx{Ap-weight@$A_\pi$-weight}
+
+will sort as `Ap-weight', but print with the proper math. The `@' here
+is MakeIndex's default character for this purpose. See
+`http://www.ctan.org/tex-archive/indexing/makeindex'. To make an index
+entry with an `@' in it, you have to escape it with a backslash; Eplain
+provides no macros for doing this.
+
+ After any index command, Eplain runs `\hookaction{afterindexterm}'.
+Because the index commands always add a whatsit item to the current
+list, you may wish to preserve a penalty or space past the new item.
+For example, given a conditional `\if@aftersctnhead' set true when
+you're at a section heading, you could do:
+
+ \hookaction{afterindexterm}{\if@aftersctnhead \nobreak \fi}

+
+4.12.1.2 Modifying index entries
+................................
+
+All the index commands described in the previous section take an initial
+optional argument before the index term, which modify the index entry's
+meaning in various ways. You can specify only one of the following in
+any given command, except that `begin' and `end' can be specified
+together with `pagemarkup=CS' (separate them with a comma without a
+following space, like this: `[begin,pagemarkup=defn]').
+
+ These work via MakeIndex's "encapsulation" feature. *Note
+Customizing indexing::, if you're not using the default characters for
+the MakeIndex operators. The other optional argument (specifying a
+subterm) is independent of these.
+
+ Here are the possibilities:
+
+`begin'
+`end'
+ These mark an index entry as the beginning or end of a range. The
+ index entries must match exactly for MakeIndex to recognize them.
+ Example:
+
+ \sidx[begin]{future}[Cohen, Leonard]
+ ...
+ \sidx[end]{future}[Cohen, Leonard]
+
+ will typeset as something like
+
+ future,
+ Cohen, Leonard, 65-94
+
+`see'
+ This marks an index entry as pointing to another; the real index
+ term is an additional (non-optional) argument to the command. Thus
+ you can anticipate a term readers may wish to look up, yet which
+ you have decided not to index. Example:
+
+ \sidx[see]{analysis}[archetypal]{archetypal criticism}
+
+ becomes
+
+ analysis,
+ archetypal, see archetypal criticism
+
+`seealso'
+ Similar to `see' (the previous item), but also allows for normal
+ index entries of the referencing term. Example:
+
+ \sidx[seealso]{archetypal criticism}[elements of]{dichotomies}
+
+ becomes
+
+ archetypal criticism,
+ elements of, 75, 97, 114, see also dichotomies
+
+ (Aside for the academically curious: The archetypally critical
+ book I took these dichotomous examples from is Laurence Berman's
+ `The Musical Image', which I happened to co-design and typeset.)
+
+`pagemarkup=CS'
+ This puts `\CS' before the page number in the typeset index, thus
+ allowing you to underline definitive entries, italicize examples,
+ and the like. You do _not_ precede the control sequence CS with a
+ backslash. (That just leads to expansive difficulties.) Naturally
+ it is up to you to define the control sequences you want to use.
+ Example:
+
+ \def\defn#1{{\sl #1}}
+ \sidx[pagemarkeup=defn]{indexing}
+
+ becomes something like
+
+ indexing, `\defn{75}'
+
+
+
+File: eplain.info, Node: Index entries with special characters, Next: Proofing index terms, Prev: Modifying index entries, Up: Indexing terms
+
+4.12.1.3 Index entries with special characters
+..............................................
+
+Indexing terms with special characters can become quite cumbersome
+because you have to keep both TeX and MakeIndex happy at the same time.
+For example, while `!' has no special meaning for TeX, it is a
+subentry separator for MakeIndex, therefore you'd have to escape
+occurrences of literal `!' in index terms. Things get even more
+interesting with characters which are special in both TeX and MakeIndex.
+
+ This in turn has some implications for the non-silent forms of the
+indexing commands (*note Indexing terms::), since TeX and MakeIndex use
+different conventions for escaping characters. For example, this will
+not typeset the exclamation point correctly within the text, while it
+will come out right inside the index, after MakeIndex strips the
+quoting character (`"'):
+
+ \idx{"!}
+
+This would have to be rewritten using the silent command:
+
+ !\sidx{"!}
+
+In general, it is a good idea to eschew the non-silent commands
+whenever index term contains anything unusual.
+
+ To understand this keep in mind that indexing commands read the terms
+verbatim so that the terms can embed almost any character, and that's
+what gets written into the `.idx' file. The non-silent forms then
+typeset the term by rescanning the verbatim copy, therefore for the
+non-silent commands the term, besides being a valid MakeIndex input,
+must also represent a valid TeX input. The silent commands don't have
+this restriction--their terms only need to become valid TeX input
+_after_ MakeIndex processes the `.idx' file and writes the `.ind' file.
+This is what makes the non-silent commands less powerful and more
+troublesome when dealing with special characters.
+
+ Here's an example showing that terms for the silent commands can
+contain almost any character:
+
+ \sidx[see]{comments}[with %@with \verbatim %"|endverbatim]
+ {commenting with \verbatim %"|endverbatim}
+
+We didn't have to escape `%' in the sort string for MakeIndex, while we
+had to put it inside the verbatim environment (*note Verbatim
+listing::) in the part which MakeIndex will pass back to TeX. Also, we
+had to escape the `|' character because it is special for MakeIndex.
+If you have trouble understanding the reasons for the different types
+of escaping used, it is best to examine the `.idx' and `.ind' files
+resulting from processing the above input.
+
+ As was mentioned, index terms can embed "almost any character", so
+now we'll describe the exceptions.
+
+ The following characters are reset to their usual meanings because
+they are not useful verbatim: multiple consequent spaces are converted
+into a single space; ASCII tab characters are treated as spaces; ASCII
+return is treated as end-of-line (this means, among other things, that
+long terms can be broken across several lines).
+
+ You have to be careful with the begin- and end-group characters (`{'
+and `}' by default). If they are matched, you don't have to do
+anything special. For example:
+
+ \sidx {braces {, }@braces
+ \verbatim {"|endverbatim, \verbatim }"|endverbatim}
+
+However, if they are not matched you have two problems on hand. The
+first one is TeX--you have to instruct TeX to use something else as
+begin- and/or end-group characters. Eplain provides an easy way to do
+this: just define `\idxargopen' and/or `\idxargclose' to the begin-
+and end-group characters you are going to use with indexing macros, and
+use braces inside index terms without any restrictions. Here's an
+example:
+
+ \def\idxargopen{`\<}
+ \def\idxargclose{`\>}
+ \sidx <left brace "{@left brace \verbatim "{"|endverbatim>
+
+In this example we've also dealt with the second problem--braces are
+MakeIndex's grouping characters as well (by default), so we have
+escaped unmatched braces with `"'.
+
+ And the final note: if you need a subentry containing brackets (`['
+and `]'), avoid the optional argument of `\sidx' and friends, and use
+instead MakeIndex's subentry separator to create the subentry with the
+brackets in it:
+
+ \sidx{entry!subentry with a bracket [}
+

+
+4.12.1.4 Proofing index terms
+.............................
+
+As you are reading through a manuscript, it is helpful to see what terms
+have been indexed, so you can add others, catch miscellaneous errors,
+etc. (Speaking from bitter experience, I can say it is extremely
+error-prone to leave all indexing to the end of the writing, since it
+involves adding many TeX commands to the source files.)
+
+ So Eplain puts index terms in the margin of each page, if you set
+`\indexproofingtrue'. It is `false' by default. The terms are typeset
+by the macro `\indexproofterm', which takes a single argument, the term
+to be typeset. Eplain's definition of `\indexproofterm' just puts it
+into an `\hbox', first doing `\indexprooffont', which Eplain defines to
+select the font `cmtt8'. With this definition long terms run off the
+page, but since this is just for proofreading anyway, it seems
+acceptable.
+
+ On the other hand, we certainly don't want the index term to run into
+the text of the page, so Eplain uses the right-hand side of the page
+rather than the left-hand page (assuming a language read left to right
+here). So `\ifodd\pageno', Eplain kerns by `\outsidemargin', otherwise
+by `\insidemargin'. If those macros are undefined, `\indexsetmargins'
+defines them to be one inch plus `\hoffset'.
+
+ To get the proofing index entries on the proper page, Eplain defines
+a new insertion class `\@indexproof'. To unbox any index proofing
+material, Eplain redefines `\makeheadline' to call `\indexproofunbox'
+before the original `\makeheadline'. Thus, if you have your own output
+routine, that redefines or doesn't use `\makeheadline', it's up to you
+to call `\indexproofunbox' at the appropriate time.
+
+
+File: eplain.info, Node: Typesetting an index, Next: Customizing indexing, Prev: Indexing terms, Up: Indexing
+
+4.12.2 Typesetting an index
+---------------------------
+
+The command `\readindexfile{i}' reads and typesets the `.ind' file that
+MakeIndex outputs (from the `.idx' file which the indexing commands in
+the previous sections write). Eplain defines a number of commands that
+support the default MakeIndex output.
+
+ More precisely, `\readindexfile' reads
+`\indexfilebasename.INDEX-LETTERnd', where the INDEX-LETTER is the
+argument. `\indexfilebasename' is `\jobname' by default, but if you
+have different indexes in different parts of a book, you may wish to
+change it, just as with bibliographies (*note Citations::).
+
+ MakeIndex was designed to work with LaTeX; therefore, by default the
+`.ind' file starts with `\begin{theindex}' and ends with
+`\end{theindex}'. If no `\begin' has been defined, Eplain defines one
+to ignore its argument and set up for typesetting the index (see
+below), and also defines a `\end' to ignore its argument. (In a group,
+naturally, since there is a primitive `\end').
+
+ Eplain calls `\indexfonts', sets `\parindent = 0pt', and does
+`\doublecolumns' (*note Multiple columns::) at the `\begin{theindex}'.
+`\indexfonts' does nothing by default; it's just there for you to
+override. (Indexes are usually typeset in smaller type than the main
+text.)
+
+ It ends the setup with `\hookrun{beginindex}', so you can override
+anything you like in that hook (*note Hooks::). For example:
+
+ \hookaction{beginindex}{\triplecolumns}
+
+ MakeIndex turns each main index entry into an `\item', subentries
+into `\subitem', and subsubentries into `\subsubitem'. By default, the
+first line of main entries are not indented, and subentries are
+indented 1em per level. Main entries are preceded by a `\vskip' of
+`\aboveitemskipamount', `0pt plus2pt' by default. Page breaks are
+encouraged before main entries (`\penalty -100'), but prohibited
+afterwards--Eplain has no provision for "continued" index entries.
+
+ All levels do the following:
+
+ \hangindent = 1em
+ \raggedright
+ \hyphenpenalty = 10000
+
+ Each entry ends with `\hookrun{indexitem}', so you can change any of
+this. For example, to increase the allowable rag:
+
+ \hookaction{indexitem}{\advance\rightskip by 2em}
+
+ Finally, MakeIndex outputs `\indexspace' between each group of
+entries in the `.ind' file. Eplain makes this equivalent to `\bigbreak'.
+
+
+File: eplain.info, Node: Customizing indexing, Prev: Typesetting an index, Up: Indexing
+
+4.12.3 Customizing indexing
+---------------------------
+
+By default, MakeIndex outputs `, ' after each term in the index. To
+change this, you can add the following to your MakeIndex style (`.ist')
+file:
+
+ delim_0 "\\afterindexterm "
+ delim_1 "\\afterindexterm "
+ delim_2 "\\afterindexterm "
+
+Eplain makes `\afterindexterm' equivalent to `\quad'.
+
+ You can also change the keywords Eplain recognizes (*note Modifying
+index entries::):
+
+`\idxrangebeginword'
+ `begin'
+
+`\idxrangeendword'
+ `end'
+
+`\idxseecmdword'
+ `see'
+
+`\idxseealsocmdword'
+ `seealso'
+
+
+ You can also change the magic characters Eplain puts into the `.idx'
+file, in case you've changed them in the `.ist' file:
+
+`\idxsubentryseparator'
+ `!'
+
+`\idxencapoperator'
+ `|'
+
+`\idxbeginrangemark'
+ `('
+
+`\idxendrangemark'
+ `)'
+
+
+ There is no macro for the `actual' (`@' by default) character,
+because it's impossible to make it expand properly.
+
+ You can change the (imaginary) page number that "see also" entries
+sort as by redefining `\idxmaxpagenum'. This is 99999 by default, which
+is one digit too many for old versions of MakeIndex.
+
+ The words output by Eplain for "see" and "see also" index entries
+are defined by `\indexseeword' and `\indexseealsowords' respectively.
+You can change the typeface used for these words by redefining
+`\seevariant'. And finally, the macros `\indexsee' and `\indexseealso'
+actually produce the "see ..." entries, so you can redefine them if you
+want something entirely different. If you do redefine them, make them
+take two parameters, the term being referenced and the `\idxmaxpagenum'
+(the latter should normally be ignored). See the example below.
+
+ Unfortunately, it is impossible to reliably control the commas
+produced by MakeIndex in front of "see ..." entries in the `.ind' file,
+either at MakeIndex level or at Eplain level. However, the `sed'
+script contained in `trimsee' distributed with Eplain in the `util'
+directory can be used to filter out these commas from the output of
+MakeIndex. For example, suppose you want the following style for your
+"see ..." entries:
+
+ analysis,
+ archetypal (see archetypal criticism)
+ archetypal criticism,
+ elements of, 75, 97, 114 (see also dichotomies)
+
+You would need to redefine these macros in your TeX file:
+
+ \def\indexsee#1#2{({\seevariant \indexseeword\/ }#1)}
+ \def\indexseealso#1#2{({\seevariant \indexseealsowords\/ }#1)}
+
+and then filter out the commas in front of the "see ..." entries by
+running the following command to produce the `.ind' file (assuming the
+name of the `.idx' file is `myfile.idx' and the `trimsee' script is
+placed in the current directory):
+
+ prompt$ cat myfile.idx | makeindex | ./trimsee > myfile.ind
+
+ By default, `trimsee' uses default page list separators and default
+"see ..." command names. If you set up MakeIndex to use different page
+list separator or change the names of `\indexsee' and `\indexseealso'
+commands, it is possible to adjust the `trimsee' script through its
+command line options, which are the following:
+
+`-i IS'
+ Use IS as a regular expression matching separator before "see ..."
+ commands in the input (default: `, \+').
+
+`-o OS'
+ Use OS as a separator to replace IS before "see ..." commands
+ (default: ` ').
+
+`-s SEE'
+ Use SEE as a regular expression matching "see ..." commands
+ (default: `\\indexsee').
+
+`-h'
+`--help'
+ Print a usage message.
+
+`-v'
+`--version'
+ Print version.
+
+ `trimsee' reads input from the standard input, and directs its
+output to the standard output.

+4.13 Justification
+==================
+
+Eplain defines three commands to conveniently justify multiple lines of
+text: `\flushright', `\flushleft', and `\center'.
+
+ They all work in the same way; let's take `\center' as the example.
+To start centering lines, you say `\center' inside a group; to stop,
+you end the group. Between the two commands, each end-of-line in the
+input file also starts a new line in the output file.
+
+ The entire block of text is broken into paragraphs at blank lines,
+so all the TeX paragraph-shaping parameters apply in the usual way.
+This is convenient, but it implies something else that isn't so
+convenient: changes to any linespacing parameters, such as
+`\baselineskip', will have _no effect_ on the paragraph in which they
+are changed. TeX does not handle linespacing changes within a
+paragraph (because it doesn't know where the line breaks are until the
+end of the paragraph).
+
+ The space between paragraphs is by default one blank line's worth.
+You can adjust this space by assigning to `\blanklineskipamount'; this
+(vertical) glue is inserted after each blank line.
+
+ Here is an example:
+
+ {\center First line.
+
+ Second line, with a blank line before.
+ }
+
+This produces:
+
+ First line.
+
+ Second line, with a blank line before.
+
+ You may wish to use the justification macros inside of your own
+macros. Just be sure to put them in a group. For example, here is how
+a title macro might be defined:
+
+ \def\title{\begingroup\titlefont\center}
+ \def\endtitle{\endgroup}
+
+
+File: eplain.info, Node: Tables, Next: Margins, Prev: Justification, Up: User definitions
+
+4.14 Tables
+===========
+
+Eplain provides a single command, `\makecolumns', to make generating
+one particular kind of table easier. More ambitious macro packages
+might be helpful to you for more difficult applications. The files
+`ruled.tex' and `TXSruled.tex', available from
+`http://www.ctan.org/tex-archive/macros/texsis', is the only one I know
+of.
+
+ Many tables are homogenous, i.e., all the entries are semantically
+the same. The arrangement into columns is to save space on the page,
+not to encode different meanings. In this kind of the table, it is
+useful to have the column breaks chosen automatically, so that you can
+add or delete entries without worrying about the column breaks.
+
+ `\makecolumns' takes two arguments: the number of entries in the
+table, and the number of columns to break them into. As you can see
+from the example below, the first argument is delimited by a slash, and
+the second by a colon and a space (or end-of-line). The entries for the
+table then follow, one per line (not including the line with the
+`\makecolumns' command itself).
+
+ `\parindent' defines the space to the left of the table. `\hsize'
+defines the width of the table. So you can adjust the position of the
+table on the page by assignments to these parameters, probably inside a
+group.
+
+ You can also control the penalty at a page break before the
+`\makecolumns' by setting the parameter `\abovecolumnspenalty'. Usually,
+the table is preceded by some explanatory text. You wouldn't want a
+page break to occur after the text and before the table, so Eplain sets
+it to `10000'. But if the table produced by `\makecolumns' is standing
+on its own, `\abovecolumnspenalty' should be decreased.
+
+ If you happen to give `\makecolumns' a smaller number of entries
+than you really have, some text beyond the (intended) end of the table
+will be incorporated into the table, probably producing an error
+message, or at least some strange looking entries. And if you give
+`\makecolumns' a larger number of entries than you really have, some of
+the entries will be typeset as straight text, probably also looking
+somewhat out of place.
+
+ Here is an example:
+
+ % Arrange 6 entries into 2 columns:
+ \makecolumns 6/2: % This line doesn't have an entry.
+ one
+ two
+ three
+ four
+ five
+ six
+ Text after the table.
+
+This produces `one', `two', and `three' in the first column, and
+`four', `five', and `six' in the second.

+4.15 Margins
+============
+
+TeX's primitives describe the type area in terms of an offset from the
+upper left corner, and the width and height of the type. Some people
+prefer to think in terms of the "margins" at the top, bottom, left, and
+right of the page, and most composition systems other than TeX conceive
+of the page laid out in this way. Therefore, Eplain provides commands
+to directly assign and increment the margins.
+
+`\topmargin = DIMEN'
+`\bottommargin = DIMEN'
+`\leftmargin = DIMEN'
+
+`\rightmargin = DIMEN'
+ These commands set the specified margin to the DIMEN given. The
+ `=' and the spaces around it are optional. The control sequences
+ here are not TeX registers, despite appearances; therefore,
+ commands like `\showthe\topmargin' will not do what you expect.
+
+`\advancetopmargin by DIMEN'
+`\advancebottommargin by DIMEN'
+`\advanceleftmargin by DIMEN'
+
+`\advancerightmargin by DIMEN'
+ These commands change the specified margin by the DIMEN given.
+
+ Regardless of whether you use the assignment or the advance commands,
+Eplain always changes the type area in response, not the other margins.
+For example, when TeX starts, the left and right margins are both one
+inch. If you then say `\leftmargin = 2in', the right margin will
+remain at one inch, and the width of the lines (i.e., `\hsize') will
+decrease by one inch.
+
+ When you use any of these commands, Eplain computes the old value of
+the particular margin, by how much you want to change it, and then
+resets the values of TeX's primitive parameters to correspond.
+Unfortunately, Eplain cannot compute the right or bottom margin without
+help: you must tell it the full width and height of the final output
+page. It defines two new parameters for this:
+
+`\paperheight'
+ The height of the output page; default is 11truein.
+
+`\paperwidth'
+ The width of the output page; default is 8.5truein.
+
+ If your output page has different dimensions than this, you must
+reassign to these parameters, as in
+
+ \paperheight = 11truein
+ \paperwidth = 17truein
+
+
+File: eplain.info, Node: Multiple columns, Next: Footnotes, Prev: Margins, Up: User definitions
+
+4.16 Multiple columns
+=====================
+
+Eplain provides for double, triple, and quadruple column output: say
+`\doublecolumns', `\triplecolumns', or `\quadcolumns', and from that
+point on, the manuscript will be set in columns. To go back to one
+column, say `\singlecolumn'.
+
+ You may need to invoke `\singlecolumn' to balance the columns on the
+last page of output.
+
+ To do a "column eject", i.e., move to the top of the next column, do
+`\columnfill'. This does not actually force an eject, however: it
+merely inserts a kern of size `\@normalvsize' minus `\pagetotal'
+(`\@normalvsize' being the usual height of the page; to implement
+multicolumns, Eplain multiplies `\vsize' itself by the number of
+columns). In most circumstances, a column break will be forced after
+this kern (during the column splitting operation when the whole page is
+output), as desired.
+
+ The columns are separated by the value of the dimen parameter
+`\gutter'. Default value is two picas. If you want to add vertical
+material between the columns, use `\gutterbox'. For example, to put a
+vertical line between columns, define `\gutterbox' as
+
+ \def\gutterbox{\vbox to \dimen0{\vfil\hbox{\vrule height\dimen0}\vfil}}%
+
+The dimension counter `\dimen0' contains the height of the column.
+
+ All the `\...columns' macros insert the value of the glue parameter
+`\abovecolumnskip' before the multicolumn text, and the value of the
+glue parameter `\belowcolumnskip' after it. The default value for both
+of these parameters is `\bigskipamount', i.e., one linespace in plain
+TeX.
+
+ The macros take into account only the insertion classes defined by
+plain TeX; namely, footnotes and `\topinsert's. If you have additional
+insertion classes, you will need to change the implementation.
+
+ Also, Eplain makes insertions the full page width. There is no
+provision for column-width insertions.
+
+
+File: eplain.info, Node: Footnotes, Next: Fractions, Prev: Multiple columns, Up: User definitions
+
+4.17 Footnotes
+==============
+
+The most common reference mark for footnotes is a raised number,
+incremented on each footnote. The `\numberedfootnote' macro provides
+this. It takes one argument, the footnote text.
+
+ If your document uses only numbered footnotes, you could make typing
+`\numberedfootnote' more convenient with a command such as:
+
+ \let\footnote = \numberedfootnote
+
+After doing this, you can type your footnotes as `\footnote{FOOTNOTE
+TEXT}', instead of as `\numberedfootnote{FOOTNOTE TEXT}'.
+
+ Eplain keeps the current footnote number in the count register
+`\footnotenumber'. So, to reset the footnote number to zero, as you
+might want to do at, for example, the beginning of a chapter, you could
+say `\footnotenumber=0'.
+
+ Plain TeX separates the footnote marker from the footnote text by an
+en space (it uses the `\textindent' macro). In Eplain, you can change
+this space by setting the dimension register `\footnotemarkseparation'. The
+default is still an en.
+
+ You can produce a space between footenotes by setting the glue
+register `\interfootnoteskip'. The default is zero.
+
+ `\parskip' is also set to zero by default before the beginning of
+each footnote (but not for the text of the footnote).
+
+ You can also control footnote formatting in a more general way:
+Eplain expands the token register `\everyfootnote' before a footnote is
+typeset, but after the default values for all the parameters have been
+established. For example, if you want your footnotes to be printed in
+seven-point type, indented by one inch, you could say:
+
+ \everyfootnote = {\sevenrm \leftskip = 1in}
+
+ By default, an `\hrule' is typeset above each group of footnotes on
+a page. You can control the dimensions of this rule by setting the
+dimension registers `\footnoterulewidth' and `\footnoteruleheight'. The
+space between the rule and the first footnote on the page is determined
+by the dimension register `\belowfootnoterulespace'. If you don't want
+any rule at all, set `\footenoteruleheight=0pt', and, most likely,
+`\belowfootnoterulespace=0pt'. The defaults for these parameters
+typeset the rule in the same way as plain TeX: the rule is 0.4 points
+high, 2 true inches wide, with 2.6 points below it.
+
+ The space above the rule and below the text on the page is controlled
+by the glue register `\skip\footins'. The default is a plain TeX
+`\bigskip'.
+
+ Eplain can create hypertext links for the footnote marks (*note
+Footnote hyperlinks::).

+
+4.18 Fractions
+==============
+
+Exercise 11.6 of `The TeXbook' describes a macro `\frac' for setting
+fractions, but `\frac' never made it into plain TeX. So Eplain
+includes it.
+
+ `\frac' typesets the numerator and denominator in `\scriptfont0',
+slightly raised and lowered. The numerator and denominator are
+separated by a slash. The denominator must be enclosed in braces if
+it's more than one token long, but the numerator need not be. (This is
+a consequence of `\frac' taking delimited arguments; see page 203 of
+`The TeXbook' for an explanation of delimited macro arguments.)
+
+ For example, `\frac 23/{64}' turns `23/64' into 23/64 (you can't see
+the difference in the Info file).
+
+
+File: eplain.info, Node: Paths, Next: Logos, Prev: Fractions, Up: User definitions
+
+4.19 Paths
+==========
+
+When you typeset long pathnames, electronic mail addresses, or other
+such "computer" names, you would like TeX to break lines at punctuation
+characters within the name, rather than trying to find hyphenation
+points within the words. For example, it would be better to break the
+email address `letters@alpha.gnu.ai.mit.edu' at the `@' or a `.',
+rather than at the hyphenation points in `letters' and `alpha'.
+
+ If you use the `\path' macro to typeset the names, TeX will find
+these good breakpoints. The argument to `\path' is delimited by any
+character other other than `\' which does not appear in the name itself.
+`|' is often a good choice, as in:
+
+ \path|letters@alpha.gnu.ai.mit.edu|
+
+ You can control the exact set of characters at which breakpoints
+will be allowed by calling `\discretionaries'. This takes the same
+sort of delimited argument; any character in the argument will
+henceforth be a valid breakpoint within `\path'. The default set is
+essentially all the punctuation characters:
+
+ \discretionaries |~!@$%^&*()_+`-=#{}[]:";'<>,.?\/|
+
+ If for some reason you absolutely must use `\' as the delimiter
+character for `\path', you can set `\specialpathdelimiterstrue'.
+(Other delimiter characters can still be used.) TeX then processes the
+`\path' argument about four times more slowly.
+
+ The `\path' macro comes from `path.sty', written by Nelson Beebe and
+Philip Taylor and available at
+`http://www.ctan.org/tex-archive/macros/latex/contrib/misc/path.sty'.

+
+4.20 Logos
+==========
+
+Eplain redefines the `\TeX' macro of plain TeX to end with `\null', so
+that the proper spacing is produced when `\TeX' is used at the end of a
+sentence. The other ...TeX macros listed here do this, also.
+
+ Eplain defines `\AMSTeX', `\BibTeX' `\AMSLaTeX', `\LAMSTeX', `\LaTeX' `\MF', and
+`\SLiTeX' to produce their respective logos. (Sorry, the logos are not
+shown here.) Some spelling variants of these are also supported.
+
+ All these macros come from `texnames.sty', compiled by Nelson Beebe
+and available at
+`http://www.ctan.org/tex-archive/info/biblio/texnames.sty'.

+
+4.21 Boxes
+==========
+
+The solid rectangle that Eplain uses as a marker in unordered lists
+(*note Lists::) is available by itself: just say `\blackbox'.
+
+ You can create black boxes of arbitrary size with `\hrule' or
+`\vrule'.
+
+ You can also get unfilled rectangles with `\makeblankbox'. This
+takes two explicit arguments: the height and depth of the rules that
+define the top and bottom of the rectangle. (The two arguments are
+added to get the width of the left and right borders, so that the
+thickness of the border is the same on all four sides.) It also uses,
+as implicit arguments, the dimensions of `\box0' to define the
+dimensions of the rectangle it produces. (The contents of `\box0' are
+ignored.)
+
+ Here is an example. This small raised open box is suitable for
+putting next to numbers in, e.g., a table of contents.
+
+ \def\openbox{%
+ \ht0 = 1.75pt \dp0 = 1.75pt \wd0 = 3.5pt
+ \raise 2.75pt \makeblankbox{.2pt}{.2pt}
+ }
+
+ Finally, you can put a box around arbitrary text with `\boxit'. This
+takes one argument, which must itself be a (TeX) box, and puts a
+printed box around it, separated by `\boxitspace' white space (3 points
+by default) on all four sides. For example:
+
+ \boxit{\hbox{This text is boxed.}}
+
+ The reason that the argument must be a box is that when the text is
+more than one line long, TeX cannot figure out the line length for
+itself. Eplain does set `\parindent' to zero inside `\boxit', since it
+is very unlikely you would want indentation there. (If you do, you can
+always reset it yourself.)
+
+ `\boxit' uses `\ehrule' and `\evrule' so that you can easily adjust
+the thicknesses of the box rules. *Note Rules::.

+4.22 Checking for PDF output
+============================
+
+pdfTeX is a TeX variant that can output both `.dvi' and `.pdf' (Adobe's
+Portable Document Format) files (see
+`http://www.ctan.org/tex-archive/systems/pdftex'). You might sometimes
+want to know whether the target format is `.pdf' or `.dvi'. The
+`\ifpdf' switch can be used to detect pdfTeX in PDF mode:
+
+ \ifpdf
+ This text is produced when pdfTeX is in PDF mode.
+ \else
+ This text is produced when pdfTeX is in DVI mode,
+ or when some program other than pdfTeX is used.
+ \fi
+
+ Keep in mind that `\ifpdf' is set based on the value of the
+`\pdfoutput' primitive of pdfTeX at the time Eplain is loaded. If you
+change the value of `\pdfoutput' after you load Eplain, `\ifpdf' will
+not reflect the change.
+
+ Eplain defines `\ifpdf' by incorporating Heiko Oberdiek's
+`ifpdf.sty', which is available at
+`http://www.ctan.org/tex-archive/macros/latex/contrib/oberdiek/ifpdf.sty'.

+
+4.23 Loading LaTeX packages
+===========================
+
+Eplain provides a limited support for loading LaTeX packages (`.sty'
+files--not `.cls'). This will mostly work for packages which were
+designed with plain TeX compatibility in mind, which means that most
+LaTeX packages cannot be loaded. The packages which are known to work
+are listed below (*note Packages known to work::). If you discover a
+working package which is not in the list, please report it to the
+Eplain mailing list (*note Introduction::).
+
+ To set up a pseudo-LaTeX environment for the packages, Eplain uses
+`miniltx.tex'
+(`http://www.ctan.org/tex-archive/macros/plain/graphics/miniltx.tex')
+from the LaTeX graphics collection, written by David Carlisle and
+Sebastian Rahtz (the collection is available at
+`http://www.ctan.org/tex-archive/macros/latex/required/graphics').
+Eplain extends `miniltx.tex' to provide some additional features, e.g.,
+support for package options.

+File: eplain.info, Node: The \usepackage command, Next: Environment for loading packages, Up: Loading LaTeX packages
+
+4.23.1 The `\usepackage' command
+--------------------------------
+
+`\usepackage' loads a LaTeX package. Its syntax is similar to that of
+LaTeX's `\usepackage' command:
+
+ \usepackage[OPTIONS]{PACKAGES}[VERSION]
+
+where OPTIONS is a comma-separated list of package options, PACKAGES is
+a comma-separated list of packages to load (without the `.sty' suffix),
+and VERSION is a package version number given as a date in the format
+`YYYY/MM/DD'. If an older version of the package is found, a warning
+is issued. If several packages are loaded within a single `\usepackage'
+command, the OPTIONS will be applied to each of the packages. As
+usual, parameters in square brackets are optional and can be omitted
+(together with the square brackets).
+
+ For example:
+
+ \usepackage[foo,bar]{pack1,pack2}[2005/08/29]
+
+will load packages `pack1' and `pack2', each with the options `foo' and
+`bar', and will check that each of the packages are dated 2005/08/29 or
+newer.
+
+
+File: eplain.info, Node: Environment for loading packages, Next: Packages known to work, Prev: The \usepackage command, Up: Loading LaTeX packages
+
+4.23.2 Environment for loading packages
+---------------------------------------
+
+Some packages request that certain commands are executed after all
+packages have been loaded. In LaTeX, this means that the commands are
+executed at the beginning of the document, after the so-called
+"preamble". Neither plain TeX nor Eplain have any kind of preamble;
+therefore, Eplain requires that all packages be loaded inside a
+`\beginpackages...\endpackages' block, for example:
+
+ \beginpackages
+ \usepackage[foo,bar]{pack1}
+ \usepackage{pack2}
+ \endpackages
+
+This requirement enables Eplain to execute the "delayed" commands at
+the end of the `\beginpackages...\endpackages' block.
+
+ For the same reason, it is advisable to specify only one such block
+per document, just like there is only one preamble in LaTeX.
+
+ Some packages (and the pseudo-LaTeX environment, `miniltx.tex')
+redefine TeX's primitive `\input' to be a macro. Non-primitive
+`\input' is probably not what the user expects under plain TeX.
+Therefore, at the beginning of the `\beginpackages...\endpackages'
+block Eplain saves the meaning of `\input' as `\eplaininput' and
+restores the original `\input' at the end of the block. This usually
+means that the primitive `\input' is restored, unless you (or some
+other macro package you've loaded directly) have redefined it before
+calling `\beginpackages'. In case you need to access the
+package-provided `\input', Eplain saves it as `\packageinput'.
+
+ Sometimes you may encounter packages which make conflicting
+redefinitions of `\input'. Common symptoms are TeX spewing
+incomprehensible error messages or hanging in a loop at a call to
+`\input'. This sometimes can be cured by restoring `\input' to
+`\eplaininput' before loading each package. For example:
+
+ \beginpackages
+ \usepackage{pack1}
+ \let\input\eplaininput
+ \usepackage{pack2}
+ \endpackages

+4.23.3 Packages known to work
+-----------------------------
+
+The following table lists packages that had been tested and are known
+to work with Eplain, and locations where you can find manuals for these
+packages. Some of the short descriptions of the packages were taken
+from the documentation for those packages.
+
+autopict (`2001/06/04 v1.1j Picture mode autoload file')
+ `http://tug.org/eplain/misc/ltpictur.pdf'
+
+ This is the LaTeX "picture mode", started by `\begin{picture}' and
+ ended by `\end{picture}' (in LaTeX, this package is not explicitly
+ loaded since it is part of the LaTeX kernel). It provides
+ commands to draw simple figures inside your document without
+ resorting to any external tools.
+
+color (`1999/02/16 v1.0i Standard LaTeX Color (DPC)')
+graphics (`2001/07/07 v1.0n Standard LaTeX Graphics (DPC,SPQR)')
+graphicx (`1999/02/16 v1.0f Enhanced LaTeX Graphics (DPC,SPQR)')
+ `http://www.ctan.org/tex-archive/macros/latex/required/graphics/grfguide.pdf'
+
+ These packages are from the LaTeX graphics collection. They
+ provide commands for changing text/page colors, text rotation and
+ scaling, and much more.
+
+ *Warning 1:* If you encounter problems loading one of these
+ packages under pdfTeX (more specifically, when pdfTeX reads
+ `supp-mis.tex'), the cause may be an outdated `supp-mis.tex' (part
+ of ConTeXt, a typesetting system for TeX) installed on your
+ system. The problem was fixed in `supp-mis.tex'
+ version 2004.10.26. You can obtain up-to-date versions of
+ `supp-mis.tex' and the accompanying `supp-pdf.tex' from
+ `http://www.ctan.org/tex-archive/macros/pdftex/graphics'. To
+ convince TeX to use the new files, you have the following options
+ in the decreasing order of preference:
+
+ 1. put the new files in the same directory with your document;
+
+ 2. overwrite the outdated files installed by your TeX
+ distribution;
+
+ 3. install the new `supp-mis.tex' and `supp-pdf.tex' files in
+ the relevant subdirectory of your local `texmf' tree (for
+ info on TeX directory structure see
+ `http://www.tex.ac.uk/cgi-bin/texfaq2html?label=tds');
+
+ 4. upgrade your ConTeXt installation.
+
+ Note that option 1 is the safest but provides the fix only for
+ your current document. Options 2 and 3 will usually suffice for
+ Eplain but may break ConTeXt. Option 4 is the most general but is
+ more complicated than the first three. Be sure to backup any
+ files you overwrite. Also keep in mind that upgrading your TeX
+ distribution may overwrite files you install in the system `texmf'
+ tree.
+ *End of warning 1.*
+
+ *Warning 2:* If you encounter problems using the `\pagecolor'
+ command from the `color.sty' package under pdfTeX, the cause may
+ be an outdated pdfTeX color and graphics driver `pdftex.def'. The
+ problem was fixed in `pdftex.def' version 0.03p. You can obtain
+ an up-to-date version from
+ `http://www.ctan.org/tex-archive/graphics/pdftex/pdftex.def'.
+ *End of warning 2.*
+
+ The `graphics'/`graphicx' packages have the option `draft' which
+ instructs `\includegraphics' not to include the graphics but
+ instead typeset a box with the dimensions of the graphics and the
+ name of the graphics file in typewriter type at the center of the
+ box. These packages expect the LaTeX-provided command `\ttfamily'
+ to switch to the typewrite type. This command is not defined by
+ `miniltx.tex', therefore Eplain defines it and makes it equivalent
+ to plain TeX's `\tt'.
+
+ *Note Hyperlinks (xhyper.tex)::, for the demonstration of text
+ rotation and graphics inclusion using the `graphicx' package, and
+ using the `color' package to colorize hypertext links.

+
+5.1 Introduction to hyperlinks
+==============================
+
+The original TeX engine has no built-in support for hyperlinks (a.k.a.
+hypertext links). Many of the present-day file formats with
+hyperlinking capabilities did not even exist at the time TeX was
+written. However, TeX's `\special' primitive can be used to instruct
+TeX to write special directives into its `.dvi' output file. These
+directives are not interpreted by TeX in any way; they are intended for
+programs which process the `.dvi' files produced by TeX, be it printing
+or converting to other formats, such as `.ps' or `.pdf'.
+
+ Another approach is to extend the original TeX engine with the
+ability to generate one of the hyperlinking formats; TeX's set of
+primitives can be extended to include hyperlink commands. This is the
+approach used by the pdfTeX engine, which is capable of producing
+`.pdf' files directly from the TeX source, skipping the `.dvi'
+generation and processing step.
+
+ It turns out that the sets of commands for different formats are
+mostly not interchangeable, as each of the file formats has its own
+quirks and capabilities. And this is where Eplain "hyperlink drivers"
+come into play.
+
+ In order for Eplain to generate proper commands, Eplain has to know
+two things: which engine or `.dvi' processor you are using, and the set
+of commands it understands.
+
+ The knowledge about the commands that the various processors
+understand is programmed into Eplain's hyperlink drivers. Eplain
+provides three drivers: `hypertex' (implementation of the HyperTeX
+standard, see `http://arxiv.org/hypertex'), and `pdftex' and `dvipdfm'
+(named after the programs which process the hyperlink commands, pdfTeX
+and dvipdfm). Therefore, Eplain can only produce HyperTeX commands and
+hyperlink commands for one of these two programs--except that the
+extended `dvipdfmx' program can be used as well as the original
+`dvipdfm', since they are compatible.
+
+ To tell Eplain which `.dvi' processor or extended TeX engine you are
+using, use the command `\enablehyperlinks'.
+
+ For example:
+
+ \enablehyperlinks
+
+instructs Eplain to attempt to automatically detect which driver to
+use, as follows: if it detects pdfTeX in PDF mode, it loads the
+`pdftex' driver. If it does not detect pdfTeX in PDF mode, the
+`hypertex' driver is loaded. The detection is based on the `\ifpdf'
+switch (*note Checking for PDF output::).
+
+ If necessary, you can explicitly specify the driver name:
+
+ \enablehyperlinks[pdftex]
+
+will start producing hyperlinks under the assumption that you are using
+pdfTeX.
+
+ Eplain does not produce any hyperlinks until you explicitly enable
+them with `\enablehyperlinks'. For one thing, this keeps Eplain
+backward-compatible with previous releases without hyperlink support.
+For another, you may be using a program other than pdfTeX or `dvipdfm',
+which does not understand their hyperlink commands or the HyperTeX
+commands.
+
+Concepts and Terminology
+------------------------
+
+In general, hyperlinks work as follows. You mark some place in your
+document as a hyperlink destination, associating a "hyperlink label"
+with that destination. Next, somewhere within your document, you
+create a hyperlink, using a label to identify the destination you want
+this link to point to. A hyperlink is a region in the document (which
+can take many forms, for example, text or a picture); when a user
+clicks on that region, they will be taken to a place in the document
+marked by the corresponding destination. The following two sections
+(*Note Explicit hyperlinks::, and *Note Implicit hyperlinks::) describe
+the macros you can use to define destinations and create links pointing
+to those destinations.
+
+ In the rest of this chapter, we will often need to refer to links and
+destinations jointly, in which case we will use the term "hyperlinks".
+We will use the terms "links" and "destinations" in cases when we need
+to refer specifically to links or destinations.
+
+ Hyperlink drivers provide several kinds of links and destinations.
+We will refer to them as "link types" and "destination types".
+
+ For example, one of the destination types that the `pdftex' driver
+provides is the `xyz' type; when the user follows a link pointing to an
+`xyz' destination, the exact location marked by that destination is
+displayed. Another destination type provided by the `pdftex' driver is
+the `fit' type; when the user follows a link pointing to a `fit'
+destination, the page containing that destination is zoomed to fit into
+the window in which the document is displayed.
+
+ Similarly, drivers support various link types. For example, with the
+`pdftex' driver, the usual link type used to refer to destinations in
+the current document is called `name'. You can also create a link
+pointing to another local document (by using the `filename' link type)
+or to a URL (by using the `url' link type).
+
+ In addition, each hyperlink driver supports a number of destination
+and link "options". By setting these options you can customize
+hyperlink parameters (e.g., the thickness of the border drawn around a
+hyperlink) or pass information to hyperlinks (for example, file name of
+a document, for a link pointing to a destination in another document).
+
+ *Note Hyperlink drivers::, for the description of hyperlink types and
+options supported by the drivers. *Note Setting hyperlink types and
+options::, for the information on how to set hyperlink options.

+
+5.2 Explicit hyperlinks
+=======================
+
+Explicit hyperlinks are created by you, in the source of your document.
+The simplest command is `\hldest', which marks the current position in
+your document as a destination:
+
+ \hldest{TYPE}{OPTIONS}{LABEL}
+
+Here TYPE is one of the destination types supported by the hyperlink
+driver (*note Hyperlink drivers::), OPTIONS is a comma-separated list
+of option assignments, and LABEL is the hyperlink label to associate
+with this destination. This label will identify the destination when
+creating links pointing to this destination. For example, with the
+`pdftex' driver, the command
+
+ \hldest{xyz}{zoom=2000}{index}
+
+creates a destination of type `xyz' ("the current position"), sets the
+magnification ratio for this destination to be 200%, and associates the
+label `index' with the destination.
+
+ Another command, `\hlstart', paired with `\hlend', turns all
+intervening material into a link:
+
+ \hlstart{TYPE}{OPTIONS}{LABEL} ... \hlend
+
+Here TYPE, OPTIONS and LABEL have the same meaning as for `\hldest'.
+Continuing the previous example,
+
+ \hlstart{name}{bstyle=U,bwidth=2}{index} Index\hlend
+
+typesets the word `Index' as a link with underline border of
+width 2 PostScript points, pointing to the named destination `index'
+defined in the previous example. (The other options, like highlight
+mode and border color, are determined by the defaults, *note Setting
+default types and options::).
+
+ The LABEL argument of both `\hldest' and `\hlstart' can contain
+special characters (such as `#', `%', `&', `~', etc.) without any
+escaping. This is especially important for URL links supported by some
+drivers (*note Hyperlink drivers::).
+
+ Both `\hldest' and `\hlstart' ignore following spaces.
+
+ Both `\hldest' and `\hlstart' expand the first token of OPTIONS
+once, so you can save a list of options in a macro and pass it for the
+OPTIONS. For example:
+
+ \def\linkopts{bstyle=U,bwidth=2}
+ \hlstart{name}{\linkopts}{index}Index\hlend
+
+is functionally equivalent to the previous example.
+
+ *Note Hyperlinks (xhyper.tex)::, for a demonstration of the usage of
+explicit hyperlinks.

+
+5.3 Implicit hyperlinks
+=======================
+
+"Implicit hyperlinks" are hyperlinks created implicitly by various
+Eplain macros, such as the macros for citations, cross-references,
+indexing, etc.
+
+ All such macros are divided into "link groups" and "destination
+groups" (or "linkgroups" and "destgroups" for short) so that parameters
+can be set individually for each group. For example, all equation
+macros which define a destination are assigned to the `eq' destgroup;
+equation macros which create a link are assigned to the `eq' linkgroup.
+By setting parameters for the `eq' linkgroup (destgroup), you can
+uniformly customize all links (destinations) related to equation
+references, without interfering with settings for the other groups.
+
+ *Note Setting hyperlink types and options::, for information on how
+to set parameters for a group.
+
+ Here is the list of the linkgroups:
+
+ hrefint, hrefext, url, cite, ref, xref, eq, idx, foot, footback.
+
+ And here are the destgroups:
+
+ bib, li, definexref, xrdef, eq, idx, foot, footback.
+
+ *Note Hyperlinks (xhyper.tex)::, for a demonstration of the usage of
+implicit hyperlinks.
+
+ The following subsections describe each of the linkgroups and
+destgroups and the hyperlink support provided.
+
+* Menu:

+* General hyperlinks:: hrefint, hrefext
+* URL hyperlinks:: url

+* Page reference hyperlinks:: xrdef, xref
+* Equation reference hyperlinks:: eq
+* Index hyperlinks:: idx
+* Footnote hyperlinks:: foot, footback
+* Contents hyperlinks::
+
+
+File: eplain.info, Node: General hyperlinks, Next: URL hyperlinks, Up: Implicit hyperlinks
+
+5.3.1 General hyperlinks: hrefint, hrefext
+-------------------------------------------
+
+`\href{URL}{TEXT}' typesets TEXT as a link to URL. It basically does
+what the explicit hyperlink macros do (*note Explicit hyperlinks::),
+but is more convenient (at the expense of flexibility).
+
+ If URL starts with `#', the rest of URL is assumed to be a local
+hyperlink destination name (destination within the same document).
+Parameters for these links can be set by customizing the `hrefint'
+linkgroup. For example:
+
+ See \href{#intro}{Introduction}
+
+will make `Introduction' into an internal link, which might have been
+created, e.g., with `\xrdef{intro}'.
+
+ If URL does not start with `#', it is assumed to be a URL link.
+Parameters for these links can be set by customizing the `hrefext'
+linkgroup. The special characters (such as `#' and `~') in the URL
+don't need to be escaped. For example:
+
+ \href{http://tug.org/eplain/doc/eplain.html#Hyperlinks}{Hyperlinks
+ in Eplain}
+
+*Note URL hyperlinks::, for another way to create URL hyperlinks.
+
+ The TEXT argument of `\href' can contain verbatim text (*note
+Verbatim listing::) or other macros which manipulate character
+catcodes. For example:
+
+ \href{#WeirdChars}{The weird chars \verbatim #&%$~|endverbatim}
+
+ `\href' does not currently handle other link types, such as `file:'
+and `run:' links.
+
+
+File: eplain.info, Node: URL hyperlinks, Next: Citation hyperlinks, Prev: General hyperlinks, Up: Implicit hyperlinks
+
+5.3.2 URL hyperlinks: url
+--------------------------
+
+The `url' linkgroup covers the `\url' command from the LaTeX package `url'
+(*note Packages known to work::), as well as any new `\url'-like
+commands you define. The type for this linkgroup is set to `url' by
+the drivers which support this link type. `url' links use the
+parameter to the `\url' command as the URL to point to.
+
+ You may be using the `\url' command to typeset something other than
+a URL, e.g., a path, for which you do not want a link to be created; in
+that case, you can disable the `url' linkgroup with the command
+`\hloff[url]' (*note Turning hyperlinks on/off for a group::).
+
+ By default, URL (and other types of) links are boxed, so that they
+are visually marked even if you do not load the LaTeX `color' package
+(*note Loading LaTeX packages::) and therefore link text is not
+colored. You can see the effect by compiling the following code
+snippet (be sure to get a modern `url.sty', older versions do not work
+in plain TeX; *note Packages known to work::):
+
+ \input eplain
+ \beginpackages
+ \usepackage{url}
+ \endpackages
+
+ \enablehyperlinks
+
+ \url{http://foo/bar}
+ \bye
+
+ If the hyperlink driver you use supports the link option `bwidth'
+(*note Hyperlink drivers::), you can produce colored links with no
+border around them. Try this:
+
+ \input eplain
+ \beginpackages
+ \usepackage{url}
+ \usepackage{color}
+ \endpackages
+
+ \enablehyperlinks
+ \hlopts{bwidth=0}
+
+ \url{http://foo/bar}
+ \bye
+
+The command `\hlopts{bwidth=0}' sets border width to zero as the
+default for all links, and loading the `color' package automatically
+colors links using the default color (*note Options supported by all
+drivers::). If you want the border width setting to apply to URL links
+only, say `\hlopts[url]{bwidth=0}' (*note Setting hyperlink types and
+options::).

+
+5.3.3 Citation hyperlinks: cite, bib
+-------------------------------------
+
+The `cite' linkgroup includes only the `\cite' command (*note
+Citations::). `\cite' turns each of the references in the list into a
+link pointing to the respective bibliography entry produced by the
+`\bibliography' command.
+
+ The `bib' destgroup includes the macros related to the
+`\bibliography' command (*note Citations::). `\bibliography' inputs a
+`.bbl' file, which contains a list of bibliography entries. For each
+of the entries, a destination is defined.
+
+ Both commands use the citation label as the hyperlink label.
+
+
+File: eplain.info, Node: List hyperlinks, Next: Cross-reference hyperlinks, Prev: Citation hyperlinks, Up: Implicit hyperlinks
+
+5.3.4 List hyperlinks: li
+--------------------------
+
+The `li' destgroup consists of the `\li' command (*note Lists::), which
+defines a destination if you supply the optional argument
+(cross-reference label). This label is also used as the hyperlink
+label.
+
+
+File: eplain.info, Node: Cross-reference hyperlinks, Next: Page reference hyperlinks, Prev: List hyperlinks, Up: Implicit hyperlinks
+
+5.3.5 Cross-reference hyperlinks: definexref, ref
+--------------------------------------------------
+
+The `definexref' destgroup is for the `\definexref' command (*note
+Defining generic references::). `\definexref' defines a destination
+using the cross-reference label (the first argument) as the hyperlink
+label.
+
+ The `ref' linkgroup includes `\refn' and `\xrefn' (they are
+synonyms), `\ref', and `\refs' (*note Using generic references::).
+
+ `\refn' turns the cross-reference it produces into a link, using the
+cross-reference label as the hyperlink label. If an optional argument
+is present, it is tied by `\reftie' to the reference and become part of
+the link.
+
+ `\ref' works similarly to `\refn'. It takes an optional argument,
+which is treated the same way as the optional argument to `\refn'. In
+addition, `\ref' can produce a "class word". Both the optional
+argument and the class word become part of the link, when present. The
+cross-reference is tied by `\reftie' to the preceding word. The
+optional argument is separated from the class word by `\refspace'.
+
+ Unlike `\ref', `\refs' does not take an optional argument and does
+not make the class word part of the link, which is appropriate for its
+intended use.

+
+5.3.6 Page reference hyperlinks: xrdef, xref
+---------------------------------------------
+
+The `xrdef' destgroup is for `\xrdef' (*note Page references::).
+`\xrdef' defines a destination using cross-reference label as the
+hyperlink label.
+
+ The `xref' linkgroup includes the `\xref' command (*note Page
+references::). `\xref' turns its optional argument (followed by
+`\refspace'), `\xrefpageword' and the cross-reference (page number)
+into a link, using the cross-reference label as the hyperlink label.
+
+
+File: eplain.info, Node: Equation reference hyperlinks, Next: Index hyperlinks, Prev: Page reference hyperlinks, Up: Implicit hyperlinks
+
+5.3.7 Equation reference hyperlinks: eq
+----------------------------------------
+
+All commands that define equation labels are part of the `eq' destgroup.
+These are `\eqdef', `\eqdefn', `\eqsubdef' and `\eqsubdefn' (*note
+Equation references::). All these commands use the equation label as
+the hyperlink label. However, if the equation label is empty, they
+make up a (hopefully) unique hyperlink label for the destination. This
+label will be used for the link when you refer to this empty-labeled
+equation with one of the equation reference macros.
+
+ The command `\phantomeqlabel' is called to generate hyperlink labels
+for the empty-labeled equations. By default, it produces the labels in
+the format `PHEQNUMBER', where NUMBER comes from the count register
+`\phantomeqnumber'; this count register is incremented at every
+empty-labeled equation definition.
+
+ The commands `\eqref' and `\eqrefn' (*note Equation references::)
+form the `eq' linkgroup. These commands take an optional argument,
+which, when present, is tied with `\reftie' to the equation reference
+and becomes part of the link. The equation label is used for the
+hyperlink label; if the label is empty, the link is for the label
+generated for the last empty-labeled equation.
+
+
+File: eplain.info, Node: Index hyperlinks, Next: Footnote hyperlinks, Prev: Equation reference hyperlinks, Up: Implicit hyperlinks
+
+5.3.8 Index hyperlinks: idx
+----------------------------
+
+All indexing commands (`\idx', `\idxname', `\idxmarked',
+`\idxsubmarked' and their silent equivalents, *note Indexing
+commands::) form the `idx' destgroup. The `idx' linkgroup consists of
+the macros which are used to typeset the index when you say `\readindexfile{INDEX-LETTER}'
+(*note Typesetting an index::).
+
+ To create the links in index entries, Eplain uses MakeIndex's
+"encapsulation" feature. When you use an indexing macro to mark an
+index term, Eplain writes out a line to the `.idx' file of the
+following general form:
+
+ \indexentry{ENTRY|PAGEMARKUP}{PAGENO}
+
+where ENTRY is the index entry (converted into the internal format that
+MakeIndex understands), CS is the markup command you specified with the
+`pagemarkup=CS' optional argument to the indexing commands (*note
+Modifying index entries::), and PAGENO is the page number on which the
+term appeared. When processing the `.idx' file, MakeIndex makes the
+page number an argument to the page markup command ("encapsulates" the
+page number), so the page number in the `.ind' file appears as
+`\CS{PAGENO}'. Eplain internally replaces the CS command name with its
+own command, which, in addition to calling the original `\CS'
+encapsulator, turns the page number into a link.
+
+ Eplain provides two approaches to linking page numbers in the index
+to locations of index terms in the text.
+
+* Menu:
+
+* Exact destinations for index terms::
+* Page destinations for index terms::
+* Choosing destination placement::
+* Index page list and page range parsers::
+* Hyperlinks in see and see also entries::
+
+
+File: eplain.info, Node: Exact destinations for index terms, Next: Page destinations for index terms, Up: Index hyperlinks
+
+5.3.8.1 Exact destinations for index terms
+..........................................
+
+In this approach, each command that marks an index term defines a unique
+destination and passes its label on to the `.idx' file as part of the
+`\indexentry' command. The `\indexentry' line that Eplain writes to
+the `.idx' file becomes
+
+ \indexentry{ENTRY|hlidx{LABEL}{CS}}{PAGENO}
+
+where `\hlidx' is the command that is defined by Eplain to take three
+arguments: a hyperlink label (LABEL), a name of page number
+encapsulator (CS) and a page number (PAGENO). In the `.ind' file that
+MakeIndex will generate, the page number will now appear as
+
+ \hlidx{LABEL}{CS}{PAGENO}
+
+The result of this command is `\CS{PAGENO}', wrapped up into a link
+pointing to LABEL destination.
+
+ The hyperlink labels for the index terms are generated by the `\hlidxlabel'
+command, by default in the format `IDXNUMBER', where NUMBER is the
+value of the count register `\hlidxlabelnumber'. This count register
+is incremented at each index term.
+
+ The advantage of this approach, as compared to the second approach
+described below, is that links in the index point to exact locations of
+the indexed terms on the page. The disadvantage of this approach is
+that MakeIndex will regard _all_ index entries as distinct, because
+each one contains a (unique) hyperlink label. This disadvantage can be
+partially overcome by the script `idxuniq' distributed with Eplain in
+the `util' directory. This script filters out `\indexentry' lines
+differing only in the hyperlink label but identical otherwise. You
+should process the `.idx' with this script before passing it on to
+MakeIndex. For example:
+
+ prompt$ ./idxuniq file.idx | makeindex > file.ind
+
+Still, this solution is not ideal, as the page-range formation ability
+of MakeIndex will not work, and there will be problems of apparently
+identical index entries clashing (e.g., when a range-end entry appears
+on the same page as another entry with the same definition; `idxuniq'
+will not filter out the second entry).
+
+
+File: eplain.info, Node: Page destinations for index terms, Next: Choosing destination placement, Prev: Exact destinations for index terms, Up: Index hyperlinks
+
+5.3.8.2 Page destinations for index terms
+.........................................
+
+In the second approach, Eplain does not write out any destination labels
+for the index terms. Instead, Eplain writes out a wrapper for page
+number encapsulator which can parse the page number and generate a link
+pointing to the _page_ on which the term appeared. On top of each page
+containing an index term, Eplain defines a destination with label
+produced by `\hlidxpagelabel'. The `\hlidxpagelabel' command takes a
+single argument (page number NUMBER) and by default produces the label
+in the format `IDXPGNUMBER'.
+
+ With this approach, the `\indexentry' line which Eplain writes to
+the `.idx' file looks like this:
+
+ \indexentry{ENTRY|hlidxpage{CS}}{PAGENO}
+
+where `\hlidxpage' is the command that is defined by Eplain to take two
+arguments: a name of page number encapsulator (CS) and a page number
+(PAGENO). In the `.ind' file that MakeIndex will generate, the page
+number will appear as
+
+ \hlidxpage{CS}{PAGENO}
+
+ The advantage of this approach is that all features of MakeIndex are
+intact. The drawback is that links in the index do not point to exact
+locations of indexed terms on a page, but to the top of a page on which
+the term appears.
+
+ Another disadvantage is that this approach depends on the page range
+and page list separators which MakeIndex was configured to output.
+`\hlidxpage' must be able to parse the first page number in a page
+range like `1--4'. In addition, page list parsing is needed because
+MakeIndex combines two consecutive page numbers in one call to the page
+number encapsulator, so `\hlidxpage' can be passed, e.g., `1, 2' for
+the PAGENO. In this last case, `\hlidxpage' splits the two page
+numbers, applies `\CS' to each of them, and makes each of the page
+numbers a link to the appropriate page. Note that this will alter
+typesetting slightly, because now the page list separator (a comma
+followed by a space, by default) is not typeset using the page number
+encapsulator (`\CS').
+
+ Eplain's defaults for the page list and page number delimiters are
+the same as those in MakeIndex, a comma followed by a space (`, ') and
+two dashes (`--'), respectively. If you customize MakeIndex to use
+different delimiters, you must not forget to let Eplain know about them
+with the commands
+
+ \setidxpagelistdelimiter{LIST-DELIM}
+ \setidxpagerangedelimiter{PAGE-DELIM}
+
+(*note Page list and page range parsers::).

+
+5.3.8.3 Choosing destination placement
+......................................
+
+The approach that Eplain should use for the index terms can be selected
+in the `\enablehyperlinks' command. The optional argument it accepts is
+a comma-separated list of options. The `idxexact' option selects the
+first approach, `idxpage' the second, and `idxnone' disables hyperlink
+support for the index terms altogether, in case you want to stop Eplain
+from writing its link wrappers into the `.idx' file. The default is
+`idxpage'.
+
+ For example:
+
+ \enablehyperlinks[idxexact]
+
+selects the first approach ("exact index links").

+
+5.3.8.4 Index page list and page range parsers
+..............................................
+
+The macros that Eplain uses to parse page lists and page ranges,
+`\idxparselist' and `\idxparserange', can sometimes be useful when
+defining page number encapsulators. *Note Page list and page range
+parsers::, for the description of these commands and an example of their

+
+5.3.8.5 Hyperlinks in see and see also entries
+..............................................
+
+There is no automatic support for hyperlinks with "see" and "see also"
+index entries, as there is not enough information to trace the
+parameters of `\indexsee' and `\indexseealso' to corresponding index
+entries. But if desired, this can be implemented with `\hldest' and
+`\hlstart' (*note Explicit hyperlinks::); for example:
+
+ \sidx{semantic theory of truth@%
+ \leavevmode\hldest{}{}{idx:theo truth}semantic theory of truth}
+ ...
+ \sidx[seealso]{truth}[definition of]%
+ {\hlstart{}{}{idx:theo truth}semantic theory of truth\hlend}

+
+5.3.9 Footnote hyperlinks: foot, footback
+------------------------------------------
+
+The `foot' link and destination groups include the `\numberedfootnote'
+and `\footnote' macros (*note Footnotes::). The `footback' groups
+include the same macros, but control parameters for links and
+destinations created inside the footnote to point back to the footnote
+mark within the text body.
+
+ The macros use hyperlink labels generated by `\hlfootlabel' and `\hlfootbacklabel'.
+The default formats for the labels are `FOOTNUMBER' and `FOOTBNUMBER',
+respectively, where NUMBER is the value of the count register `\hlfootlabelnumber'.
+This register is incremented at every footnote.
+
+ Generally, footnote hyperlinks are not of much use, because the
+footnotes are usually placed on the same page as the footnote mark.
+Therefore, footnote hyperlinks are disabled by default. Here is how you
+can turn them on selectively, without affecting the other kinds of
+hyperlinks (*note Turning hyperlinks on/off for a group::):

+--------------------------
+
+There is currently no special support for hyperlinks in the table of
+contents (*note Contents::), but implementing them with the `\hldest'
+and `\hlstart ... \hlend' commands (*note Explicit hyperlinks::) should
+be possible.

+they support, and the options they accept. During the first reading,
+you may only want to skim through this section.

+
+5.4.1 Options supported by all drivers
+--------------------------------------
+
+This subsection describes the destination and link options which are
+supported by all hyperlink drivers.
+
+Destination options supported by all drivers
+............................................
+
+`raise'
+ Specifies how much to raise destinations above the baseline. When
+ set to zero or empty, destinations are placed at the baseline.
+
+ It is usually convenient to set this option to some variable
+ parameter, so that the height to which destinations are raised is
+ automatically adjusted according to the current context. For
+ example, setting it to `\normalbaselineskip' (or some fraction of
+ it, like `1.7\normalbaselineskip') makes the setting appropriate
+ for different point sizes, in case your document uses more than
+ one.
+
+ The default setting is `\normalbaselineskip'. Initially, the
+ destgroups do not define this option, so they fall back on the
+ default, except for the `eq' destgroup, for which this option is
+ set to `1.7\normalbaselineskip', to accommodate the usual cases of
+ large operators in displayed math.
+
+ Example: `\hldestopts[eq]{raise=2.5\normalbaselineskip}'
+
+Link options supported by all drivers
+.....................................
+
+`colormodel'
+`color'
+ These two options define the color to be used for rendering the
+ link text. The colors are used only when a `\color' command is
+ defined, e.g., by loading the LaTeX `color' package (*note
+ Packages known to work::). The `\color' command is called as
+ `\color[COLORMODEL]{COLOR}', where COLORMODEL and COLOR are the
+ definitions of the `colormodel' and `color' options, respectively.
+ However, if COLORMODEL is empty, the optional argument to
+ `\color' is omitted; and if COLOR is empty, the `\color' command
+ is omitted altogether. The default setting is `COLORMODEL=cmyk'
+ and `COLOR=0.28,1,1,0.35'.
+
+ When specifying colors with several components delimited by commas
+ (e.g., RGB and CMYK colors in the LaTeX `color' package), it is not
+ possible to specify the components directly in the option list of
+ `\hlopts', because comma is the option list delimiter. With the
+ `color' package, it is possible to specify such colors by defining
+ a custom color with `\definecolor' and using the new color name
+ with an empty COLORMODEL (see examples below).
+
+ Examples:
+
+ \hlopts{colormodel=,color=blue}% predefined color
+ \definecolor{mycolor}{rgb}{.3,.8,.95}
+ \hlopts{colormodel=,color=mycolor}% custom color
+ \hlopts{colormodel=gray,color=.4}

+
+5.4.2 Hyperlink driver `hypertex'
+---------------------------------
+
+HyperTeX is a standard for inclusion of hyperlink information in TeX
+(and LaTeX) documents (see `http://arxiv.org/hypertex'). This standard
+defines a set of hyperlink tags implemented as `\special' commands
+written into the DVI file. The major advantage of such standard is
+that a single `.dvi' file containing HyperTeX commands can be viewed by
+any HyperTeX-enabled viewer (e.g., any more or less modern version of `xdvi')
+or converted to other file formats (e.g., PDF) by any HyperTeX-enabled
+DVI converter (e.g., `dvipdfmx' or `dvips' with Ghostscript's `ps2pdf'
+script).
+
+ The downside to the standard is that it is by design "the common
+factor" of other formats supporting hyperlinks, so many features of a
+particular file format cannot be supported by HyperTeX. Therefore, if
+you need to use special features of a particular format, HyperTeX is
+not a good choice. For the PDF file format, Eplain provides the
+`pdftex' and `dvipdfm' drivers which provide fine control over the PDF
+options (*note Hyperlink drivers pdftex and dvipdfm::).
+
+ For more information on programs which support the HyperTeX standard,
+please see
+
+ `http://arxiv.org/hypertex'
+ `http://www.tug.org/tex-archive/support/hypertex/hypertex'
+
+For convenience, we list a few HyperTeX-enabled converters:
+
+`dvips'
+ Note that you need to pass the `-z' option to `dvips' to tell it
+ to preserve the information about the hyperlinks. To generate a
+ `.pdf' file with hyperlinks, you can use the `ps2pdf' script of Ghostscript.
+ For example, if `foo.tex' is a TeX file using HyperTeX commands,
+ then
+
+ prompt$ tex foo.tex
+ prompt$ dvips -z foo.dvi -o
+ prompt$ ps2pdf foo.ps
+
+ will produce `foo.pdf' with hyperlinks.
+
+`dvipdfm'
+`dvipdfmx'
+ No special command line arguments are required, these programs
+ automatically detect the HyperTeX commands.
+
+
+ One more note is in place: support for the HyperTeX commands varies
+from one previewer/converter to another, so you might need to experiment
+to see if what you need is supported by the program(s) you intend to
+use. For example, dvips(k) as of version 5.92b converts all internal
+hyperlinks into page links pointing to a page containing the
+destination, so that "exact" linking to destinations is not possible
+(this was confirmed to be a bug and most probably has already been fixed
+in later versions of dvips(k)); dvipdfm as of version 0.13.2c and
+dvipdfmx as of version 20040411 do not correctly parse links to
+external local files, and produce a URL link instead of a file link.

+
+`xyz'
+ "Current position". This is the default type.
+
+ Example: `\hldest{xyz}{}{dest123}'
+
+`raw'
+ The destination specification (in the form of a HyperTeX
+ `\special') is taken from the command sequence `\CS', where CS is
+ the value of the `cmd' option. In the definition of `\CS', use `\@hllabel'
+ to refer to the hyperlink label. This option is intended to be
+ used with destgroups (*note Setting hyperlink types and
+ options::), as it does not make sense in a direct call to `\hldest'--you

+.................................
+
+`name'
+ Go to a "named destination". The label is the destination name.
+ All destinations in HyperTeX are named destinations. This is the
+ default type.
+
+ Example: `\hlstart{name}{}{dest123}Link to dest123\hlend'
+
+`url'
+ Go to a URL. The label is the URL.
+
+ Example:
+
+ `\hlstart{url}{}{http://tug.org/eplain/}Eplain home\hlend'
+
+`filename'
+ Go to a named destination in another file. The label is the
+ destination name. The file name is specified by the `file'
+ option. The file name extension can be specified separately by the `ext'
+ option. The idea is to set the `ext' option globally at the
+ beginning of the document to avoid hard-coding the extension
+ together with the file name within each link--HyperTeX is not
+ restricted to any single output format, it can be DVI, PDF,
+ possibly other formats.
+
+ Example:
+
+ \hlopts{ext=.pdf}
+ \hlstart{filename}{file=book}{dest123}
+ Link to dest123 in file `book.pdf'\hlend
+
+`raw'
+ The link specification (in the form of a HyperTeX `\special') is
+ taken from the command sequence `\CS', where CS is the value of the `cmd'
+ option. In the definition of `\CS', use `\@hllabel' to refer to
+ the hyperlink label. Use the predefined command `\hlhash' to
+ insert the `#' characters. This option is intended to be used
+ with linkgroups (*note Setting hyperlink types and options::), as
+ it does not make sense in a direct call to `\hlstart'--you can
+ just call the raw command.
+
+ Example:
+
+ \makeatletter

+....................................................
+
+`xyz'
+ "Current position". The option `zoom' specifies magnification to
+ use (zero or empty means leave magnification unchanged, which is
+ the default). This is the default type.
+
+ For `dvipdfm': the options `left' and `top' specify position
+ coordinates to use (empty options mean current position
+ coordinate, which is the default).
+
+ Example: `\hldest{xyz}{zoom=2000}{dest123}'
+
+`fit'
+ Fit the page to the window.
+
+ Example: `\hldest{fit}{}{dest123}'
+
+`fith'
+ Fit the width of the page to the window.
+
+ For `dvipdfm': the `top' option specifies vertical position
+ (default is empty, meaning current position).
+
+ Example: `\hldest{fith}{}{dest123}'
+
+`fitv'
+ Fit the height of the page to the window.
+
+ For `dvipdfm': The option `left' specifies horizontal position
+ (default is empty, meaning current position).
+
+ Example: `\hldest{fitv}{}{dest123}'
+
+`fitb'
+ Fit the page's bounding box to the window.
+
+ Example: `\hldest{fitb}{}{dest123}'
+
+`fitbh'
+ Fit the width of the page's bounding box to the window.
+
+ For `dvipdfm': the option `top' specifies vertical position
+ (default is empty, meaning current position).
+
+ Example: `\hldest{fitbh}{}{dest123}'
+
+`fitbv'
+ Fit the height of the page's bounding box to the window.
+
+ For `dvipdfm': the option `left' specifies horizontal position
+ (default is empty, meaning current position).
+
+ Example: `\hldest{fitbv}{}{dest123}'
+
+`fitr'
+ For `pdftex': fit the rectangle specified by the options `width', `height'
+ and `depth' (as a TeX rule specification) in the window. For
+ dimensions set to empty, the corresponding value of the parent box
+ is used (these are the defaults).
+
+ For `dvipdfm': fit the rectangle specified by the options `left', `bottom', `right'
+ and `top' (in PostScript points, 72 points per inch) in the
+ window. For dimensions set to empty, current position coordinate
+ is substituted (these are the defaults).
+
+ Example for `pdftex':
+
+ \hldest{fitr}{width=\hsize,
+ height=.5\vsize,depth=0pt}{dest123}

+
+ *Note Destination types for pdftex and dvipdfm::, the description
+ of the `raw' destination, for an example.
+
+`zoom'
+ Magnification ratio times 1000 (like TeX's scale factor). Zero or

+
+ Example: `\hldest{xyz}{zoom=2000}{dest123}'
+
+`pdftex'-specific destination options
+.....................................
+
+The dimension options below must be specified as a TeX rule
+specification. When set to empty, the corresponding value of the
+parent box is used (this is the default for all dimension options).
+
+`depth'
+ Depth of the fit rectangle for the `fitr' destination.
+
+`height'
+ Height of the fit rectangle for the `fitr' destination.
+
+`width'
+ Width of the fit rectangle for the `fitr' destination.

+ \hldest{fitr}{width=\hsize,
+ height=.5\vsize,depth=0pt}{dest123}
+
+`dvipdfm'-specific destination options
+......................................
+
+The dimension options below must be specified in PostScript points
+(72 points per inch), as a number without the `bp' unit name. When set

+
+5.4.3.3 Link types for `pdftex' and `dvipdfm'
+.............................................
+
+Link types are the same for the `pdftex' and `dvipdfm' drivers, except
+that the `pdftex' driver provides one additional link type `num' (link
+to a numbered destination). dvipdfm does not support numbered
+destinations, therefore it does not have this link type. Note that all
+destinations created by Eplain hyperlink macros are named destinations;
+to define a numbered destination, you have to use low-level pdfTeX
+commands.
+
+Common link types
+.................
+
+`name'
+ Go to a "named destination". The label is the destination name.
+ All destinations created with `\hldest' are named destinations
+ (*note Explicit hyperlinks::). This is the default type.
+
+ Example: `\hlstart{name}{}{dest123}Link to dest123\hlend'
+
+`url'
+ Go to a URL. The label is the URL.
+
+ Example: `\hlstart{url}{}{http://tug.org/eplain/}Eplain
+ home\hlend'
+
+`page'
+ Go to a page. The label is the page number (counting from 1).
+ Page fitting is specified by the `pagefit' option.
+
+ Example:
+
+ \hlstart{page}{pagefit=/FitH 600}{123}
+ Link to page~123\hlend
+
+`filename'
+ Go to a named destination in another file. The label is the
+ destination name. The file name is specified by the `file'
+ option. Page fitting is specified by the `pagefit' option. The `newwin'
+ option specifies whether the destination document is opened in the
+ same window or in a new window.
+
+ Example:
+
+ \hlstart{filename}{file=book.pdf,newwin=1}{dest123}
+ Link to dest123 in file `book.pdf'\hlend
+
+`filepage'
+ Go to a page in another file. The label is the page number
+ (counting from 1). The file name is specified by the `file'
+ option. Page fitting is specified by the `pagefit' option. The `newwin'
+ option specifies whether the destination document is opened in the
+ same window or in a new window.
+
+ Example:
+
+ \hlstart{filepage}{file=book.pdf,newwin=,
+ pagefit=/FitR 50 100 300 500}{1}
+ Link to page~1 in file `book.pdf'\hlend
+
+`raw'
+ The link specification (in the form of a pdfTeX command or a
+ dvipdfm `\special' primitive) is taken from the command sequence
+ `\CS', where CS is the value of the `cmd' option. In the
+ definition of `\CS', use `\@hllabel' to refer to the hyperlink
+ label. This option is intended to be used with linkgroups (*note
+ Setting hyperlink types and options::), as it does not make sense
+ in a direct call to `\hlstart'--you can just call the raw command.
+
+ Example for `pdftex':
+
+ % Redirect all \url links to the first page
+ \def\mycmd{\pdfstartlink goto page 1 {/Fit}}
+ \hltype[url]{raw}
+ \hlopts[url]{cmd=mycmd}
+
+ Example for `dvipdfm':
+
+ % Redirect all \url links to the first page
+ \def\mycmd{\special{pdf: beginann <</Type/Annot /Subtype/Link
+ /Dest[0 /Fit]>>}}
+ \hltype[url]{raw}
+ \hlopts[url]{cmd=mycmd}

+5.4.4 Hyperlink driver `nolinks'
+--------------------------------
+
+Select this driver to suppress all hyperlinks in your document.
+
+ Selecting this driver is quite different from not selecting any
+driver at all, or from selecting some driver and then turning
+hyperlinks off for the entire document with `\hloff' and `\hldestoff'
+(*note Turning hyperlinks on/off::).
+
+ The purpose of `\hldestoff' and `\hloff' is to mark (parts) of your
+document where hyperlinks should never appear. (Imagine you want to
+prevent a cross-referencing macro from generating a link at a certain
+spot in your document.)
+
+ If instead you have prepared a document with hyperlinks and just
+want to compile a version without them, it is better to select the
+driver `nolinks'. This ensures that spacing and page-breaking are the
+same as what you were getting with hyperlinks enabled.
+
+ The reason for this is that hyperlinks are produced by the
+`\special' primitives or low-level hyperlink commands. Each such
+command is placed inside a "whatsit" (an internal TeX object), which
+may introduce legitimate breakpoints at places where none would exist
+without the whatsits. The macros `\hldestoff' and `\hloff' disable the
+hyperlink macros completely, so that no whatsits are produced.
+
+ In contrast, the `nolinks' driver does not completely disable
+hyperlink macros. Instead, it defines them to merely write to the log
+file (what gets written is unimportant). This also produces whatsits,
+thus imitating the whatsits from the hyperlink commands. (This trick
+was borrowed from the LaTeX `color' package.)
+
+ Another reason for using `nolinks' is that in horizontal mode
+`\hldest' places destinations inside boxes of zero width, height, and
+depth. When you say `\hldestoff', `\hldest' will omit both destination
+definitions and these boxes. The missing boxes can again cause the
+typesetting to be inconsistent with that with destinations enabled.
+Here again, the `nolinks' driver helps by defining `\hldest' to produce
+the empty boxes.
+
+ So, if you are planning to produce versions of your PDF document
+both with and without hyperlinks, here is the recommended way to enable
+the hyperlinks under pdfTeX:
+
+ \ifpdf
+ \enablehyperlinks
+ \else
+ \enablehyperlinks[nolinks]%
+ \fi

+
+5.5 Setting hyperlink types and options
+=======================================
+
+You can define default types for links and destinations, which will be
+used when you do not specify a type in `\hlstart' or `\hldest'.
+Similarly, you can define default values for the options; the default
+value for an option is used when you do not set the option in the
+argument to `\hlstart' or `\hldest'.
+
+ The parameters for implicit links and destinations can be customized
+by setting the "group" types and options. When not set, the defaults
+are used.
+
+ All these settings are local to the current (TeX) group, so if you
+want to set an option temporarily, you can do so inside a
+`\begingroup...\endgroup' block; when the group ends, the previous
+settings are restored.

+File: eplain.info, Node: Setting default types and options, Next: Setting group types, Up: Setting hyperlink types and options
+
+5.5.1 Setting default types and options
+---------------------------------------
+
+The default types for links and destinations can be set with the
+following commands:
+
+ \hltype{TYPE}
+ \hldesttype{TYPE}
+
+where TYPE is one of the link/destination types supported by the
+selected hyperlink driver (*note Hyperlink drivers::).
+
+ Default values for the options can be set with the following
+commands:
+
+ \hlopts{OPTIONS}
+ \hldestopts{OPTIONS}
+
+where OPTIONS is a comma-separated list of option assignments in the
+format `OPTION=VALUE'. Again, what options are allowed depends on the
+selected hyperlink driver.
+
+ Many people regard the default boxed links as not aesthetic and
+intruding on page layout. The reason why boxed links are the default is
+that the links are not colored until you load the LaTeX `color' package
+(*note Loading LaTeX packages::) or use other means to define the
+`\color' command; therefore, not producing any kind of link border may
+result in the links not being marked in any way. However, when the
+links are actually colored, there is no need to produce the link boxes
+anymore; to avoid the boxes, you can set the default border width to
+zero (if the driver you use supports the link option `bwidth'; *note
+Hyperlink drivers::):
+
+ \hlopts{bwidth=0}
+
+
+File: eplain.info, Node: Setting group types, Next: Setting group options, Prev: Setting default types and options, Up: Setting hyperlink types and options
+
+5.5.2 Setting group types
+-------------------------
+
+When called with an optional argument, as in
+
+ \hltype[GROUPS]{TYPE}
+ \hldesttype[GROUPS]{TYPE}
+
+where GROUPS is a comma-separated list of groups, `\hltype' and
+`\hldesttype' set the type for each group from GROUPS to TYPE. The
+default type is used for all groups with an empty type (this is the
+initial setting for all groups, except that the type for the `url'
+linkgroup is set to `url' by the drivers which support this link type).
+
+ There are two special "groups" which can be used inside the GROUPS
+list. An empty group sets the default type. This allows to set the
+default type and group types in one command, for example:
+
+ \hltype[eq,]{TYPE}
+
+sets the link type for the `eq' linkgroup and the default link type to
+TYPE.
+
+ Another special group is a star (`*') group, which signifies all
+defined groups. For example, the command
+
+ \hldesttype[*,]{TYPE}
+
+sets the destination type to TYPE for each group, as well as the
+default destination type.
+
+
+File: eplain.info, Node: Setting group options, Prev: Setting group types, Up: Setting hyperlink types and options
+
+5.5.3 Setting group options
+---------------------------
+
+Option values for each group are stored as a list of option
+assignments. This list does not have to contain every supported
+option. Values for options missing from this list are taken from the
+default option values.
+
+ To manipulate the list of option values for the groups, you use the
+`\hlopts' and `\hldestopts' commands with an optional argument:
+
+ \hlopts[GROUPS]{OPTIONS}
+ \hldestopts[GROUPS]{OPTIONS}
+ \hlopts![GROUPS]{OPTIONS}
+ \hldestopts![GROUPS]{OPTIONS}
+
+where GROUPS is a comma-separated list of groups and OPTIONS is a
+comma-separated list of option assignments. The two special "groups",
+the empty group and the star (`*') group, have the same meaning as for
+`\hltype' and `\hldesttype'. When used without the exclamation mark,
+`\hlopts' and `\hldestopts' preserve the current list of options for
+the groups, and only update the options listed in OPTIONS. If you add
+the exclamation mark, the current list of options for each group in
+GROUPS is discarded and the new list is set to OPTIONS.
+
+ The "overriding" nature of the `!' is appropriate when you give a
+complete specification of the options for a group, e.g., at the
+beginning of your document. On the other hand, when you want to adjust
+some option(s) and leave others intact, you should use the macros
+without the `!'.
+
+ For example, with displayed mathematical formulas, you often need to
+adjust the `raise' option for the `eq' destgroup, because the formulas
+often contain large parentheses and brackets. But when doing so, you
+want to leave the other settings unchanged. To achieve this, call
+`\hldestopts' without the `!', for example:
+
+ $$\hldestopts[eq]{raise=2.5\normalbaselineskip}
+ ...
+ $$
+
+The display commands (`$$') implicitly put the entire formula inside a
+(TeX) group (`\begingroup...\endgroup'), so you do not need to isolate
+the setting of the `raise' option--it will be restored after the
+closing `$$'.
+
+ Initially, Eplain sets the option lists for almost all groups to
+empty, so that the groups fall back on the default values for all
+options. The one exception to this rule is the `eq' destgroup, whose
+initial option list contains one setting:
+
+ raise=1.7\normalbaselineskip
+
+This setting usually accommodates the large operators, which often
+appear in displayed math.

+Links and/or destinations can be turned on or off globally by disabling

+

+
+5.6.2 Turning hyperlinks on/off for a group
+-------------------------------------------
+
+If you want to disable links/destinations produced by certain groups,
+you can give a list of the groups as an optional argument to these
+commands:
+
+ \hldeston[GROUPS]
+ \hldestoff[GROUPS]
+ \hlon[GROUPS]
+ \hloff[GROUPS]
+
+where GROUPS is the list of linkgroups/destgroups. This list can
+contain two special groups. The empty group switches the low-level
+commands (*note Turning low-level commands on/off::), and the star
+(`*') group operates on all defined groups.
+
+ Note that turning off the low-level commands disables all hyperlinks
+globally, including groups which have them enabled. Turning off certain
+linkgroups/destgroups records the fact that the macros in the group
+should not produce links/destinations. To illustrate the distinction,
+assume that all links are on; after the following sequence of commands:
+
+ \hloff
+ \hloff[eq]
+ \hlon
+
+all links are on except for the `eq' linkgroup.

+
+6.1 Slanted lines and vectors
+=============================
+
+The macros `\drawline' and `\drawvector' provide the capability found
+in LaTeX's picture mode to draw slanted lines and vectors of certain
+directions. Both of these macros take three arguments: two integer
+arguments to specify the direction of the line or vector, and one
+argument to specify its length. For example, `\drawvector(-4,1){60pt}'
+produces the vector
+
+ (A vector in the 2d quadrant of length 60 pt appears here.)
+
+ which lies in the 2d quadrant, has a slope of minus 1/4, and a width
+of 60 pt.
+
+ Note that if an `\hbox' is placed around `\drawline' or
+`\drawvector', then the width of the `\hbox' will be the positive
+dimension specified in the third argument, except when a vertical line
+or vector is specified, e.g., `\drawline(0,1){1in}', which has zero
+width. If the specified direction lies in the 1st or 2d quadrant
+(e.g., `(1,1)' or `(-2,3)'), then the `\hbox' will have positive height
+and zero depth. Conversely, if the specified direction lies in the 3d
+or 4th quadrant (e.g., `(-1,-1)' or `(2,-3)'), then the `\hbox' will
+have positive depth and zero height.
+
+ There are a finite number of directions that can be specified. For
+`\drawline', the absolute value of each integer defining the direction
+must be less than or equal to six, i.e., `(7,-1)' is incorrect, but
+`(6,-1)' is acceptable. For `\drawvector', the absolute value of each
+integer must be less than or equal to four. Furthermore, the two
+integers cannot have common divisors; therefore, if a line with slope 2
+is desired, say `(2,1)' instead of `(4,2)'. Also, specify `(1,0)'
+instead of, say, `(3,0)' for horizontal lines and likewise for vertical
+lines.
+
+ Finally, these macros depend upon the LaTeX font `line10'. If your
+site doesn't have this font, ask your system administrator to get it.
+Future enhancements will include macros to draw dotted lines and dotted
+vectors of various directions.

+6.2 Commutative diagrams
+========================
+
+The primitive commands `\drawline' and `\drawvector' can be used to
+typeset arrow theoretic diagrams. This section describes (1) macros to
+facilitate typesetting arrows and morphisms, and (2) macros to
+facilitate the construction of commutative diagrams. All macros
+described in this section must be used in math mode.

+
+
+File: eplain.info, Node: Arrows and morphisms, Next: Construction of commutative diagrams, Up: Commutative diagrams
+
+6.2.1 Arrows and morphisms
+--------------------------
+
+The macros `\mapright' and `\mapleft' produce right and left pointing
+arrows, respectively. Use superscript (`^') to place a morphism above
+the arrow, e.g., `\mapright^\alpha'; use subscript (`_') to place a
+morphism below the arrow, e.g., `\mapright_{\tilde l}'. Superscripts
+and subscripts may be used simulataneously, e.g., `\mapright^\pi_{\rm
+epimor.}'.
+
+ Similarly, the macros `\mapup' and `\mapdown' produce up and down
+pointing arrows, respectively. Use `\rt' to place a morphism to the
+right of the arrow, e.g., `\mapup\rt{\rm id}'; use `\lft' to place a
+morphism to the left of the arrow, e.g., `\mapup\lft\omega'. `\lft'
+and `\rt' may be used simultaneously, e.g., `\mapdown\lft\pi\rt{\rm
+monomor.}'.
+
+ Slanted arrows are produced by the macro `\arrow', which takes a
+direction argument (e.g., `\arrow(3,-4)'). Use `\rt' and `\lft' to
+place morphisms to the right and left, respectively, of the arrow. A
+slanted line (no arrowhead) is produced with the macro `\sline', whose
+syntax is identical to that of `\arrow'.
+
+ The length of these macros is predefined by the default TeX
+dimensions `\harrowlength', for horizontal arrows (or lines),
+`\varrowlength', for vertical arrows (or lines), and `\sarrowlength', for
+slanted arrows (or lines). To change any of these dimensions, say,
+e.g., `\harrowlength=40pt'. As with all other TeX dimensions, the
+change may be as global or as local as you like. Furthermore, the
+placement of morphisms on the arrows is controlled by the dimensions
+`\hmorphposn', `\vmorphposn', and `\morphdist'. The first two
+dimensions control the horizontal and vertical position of the morphism
+from its default position; the latter dimension controls the distance
+of the morphism from the arrow. If you have more than one morphism per
+arrow (i.e., a `^'/`_' or `\lft'/`\rt' construction), use the parameters
+`\hmorphposnup', `\hmorphposndn', `\vmorphposnup', `\vmorphposndn', `\hmorphposnrt', `\hmorphposnlft', `\vmorphposnrt', and
+`\vmorphposnlft'. The default values of all these dimensions are
+provided in the section on parameters that follows below.
+
+ There is a family of macros to produce horizontal lines, arrows, and
+adjoint arrows. The following macros produce horizontal maps and have
+the same syntax as `\mapright':
+
+`\mapright'
+ `$X\mapright Y$' = (a right arrow).
+
+`\mapleft'
+ `$X\mapleft Y$' = (a left arrow).
+
+`\hline'
+ `$X\hline Y$' = (horizontal line)
+
+`\bimapright'
+ `$X\bimapright Y$' = (two right arrows).
+
+`\bimapleft'
+ `$X\bimapleft Y$' = (two left arrows)
+
+`\adjmapright'
+ `$X\adjmapright Y$' = (two adjoint arrows; left over right)
+
+`\adjmapleft'
+ `$X\adjmapleft Y$' = (two adjoint arrows; right over left)
+
+`\bihline'
+ `$X\bihline Y$' = (two horizontal lines)
+
+ There is also a family of macros to produce vertical lines, arrows,
+and adjoint arrows. The following macros produce vertical maps and have
+the same syntax as `\mapdown':
+
+`\mapdown'
+ (a down arrow)
+
+`\mapup'
+ (an up arrow)
+
+`\vline'
+ (vertical line)
+
+`\bimapdown'
+ (two down arrows)
+
+`\bimapup'
+ (two up arrows)
+
+`\adjmapdown'
+ (two adjoint arrows; down then up)
+
+`\adjmapup'
+ (two adjoint arrows; up then down)
+
+`\bivline'
+ (two vertical lines)
+
+ Finally, there is a family of macros to produce slanted lines,
+arrows, and adjoint arrows. The following macros produce slanted maps
+and have the same syntax as `\arrow':
+
+`\arrow'
+ (a slanted arrow)
+
+`\sline'
+ (a slanted line)
+
+`\biarrow'
+ (two straight arrows)
+
+`\adjarrow'
+ (two adjoint arrows)
+
+`\bisline'
+ (two straight lines)
+
+
+ The width between double arrows is controlled by the parameter
+`\channelwidth'. The parameters `\hchannel' and `\vchannel', if
+nonzero, override `\channelwidth' by controlling the horizontal and
+vertical shifting from the first arrow to the second.
+
+ There are no adornments on these arrows to distinguish inclusions
+from epimorphisms from monomorphisms. Many texts, such as Lang's book
+`Algebra', use as a tasteful alternative the symbol `inc' (in roman)
+next to an arrow to denote inclusion.
+
+ Future enhancements will include a mechanism to draw curved arrows
+found in, e.g., the Snake Lemma, by employing a version of the `\path'
+macros of Appendix D of `The TeXbook'.

+
+6.2.2 Construction of commutative diagrams
+------------------------------------------
+
+There are two approaches to the construction of commutative diagrams
+described here. The first approach, and the simplest, treats
+commutative diagrams like fancy matrices, as Knuth does in Exercise
+18.46 of `The TeXbook'. This case is covered by the macro `\commdiag', which
+is an altered version of the Plain TeX macro `\matrix'. An example
+suffices to demonstrate this macro. The following commutative diagram
+(illustrating the covering homotopy property; Bott and Tu,
+`Differential Forms in Algebraic Topology')
+
+ (A commutative diagram appears here in the printed output.)
+
+ is produced with the code
+
+ $$\commdiag{Y&\mapright^f&E\cr \mapdown&\arrow(3,2)\lft{f_t}&\mapdown\cr
+ Y\times I&\mapright^{\bar f_t}&X}$$
+
+ Of course, the parameters may be changed to produce a different
+effect. The following commutative diagram (illustrating the universal
+mapping property; Warner, `Foundations of Differentiable Manifolds and
+Lie Groups')
+
+ (A commutative diagram appears here in the printed output.)
+
+ is produced with the code
+
+ $$\varrowlength=20pt
+ \commdiag{V\otimes W\cr \mapup\lft\phi&\arrow(3,-1)\rt{\tilde l}\cr
+ V\times W&\mapright^l&U\cr}$$
+
+ A diagram containing isosceles triangles is achieved by placing the
+apex of the triangle in the center column, as shown in the example
+(illustrating all constant minimal realizations of a linear system;
+Brockett, `Finite Dimensional Linear Systems')
+
+ (A commutative diagram appears here in the printed output.)
+
+ which is produced with the code
+
+ $$\sarrowlength=.42\harrowlength
+ \commdiag{&R^m\cr &\arrow(-1,-1)\lft{\bf B}\quad \arrow(1,-1)\rt{\bf G}\cr
+ R^n&\mapright^{\bf P}&R^n\cr
+ \mapdown\lft{e^{{\bf A}t}}&&\mapdown\rt{e^{{\bf F}t}}\cr
+ R^n&\mapright^{\bf P}&R^n\cr
+ &\arrow(1,-1)\lft{\bf C}\quad \arrow(-1,-1)\rt{\bf H}\cr
+ &R^q\cr}$$
+
+ Other commutative diagram examples appear in the file
+`commdiags.tex', which is distributed with this package.
+
+ In these examples the arrow lengths and line slopes were carefully
+chosen to blend with each other. In the first example, the default
+settings for the arrow lengths are used, but a direction for the arrow
+must be chosen. The ratio of the default horizontal and vertical arrow
+lengths is approximately the golden mean gamma=1.618...; the arrow
+direction closest to this mean is `(3,2)'. In the second example, a
+slope of -1/3 is desired and the default horizontal arrow length is 60
+pt; therefore, choose a vertical arrow length of 20 pt. You may affect
+the interline glue settings of `\commdiag' by redefining the macro
+`\commdiagbaselines'. (cf. Exercise 18.46 of `The TeXbook' and the
+section on parameters below.)
+
+ The width, height, and depth of all morphisms are hidden so that the
+morphisms' size do not affect arrow positions. This can cause a large
+morphism at the top or bottom of a diagram to impinge upon the text
+surrounding the diagram. To overcome this problem, use TeX's
+`\noalign' primitive to insert a `\vskip' immediately above or below
+the offending line, e.g.,
+`$$\commdiag{\noalign{\vskip6pt}X&\mapright^\int&Y\cr ...}'.
+
+ The macro `\commdiag' is too simple to be used for more complicated
+diagrams, which may have intersecting or overlapping arrows. A second
+approach, borrowed from Francis Borceux's `Diagram' macros for LaTeX,
+treats the commutative diagram like a grid of identically shaped boxes.
+To compose the commutative diagram, first draw an equally spaced grid,
+e.g.,
+
+ . . . . . .
+ . . . . . .
+ . . . . . .
+ . . . . . .
+
+ on a piece of scratch paper. Then draw each element (vertices and
+arrows) of the commutative diagram on this grid, centered at each grid
+point. Finally, use the macro `\gridcommdiag' to implement your design
+as a TeX alignment. For example, the cubic diagram
+
+ (A commutative diagram appears here.)
+
+ that appears in Francis Borceux's documentation can be implemented on
+a 7 by 7 grid, and is achieved with the code
+
+ $$\harrowlength=48pt \varrowlength=48pt \sarrowlength=20pt
+ \def\cross#1#2{\setbox0=\hbox{$#1$}%
+ \hbox to\wd0{\hss\hbox{$#2$}\hss}\llap{\unhbox0}}

+ E&&\mapright_k&&G\cr}$$
+
+ The dimensions `\hgrid' and `\vgrid' control the horizontal and
+vertical spacing of the grid used by `\gridcommdiag'. The default
+setting for both of these dimensions is 15 pt. Note that in the
+example of the cube the arrow lengths must be adjusted so that the
+arrows overlap into neighboring boxes by the desired amount. Hence,
+the `\gridcommdiag' method, albeit more powerful, is less automatic
+than the simpler `\commdiag' method. Furthermore, the ad hoc macro
+`\cross' is introduced to allow the effect of overlapping arrows.
+Finally, note that the positions of four of the morphisms are adjusted
+by setting `\hmorphposn' and `\vmorphposn'.
+
+ One is not restricted to a square grid. For example, the proof of
+Zassenhaus's Butterfly Lemma can be illustrated by the diagram
+(appearing in Lang's book `Algebra')
+
+ (A commutative diagram appears here.)
+
+ This diagram may be implemented on a 9 by 12 grid with an aspect
+ratio of 1/2, and is set with the code
+
+ $$\hgrid=16pt \vgrid=8pt \sarrowlength=32pt
+ \def\cross#1#2{\setbox0=\hbox{$#1$}%
+ \hbox to\wd0{\hss\hbox{$#2$}\hss}\llap{\unhbox0}}
+ \def\l#1{\llap{$#1$\hskip.5em}}
+ \def\r#1{\rlap{\hskip.5em$#1$}}
+ \gridcommdiag{&&U&&&&V\cr &&\bullet&&&&\bullet\cr
+ &&\sarrowlength=16pt\sline(0,1)&&&&\sarrowlength=16pt\sline(0,1)\cr
+ &&\l{u(U\cap V)}\bullet&&&&\bullet\r{(U\cap V)v}\cr
+ &&&\sline(2,-1)&&\sline(2,1)\cr
+ &&\cross{=}{\sline(0,1)}&&\bullet&&\cross{=}{\sline(0,1)}\cr\cr
+ &&\l{^{\textstyle u(U\cap v)}}\bullet&&\cross{=}{\sline(0,1)}&&
+ \bullet\r{^{\textstyle(u\cap V)v}}\cr
+ &\sline(2,1)&&\sline(2,-1)&&\sline(2,1)&&\sline(2,-1)\cr
+ \l{u}\bullet&&&&\bullet&&&&\bullet\r{v}\cr
+ &\sline(2,-1)&&\sline(2,1)&&\sline(2,-1)&&\sline(2,1)\cr
+ &&\bullet&&&&\bullet\cr &&u\cap V&&&&U\cap v\cr}$$
+
+ Again, the construction of this diagram requires careful choices for
+the arrow lengths and is facilitated by the introduction of the ad hoc
+macros `\cross', `\r', and `\l'. Note also that superscripts were used
+to adjust the position of the vertices u(U intersection v) and (u
+intersection V)v. Many diagrams may be typeset with the predefined
+macros that appear here; however, ingenuity is often required to handle
+special cases.

+
+7.1 Category codes
+==================
+
+Plain TeX defines `\active' (as the number 13) for use in changing
+category codes. Although the author of `The TeXbook' has
+"intentionally kept the category codes numeric", two other categories
+are commonly used: letters (category code 11) and others (12).
+Therefore, Eplain defines `\letter' and `\other'.
+
+ Sometimes it is cleaner to make a character active without actually writing
+a `\catcode' command. The `\makeactive' command takes a character as
+an argument to make active (and ignores following spaces). For
+example, here are two commands which both make `\' active:
+
+ \makeactive\\ \makeactive92
+
+ Sometimes you might want to temporarily change the category code of
+the `@' character to `\letter', so that you can use or define macros
+which are normally inaccessible to the user. For such situations,
+Eplain provides the `\makeatletter' command. It sets the category code
+of `@' to `\letter' (11) and defines `\resetatcatcode' to restore the
+category code to whatever it was before the call to `\makeatletter'.
+For example:
+
+ \makeatletter
+ \def\@hidden@macro{This macro cannot normally be
+ called / redefined by the user}
+ \resetatcatcode
+
+There is also `\makeatother' which works similarly but sets the
+category code of `@' to `\other' (12).
+
+ Usually, when you give a definition to an active character, you have
+to do so inside a group where you temporarily make the character active,
+and then give it a global definition (cf. the definition of
+`\obeyspaces' in `The TeXbook'). This is inconvenient if you are
+writing a long macro, or if the character already has a global
+definition you do not wish to transcend. Eplain provides `\letreturn',
+which defines the usual end-of-line character to be the argument. For
+example:
+
+ \def\mymacro{... \letreturn\myreturn ... }
+ \mymacro hello
+ there
+
+The end-of-line between `hello' and `there' causes `\myreturn' to be
+expanded.
+
+ `The TeXbook' describes `\uncatcodespecials', which makes all
+characters which are normally "special" into "other" characters, but
+the definition never made it into plain TeX. Eplain therefore defines
+it.
+
+ Finally, `\percentchar' expands into a literal `%' character. This
+is useful when you `\write' TeX output to a file, and want to avoid
+spurious spaces. For example, Eplain writes a `\percentchar' after the
+definition of cross-references. The macros `\lbracechar' and
+`\rbracechar' expand similarly.
+
+
+File: eplain.info, Node: Allocation macros, Next: Iteration, Prev: Category codes, Up: Programming definitions
+
+7.2 Allocation macros
+=====================
+
+Plain TeX provides macros that allocate registers of each primitive
+type in TeX, to prevent different sets of macros from using the same
+register for two different things. The macros are all named starting
+with `new', e.g., `\newcount' allocates a new "count" (integer)
+register. Such allocations are usually needed only at the top level of
+some macro definition file; therefore, plain TeX makes the allocation
+registers `\outer', to help find errors. (The error this helps to find
+is a missing right brace in some macro definition.)
+
+ Sometimes, however, it is useful to allocate a register as part of
+some macro. An outer control sequence cannot be used as part of a macro
+definition (or in a few other contexts: the parameter text of a
+definition, an argument to a definition, the preamble of an alignment,
+or in conditional text that is being skipped). Therefore, Eplain
+defines "inner" versions of all the allocation macros, named with the
+prefix `inner': `\innernewbox', `\innernewcount', `\innernewdimen', `\innernewfam', `\innernewhelp', `\innernewif', `\innernewinsert', `\innernewlanguage', `\innernewread',
+`\innernewskip', `\innernewtoks', `\innernewwrite'.
+
+ You can also define non-outer versions of other macros in the same
+way that Eplain defines the above. The basic macro is called
+`\innerdef':
+
+ \innerdef \INNERNAME {OUTERNAME}
+
+ The first argument (\INNERNAME) to `\innerdef' is the control
+sequence that you want to define. Any previous definition of
+\INNERNAME is replaced. The second argument (OUTERNAME) is the
+_characters_ in the name of the outer control sequence. (You can't use
+the actual control sequence name, since it's outer!)
+
+ If the outer control sequence is named \CS, and you want to define
+`innerCS' as the inner one, you can use `\innerinnerdef', which is just
+an abbreviation for a call to `\innerdef'. For example, these two
+calls are equivalent:
+
+ \innerdef\innerproclaim{proclaim}
+ \innerinnerdef{proclaim}
+
+
+File: eplain.info, Node: Iteration, Next: Macro arguments, Prev: Allocation macros, Up: Programming definitions
+
+7.3 Iteration
+=============
+
+You can iterate through a comma-separated list of items with `\for'. Here
+is an example:
+
+ \for\name:=karl,kathy\do{%
+ \message{\name}%
+ }%
+
+This writes `karl' and `kathy' to the terminal. Spaces before or after
+the commas in the list, or after the `:=', are _not_ ignored. To strip
+leading spaces off the items, use `\For':
+
+ \For\name:=
+ karl,
+ kathy\do{%
+ \message{\name}%
+ }%
+
+Note that trailing spaces are still _not_ ignored.
+
+ Both `\for' and `\For' expand the first token of the item list
+fully, so this is equivalent to the above:
+
+ \def\namelist{karl,kathy}%
+ \for\name:=\namelist\do ...
+
+However, this won't work, either with `\for' or with `\For':
+
+ \def\namelist{karl,kathy}%
+ \For\name:= \namelist\do ...
+
+because `\for' and `\For' expand the first token after `:=' which is
+space, not `\namelist'.
+
+ Eplain provides another kind of loops, which is an extension of plain
+TeX's `\loop'. If you say:
+
+ \loop
+ LOOP-TEXT
+ \if CONDITION
+ IF-TEXT
+ \repeat
+
+then LOOP-TEXT will be repeated as long as CONDITION is satisfied
+(`\if' can be any of the TeX's conditional commands, without the
+matching `\fi'). Eplain extends this with the optional else clause:
+
+ \loop
+ LOOP-TEXT
+ \if CONDITION
+ IF-TEXT
+ \else
+ ELSE-TEXT
+ \repeat
+
+Here, LOOP-TEXT will be repeated as long as CONDITION is _not_
+satisfied. This extension is from Victor Eijkhout's TeX by Topic
+(page 104).
+
+
+File: eplain.info, Node: Macro arguments, Next: Converting to characters, Prev: Iteration, Up: Programming definitions
+
+7.4 Macro arguments
+===================
+
+It is occasionally useful to redefine a macro that takes arguments to
+do nothing. Eplain defines `\gobble', `\gobbletwo', and `\gobblethree'
+to swallow one, two, and three arguments, respectively.
+
+ For example, if you want to produce a "short" table of contents--one
+that includes only chapters, say--the easiest thing to do is read the
+entire `.toc' file (*note Contents::), and just ignore the commands
+that produce section or subsection entries. To be specific:
+
+ \let\tocchapterentry = \shorttocchapter
+ \let\tocsectionentry = \gobbletwo
+ \let\tocsubsectionentry = \gobbletwo
+ \readtocfile
+
+(Of course, this assumes you only have chapters, sections, and
+subsections in your document.)
+
+ In addition, Eplain defines `\eattoken' to swallow the single
+following token, using `\let'. Thus, `\gobble' followed by `{...}'
+ignores the entire brace-enclosed text. `\eattoken' followed by the
+same ignores only the opening left brace.
+
+ Eplain defines a macro `\identity' which takes one argument and
+expands to that argument. This may be useful if you want to provide a
+function for the user to redefine, but don't need to do anything by
+default. (For example, the default definition of `\eqconstruct' (*note
+Formatting equation references::) is `\identity'.)
+
+ You may also want to read an optional argument. The established
+convention is that optional arguments are put in square brackets, so
+that is the syntax Eplain recognizes. Eplain ignores space tokens
+before an optional argument, via `\futurenonspacelet'.
+
+ You test for an optional argument by using `\@getoptionalarg'. It
+takes one argument, a control sequence to expand after reading the
+argument, if present. If an optional argument is present, the control
+sequence `\@optionalarg' expands to it; otherwise, `\@optionalarg' is
+`\empty'. You must therefore have the category code of `@' set to 11
+(letter). Here is an example:
+
+ \catcode`@=\letter
+ \def\cmd{\@getoptionalarg\finishcmd}
+ \def\finishcmd{%
+ \ifx\@optionalarg\empty
+ % No optional argument present.
+ \else
+ % One was present.
+ \fi
+ }
+
+ If an optional argument contains another optional argument, the inner
+one will need to be enclosed in braces, so TeX does not mistake the end
+of the first for the end of the second.
+
+
+File: eplain.info, Node: Converting to characters, Next: Expansion, Prev: Macro arguments, Up: Programming definitions
+
+7.5 Converting to characters
+============================
+
+Eplain defines `\xrlabel' to produce control sequence names for
+cross-reference labels, et al. This macro expands to its argument with
+an `_' appended. (It does this because the usual use of `\xrlabel' is
+to generate a control sequence name, and we naturally want to avoid
+conflicts between control sequence names.)
+
+ Because `\xrlabel' is fully expandable, to make a control sequence
+name out of the result you need only do
+
+ `\csname \xrlabel{LABEL}\endcsname'
+
+The `\csname' primitive makes a control sequence name out of any
+sequence of character tokens, regardless of category code. Labels can
+therefore include any characters except for `\', `{', `}', and `#', all
+of which are used in macro definitions themselves.
+
+ `\sanitize' takes a control sequence as an argument and converts the
+expansion of the control sequence into a list of character tokens.
+This is the behavior you want when writing information like chapter
+titles to an output file. For example, here is part of the definition
+of `\writenumberedtocentry'; `#2' is the title that the user has given.
+
+ ...
+ \def\temp{#2}%
+ ...
+ \write\tocfile{%
+ ...
+ \sanitize\temp
+ ...
+ }%

+
+7.6.1 `\csn' and `\ece'
+-----------------------
+
+`\csn'{NAME} simply abbreviates `\csname' NAME `\endcsname', thus
+saving some typing. The extra level of expansion does take some time,
+though, so I don't recommend it for an inner loop.
+
+ `\ece'{TOKEN}{NAME} abbreviates
+
+ \expandafter TOKEN \csname NAME \endcsname
+
+For example,
+
+ \def\fontabbrevdef#1#2{\ece\def{@#1font}{#2}}
+ \fontabbrevdef{normal}{ptmr}
+
+defines a control sequence `\@normalfont' to expand to `ptmr'.
+
+
+File: eplain.info, Node: \edefappend, Next: Hooks, Prev: \csn and \ece, Up: Expansion
+
+7.6.2 `\edefappend'
+-------------------
+
+`\edefappend' is a way of adding on to an existing definition. It
+takes two arguments: the first is the control sequence name, the second
+the new tokens to append to the definition. The second argument is
+fully expanded (in the `\edef' that redefines the control sequence).
+
+ For example:
+
+ \def\foo{abc}
+ \def\bar{xyz}
+ \edefappend\foo{\bar karl}
+
+results in `\foo' being defined as `abcxyzkarl'.
+
+
+File: eplain.info, Node: Hooks, Next: Properties, Prev: \edefappend, Up: Expansion
+
+7.6.3 Hooks
+-----------
+
+A "hook" is simply a name for a group of actions which is executed in
+certain places--presumably when it is most useful to allow
+customization or modification. TeX already provides many builtin
+hooks; for example, the `\every ...' token lists are all examples of
+hooks.
+
+ Eplain provides several macros for adding actions to hooks. They all
+take two arguments: the name of the hook and the new actions.
+
+`hookaction NAME ACTIONS'
+`hookappend NAME ACTIONS'
+
+`hookprepend NAME ACTIONS'
+ Each of these adds ACTIONS to the hook NAME. (Any
+ previously-defined actions are retained.) NAME is not a control
+ sequence, but rather the characters of the name.
+
+`hookactiononce NAME `\CS''
+ `\hookactiononce' adds CS to NAME, like the macros above, but
+ first it adds
+
+ \global\let \CS \relax
+
+ to the definition of \CS. (This implies \CS must be a true
+ expandable macro, not a control sequence `\let' to a primitive or
+ some other such thing.) Thus, \CS is expanded the next time the
+ hook NAME is run, but it will disappear after that.
+
+ The `\global' is useful because `\hookactiononce' is most useful
+ when the grouping structure of the TeX code could be anything.
+ Neither this nor the other hook macros do global assignments to
+ the hook variable itself, so TeX's usual grouping rules apply.
+
+ The companion macro to defining hook actions is `\hookrun', for
+running them. This takes a single argument, the name of the hook. If
+no actions for the hook are defined, no error ensues.
+
+ Here is a skeleton of general `\begin' and `\end' macros that run
+hooks, and a couple of calls to define actions. The use of
+`\hookprepend' for the begin action and `\hookappend' for the end
+action ensures that the actions are executed in proper sequence with
+other actions (as long as the other actions use `\hookprepend' and
+`\hookappend' also).
+
+ \def\begin#1{ ... \hookrun{begin} ... }
+ \def\end#1{ ... \hookrun{end} ... }
+ \hookprepend{begin}\start_underline
+ \hookappend{end}\finish_underline
+
+
+File: eplain.info, Node: Properties, Next: \expandonce, Prev: Hooks, Up: Expansion
+
+7.6.4 Properties
+----------------
+
+A "property" is a name/value pair associated with another symbol,
+traditionally called an "atom". Both atom and property names are
+control sequence names.
+
+ Eplain provides two macros for dealing with property lists:
+`\setproperty' and `\getproperty'.
+
+`\setproperty ATOM PROPNAME VALUE'
+ `\setproperty' defines the property PROPERTY on the atom ATOM to
+ be VALUE. ATOM and PROPNAME can be anything acceptable to
+ `\csname'. VALUE can be anything.
+
+`\getproperty ATOM PROPNAME'
+ `\getproperty' expands to the value stored for PROPNAME on ATOM.
+ If PROPNAME is undefined, it expands to nothing (i.e., `\empty').
+
+
+ The idea of properties originated in Lisp (I believe). There, the
+implementation truly does associate properties with atoms. In TeX,
+where we have no builtin support for properties, the association is only
+conceptual.
+
+ The following example typesets `xyz'.
+
+ \setproperty{a}{pr}{xyz}
+ \getproperty{a}{pr}
+
+
+File: eplain.info, Node: \expandonce, Next: \ifundefined, Prev: Properties, Up: Expansion
+
+7.6.5 `\expandonce'
+-------------------
+
+`\expandonce' is defined as `\expandafter\noexpand'. Thus,
+`\expandonce TOKEN' expands TOKEN once, instead of to TeX primitives.
+This is most useful in an `\edef'.
+
+ For example, the following defines `\temp' to be `\foo', not `abc'.
+
+ \def\foo{abc}
+ \def\bar{\foo}
+ \edef\temp{\expandonce\bar}
+
+
+File: eplain.info, Node: \ifundefined, Next: \ifempty, Prev: \expandonce, Up: Expansion
+
+7.6.6 `\ifundefined'
+--------------------
+
+`\ifundefined{CS} T \else F \fi' expands the T text if the control
+sequence `\CS' is undefined or has been `\let' to `\relax', and the F
+text otherwise.
+
+ Since `\ifundefined' is not a primitive conditional, it cannot be
+used in places where TeX might skip tokens "at high speed", e.g.,
+within another conditional--TeX can't match up the `\if''s and `\fi''s.
+
+ This macro was taken directly from `The TeXbook', page 308.
+
+
+File: eplain.info, Node: \ifempty, Next: \ifinteger and \isinteger, Prev: \ifundefined, Up: Expansion
+
+7.6.7 `\ifempty'
+----------------
+
+`\ifempty{ARG} T \else F \fi' expands the T text if ARG is the empty
+string, and the F text otherwise. This macro is useful when you need
+to test for empty arguments to your macros, for example:
+
+ \def\foo#1{\ifempty{#1} T \else F \fi}
+
+ Since `\ifempty' is not a primitive conditional, it cannot be used
+in places where TeX might skip tokens "at high speed", e.g., within
+another conditional--TeX can't match up the `\if''s and `\fi''s.
+
+ Note that the following code
+
+ \def\empty{}
+ \ifempty\empty\message{empty}\else\message{not empty}\fi
+
+will produce the message `not empty'.
+
+
+File: eplain.info, Node: \ifinteger and \isinteger, Next: \futurenonspacelet, Prev: \ifempty, Up: Expansion
+
+7.6.8 `\ifinteger' and `\isinteger'
+-----------------------------------
+
+`\ifinteger{ARG} T \else F \fi' expands the T text if ARG is an
+integer, and the F text otherwise. This macro can detect positive and
+negative integers.
+
+ Since `\ifinteger' is not a primitive conditional, it cannot be used
+in places where TeX might skip tokens "at high speed", e.g., within
+another conditional--TeX can't match up the `\if''s and `\fi''s. For
+such situations Eplain provides `\isinteger', which can be used as
+follows:
+
+ \if\isinteger{ARG} T \else F \fi
+
+ Although `\ifinteger' and `\isinteger' work well with regular input,
+they are not bullet-proof. For example, the following code
+
+ \ifinteger{12_ab}integer\else not integer\fi
+
+will expand to `ab_integer' (and thus would not even compile outside
+math mode).
+
+ These macros come from TeX Frequently Asked Question
+(`http://www.tex.ac.uk/cgi-bin/texfaq2html').
+
+
+File: eplain.info, Node: \futurenonspacelet, Prev: \ifinteger and \isinteger, Up: Expansion
+
+7.6.9 `\futurenonspacelet'
+--------------------------
+
+The `\futurelet' primitive allows you to look at the next token from
+the input. Sometimes, though, you want to look ahead ignoring any
+spaces. This is what `\futurenonspacelet' does. It is otherwise the
+same as `\futurelet': you give it two control sequences as arguments,
+and it assigns the next nonspace token to the first, and then expands
+the second. For example:
+
+ \futurenonspacelet\temp\finishup
+ \def\finishup{\ifx\temp ...}
+
+
+File: eplain.info, Node: Obeying spaces, Next: Writing out numbers, Prev: Expansion, Up: Programming definitions
+
+7.7 Obeying spaces
+==================
+
+`\obeywhitespace' makes both end-of-lines and space characters in the
+input be respected in the output. Unlike plain TeX's `\obeyspaces',
+even spaces at the beginnings of lines turn into blank space.
+
+ By default, the size of the space that is produced by a space
+character is the natural space of the current font, i.e., what `\ '
+produces.
+
+ Ordinarily, a blank line in the input produces as much blank vertical
+space as a line of text would occupy. You can adjust this by assigning
+to the parameter `\blanklineskipamount': if you set this negative, the
+space produced by a blank line will be smaller; if positive, larger.
+
+ Tabs are not affected by this routine. In particular, if tabs occur
+at the beginning of a line, they will disappear. (If you are trying to
+make TeX do the "right thing" with tabs, don't. Use a utility program
+like expand instead.)

+7.8 Writing out numbers
+=======================
+
+`\numbername' produces the written-out form of its argument, i.e.,
+`zero' through `ten' for the numbers 0-10, and numerals for all others.
+
+
+File: eplain.info, Node: Mode-specific penalties, Next: Auxiliary files, Prev: Writing out numbers, Up: Programming definitions
+
+7.9 Mode-specific penalties
+===========================
+
+TeX's built-in `\penalty' command simply appends to the current list,
+no matter what kind of list it is. You might intend a particular
+penalty to always be a "vertical" penalty, however, i.e., appended to a
+vertical list. Therefore, Eplain provides `\vpenalty' and `\hpenalty'
+which first leave the other mode and then do `\penalty'.
+
+ More precisely, `\vpenalty' inserts `\par' if the current mode is
+horizontal, and `\hpenalty' inserts `\leavevmode' if the current mode
+is vertical. (Thus, `\vpenalty' cannot be used in math mode.)
+
+

+
+7.10 Auxiliary files
+====================
+
+It is common to write some information out to a file to be used on a
+subsequent run. But when it is time to read the file again, you only
+want to do so if the file actually exists. `\testfileexistence' is
+given an argument which is appended to `\jobname', and sets the
+conditional `\iffileexists' appropriately. For example:
+
+ \testfileexistence{toc}%
+ \iffileexists
+ \input \jobname.toc
+ \fi
+
+ `\testfileexistence' takes an optional parameter; when given, it
+will override `\jobname' for the root part of the file name. For
+example, if you want to test for the file `answers.aux', you can do
+this with the following:
+
+ \testfileexistence[answers]{aux}%
+ \iffileexists
+ \input answers.aux
+ \fi
+
+
+File: eplain.info, Node: User-defined environments, Next: Page list and page range parsers, Prev: Auxiliary files, Up: Programming definitions
+
+7.11 User-defined environments
+==============================
+
+Plain TeX does not provide "named" block structures, only the anonymous
+`\begingroup' and `\endgroup' pair. The disadvantage of this is that
+when there are several such groups and one is mismatched, it can be
+difficult to find the error. Eplain provides a named block structure so
+that if you forget an `\environment' or an `\endenvironment', you will
+(probably) get an error message about it.
+
+ For example:
+
+ \def\itpar{
+ \environment{@italicpar}
+ \it\par
+ }
+ \def\enditpar{
+ \par
+ \endenvironment{@italicpar}%
+ }
+
+which could then be used to set italicized paragraphs:
+
+ \itpar
+ If I reprehend anything in this world, it is the use of my oracular
+ tongue, and a nice derangement of epitaphs!
+ \enditpar
+
+ The above sort of environment allows nesting. But environments
+shouldn't always be allowed to nest. Put the control sequence
+`\checkenv' at the beginning of a macro that is going to define an
+environment that should not be nested.
+
+
+File: eplain.info, Node: Page list and page range parsers, Prev: User-defined environments, Up: Programming definitions
+
+7.12 Page list and page range parsers
+=====================================
+
+The macros which Eplain uses to parse the page lists and ranges in the
+index, `\idxparselist' and `\idxparserange' (*note Page destinations
+for index terms::), are sometimes useful when defining page number
+encapsulators. They take one argument, text to parse. When a page
+list (range) is not present, they set `\idxpagei' to be `\empty'; when
+a list (range) is detected, they set `\idxpagei' and `\idxpageii' to
+the first and the second page numbers, respectively.
+
+ Eplain's defaults for the page list and page range delimiters are the
+same as those in MakeIndex, a comma followed by a space (`, ') and two
+dashes (`--'), respectively. If you customize MakeIndex to use
+different delimiters, you must not forget to let Eplain know about them
+with the commands
+
+ \setidxpagelistdelimiter{LIST-DELIM}
+ \setidxpagerangedelimiter{PAGE-DELIM}
+
+These commands save the LIST-DELIM and PAGE-DELIM delimiters in `\idxpagelistdelimiter'
+and `\idxpagerangedelimiter', respectively.
+
+ For example, you may want to define a page number markup command
+which italicizes and properly underlines page ranges by underlining
+only the page numbers and not the delimiter:
+
+ \def\ituline#1{%
+ {\it
+ \idxparserange{#1}%
+ \ifx\idxpagei\empty
+ % The argument is a single page number.
+ \underbar{#1}%
+ \else
+ % The argument is a page range.
+ \underbar{\idxpagei}\idxpagerangedelimiter\underbar{\idxpageii}%
+ \fi}%
+ }
+
+Note that the `\ituline' macro is not aware of page lists. This is not
+needed if you use hyperlinks in the index, because `\hlidx' and
+`\hlidxpage' will break up the page lists before calling the user's
+page encapsulator (*note Page destinations for index terms::), so
+`\ituline' will never see the lists. If, however, you need to design a
+macro which also takes care of the lists, you can extend `\ituline'
+with an additional call to `\idxparselist'.

+8.1 Hyperlinks (`xhyper.tex')
+=============================
+
+% (This file is public domain.)
+%
+% This file demonstrates the following features of Eplain:
+%
+% - explicit and implicit hyperlinks;
+% - symbolic cross-references;
+% - inserting external graphics using |\includegraphics| from
+% the \LaTeX\ package |graphicx.sty|.
+% - rotating text using |\rotatebox| from |graphicx.sty|.
+%
+% The compiled demo can be downloaded from
+%
+% http://tug.org/eplain/demo
+%
+% In order to compile this file yourself, you will need the CTAN lion
+% drawing by Duane Bibby from
+%
+% ftp://tug.ctan.org/ftpmaint/CTAN_lion/ctan_lion_350x350.png
+%
+% (thanks, |www.ctan.org|). Place the image file in the same
+% directory with this file, and change to that directory. Now, to
+% produce a PDF, run twice the command
+%
+% pdftex xhyper.tex
+%
+% During the first run, Eplain will write the information about the
+% cross-references into |xhyper.aux|, and during the second run this
+% information will be read by Eplain to typeset the references.
+%
+% Demo case:
+%
+% Suppose you are using pdf\TeX, have a figure you want to insert
+% scaled to $200\,pt$ horizontally, and you want this figure to
+% completely fill the PDF viewer's window whenever the reader
+% selects a link pointing to this figure. Additionally, you want to
+% typeset some text as live hyperlinks, clicking on which will start
+% a Web browser and open a URL.
+
+\input eplain
+
+% Load \LaTeX\ packages.
+\beginpackages
+ % |url.sty| provides the |\url| command which we will use to typeset
+ % a URL. We request that |url.sty| be the version from June~27,
+ % 2005, or later, because earlier versions had problems interacting
+ % with plain \TeX.
+ \usepackage{url}[2005/06/27]
+ % |color.sty| provides support for colored text; all hyperlinks are
+ % automatically colored by Eplain when this package is loaded. We give
+ % the |dvipsnames| option because we want to use named colors from the
+ % |dvips| graphics driver.
+ \usepackage[dvipsnames]{color}
+ % Finally, we load |graphicx.sty|, for the macros |\includegraphics|
+ % and |\rotatebox|.
+ \usepackage{graphicx}
+\endpackages
+
+% Remember that hyperlinks are off by default. Therefore, we need to
+% enable them.
+\enablehyperlinks
+
+% Customize some hyperlink options. First, we set border width to~$0$
+% for all links to get rid of the default boxes around links (we
+% prefer colored links over the boxed links). Next, we say that all
+% links created by the |url| hyperlink group (which means the |\url|
+% command from |url.sty|) must be colored using the named color
+% |BlueViolet|.
+\hlopts{bwidth=0}
+\hlopts[url]{colormodel=named,color=BlueViolet}
+
+% Inhibit page numbering (we have only one page).
+\nopagenumbers
+
+% Define a class word for the cross-reference class |figure|. This
+% word, when defined, will be automatically prepended by Eplain to the
+% reference created by |\ref| (read on to see its use).
+\def\figureword{fig.}
+
+% Allocate a count register for the figure's number, and a box
+% register which we'll use to measure dimensions of the image.
+\newcount\fignumber
+\newbox\imgbox
+
+% Now comes the fun part--constructing the figure for the image of the
+% \CTAN\ lion. We define a macro
+%
+% \fig{LABEL}{FILENAME}{CAPTION}{WIDTH}
+%
+% which creates a figure using LABEL for the cross-reference and
+% hyperlink label, reading the image from file FILENAME, using CAPTION
+% to name the figure, and WIDTH to scale the image horizontally.
+\def\fig#1#2#3#4{%
+ % Leave some space above the figure. This will also ensure that we
+ % are in the vertical mode before we produce a |\vbox|.
+ \medskip
+ % Advance the figure number. |\global| ensures that the change to
+ % the count register is global, even when |\fig| is buried inside a
+ % group.
+ \global\advance\fignumber by 1
+ % We use |\includegraphics| (from |graphicx.sty|) to load the image,
+ % scaled to the specified width, into our ``measuring'' box
+ % |\imgbox|.
+ \setbox\imgbox = \hbox{\includegraphics[width=#4]{#2}}%
+ % To make the demo even more exciting, let's put the figure's
+ % caption to the left of the image into the |\indent| space of the
+ % new paragraph, and rotate the caption~$90^\circ$.
+ \textindent{%
+ \rotatebox{90}{F{\sc IGURE}~\the\fignumber. #3}%
+ }%
+ % Continue the paragraph by constructing a |\vbox| with the image of
+ % the lion. We use |\definexref| to define the cross-reference
+ % label.
+ \vbox{%
+ % In addition to the cross-reference label, |\definexref| will
+ % create a hyperlink destination with the same label. Therefore,
+ % we customize this destination to do what we need. We say that
+ % destination type for the hyperlink group |definexref| (to which
+ % |\definexref| belongs) should be |fitr|. This destination type
+ % will magnify the rectangle specified by the options |width|,
+ % |height| and |depth| to the PDF viewer's window. Therefore, we
+ % set those options accordingly with |\hldestopts| (notice the use
+ % of |depth| instead of |height|---we will want the rectangle to
+ % extend {\it downward}, to cover the image which will come
+ % next). Notice that these settings will be isolated within the
+ % current group (i.e., the |\vbox| we're constructing).
+ \hldesttype[definexref]{fitr}%
+ \hldestopts[definexref]{width=\wd\imgbox,height=0pt,depth=\ht\imgbox}%
+ % We define a symbolic label so that we can later refer
+ % to the figure with |\ref|. The command |\definexref| does
+ % exactly that. The last argument to |\definexref| specifies
+ % class of the label, which determines the word used by |\ref| in
+ % front of the reference text (remember that we've defined
+ % |\figureword| above).
+ \definexref{#1}{\the\fignumber}{figure}%
+ % Finally, produce the image which we've been stashing in the box
+ % register |\imgbox|.
+ \box\imgbox
+ }%
+ \medskip
+}
+
+% Create the figure.
+\fig{CTANlion}{ctan_lion_350x350}{Lion in the archives}{200pt}
+
+% Finished with the fun part, we can relax and typeset some
+% hyperlinks. The easiest way to do that is to use the |\ref|
+% cross-reference command. We can even pass an optional argument
+% (|the lion in|), which will be placed before the class word (|fig.|)
+% and become part of the link (to make sure the reader does not have
+% to aim too hard).
+Show me \ref[the lion in]{CTANlion}.
+
+% If you are the restless kind, here's another way to create a
+% hyperlink to the image: we create a link explicitly by using
+% |\hlstart ... \hlend|. We don't specify the link type, therefore
+% the default type |name| will be used (these are ``named links'',
+% i.e., links pointing to destinations identified by labels). In the
+% options argument, we specify that the border of the link should be
+% inverted when the user clicks the link (|hlight=O|), and also set
+% special color for this link, overriding the default dark-red. The
+% label for the destination is the same as the cross-reference label,
+% |CTANlion|.
+Show me
+\hlstart{}{hlight=O,colormodel=named,color=OliveGreen}{CTANlion}
+ the CTAN lion\hlend.
+
+% Let's now point somewhere outside our document. Eplain homepage is
+% a good target. In the similar spirit, let's consider two
+% approaches. The easy one is to use the |\url| command from
+% |url.sty|. Remember that we have customized the color of |url|
+% hyperlinks, so this one will show up with a different color than the
+% default dark-red.
+Take me to \url{http://tug.org/eplain}.
+
+% The second approach is to create an explicit URL link. We specify
+% yet another border highlighting mode, |P|, which means that the
+% region underneath the bounding box of the link will be drawn inset
+% into the page. Also, let's set the color of the hyperlink to an RGB
+% color |0.4,0.1,0.4|. Since we cannot use commas to separate the
+% color elements inside the options parameter to |\hlstart| (commas
+% there separate options), we have to first create a user-defined
+% color with |\definecolor| from |color.sty|, and use that in
+% |\hlstart|.
+\definecolor{mycolor}{rgb}{0.4,0.1,0.4}
+
+Take me to
+\hlstart{url}{hlight=P,colormodel=,color=mycolor}{http://tug.org/eplain}
+ Eplain homepage\hlend.

+8.2 Highlighting TeX comments in listings (`lscommnt.tex')
+==========================================================
+
+% (This file is public domain.)
+% Demonstrate how Eplain can be used to include a TeX source file
+% verbatim, typesetting comments in colored italic typewriter type.
+
+% Load Eplain and LaTeX's color.sty package.
+\input eplain
+\beginpackages \usepackage{color} \endpackages
+\nopagenumbers % Disable page numbers.
+\font\commentfont = cmitt10 % Font for the comments (italic \tt).
+% We'll define some `protected' macros with `@' in their names.
+\makeatletter
+% Define an equivalent of Eplain's \letreturn, to be able to assign
+% various actions to the (active) percent character.
+\begingroup \makeactive\%
+ \gdef\letpercent{\let%}
+\endgroup
+% The listing hook to be called in \setuplistinghook, see below. It
+% makes `%' active and assigns it a `start comment' action.
+\def\hlightcommentslisting{\makeactive\% \letpercent\start@comment}%
+% This is what `%' is aliased to before a comment is started.
+\def\start@comment{%
+ \leavevmode % Needed in the very first line of the input to process
+ % the new par (possibly inserting line number) before we
+ % kick in with the color and stuff.
+ \begingroup % Isolate color and font changes and the redefinitions.
+ \commentfont
+ \color[cmyk]{0.28,1,1,0.35}%
+ \percentchar % Produce the actual `%' and
+ \letpercent\percentchar % make all following `%'s do the same.
+ \letreturn\end@comment % Call \end@comment at end-of-line.
+}
+% \end@comment (alias for ^^M inside a comment) will end the comment
+% started by \start@comment. We make ^^M active temporarily so that
+% the active version of ^^M gets "frozen" into \end@comment.
+\begingroup \makeactive\^^M % Avoid ^^M's from here on.
+ \gdef\end@comment{\endgroup ^^M}%
+\endgroup
+\resetatcatcode % Make `@' again inaccessible for use in macro names.
+
+% Define \setuplistinghook to setup comments highlighting, line
+% numbering and omitting the last (empty) line of input.
+\def\setuplistinghook{\hlightcommentslisting \linenumberedlisting
+ \nolastlinelisting}
+% Isn't this fun? This file typesets itself, with the extra bonus of
+% the pretty-printed comments and numbered source lines!

+# This script filters input lines (which are expected to be a list of
+# `\indexentry' lines for MakeIndex) eliminating matching lines. The comparison
+# is done without regard to hyperlink label names (in the form `IDX*', where `*'
+# stands for a non-negative integer).
+
+# This has to be done to avoid terms which differ only in hyperlink label names
+# embedded into them, because MakeIndex will treat these otherwise identical
+# terms as distinct, listing more than once a page number for equivalent terms
+# on the same page.
+
+# `stripped' array is indexed by `\indexentry' lines stripped off the hyperlink
+# label name. For each term, we use its stripped version as a key into the
+# `stripped' array to increment its element. This records the fact that we have
+# seen the term with such key. Also, we add the (full) `\indexentry' line to
+# the `terms' array, but only if we have not yet seen a term with such key.
+
+# The idea was borrowed from Edition 3 of `GAWK: Effective AWK Programming: A
+# User's Guide for GNU Awk', which contains the following credit:
