%  mTeXsis - mini version of the TeX Macros for Physicists
%
%  This is mtexsis.tex, a "mini" version of the TeXsis macro package
%  containing only the core TeXsis macros.  You can get the full
%  version of TeXsis, with complete documentation, from ftp://ftp.texsis.org/
%
%  If you receive a manuscript file prepared with TeXsis you can
%  (usually) print it by inserting the line
%
%       \input mtexsis
%
%  at the begining of the manuscript file (before \texsis, if it
%  is there) and then running it through Plain TeX.
%
%  Authors who prepare papers with TeXsis for submission to the Los
%  Alamos e-print archives should try their  manuscripts with Plain
%  TeX and mtexsis.tex to be sure that it works.  You can also make your
%  file automatically work with either TeXsis or Plain and mtexsis by
%  putting the following at the begining of your manuscript file (in
%  place of just \texsis): 
%
%	\ifx\texsis\undefined\input mtexsis\else\texsis\fi
%
%  If you want to know how a macro works you will have to look in the
%  full TeXsis source files.  There are copious comments.
%
%  Comments, suggestions, or bug reports should be directed to 
%  texsis@umich.edu.
