+% Version
+% -------
+% This is FunnelWeb TeX Macro Library Version 1.0.

+
+% Copyright
+% ---------
+% This set of FunnelWeb TeX definitions was written by Ross Williams and was
+% originally Copyright (C) 1992 Ross N. Williams.  However, I, Ross Williams,
+% hereby forego any claim to Copyright in this set of FunnelWeb TeX definitions
+% and hereby authorize that the set of TeX definitions pass into the public
+% domain. -- Ross N. Williams, 3:41pm 07-May-1992, Adelaide, Australia.

+% Changes:
+%    07-May-1992  RNW  Prepared this work for public domain release.
+%
+
+
+% General Comments
+% ----------------
+% This set of TeX definitions exists for two reasons:
+%
+%    1. To shorten and neaten the FunnelWeb TeX output.
+%    2. To allow users to fiddle with the output format in their input files
+%       (by inserting redefining "\def"s) without having to resort to
+%       modifying the FunnelWeb code.
+%
+% The user is warned that these definitions may be changed from time to time
+% (but probably not much). The user should not be too sneaky. In particular,
+% users wishing to redefine some of these macros should do so in an explicitly
+% defined section at the top of their input file. This will mean that in the
+% event of problems, that section can simply be deleted or commented out to
+% allow the document to at least be typeset in the default format. Users should
+% limit themselves to redefining these macros in such a section and should
+% refrain from using the macros throughout their documents.
+
+
+% Environment Parameters
+% ----------------------
+% \tolerance tells TeX how tolerant it should be about making bad line and
+% page breaks. Here we set it to it's maximum, as
+%   1) Computer programs are likely to cause lots of bad breaks.
+%   2) In most cases the user would probably rather get the TeX file through
+%      TeX without any errors than fiddle with spacings for perfection.
+\tolerance=10000
+
+% I don't like indentation as it makes the page look more busy. Instead,
+% paragraphs are separated by a little space (see next).
+\parindent=0pt
+
+% In many cases, users will produce documents with long runs of paragraphs.
+% In order to space out these paragraphs, it is convenient to maintain a
+% prevailing non-zero \parskip (end-of-paragaph skip). The only trouble is
+% that the skip becomes a problem in macro definitions which require no skip
+% and so we have to turn the skip on and off. The following two macros
+% simplify this process.
+\def\fwparskipon{\parskip=\medskipamount}
+\def\fwparskipoff{\parskip=0pt}
+\fwparskipon
+
+% Setting raggedbottom allows TeX to leave a bit of space at the bottom of the
+% page in order to better vertically align the rest of the page (e.g. skips
+% won't stretch as much). It also means that headings are less likely to be
+% isolated at the bottom of the page without any following text.
+\raggedbottom
+
+
+% Fonts
+% -----
+% Most of the typeset output is set in 10pt roman and 10pt tt font.
+% The major extra font needs spring from titles and headings.
+% For portability's sake we use only the following fonts:
+%    cmr10
+%    cmbx10
+%    cmtt10
+% and some enlargements of them. These fonts are all "standard" fonts
+% in Plain TeX. See The TeXbook p.350.
+\font\fwfontnote=cmr7
+
+\font\fwfontnorm=cmr10
+\font\fwfontnorma=cmr10 scaled \magstep1
+\font\fwfontnormb=cmr10 scaled \magstep2
+
+\font\fwfontbold=cmbx10
+\font\fwfontbolda=cmbx10 scaled \magstep1
+\font\fwfontboldb=cmbx10 scaled \magstep2
+\font\fwfontboldc=cmbx10 scaled \magstep3
+\font\fwfontboldd=cmbx10 scaled \magstep4
+
+
+% Macros for Stylistic Details
+% ----------------------------
+% This section contains all the fiddly little macros for setting the details
+% of each macro definition.
+
+% Macro definitions are sandwiched by calls to these macros which can be used
+% to sort out the spacing before and after the macro definition.
+\def\fwbeginmacro{\fwparskipoff\bigskip}
+\def\fwendmacro{\fwparskipon\par}
+
+% These macros deal with the macro name and definition line.
+\def\fwmacroname#1#2{{\sl #1\/}$\lbrack$#2$\rbrack$}
+\def\fwfilename#1#2{{\bf #1}$\lbrack$#2$\rbrack$}
+\def\fwzero#1{{\bf Z}}
+\def\fwmany#1{{\bf M}}
+\def\fwequals{ $\equiv$}
+\def\fwplusequals{ $+\equiv$}
+
+% Now for the actual body of the definition. It looks nice to have the tt
+% code indented a little. Again, we use macros instead of writing direct TeX,
+% so as to allow the user to fiddle this stuff to taste without having to
+% modify the FunnelWeb C code.
+\def\fwodef{\parindent=15pt\vskip0pt$\lbrace$\parindent=20pt}
+\def\fwcdef{$\rbrace$\vskip0pt\parindent=0pt}
+\def\fwoquote{`}
+\def\fwcquote{'}
+\def\fwoparen{$($}
+\def\fwcomma{$,$}
+\def\fwcparen{$)$}
+\def\fwparam#1{$\diamond #1$}
+\def\fwparams#1{$(\diamond #1)$}
+
+% These macros deal with the notes that are appended at the end of each
+% macro definition. Note that even though \fwisafile,\fwusedin, and \fwseealso
+% have the same definition, they are given different names so as to allow the
+% user to redefine these macros to typeset each kind of information differently
+% if desired.
+\def\fwbeginmacronotes{\begingroup\baselineskip=9pt\smallskip}
+\def\fwnote#1{{\fwfontnote #1}\par}
+\def\fwisafile#1{\fwnote{#1}}
+\def\fwusedin#1{\fwnote{#1}}
+\def\fwseealso#1{\fwnote{#1}}
+\def\fwendmacronotes{\endgroup}
+
+
+% Macros to Typeset Program Code Verbatim
+% ---------------------------------------
+% This is by far the hairiest and most difficult part of the typesetting task
+% because we have to turn off most of TeX's natural instincts in order to
+% typeset the program text exactly as it appears in the input file.
+% Two macros are defined to pull this off: \fwbtx and \fwverbatimgobble.
+% Their code was inspired by the following sections of "The TeXbook":
+%    Appendix D: Dirty Tricks, 3.Verbatim listing, p.380-382.
+%    Appendix E: Example Formats, p.421.
+% The \fwbtx[ (for "FunnelWeb Begin TeXt") macro does most of the hard work.
+% The liberal use of "%" is because I don't understand TeX well enough to
+% understand when an end of line will cause trouble, and I am playing it safe.
+
+% Before defining the main \fwbtx macro, we have to stash away some definitions
+% in the hidden part of TeX's environment. Let's hope that these "hidden"
+% definitions don't affect anything except what is desired to be affected.
+
+% The tt font in which we wish to set the text has two Latin lurking ligatures!
+% These are ?` and !`. To disable them, we define the left quote when ACTIVE
+% to be defined in such a way as to prevent ligatures. The main TeX text will
+% normally not be exposed to this definition because normally the leftquote
+% character is not active. The \fwbtx macro temporarily makes the left quote
+% character active thus activating the deactivation of left quote ligatures.
+% See The TeXbook p.381.
+{\catcode`\`=\active \gdef`{\relax\lq}}
+
+% TeX is fairly carefree about spaces and so we have to make it more serious.
+% To do so we pull the same trick as above, setting up a definition for active
+% space, but only making space active during the span of the verbatim text.
+% In Plain TeX the active space is defined to be simply a space, but here we
+% define it to be a control space. This ensures that the space cannot
+% be gobbled up by one of TeX's mysterious mechanisms when activated.
+% See The TeXbook, p.381 and p.352.
+{\obeyspaces\global\let =\ }
+
+% Here is the main \fwbtx verbatim text macro.
+% Note: The order in which all these pieces of business have to be done is
+% still a partial mystery to me. Don't fiddle with this stuff unless you
+% think you know what you are doing.
+\def\fwbtx[{%
+%
+% The funnies involved in getting verbatim output are safely housed inside
+% this \begingroup, and the \endgroup in \fwverbatimgobble. Groups are used
+% instead of curly braces because we have to be able to signal the end of
+% this macro with a curly brace.
+\begingroup%
+%
+% \pars at the end of empty lines in the verbatim text won't come out normally
+% because TeX is in vertical mode and they get gobbled up. To prevent this,
+% we force \par to exit vertical mode first. See The TeXbook p.381.
+\def\par{\leavevmode\endgraf}%
+%
+% Activate the leftquote character so as to avoid ligatures (see above).
+\catcode`\`=\active%
+%
+% The \obeylines macro simply defines end of line (^M) to be \par. This ensures
+% that TeX will treat each verbatim line as a new paragraph.
+\obeylines%
+%
+% To get verbatim output, we have to desex all the special characters. This
+% is explained in detail in The TeXbook p.380.
+\def\do##1{\catcode`##1=12 }\dospecials%
+%
+% Activate the space character so as to make TeX treat blanks seriously.
+% This activation invokes an eralier definition (see above).
+\obeyspaces
+%
+% Interparagraph skips do not help the cause.
+% Note: We have to preserve the indentation though, as the code is actually
+% indented in the final output. See \fwodef in an earlier section.
+\parskip=0pt%
+%
+% We typeset the verbatim text in tt font (courier on the Macintosh) for a
+% number of reasons:
+%    - tt font has the same horizontal spacing for each character.
+%    - tt font covers the ASCII character set.
+%    - tt font doesn't have many surprises (e.g. ligatures).
+%    - tt font looks much what you might see on a computer terminal screen.
+\tt%
+%
+% Having set up an environment for verbatim, we are ready to use it.
+% By invoking \fwverbatimgobble, this \fwbtx macro gobbles up text verbatim (as
+% part of the parameter of \fwverbatimgobble) until it sees the termination
+% string "]fwetx=" (the "=" was thrown in to add obscurity as this sequence
+% must never occur in the verbatim text).
+\fwverbatimgobble}
+
+% The \fwverbatimgobble macro exists to allow \fwbtx to bracket verbatim text.
+\def\fwverbatimgobble#1]fwetx={#1\endgroup}
+
+
+% Table of Contents
+% -----------------
+% The five levels of table of contents that FunnelWeb supports are identified
+% by the five letters [A..E]. These are used throughout the following macros.
+
+% The following macros are utilities to the TOC macros to follow.
+\def\fwrule{\medskip\hrule\medskip}
+\def\fwqh{\hskip1.5em\relax}
+\def\fwbeforesec{\penalty-200\bigskip\medskip\par}
+
+% The following macros are used to typeset the table of contents.
+\def\fwtocstart#1{\fwrule\leftline{\fwfontbolda Table of Contents}\fwrule}
+\def\fwtoca#1#2{\leftline{{\bf #1 #2}}}
+\def\fwtocb#1#2{\leftline{\fwqh #1 #2}}
+\def\fwtocc#1#2{\leftline{\fwqh\fwqh #1 #2}}
+\def\fwtocd#1#2{\leftline{\fwqh\fwqh\fwqh #1 #2}}
+\def\fwtoce#1#2{\leftline{\fwqh\fwqh\fwqh\fwqh #1 #2}}
+\def\fwtocfinish#1{\fwrule}
+
+% The following "library" macros define five different strengths of headings
+% which can be used later in the section macros.
+\def\fwliba#1#2{\vfill\eject{\fwfontboldc #1 #2}\penalty200\smallskip}
+\def\fwlibb#1#2{\fwbeforesec{\fwfontboldb #1 #2}\penalty200\smallskip}
+\def\fwlibc#1#2{\fwbeforesec{\fwfontnormb #1 #2}\penalty200\smallskip}
+\def\fwlibd#1#2{\fwbeforesec{\bf          #1 #2}\penalty200}
+\def\fwlibe#1#2{\fwbeforesec{\bf          #1 #2}}
+
+% Here are the macros that actually typeset the section headings throughout
+% the document. The fwlib system has been employed so as to easily allow the
+% user to redefine the strengths of headings to taste. For example, the
+% user could insert in the input document a similar set of definitions to these
+% but with the b..e headings set to \fwlibc. This would tone down the output.
+\def\fwseca#1#2{\fwliba{#1}{#2}}
+\def\fwsecb#1#2{\fwlibb{#1}{#2}}
+\def\fwsecc#1#2{\fwlibc{#1}{#2}}
+\def\fwsecd#1#2{\fwlibd{#1}{#2}}
+\def\fwsece#1#2{\fwlibe{#1}{#2}}
+
+
+% Support for Explicit Typesetting
+% --------------------------------
+% FunnelWeb supports pragmas and other constructs that allow
+% typesetter-independent typesetting commands to be given. The
+% following macros support these features.
+
+% The in-text literal @{sloth@} and emphasise @[walrus@] features.
+\def\fwlit#1{{\tt #1}}
+\def\fwemp#1{{\it #1}}
+
+% The "@p new_page" pragma.
+\def\fwnewpage{\vfill\eject}
+
+% The "@p vskip Nmm" pragma.
+\def\fwvskip#1{\null\vskip #1mm}
+
+% The "@p title <font> <align> <text>" pragma.
+\def\fwfontnormal#1{{\fwfontnorm {#1}}}
+\def\fwfonttitle#1{{\fwfontboldd {#1}}}
+\def\fwfontsmalltitle#1{{\fwfontboldb {#1}}}
+\def\fwleftline#1{\leftline{#1}}
+\def\fwcenterline#1{\centerline{#1}}
+\def\fwrightline#1{\rightline{#1}}
+
+
+% Support for Old FunnelWeb
+% -------------------------
+% The following macros were used extensively in the first version of
+% FunnelWeb and are retained so that these older input files will still
+% typeset cleanly.
+\def\p#1{{\tt #1}}  % P for Program text.
+\def\flagpage#1#2{
+   \null
+   \vfill
+   \centerline{\fwfontboldd #1}
+   \vskip 1cm
+   \centerline{\fwfontboldd #2}
+   \vfill
+   \null
+   \vfill
+}
