% \division{Intro, usage}
%
% This package redefines the |\verb| command and the \env{verbatim}
% environment so that the verbatim text can break into lines, with |%|
% (or another character chosen to be the comment char) as
% a~`hyphen'. Moreover, it allows the user to define \hisher\ own
% \env{verbatim}-like environments provided their contents would be not
% \emph{horribly} long (as long as a macro's argument may be at most).
%
% This package also allows the user to declare a chosen char(s) as
% a `short verb' e.g., to write \verb+|\a\verbatim\example|+ instead of
% \verb+\verb|\a\verbatim\example|+.
% \dekmedskip
%
% The \pk{gmverb} package redefines the |\verb| command and the
% \env{verbatim} environment in such a~way that | |, |{| and |\| are
% breakable, the first with no `hyphen' and the other two with the
% comment char as a~hyphen. I.e., |{|\<subsequent text>|}| breaks into
% |{%|\par \<subsequent text>|}| ^^A]  bal. braces for Emacs
% and \<text>|\mymacro| breaks into \<text>|%|\par
% |\mymacro|.
%
% (If you don't like line breaking at backslash, there's the
% \TextUsage\nobreakbslash\ declaration (observing the common scoping
% rules, hence \acro{OCSR}) and an analogous
% declaration for the left brace: \TextUsage\nobreaklbrace.)
% \dekmedskip
%
% The default `hyphen' is |%| since it's the default comment char. If
% you wish another char to appear at the line break, use the
% \TextUsage\VerbHyphen\ declaration that takes |\|\<char> as the only
% argument. This declaration is always global.
%
% \stanza
% Another difference is the \TextUsage\verbeolOK\ declaration
% (\acro{OCSR}). Within its scope, |\verb| allows an
% end of a~line in its argument and typesets it just as a~space.
%
% As in the standard version(s), the plain |\verb| typesets the spaces
% blank and |\verb*| makes them visible.
%
% Moreover, \pk{gmverb} provides the \TextUsage\MakeShortVerb\ macro
% that takes a~one-char control sequence as the only argument and
% turns the char used into a~short verbatim delimiter, e.g., after
% \verb+\MakeShortVerb*\|+ (as you guess, the declaration has its
% starred version, which is for visible spaces, and the non-starred for
% the spaces blank) you may type \verb+|\mymacro|+ to get |\mymacro|
% instead of typing |\verb+\mymacro+|. Because the char used in this
% example is my favourite and used just this way by DEK in the
% \TeXbook's format, \pk{gmverb} provides a~macro \TextUsage\dekclubs\
% as a~shorthand for \verb+\MakeShortVerb(*)\|+.
%
% Be careful because such active chars may interfere with other
% things, e.g.\ \verb+|+ with the \pk{tikz} package. If this
% happens, you can declare  \TextUsage\DeleteShortVerb\verb+\|+
% and the previous meaning of the char used shall be restored.
%
% One more difference between \pk{gmverb} and \pk{shortvrb} is that
% the chars |\active|ated  by |\MakeShortVerb| in the math mode behave
% as if they were `other', so you may type e.g., \verb+$2|0$+ to get
% $2|0$ and |+| |\active|ated this way is in the math mode typeset properly
% etc.
%
% However, if you don't like such a~conditional behaviour, you may
% specify some |$$$$|'s (any nonempty seQuence) mixed with star(s) if
% you wish as an optional argument to keep the short-verbatim char
% behave as short-verbatim also in math mode.
%
% For compatibility with \pk{gmdoc} and for convenience there is a
% shorthand for that provided, \TextUsage\OldMakeShortVerb.%
%
%
% There's one more declaration provided by \pk{gmverb}:
% \TextUsage\dekclubs, which is a~shorthand for
% \verb+\MakeShortVerb\|+, \TextUsage*{\dekclubs*}\ for
% \verb+\MakeShortVerb*\|+ and \TextUsage\olddekclubs\ for
% \verb+\OldMakeShortVerb\|+.
%
% There's one more declaration, \TextUsage\edverbs\ that makes
% \cs{[} %^^A]
% checks if the next token is an active char and opens an |\hbox| if
% so. That is done
% so that you can write (in  |\edverbs|' and |\dekclubs|' scope)
%\[\verb+\[|<verbatim stuff>|\]+\]
% instead of
%\[\verb+\[\hbox{|<verbatim stuff>|}\]+\]
% to get a~displayed shortverb.
%
% Both versions of |\dekclubs| \acro{OCSR}.
%
% The \env{verbatim} environment inserts |\topsep| before and after
% itself, just as in standard version (as if it was a~\env{list}).
%
% In August 2008 Will Robertson suggested grey visible spaces for
% \pk{gmdoc}. I~added a~respective option to \pk{gmdoc} but I~find
% them so nice that I~want to make them available for all verbatim
% environments so I~bring here the declaration
% \TextUsage\VisSpacesGrey. It redefines only the visible spaces so
% affects \cs{verb*} and \env{verbatim*} and not the unstarred
% versions. The colour of the visible spaces is named
% \TextUsage*{visspacesgrey} and you can redefine it \pk{xcolor} way.
%
% \stanza
% We also provide the \TextUsage\verbatimspecials\ declaration that
% takes six arguments:
% \begin{enumargs}
% \dc * m  a~char for verbatim escape char (for catcode 0), has to be
% unbraced\qfootnote{To be precise, the arguments cannot be wrapped in
% curly braces because those are recatcoded to
% ‘other’. But if you make some other pair of chars  category 1 and 2
% that are not on the \cmd\dospecials\ list, then you can wrap the
% arguments in those chars. But what for?},
% \dc * m a~char for group starter (for catcode 1), has to be
% unbraced,
% \dc * m a~char for group ender (for catcode 2), has to be
% unbraced,
% \opt (optional) a~char for verbatim math shift (for catcode 3); it has
% to be in square brackets if present. If
% absent, nothing is set for the verbatim math shift,
% \opt (optional) a~char for the shorthand for |\metachar|; it has to be
% in square brackets if present. If provided, e.g., |⁄››| as I suggest
% in |\GMverbatimspecials|, then it itself becomes an active char
% let-equal to |\meta|, and a \CS made of it, |⁄›⁄›| in this example,
% becomes |\string|.
% \dc b optional in curly braces, additional stuff (commands) to be
% executed in a~verbatim.
% \end{enumargs}
% All the specials defined this way, except the meta char, if preceded
% with the escape char, will be typeset verbatim.
%
% For example, after telling \TeX
% \[|\verbatimspecials ⁄⁄ ⁄« ⁄» [ ⁄¿ ] [ ⁄›› ] {\def⁄›⁄|{$\vert$}}|\] (the
% slash is Unicode Fractional Slash, spaces are ignored) you
% can write \[\verb:|\macro⁄⁄arg⁄«arg. ⁄¿n+1⁄¿⁄»\⁄››[No⁄››]Value⁄››(T⁄⁄|F⁄››)|:\] to get
% \[|\macro⁄arg«arg. ¿n+1¿»\›[No›]Value›(T⁄|F›)|\]%^^A|
%%
%
% Note also that \verb+⁄⁄|+ is a~control sequence so it doesn't
% delimit the short verbatim \verb+|+'s argument.
%
% The \cmd\verbatimspecials\ declaration \acro{OCSR}. Subsequent uses
% of it override the previous settings. If you specified the optionals
% at first and then specify |\verbatimspecials| without optionals, the
% previous optional settings are forgotten.
%
% To turn the ‘verbatim specials’ off write
% \TextUsage\noverbatimspecials, which \acro{OCSR} too.
%
% Note that although we don't provide a~‘verbatim superscript’ nor
% ‘verbatim subscript’, you have the \TextUsage\sups\ and
% \TextUsage\subs\ \CS'es defined by \pk{gmutils}.
%
% The 4th argument for the math shift is optional because you can use
% \TextMarginize*{\( \)} \LaTeX's |\(| and |\)|.
%
% The |\verbatimspecials| declaration goes a~step further than
% \LaTeX's \TextUsage*{alltt} and Til Tantau's \pk{beamer}'s
% \TextUsage*{semiverbatim} environments. To get their effect, declare
%\[|\verbatimspecials\{}|\]
%
% \stanza
% There is something for verbatims in arguments of commands:
% \TextUsage\scanverb\arg*{text}. However there are some limitations:
% if |%| is the comment char (which is usual situation), then you
% cannot use |%| in \<text>, or rather, |%| will act as comment char
% anyway. Moreover, spaces are ignored. This last limitation may be
% worked around if you declare |\verbatimspecials|, say |⁄⁄| (fraction
% slash) as the escape char. Then you can use |⁄⁄ | to put a~space
% which will be typeset blank in the unstarred version and visible
% with star.
%
% \stanza Not so long ago I started to use the ‘broken bar’ (U+00A6,
% |¦|) character as a hyphen in hyperlinks, because it seems not to
% occur in hyperlinks at all unlike hyphen. I suggest the same char
% for verbatims, but if you don't like it, there's the
% \TextUsage\verbDiscretionaryHyphen declaration that takes two
% arguments. Broken bar is declared as
% \[|\verbDiscretionaryHyphen{"A6}{¦}|\]
%
% \stanza Since version 0.95 (August 2010) this package also provides
% the |\VerbatimPitch| declaration that modifies the \env{verbatim}
% environments and derivatives so that the environment contents
% (recatcoded, i.e.\ “sanitised”) are wrapped in the macro
% |\VerbatimContents| and therefore available after environment's end
% (after |\endverbatim| to be precise, so also in the end-def of a
% derivative verbatim).
%
% This may be useful for \TeX nical examples: you can  rescan the
% contents of a verbatim with |\scantokens| and execute/typeset it.
% Such a thing is done in the \pk{gmdoc} package, see the
% \env{verbatim@p} environment.
%
%
%
% \subdivision{The package options}
% As many good packages, this also does not support any options.
%
% \begin{gmlonely}
% \subdivision{Installation}
% 
% Unpack the \file{\jobname-tds.zip}
% archive (this is an archive that conforms the \acro{TDS} standard,
% see \file{CTAN/tds/tds.pdf}) in some texmf directory or just put
% the \pk{gmutils.sty} somewhere in the \file{texmf/\:tex/\:latex}
% branch. Creating a \file{texmf/\:tex/\:latex/\:gm} directory may
% be advisable if you consider using other packages written by me.
% 
% Then you should refresh your \TeX\ distribution's files' database
% most probably.
% \end{gmlonely}
% 
% \subdivision{Contents of the \pk{\jobname.zip} archive}
% 
% The distribution of the \pk{gmutils} package consists of the
% following three files and a \acro{TDS}-compliant archive.
% \begin{verse}
% \pk{\jobname.\gmdExt}\\
% \pk{README}\\
% \pk{\jobname.pdf}\\
% \pk{\jobname.tds.zip}
% \end{verse}
% 
% \begin{gmlonely}
% \subdivision{Compiling of the documentation}
% 
% The last of the above files (the \pk{.pdf}, i.e., \emph{this
% file}) is a documentation compiled from the \pk{.\gmdExt} file by
% running \LaTeX\ on the \pk{\jobname.\gmdExt} file twice
% (|xelatex ⁄jobname.⁄gmdExt| in the directory you wish the
% documentation to be in^^A
% \ifnum\numexpr\strcmp{\gmdExt}{sty}*\strcmp{cls}{\gmdExt}=0\relax^^A
%, you don't have copy the \file{.\gmdExt} file
% there, \TeX\ will find it\fi),
% then MakeIndex on the \file{\jobname.idx} file, and then \LaTeX\
% on \file{\jobname.\gmdExt} once more.
% 
%MakeIndex shell commands:
%\begin{verbatim}
%makeindex -r ⁄jobname
%makeindex -r -s gmglo.ist -o ⁄jobname.gls ⁄jobname.glo
%\end{verbatim}
% 
% The |-r| switch is to forbid MakeIndex to make implicit ranges since
% the (code line) numbers will be hyperlinks.
% 
% Compiling the documentation requires the packages:
% \pk{gmdoc} (\pk{gmdoc.sty} and \pk{gmdocc.cls}), \pk{gmverb.sty},
% the \pk{gmutils} bundle, \pk{gmiflink.sty}
% and also some standard packages:
% \pk{hyperref.sty}, \pk{color.sty}, \pk{geometry.sty},
% \pk{multicol.sty}, \pk{lmodern.sty}, \pk{fontenc.sty} that should
% be installed on your computer by default.
% 
% Moreover, you should put the \file{gmglo.ist} file, a MakeIndex
% style for the changes' history, into some \file{texmf/makeindex}
% (sub)directory.
% 
% Then you should refresh your \TeX\ distribution's files' database
% most probably.
% 
% If you had not installed the \pk{mwcls} classes (available on
% \acro{CTAN} and present in \TeX\ Live e.g.), the result of your
% compilation might differ a bit from the \pk{.pdf} provided in this
% \pk{.zip} archive in formatting: If you had not installed
% \pk{mwcls}, the standard \pk{article.cls} class would be used.
