%%% mylatex.ltx
%%%
%%% Use this file to make a format based on the preamble of the
%%% LaTeX file abc.tex
%%%
%%% Use initex as follows:
%%%
%%% initex &latex mylatex.ltx abc (Generic TeX)
%%% initex \&latex mylatex.ltx abc (unix and other TeX's)
%%% tex /i &latex mylatex.ltx abc (emtex)
%%%
%%% This should make a format file mylatex.fmt which you can then use
%%% as follows
%%%
%%% tex &mylatex abc (generic TeX)
%%% virtex \&mylatex abc (Unix TeX)
%%%
%%% This will process your document, abc.tex, just as LaTeX does, but
%%% quicker as the contents of the preamble will be stored in the
%%% format file and will not need to be run each time.
%%%
%%% If (vir)tex fails to find your mylatex.fmt then it is not searching
%%% in the current directory, either modify your TEXFORMATS (or equivalent)
%%% path to search `.' or (on unix/dos) use ./ as in:
%%% virtex \&./mylatex abc
%%%
%%%
%%% The file abc.tex must contain a line *just* with
%%% \begin{document}
%%% (In particular no comments on that line.)
%%% Everything up to (but not including) the \begin{document} will
%%% be saved in the format and not executed in subsequent runs.

%%% incompatibility with \makeindex command.
