% The following few pages contain LaTeX programming extensions adapted
% from the ZzTeX macro package.
% Token Hackery
% ----- -------
\def \@expandaftertwice {\expandafter\expandafter\expandafter}
\def \@expandafterthrice {\expandafter\expandafter\expandafter\expandafter
\expandafter\expandafter\expandafter}
% This macro discards the next token.
\def \@discardtok #1{}% token
% This macro removes the `pt' following a dimension.
{\catcode `\p = 12 \catcode `\t = 12
\gdef \@remover #1pt{#1}
} % \catcode
% This macro extracts the contents of a macro and returns it as plain text.
% Usage: \expandafter\@defof \meaning\macro\@mark
\def \@defof #1:->#2\@mark{#2}
% Control Sequence Names
% ------- -------- -----

% The boolean literals \@true and \@false are appropriate for use with
% the \if command, which tests the codes of the next two characters.

\def \@setflag #1=#2{\edef #1{#2}}% \flag = boolean
% IF and Predicates
% -- --- ----------
% A "predicate" is a macro that returns \@true or \@false as its value.
% Such values are suitable for use with the \if conditional. For example:
%
% \if \@oddp{\x} <then-clause> \else <else-clause> \fi
% A predicate can be used with \@setflag as follows:
%
% \@setflag \flag = {<predicate>}
% Here are the predicates for TeX's repertoire of conditional
% commands. These might be more appropriately interspersed with
% other definitions in this module, but what the heck.
% Some additional "obvious" predicates are defined.
