cvs conversion with ConvertExtension - branches/versions in CVS require merging

[Richard Murray]

Thanks!  I've just tried running your cvs2hg but get a Python error, see
below.  I'm running on Solaris 10, with Python 2.6 and Mercurial 1.5.4.

I don't know Python at all, could you advise?  

Incidentally this is the same issue I get trying to run the standard cvs2svn
tool (which I've raised on the cvs2svn mailing list here
http://cvs2svn.tigris.org/ds/viewMessage.do?dsForumId=1670&dsMessageId=263282
2)

Unfortunately, 'hg convert' does not really handle CVS branches and
tags in their full insane generality.  That's because it's based on
cvsps, which does not fully handle CVS branches or tags.

Only cvs2svn really understands CVS in all its madness.  I wrote a new
hg backend for cvs2svn that has not been merged in upstream, but it's
pretty good.  Just clone http://hg.gerg.ca/cvs2svn, read
README.csv2hg, and have fun.  Good luck!  Getting a good conversion
out of CVS is not trivial.
