@@ -20,34 +20,20 @@ Installation
Building the savetrees package is fairly straightforward:
- latex savetrees.ins <= Extract savetrees.sty, savetrees.bst,
- and makethin.pl.
+ latex savetrees.ins <= Extract savetrees.sty and savetrees.bst.
latex savetrees.dtx <= Build the documentation (savetrees.dvi).
makeindex -s gind.ist savetrees <= Generate an index (makeindex.ind).
latex savetrees.dtx <= Add the index to the documentation.
-Then, on Unix:
-
- mv makethin.pl makethin <= Drop the unnecessary .pl extension.
- chmod +x makethin <= Make the Perl script executable.
-
To install savetrees, move savetrees.sty into a directory searched by
LaTeX (e.g., .../texmf/tex/latex/misc/) and move savetrees.bst into a
directory searched by BibTeX (e.g., .../texmf/bibtex/bst/misc/).
-If you have both Perl and a Kpathsea-based TeX distribution -- i.e.,
-you have a "kpsewhich" command -- then you should additionally install
-the makethin script somewhere in your path (e.g., /usr/local/bin). On
-a Unix system you can produce a man page using a command like the
-following:
-
- makethin --man=/usr/local/man/man1/makethin.1

-
-
-=head1 DESCRIPTION
-
-B<makethin> produces thinner versions of PostScript fonts for use with
-TeX/LaTeX and Dvips. More precisely, it finds all of the F<.tfm>
-and F<.vf> fonts referred to by a F<.dvi> file, scales the
-character-width metrics by a given amount, and writes new F<.tfm> and
-F<.vf> files to the current directory. B<makethin> then generates a
-customized F<.map> and F<config> file for Dvips and, optionally, a
-customized F<pdftex.cfg> file for pdfLaTeX.
-
-The general procedure for using B<makethin> is as follows:
-
-=over 4
-
-=item 1.
-
-Run B<latex> on your F<.tex> source file to produce a F<.dvi> file.
-
-=item 2.
-
-Run B<makethin> on the F<.dvi> file to create new F<.tfm>, F<.vf>,
-F<.map>, and F<config> files.
-
-=item 3.
-
-Re-run B<latex> on your F<.tex> source file to typeset it with the new
-fonts.
-
-=item 4.
-
-Run B<dvips> on the F<.dvi> file, specifying the newly generated
-F<.map> and F<config> files, to produce a F<.ps> file.
-
-=back
-
-
-=head1 OPTIONS
-
-The following are the command-line options that B<makethin> accepts:
-
-=over 4
-
-=item B<-v>, B<--verbose>
-
-Increase the verbosity of the status output. B<--verbose> can be
-specified multiple times on the same command line, with each
-B<--verbose> futher increasing the verbosity. (Currently, two
-B<--verbose>s have maximal impact.)
-
-=item B<-h>, B<--help>
-
-Display basic usage information. When combined with B<--verbose>,
-additionally describes each of the command-line options. When
-combined with a second B<--verbose>, B<--help> outputs the complete
-B<makethin> manual page.
-
-=item B<-x> I<factor>, B<--xscale>=I<factor>
-
-Scale fonts horizontally by a factor of I<factor>. The default,
-C<0.5>, produces nearly illegible fonts but is useful for verifying
-that B<makethin> actually worked. Factors of C<0.90>-C<0.99> are more
-reasonable.
-
-=item B<-C>, B<--cleanfirst>
-
-Delete all files generated by a previous run of B<makethin> before
-generating new ones.
-
-=item B<-c>, B<--clean>
-
-Delete all files generated by a previous run of B<makethin> and then
-exit.
-
-=item B<-P> I<extension>, B<--config>=I<extension>
-
-Process all of the F<.map> files named in F<config.>I<extension>
-(found in Dvips's configuration directory). B<--config> can be
-specified multiple times on the same command line. F<config.ps> is
-processed implicitly. The same B<-P> arguments that you would
-normally pass to B<dvips> to utilize entirely PostScript fonts (e.g.,
-B<-Pcmz> and B<-Pamz>) should also be passed to B<makethin>.
-
-=item B<-p>, B<--pdftex>
-
-In addition to producing the files needed by Dvips, also produce a
-F<pdftex.cfg> file that is usable by pdfLaTeX.
-
-=item B<-m> I<file>[,I<file>]...], B<--extramaps>=I<file>[,I<file>]...]
-
-Additionally process the named Dvips F<.map> files even if they're
-not referred to by any of the F<config.>I<extension> files specified
-with B<--config>. B<--extramaps> can be specified multiple times on
-the same command line.
-
-=item B<-k> I<font>[,I<font>]...], B<--skipfonts>=I<font>[,I<font>]...]
-
-Don't make thin versions of the named fonts, even if they're listed in
-the F<.dvi> file. Fonts are named using the Berry scheme (i.e.,
-``C<pcrr8a>'' as opposed to ``C<COURB>'' or ``C<Courier-Bold>'').
-B<--skipfonts> can be specified multiple times on the same command
-line.
-
-=item B<-b> I<string>, B<--basename>=I<string>
-
-Tell B<makethin> to use I<string> as the base name for the Dvips
-configuration files it generates. The default is ``C<thin>'', so
-B<makethin> normally produces files named F<config.thin> and
-F<thin.map>, but B<--basename> enables alternate filenames to be used.
-
-=item B<-e> I<font>[,I<font>]...], B<--extrafonts>=I<font>[,I<font>]...]
-
-Make thin versions of the named fonts, even if they're not listed in
-the F<.dvi> file. Fonts are named using the Berry scheme (i.e.,
-``C<pcrr8a>'' as opposed to ``C<COURB>'' or ``C<Courier-Bold>'').
-B<--extrafonts> can be specified multiple times on the same command
-line.
-
-=item B<--man>=I<man page>
-
-Create a Unix manual page for B<makethin> in the standard, *roff
-format. Typical usage is:
-
- makethin --man=/usr/man/man1/makethin.1
-
-=item B<--man-ps>=I<PostScript file>
-
-Create a Unix manual page for B<makethin> in PostScript format instead
-of *roff format.
-
-=back
-
-In addition to the options listed above, B<makethin> has a required
-argument, which is the name of a F<.dvi> file from which to read font
-information.
-
-
-=head1 EXAMPLES
-
-The following are some examples of how to use B<makethin>.
-
-=head2 A typical case
-
-First, we need to produce F<myfile.dvi>, because that contains the
-font information that B<makethin> will read:
-
- latex myfile.tex
-
-Next, we invoke B<makethin>, telling it to process F<config.cmz>
-(which, in turn, causes F<psfonts.cmz> to be processed), This tells
-B<makethin> to use PostScript versions of the Computer Modern fonts
-instead of bitmapped versions. (B<makethin> can scale only PostScript
-fonts.) We also specify maximal verbosity:
-
- makethin -Pcmz --verbose --verbose myfile.dvi
-
-The preceding line reads F<config.ps>, F<config.cmz>, various map
-files, such as F<psfonts.map> and F<psfonts.cmz>, and all of the
-F<.tfm> and F<.vf> files mentioned in F<myfile.dvi>. It then writes
-F<config.thin>, F<thin.map>, and modified versions of all of the
-F<.tfm> and F<.vf> files to the current directory.
-
-We now need to re-run B<latex>, so it can produce a new F<myfile.dvi>
-using the thinner metrics listed in the current directory's F<.tfm>
-and F<.vf> files:
-
- latex myfile.tex
-
-Finally, we produce a PostScript file using the newly generated using
-F<config.thin> and F<thin.map> files:
-
- dvips -Pthin myfile.dvi -o myfile.ps
-
-If all worked according to plan, F<myfile.ps> should be typeset using
-extremely thin (half-width) versions of its original fonts.
-
-
-=head2 Producing thin fonts for use in pdfLaTeX
-
-Because B<makethin> can read only F<.dvi> files, not F<.pdf> files, we
-first need to produce a F<.dvi> file:
-
- latex too-long.tex
-
-F<too-long.dvi> is typeset entirely using the Times family of fonts.
-Therefore, we don't need to specify B<-Pcmz>. However, B<pdflatex>
-normally embeds Times, thereby precluding B<makethin>'s ability to
-scale it. (B<makethin> requires a F<.pfb> font file in order to scale
-the corresponding font.) Fortunately,
-F</usr/share/texmf/dvips/config/ar-std-urw-kb.map> already contains
-the proper mapping of TeX names to F<.pfb> files for Times, Courier,
-and Helvetica. We can tell B<makethin> to use that file:
-
- makethin --cleanfirst -v -v too-long.dvi --pdftex --xscale=0.9
- --extramaps=/usr/share/texmf/dvips/config/ar-std-urw-kb.map
-
-In the preceding line, we changed the scaling factor from the default
-of 0.5 to a more reasonable 0.9. Because we had some 0.5-scaled
-F<.tfm> and F<.vf> files left over from the previous example, we
-specified B<--cleanfirst> to delete those old font files. We
-specified B<--pdftex> to make B<makethin> produce a local
-F<pdftex.cfg> file. And we told B<makethin> where to find the extra
-map file needed to force the usage of F<.pfb> files.
-
-All that's left is to run B<pdflatex> to produce a F<.pdf> file:
-
- pdflatex too-long.tex
-
-B<pdflatex> will read the font metric files (F<.tfm> and F<.vf>) and
-F<pdftex.cfg> from the current directory. This will tell it to load
-F<thin.map>, which specifies the scaling factor. The result should be
-a document with each character squeezed to 90% of its original width.

-=head1 RESTRICTIONS
-
-The most serious restriction is that B<makethin> doesn't work on
-Computer Modern Roman 10pt. (F<cmr10>)--the default TeX/LaTeX font.
-The reason, I believe, is that TeX and LaTeX preload that font's
-metrics (F<cmr10.tfm>) and therefore ignore the scaled F<cmr10.tfm> on
-disk. It may be possible to work around this limitation by copying
-F<cmr10.tfm> to a new name and convincing LaTeX to use that name where
-it would otherwise have used F<cmr10.tfm>. However, it's much easier
-merely to use a different font family (e.g., with
-``C<\usepackage{times}>'') for typesetting your document when you know
-you want to run B<makethin>.

+% in your document's preamble. This enables all of the space-saving
+% techniques of which \pkgname{savetrees} is capable and should make

+% violate some imposed formatting restriction (e.g.,~margin width or
+% paragraph indentation); or, even worse, certain space-saving
+% techniques may be incompatible with the document class or another
+% package and produce a \LaTeX\ error. \pkgname{savetrees} therefore
+% provides the ability to selectively enable and disable space-saving
+% techniques via package options. For example,

+% Each of the options that appears in \ref{tbl:st-options} can be
+% set to either |tight| or |normal|. |tight|, the default, enables the
+% space-saving technique while |normal| disables it. For example,
+% specifying |\usepackage[title=normal]{savetrees}| instructs
+% \pkgname{savetrees} not to modify the font size and spacing used to
+% typeset the document's title. If only a few space-saving techniques
+% should be enabled, it may be more convenient to specify |all=normal|
+% followed by a list of options set to |tight| than to specify |normal|
+% typesetting for a large number of options. The arguments passed to
+% |\usepackage| are processed left-to-right.
+%
+% The options in \ref{tbl:st-options} are presented in roughly
+% decreasing order of subtlety. If \pkgname{savetrees}'s default
+% options produce too hideous a result, try incrementally setting the
+% options at the bottom of the table (excluding \pkgname{all}) to
+% |normal|, and see if that improves the document's appearance while
+% still saving space over the non-\pkgname{savetrees} version. That is,
+% start by including |margins=normal| in the optional argument to
+% |\usepackage|. Then add |bibliography=normal|, then
+% |sections=normal|, and so forth, rebuilding the document and examining
+% the result each time. Alternatively, if you need to save just a small
+% amount of space (e.g.,~if your document is just barely over a maximum
+% page length), specify |all=normal| then incrementally add options from
+% the top of the table downwards: |paragraphs=tight|, then
+% |floats=tight|, then |bibnotes=tight|, and so forth.
+% \ref{sec:gallery} presents examples of some of \pkgname{savetrees}'s
+% space-saving features so you can decide for yourself which are worth
+% the price paid in typesetting elegance.
+%
+% Saving space in a document is always a balancing act between document
+% aesthetics and the amount of space that can be saved. If you find
+% that a particular space-saving option makes the document formatting
+% just a little too ugly---or if you're willing to make it even uglier
+% to save even more space---\pkgname{savetrees} provides additional
+% package options that let you adjust the aggressiveness of various
+% space-saving techniques. \vref{tbl:st-refinements} lists and
+% describes these package options. As an example, \LaTeX's normal line
+% height is defined to have a value of~1.0. When \pkgname{savetrees} is
+% loaded with |leading=tight| (the default), \ref{tbl:st-refinements}
+% indicates that the line height is reduced to 90\% of that.
+% Additionally including |leadingfraction=0.95| on the |\usepackage| line
+% increases the line height to 95\% of \LaTeX's default---still a space
+% reduction but possibly a somewhat less overt one.

-% We can do better than merely \emph{selecting} a narrow font, though.

-% In addition to requiring Perl\index{Perl|usage}, \progname{makethin}
-% depends upon two helper programs: \progname{kpsewhich} and
-% \progname{dvitype}. \progname{kpsewhich} searches the \TeX{}

-% \progname{kpsewhich} is a standard part of Kpathsea-based \TeX{}
-% distributions, such as \TeX\ Live, it does not normally function on
-% non-Kpathsea based distributions. \progname{dvitype} outputs a DVI
-% file in a textual format that's easy for \progname{makethin} to
-% process. \progname{makethin} extracts font names from lines like the
-% following:
-%
-% \begin{verbatim}
-% Font 44: cmtt10---loaded at size 655360 DVI units
-% Font 43: cmtt12 scaled 1200---loaded at size 943718 DVI units
-% Font 33: cmss10---loaded at size 655360 DVI units
-% \end{verbatim}
-%
-% Even with \progname{makethin}, creating narrow fonts is somewhat
-% awkward as it requires the installation of various font files and font
-% maps. Fortunately, with newer versions of \pkgname{savetrees}, there
-% is far less need to bother with \progname{makethin}.
-% \pkgname{savetrees}~v1.3 and later use the \pkgname{microtype} package
-% to exploit pdf\TeX's font-expansion features to implicitly generate
-% narrower versions of fonts. The advantage is that this approach is
-% fully automatic; there's no need to install additional font files or
-% font maps. The disadvantages are that (1)~it works only with
-% pdf\TeX\ and (2)~it doesn't compress fonts uniformly but rather allows
-% some variation from line to line based on how overfull or underfull
-% the line would otherwise be. In short, \progname{makethin} should be
-% seen as a last resort, when a significant amount of extra space must
-% be elided from the document.

+% Although \pkgname{savetrees} does not automatically change the

+% This narrowing technique works only with pdf\LaTeX, so that program

+%
+%
+% \section{Gallery of space-saving techniques}
+% \label{sec:gallery}
+%
+% \ref{fig:ex-lists} through \ref{fig:ex-leading}
+% \vpagerefrange{fig:ex-lists}{fig:ex-leading} provide examples of some
+% of the ways that \pkgname{savetrees} saves space when typesetting
+% text. Each figure showcases a single space-saving technique in
+% isolation. The default pararameters are used for each technique.
+% \vref{tbl:st-refinements} documents the package options that can be
+% used to refine these parameters either to save more space or to make
+% the typesetting less offensive.
+%
+% \ref{fig:ex-lists} shows how setting |lists=tight| saves space by
+% reducing the whitespace above, below, and within list environments (in
+% this case, the |itemize| environment). \ref{fig:ex-wordspacing} shows
+% how setting |wordspacing=tight| saves space by typesetting words
+% closer together. \ref{fig:ex-tracking} shows how setting
+% |tracking=tight| saves space by typesetting the characters within a
+% word closer together. \ref{fig:ex-charwidths} shows how setting
+% |charwidths=tight| saves space by narrowing the individual character
+% glyphs without affecting the font's point size (height) or amount of
+% whitespace. Finally, \ref{fig:ex-leading} shows how setting
+% |leading=tight| saves space by removing whitespace between adjacent
+% lines of text. Again, these techniques are shown with their default
+% parameters, which can be adjusted if desired.
+%
+% While \ref{fig:ex-lists} through \ref{fig:ex-leading} each illustrate
+% a single space-saving technique, \vref{fig:ex-multiple} demonstrates
+% that when multiple techniques are used in combination, the benefits
+% are essentially additive.

-% \subsection*{DESCRIPTION}
-% \thinprogidx{makethin} produces thinner versions of PostScript fonts for use
-% with \TeX{}/\LaTeX{} and Dvips. More precisely, it finds all of
-% the \thinextidx{tfm} and \thinextidx{vf} fonts referred to by a
-% \thinextidx{dvi} file, scales the character-width metrics by a given
-% amount, and writes new \thinextidx{tfm} and \thinextidx{vf} files to
-% the current directory. \thinprogidx{makethin} then generates a customized
-% \thinextidx{map} and {\em config\/}^^A
-% \index{config files=\texttt{config} files|usage}
-% file for Dvips and, optionally, a customized
-% \thinfileidx{pdftex.cfg} file for pdf\LaTeX{}.
-%
-% The general procedure for using \thinprogidx{makethin} is as follows:

-%
-% The following are the command-line options that \thinprogidx{makethin} accepts:
-%
-% \begin{description}
-%
-% \item[{\bf -v}, {\bf {\tt --}verbose}]^^A
-% \thinoptidx{v}{verbose}^^A
-% \hfil\\
-% Increase the verbosity of the status output. {\bf {\tt --}verbose} can be
-% specified multiple times on the same command line, with each
-% {\bf {\tt --}verbose} futher increasing the verbosity. (Currently, two
-% {\bf {\tt --}verbose}s have maximal impact.)
-%
-% \item[{\bf -h}, {\bf {\tt --}help}]^^A
-% \thinoptidx{h}{help}^^A
-% \hfil\\
-% Display basic usage information. When combined with {\bf {\tt --}verbose},
-% additionally describes each of the command-line options. When
-% combined with a second {\bf {\tt --}verbose}, {\bf {\tt --}help} outputs the complete
-% \thinprogidx{makethin} manual page.
-%
-% \item[{\bf -x} {\em factor\/}, {\bf {\tt --}xscale}={\em factor\/}]^^A
-% \thinoptidx{x}{xscale}^^A
-% \hfil\\
-% Scale fonts horizontally by a factor of {\em factor\/}. The default,
-% {\tt 0.5}, produces nearly illegible fonts but is useful for verifying
-% that \thinprogidx{makethin} actually worked. Factors of {\tt 0.90}--{\tt 0.99}
-% are more reasonable.
-%
-% \item[{\bf -C}, {\bf {\tt --}cleanfirst}]^^A
-% \thinoptidx{C}{cleanfirst}^^A
-% \hfil\\
-% Delete all files generated by a previous run of \thinprogidx{makethin} before
-% generating new ones.
-%
-% \item[{\bf -c}, {\bf {\tt --}clean}]^^A
-% \thinoptidx{c}{clean}^^A
-% \hfil\\
-% Delete all files generated by a previous run of \thinprogidx{makethin} and then
-% exit.
-%
-% \item[{\bf -P} {\em extension\/}, {\bf {\tt --}config}={\em extension\/}]^^A
-% \thinoptidx{P}{config}^^A

-% \index{config files=\texttt{config} files|usage}
-% (found in Dvips's configuration directory). {\bf {\tt --}config}
-% can be specified multiple times on the same command line.
-% \thinfileidx{config.ps} is processed implicitly. The same {\bf -P}
-% arguments that you would normally pass to \thinprogidx{dvips} to utilize
-% entirely PostScript fonts (e.g., {\bf -Pcmz} and {\bf -Pamz}) should
-% also be passed to \thinprogidx{makethin}.
-%
-% \item[{\bf -p}, {\bf {\tt --}pdftex}]^^A
-% \thinoptidx{p}{pdftex}^^A
-% \hfil\\
-% In addition to producing the files needed by Dvips, also produce a
-% \thinfileidx{pdftex.cfg} file that is usable by pdf\LaTeX{}.
-%
-% \item[{\bf -m} {\em file\/}{\tt [},{\em file\/}{\tt ]}...{\tt ]}, {\bf {\tt --}extramaps}={\em file\/}{\tt [},{\em file\/}{\tt ]}...{\tt ]}]^^A
-% \thinoptidx{m}{extramaps}^^A
-% \hfil\\
-% Additionally process the named Dvips \thinextidx{map} files even if they're
-% not referred to by any of the {\em config.\/}{\em extension\/} files^^A
-% \index{config files=\texttt{config} files|usage}
-% specified with {\bf {\tt --}config}. {\bf {\tt --}extramaps} can be

-% \item[{\bf -k} {\em font\/}{\tt [},{\em font\/}{\tt ]}...{\tt ]}, {\bf {\tt --}skipfonts}={\em font\/}{\tt [},{\em font\/}{\tt ]}...{\tt ]}]^^A
-% \thinoptidx{k}{skipfonts}^^A
-% \hfil\\
-% Don't make thin versions of the named fonts, even if they're listed in
-% the \thinextidx{dvi} file. Fonts are named using the Berry scheme (i.e.,
-% ``{\tt pcrr8a}'' as opposed to ``{\tt COURB}'' or ``{\tt Courier-Bold}'').
-% {\bf {\tt --}skipfonts} can be specified multiple times on the same command
-% line.
-%
-% \item[{\bf -b} {\em string\/}, {\bf {\tt --}basename}={\em string\/}]^^A
-% \thinoptidx{b}{basename}^^A
-% \hfil\\
-% Tell \thinprogidx{makethin} to use {\em string\/} as the base name for the Dvips

-% \thinprogidx{makethin} normally produces files named \thinfileidx{config.thin} and
-% \thinfileidx{thin.map}, but {\bf {\tt --}basename} enables alternate
-% filenames to be used.

+% \section{Implementation of \texttt{savetrees.sty}}
+% \label{sec:savetrees.sty}
%
-% In addition to the options listed above, \thinprogidx{makethin} has a required
-% argument, which is the name of a \thinextidx{dvi} file from which to read font
-% information.
+% This section presents the complete, commented source code for the
+% \pkgname{savetrees} package. Although reading this section---and the
+% subsequent implementation sections---is not necessary for
+% understanding how to use \pkgname{savetrees}, it may be a useful
+% teaching instrument for \LaTeX{} newcomers who want to learn more
+% about fine-tuning document formatting.
%
-% \subsection*{EXAMPLES}
-% The following are some examples of how to use \thinprogidx{makethin}.
+% \begin{macrocode}
+%<*package>
+% \end{macrocode}
%
-% \subsubsection*{A typical case}^^A
+% \subsection{Default values}
%
-% First, we need to produce {\em myfile.dvi\/}, because that contains the
-% font information that \thinprogidx{makethin} will read:
-% \begin{verbatim}
-% latex myfile.tex
-% \end{verbatim}
+% \pkgname{savetrees} attempts to provide a reasonable balance between
+% aesthetics and the amount of space saved in a document. However,
+% \pkgname{savetrees} does enable the document author to adjust a number
+% of parameters to bias \pkgname{savetrees}'s behavior towards either
+% reduced document length or prettier output. This section defines the
+% default values for various package parameters.
%
-% Next, we invoke \thinprogidx{makethin}, telling it to process
-% \thinfileidx{config.cmz} (which, in turn, causes
-% \thinfileidx{psfonts.cmz} to be processed), This tells \thinprogidx{makethin}
-% to use PostScript versions of the Computer Modern fonts instead of
-% bitmapped versions. (\thinprogidx{makethin} can scale only PostScript fonts.)
-% We also specify maximal verbosity:
-% \begin{verbatim}
-% makethin -Pcmz --verbose --verbose myfile.dvi
-% \end{verbatim}
-%
-% The preceding line reads \thinfileidx{config.ps},
-% \thinfileidx{config.cmz}, various map files, such as
-% \thinfileidx{psfonts.map} and \thinfileidx{psfonts.cmz}, and all of
-% the \thinextidx{tfm} and \thinextidx{vf} files mentioned in {\em
-% myfile.dvi\/}. It then writes \thinfileidx{config.thin},
-% \thinfileidx{thin.map}, and modified versions of all of the
-% \thinextidx{tfm} and \thinextidx{vf} files to the current directory.
-%
-% We now need to re-run \thinprogidx{latex}, so it can produce a new {\em myfile.dvi\/}
-% using the thinner metrics listed in the current directory's \thinextidx{tfm}
-% and \thinextidx{vf} files:
-% \begin{verbatim}
-% latex myfile.tex
-% \end{verbatim}
-%
-% Finally, we produce a PostScript file using the newly generated using
-% \thinfileidx{config.thin} and \thinfileidx{thin.map} files:
-% \begin{verbatim}
-% dvips -Pthin myfile.dvi -o myfile.ps
-% \end{verbatim}
+% \begin{macro}{\st@margin@width}
+% When |margins=tight|, |\st@margin@width| specifies how wide the page
+% margins should be. The default, 1.5\,cm, is extremely small, but it
+% can sure save a lot of space on the page.
+% \begin{macrocode}
+\newcommand*{\st@margin@width}{1.5cm}
+% \end{macrocode}
+% \end{macro}
%
-% If all worked according to plan, {\em myfile.ps\/} should be typeset using
-% extremely thin (half-width) versions of its original fonts.
+% \begin{macro}{\st@parindent}
+% The standard \LaTeX\ classes (|article|, |report|, and |book|) define
+% paragraph indentation as follows. If |twocolumn| is in effect,
+% |\parindent| is set to 1\,em. Otherwise, if the base font size is
+% 10\,pt., |\parindent| is set to 15\,pt.; if the base font size is
+% 11\,pt., |\parindent| is set to 17\,pt.; and if the base font size is
+% 12\,pt., |\parindent| is set to 1.5\,em. When |indent=tight|,
+% \pkgname{savetrees} uses a default of 1\,em---approximately a third of
+% the no-\pkgname{savetrees} value---regardless of font size.
+% \begin{macrocode}
+\newcommand*{\st@parindent}{1em}
+% \end{macrocode}
+% \end{macro}
%
-% \subsubsection*{Producing thin fonts for use in pdf\LaTeX{}}^^A
-% \index{pdfLaTeX=pdf\LaTeX{}|(usage}
+% \begin{macro}{\st@baselinestretch}
+% Depending on font size, the standard \LaTeX\ classes (|article|,
+% |report|, and |book|) use 2--2.6\,pt.\ lead (inter-line spacing), or
+% approximately~20\% of font size. Specifically, they typeset body text
+% at 10/12, 11/13.6, or 12/14.5. When |leading=tight|,
+% \pkgname{savetrees} reduces the line spacing to 90\% of normal or an
+% average of about~1.3\,pt.\ less lead than \LaTeX's defaults: 10/10.8,
+% 11/12.24, or 12/13.05. 90\% gives very good compression but still
+% prevents descenders from running into successive ascenders.
+% \begin{macrocode}
+\newcommand*{\st@baselinestretch}{0.9}
+% \end{macrocode}
+% \end{macro}
%
-% Because \thinprogidx{makethin} can read only \thinextidx{dvi} files, not
-% \thinextidx{pdf} files, we first need to produce a \thinextidx{dvi}
-% file:
-% \begin{verbatim}
-% latex too-long.tex
-% \end{verbatim}
+% \begin{macro}{\st@char@shrink}
+% When |charwidths=tight|, \pkgname{savetrees} disables font expansion
+% but enables font compaction. The default contraction of 5\% (50/1000)
+% of normal character widths is largely undetectable to the casual
+% observer but can save a great deal of space over the course of a long
+% document.
+% \begin{macrocode}
+\newcommand*{\st@char@shrink}{50}
+% \end{macrocode}
+% \end{macro}
%
-% {\em too-long.dvi\/} is typeset entirely using the Times family of
-% fonts. Therefore, we don't need to specify {\bf -Pcmz}. However,
-% {\bf pdflatex} normally embeds Times, thereby precluding {\bf
-% makethin}'s ability to scale it. (\thinprogidx{makethin} requires a {\em
-% .pfb\/} font file in order to scale the corresponding font.)
-% Fortunately, {\em /usr/share/texmf/dvips/config/ar-std-urw-kb.map\/}^^A
-% \index{ar-std-urw-kb.map=\texttt{ar-std-urw-kb.map}|usage}
-% already contains the proper mapping of \TeX{} names to \thinextidx{pfb}
-% files for Times, Courier, and Helvetica. We can tell \thinprogidx{makethin}
-% to use that file:
-% \begin{verbatim}
-% makethin --cleanfirst -v -v too-long.dvi --pdftex --xscale=0.9
-% --extramaps=/usr/share/texmf/dvips/config/ar-std-urw-kb.map
-% \end{verbatim}
+% \begin{macro}{\st@cspace@shrink}
+% \pkgname{savetrees} reduces tracking (inter-character spacing)
+% when |tracking=tight|. By default, tracking is set to -2.5\%
+% (-25/1000) of an em~width. When decreased much more than that,
+% characters begin to overlap and become hard to read.
+% \begin{macrocode}
+\newcommand*{\st@cspace@shrink}{-25}
+% \end{macrocode}
+% \end{macro}
%
-% In the preceding line, we changed the scaling factor from the default
-% of 0.5 to a more reasonable 0.9. Because we had some 0.5-scaled
-% \thinextidx{tfm} and \thinextidx{vf} files left over from the previous
-% example, we specified {\bf {\tt --}cleanfirst} to delete those old
-% font files. We specified {\bf {\tt --}pdftex} to make \thinprogidx{makethin}
-% produce a local \thinfileidx{pdftex.cfg} file. And we told {\bf
-% makethin} where to find the extra map file needed to force the usage
-% of \thinextidx{pfb} files.
-%
-% All that's left is to run {\bf pdflatex} to produce a \thinextidx{pdf}
-% file:
-% \begin{verbatim}
-% pdflatex too-long.tex
-% \end{verbatim}
+% \begin{macro}{\st@wspace@factor}
+% \pkgname{savetrees} reduces inter-word spacing when
+% |wordspacing=tight|. By default, inter-word spacing is set to 80\% of
+% normal. If decreased much beyond that, words start to run together
+% and become hard to read.
+% \begin{macrocode}
+\newcommand*{\st@wspace@factor}{0.8}
+% \end{macrocode}
+% \end{macro}
%
-% {\bf pdflatex} will read the font metric files (\thinextidx{tfm} and
-% \thinextidx{vf}) and \thinfileidx{pdftex.cfg} from the current
-% directory. This will tell it to load \thinfileidx{thin.map}, which
-% specifies the scaling factor. The result should be a document with

-% therefore ignore the scaled \thinfileidx{cmr10.tfm} on disk. It may
-% be possible to work around this limitation by copying
-% \thinfileidx{cmr10.tfm} to a new name and convincing \LaTeX{} to use that
-% name where it would otherwise have used \thinfileidx{cmr10.tfm}.
-% However, it's much easier merely to use a different font family (e.g.,
-% with ``{\tt \char`\\usepackage\{times\}}'') for typesetting your
-% document when you know you want to run \thinprogidx{makethin}.

+% gives a document author the ability to enable or disable options as
+% desired. To move authors to the new set of parameters, we define all
+% of the old options as error-generating calls.

+% parameters. |\fontdimen2| represents the base inter-word spacing.
+% (|\fontdimen3| and |\fontdimen4| represent, respectively, the amount
+% by which inter-word spacing can stretch or shrink; \pkgname{savetrees}
+% does not currently alter those.) Here, we hook into \LaTeXe's
+% font-loading mechanism. Whenever a new font is loaded, we specify
+% that the inter-word spacing for that font should be reduced.

-% \end{macrocode}

-% \begin{enumerate}
-% \item Read all of the TFM and VF fonts named in the given DVI file.

-% \item For each font, perform the following operations:
-%
-% \begin{enumerate}
-% \item If the font is a virtual font (|.vf|), then add all of the
-% VF and TFM fonts it names to the end of the font ``to-do'' list.
-%
-% \item If the font contains \TeX{} font metrics (|.tfm|), then
-% convert the font to an ASCII property list (|.pl|), replace each
-% ``|(CHARWD|~|R|~\meta{width}|)|'' expression with
-% ``|(CHARWD|~|R|~\meta{width}$\times$\meta{x-scale}|)|'', and
-% convert the result back to a |.tfm| file in the current directory.
-% \end{enumerate}
-%
-% \item Acquire a list of font-map files from |config.ps| and any other
-% Dvips configuration specified on the command line.
-%
-% \item Create a new font-map file, containing one line for each font
-% named in the given DVI file, but modified to specify
-% ``|"|\meta{x-scale} |ExtendFont"|'' on each line.
-%
-% \item Create a new Dvips configuration file that points to the new

-
-
-
-=head1 DESCRIPTION
-
-B<makethin> produces thinner versions of PostScript fonts for use with
-TeX/LaTeX and Dvips. More precisely, it finds all of the F<.tfm>
-and F<.vf> fonts referred to by a F<.dvi> file, scales the
-character-width metrics by a given amount, and writes new F<.tfm> and
-F<.vf> files to the current directory. B<makethin> then generates a
-customized F<.map> and F<config> file for Dvips and, optionally, a
-customized F<pdftex.cfg> file for pdfLaTeX.
-
-The general procedure for using B<makethin> is as follows:
-
-=over 4
-
-=item 1.
-
-Run B<latex> on your F<.tex> source file to produce a F<.dvi> file.
-
-=item 2.
-
-Run B<makethin> on the F<.dvi> file to create new F<.tfm>, F<.vf>,
-F<.map>, and F<config> files.
-
-=item 3.
-
-Re-run B<latex> on your F<.tex> source file to typeset it with the new
-fonts.
-
-=item 4.
-
-Run B<dvips> on the F<.dvi> file, specifying the newly generated
-F<.map> and F<config> files, to produce a F<.ps> file.
-
-=back
-
-
-=head1 OPTIONS
-
-The following are the command-line options that B<makethin> accepts:
-
-=over 4
-
-=item B<-v>, B<--verbose>
-
-Increase the verbosity of the status output. B<--verbose> can be
-specified multiple times on the same command line, with each
-B<--verbose> futher increasing the verbosity. (Currently, two
-B<--verbose>s have maximal impact.)
-
-=item B<-h>, B<--help>
-
-Display basic usage information. When combined with B<--verbose>,
-additionally describes each of the command-line options. When
-combined with a second B<--verbose>, B<--help> outputs the complete
-B<makethin> manual page.
-
-=item B<-x> I<factor>, B<--xscale>=I<factor>
-
-Scale fonts horizontally by a factor of I<factor>. The default,
-C<0.5>, produces nearly illegible fonts but is useful for verifying
-that B<makethin> actually worked. Factors of C<0.90>-C<0.99> are more
-reasonable.
-
-=item B<-C>, B<--cleanfirst>
-
-Delete all files generated by a previous run of B<makethin> before
-generating new ones.
-
-=item B<-c>, B<--clean>
-
-Delete all files generated by a previous run of B<makethin> and then
-exit.
-
-=item B<-P> I<extension>, B<--config>=I<extension>
-
-Process all of the F<.map> files named in F<config.>I<extension>
-(found in Dvips's configuration directory). B<--config> can be
-specified multiple times on the same command line. F<config.ps> is
-processed implicitly. The same B<-P> arguments that you would
-normally pass to B<dvips> to utilize entirely PostScript fonts (e.g.,
-B<-Pcmz> and B<-Pamz>) should also be passed to B<makethin>.
-
-=item B<-p>, B<--pdftex>
-
-In addition to producing the files needed by Dvips, also produce a
-F<pdftex.cfg> file that is usable by pdfLaTeX.
-
-=item B<-m> I<file>[,I<file>]...], B<--extramaps>=I<file>[,I<file>]...]
-

-

-
-=item B<-b> I<string>, B<--basename>=I<string>
-
-Tell B<makethin> to use I<string> as the base name for the Dvips
-configuration files it generates. The default is ``C<thin>'', so
-B<makethin> normally produces files named F<config.thin> and
-F<thin.map>, but B<--basename> enables alternate filenames to be used.
-

-
-Make thin versions of the named fonts, even if they're not listed in

-
-Create a Unix manual page for B<makethin> in the standard, *roff

-
-=item B<--man-ps>=I<PostScript file>
-
-Create a Unix manual page for B<makethin> in PostScript format instead
-of *roff format.
-
-=back
-
-In addition to the options listed above, B<makethin> has a required
-argument, which is the name of a F<.dvi> file from which to read font
-information.
-
-
-=head1 EXAMPLES
-
-The following are some examples of how to use B<makethin>.
-
-=head2 A typical case
-
-First, we need to produce F<myfile.dvi>, because that contains the
-font information that B<makethin> will read:
-
- latex myfile.tex
-
-Next, we invoke B<makethin>, telling it to process F<config.cmz>
-(which, in turn, causes F<psfonts.cmz> to be processed), This tells
-B<makethin> to use PostScript versions of the Computer Modern fonts
-instead of bitmapped versions. (B<makethin> can scale only PostScript
-fonts.) We also specify maximal verbosity:
-
- makethin -Pcmz --verbose --verbose myfile.dvi
-
-The preceding line reads F<config.ps>, F<config.cmz>, various map
-files, such as F<psfonts.map> and F<psfonts.cmz>, and all of the
-F<.tfm> and F<.vf> files mentioned in F<myfile.dvi>. It then writes
-F<config.thin>, F<thin.map>, and modified versions of all of the
-F<.tfm> and F<.vf> files to the current directory.
-
-We now need to re-run B<latex>, so it can produce a new F<myfile.dvi>
-using the thinner metrics listed in the current directory's F<.tfm>
-and F<.vf> files:
-
- latex myfile.tex
-
-Finally, we produce a PostScript file using the newly generated using
-F<config.thin> and F<thin.map> files:
-
- dvips -Pthin myfile.dvi -o myfile.ps
-
-If all worked according to plan, F<myfile.ps> should be typeset using
-extremely thin (half-width) versions of its original fonts.
-
-
-=head2 Producing thin fonts for use in pdfLaTeX
-
-Because B<makethin> can read only F<.dvi> files, not F<.pdf> files, we
-first need to produce a F<.dvi> file:
-
- latex too-long.tex
-
-F<too-long.dvi> is typeset entirely using the Times family of fonts.
-Therefore, we don't need to specify B<-Pcmz>. However, B<pdflatex>
-normally embeds Times, thereby precluding B<makethin>'s ability to
-scale it. (B<makethin> requires a F<.pfb> font file in order to scale
-the corresponding font.) Fortunately,
-F</usr/share/texmf/dvips/config/ar-std-urw-kb.map> already contains
-the proper mapping of TeX names to F<.pfb> files for Times, Courier,
-and Helvetica. We can tell B<makethin> to use that file:
-
- makethin --cleanfirst -v -v too-long.dvi --pdftex --xscale=0.9
- --extramaps=/usr/share/texmf/dvips/config/ar-std-urw-kb.map
-
-In the preceding line, we changed the scaling factor from the default
-of 0.5 to a more reasonable 0.9. Because we had some 0.5-scaled
-F<.tfm> and F<.vf> files left over from the previous example, we
-specified B<--cleanfirst> to delete those old font files. We
-specified B<--pdftex> to make B<makethin> produce a local
-F<pdftex.cfg> file. And we told B<makethin> where to find the extra
-map file needed to force the usage of F<.pfb> files.
-
-All that's left is to run B<pdflatex> to produce a F<.pdf> file:
-
- pdflatex too-long.tex
-
-B<pdflatex> will read the font metric files (F<.tfm> and F<.vf>) and
-F<pdftex.cfg> from the current directory. This will tell it to load
-F<thin.map>, which specifies the scaling factor. The result should be
-a document with each character squeezed to 90% of its original width.

-
-=item B<groff>
-
-used by B<--man-ps> to produce a PostScript version of the Unix manual
-page for B<makethin>
-
-=back
-
-
-=head1 RESTRICTIONS
-
-The most serious restriction is that B<makethin> doesn't work on
-Computer Modern Roman 10pt. (F<cmr10>)--the default TeX/LaTeX font.
-The reason, I believe, is that TeX and LaTeX preload that font's
-metrics (F<cmr10.tfm>) and therefore ignore the scaled F<cmr10.tfm> on
-disk. It may be possible to work around this limitation by copying
-F<cmr10.tfm> to a new name and convincing LaTeX to use that name where
-it would otherwise have used F<cmr10.tfm>. However, it's much easier
-merely to use a different font family (e.g., with
-``C<\usepackage{times}>'') for typesetting your document when you know
-you want to run B<makethin>.
