% -*-LaTeX-*-
% TROFFMS.STY for tr2latex - troff to latex translator
% These macros are intended to be referenced by a LaTeX
% \documentstyle[troffms,twoside]{article}
% command.  You can insert an 11pt or 12pt option if you like larger
% type--sizes set here are computed from the LaTeX point size setting.
% You need these macros since they are refered to by the translator.
% You can modify them if you want.
% I would very much want better macros for the headers and footers.
% Please pass your suggestions to me.           -Christian
