Here are some things that would be useful additions to groff: ideal preprocessor -mv macros (for typesetting viewgraphs and slides) a deroff that understands long names a page-makeup postprocessor and associated macro package (like pm and -mpm) a complete, self-contained manual -- first results can be found in doc/groff.texinfo. If you want to work on one of these, you should probably post to gnu.groff.bug to see if anyone else has gotten there first.
