GNU chem maintenance

[G. Branden Robinson]

Since a couple of threads are going on the subject of formatting
chemical diagrams with groff...

Would someone like to volunteer to take over maintenance of GNU chem?

It's one of several preprocessors formerly maintained by Bernd Warken,
but he's been gone for a long time.  It's been my intention to work on
it and address some open bugs, but I have managed to keep myself pretty
busy with other aspects of groff and feel close to saturated.

Bernd's version of chem is written in Perl.  He placed it under the GNU
GPL, version 2.  It's a "contrib" project.

  Files in the contrib/ subdirectory of the source distribution are not
  strictly part of groff.  That is, they are distributed with it and are
  Free Software <https://www.gnu.org/philosophy/free-sw.en.html>, but
  they are not considered essential parts of the distribution.  Further,
  they may bear licenses other than the GPL or the FSF does not
  administer their copyrights.  To determine their copyright status and
  licensing, see the "COPYRIGHT" file in the appropriate subdirectory of
  contrib/.

Any takers?

Regards,
Branden
