%A Burkhard Höfling
%%
%%
%% DO NOT RELY ON MACRO DEFINITIONS IN THIS FILE!
%% The official definition of the manual style is to be found in the file
%% `gapmacrodoc.tex'.
%%
%% The following macros are defined in this file.
%%
%% `text' set text in typewriter style (use `\<' instead of `<')
%% <text> set text in italics (use $\<$ instead of $<$ for less than)
%% *text* set text in emphasized style (i.e. slanted)
%% $a.b$ same as $a \cdot b$ (use $\.$ instead of $.$ for full stop)
%% "ref" refer to a label (like "function!for category")
%% \pif sets a single '
%% \cite{.} make a citation
%% \index{.} \indextt{.} make index entry (\indextt in typewriter style)
%%
%% \beginitems produce itemized texts with 3pc hanging indentation
%% item & text
%%
%% item & text ...
%% \enditems
%%
%% \begintt verbatim text in typewriter style
%% verbatim material
%% \endtt
%% \beginexample verbatim text in typewriter style
%% verbatim material
%% \endexample
%%
%% \Input{file} includes file `file.tex'
%% \Chapter{title} followed by a blank line
%% \Section{title} followed by a blank line
%% make chapter or section title. Automatically generates table of
%% contents. \null after \Section{...} inhibits indexing.
%% \>function( arguments )!{ index subentry }
%% \>`a binop b'{binary operation}!{ index subentry }
%% make a heading for a subsection explaining a function or a binary
%% operation. This automatically generates a label and an index entry
%% (with optional subentry).
%% \){\fmark ...}
%% the same without label and index entry
%%
%% \URL{url}
%% \Mailto{}
%%
%% \BeginningOfBook
%% \FrontMatter, \Chapters, \Appendices, \EndMatter parts of the book
%% \Bibliography, \Index, \TableOfContents make these chapters (w/o head)
%% \EndOfBook
%%
%% The following macros can be used just after inputting gapmacro.tex to control
%% the layout.
%% \casesensitivetrue makes labels case sensitive (this is still experimental
%% and not currently supported by the html converter)
%% \casesensitivefalse & (default) labels are case insensitive
%%
%% \addlinks (default) This inserts pdf links within the document, so
%% that you can click on a reference or citation. This will only work
%% with pdftex, otherwise this has no effect.
%%
%% \nolinks This switches off additional pdf links within the document.
%%
%% \citebookstrue References to external books will be
%% "GAP Reference Manual, 2.7.12" instead of just "2.7.12", similarly
%% for the GAP tutorial. If you cite other books, you have to define
%% macros \xxxManual which must expand to the text which you want to
%% be inserted before the number for package xxx (lower case).
%% \citebooksfalse (default) just print the number
%%
%% \usepsfonts (default) use the standard Postscript fonts for typesetting
%% \usecmfonts use the TeX standard fonts
%%
%% \biblitemfalse (default) In the bibliography, print abbreviations for
%% papers right-aligned (as in gapmacro.tex)
%% \biblitemtrue print abbreviations left-aligned
%% \bibindent (default: 3 pc) indentation used in the bibliography -
%% depending
%% on the abbreviations you use, you may need more (this is not very
%% obvious if you use \biblitemfalse because long abbreviations will
%% protrude into the left margin only, but will cause overfull hboxes
%% when using \biblitemtrue

% Macros which write labels, citations and index entries on auxiliary files.
%
% 1. Some code was moved around so that all the labels and indexing stuff
% would be together.
% 2. Modified \makelabel, \printref and \label to be more like the LaTeX
% commands \newlabel, \ref and \label, respectively. The commands:
% \@xp, \@firstoftwo, \@secondoftwo, \namedef, \@ifundefined
% \protectedwrite are adapted pieces of LaTeX code (\@xp is actually
% AmSLaTeX's abbreviation of \expandafter).
% 3. The upshot of 2. is that now underscore is allowed in labels and
% index-entries and that the \makelabel commands written to the
% manual.lab files have arguments that are no longer put in lowercase.
% The labels formed inside TeX from the \makelabel commands maps
% underscores to | (needed to be a non-active character) and then
% converts to lowercase.
% 4. Since GapDoc uses < and > in some of its labels a temporary re-defintion
% of <#1> was necessary, inside \@xplowr.
