@c How to use the math macros
@c ==========================
@c 
@c For simple expressions, simply use the @math{} command, e.g.
@c
@c     @math{\exp(x)/(1+x^2)}
@c 
@c but if the expression includes characters that need to be 'escaped'
@c in texinfo, like '{' or '}', or needs different output for TeX and info,
@c then use the following form,
@c
@c     blah blah blah @c{$y^{1+b} \le \pi$}
@c     @math{y^@{1+b@} <= \pi}
@c
@c The first part using @c{} must appear at the end of a line (it reads
@c up to the line end -- as far as texinfo is concerned it's actually
@c a 'comment').  The comment command @c has been modified to capture
@c a TeX expression which is output by the next @math.
@c
@c For ordinary comments use the @comment command.

% Mathematical macros taken from the GNU Calc Manual
% ==================================================
%
% Some special kludges to make TeX formatting prettier.
% Because makeinfo.c exists, we can't just define new commands.
% So instead, we take over little-used existing commands.
%
% Redefine @cite{text} to act like $text$ in regular TeX.
% Info will typeset this same as @samp{text}.
