Refcard files

[Eli Zaretskii]

People are committing changes to the various *-refcard.tex files, but
the corresponding *.ps files are not regenerated.  Since reading the
PostScript files requires the knowledge of the language in which it
was written, and since (AFAIK) producing some .ps files needs a
special setup of TeX and dvips, I think people who modify the TeX
sources should also take care of regenerating and committing the
PostScript files.

TIA
