% These macros are intended to be referenced by a LaTeX
% \documentstyle[troffman,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.
% Size values have been chosen to closely match Unix manual page
% documents, which are actually too wide and too high for good
% typographic taste and readability.
