No.  From discussions half a year ago or longer, I thought that monotone 
was the preferred solution.  Git is easier, I suppose, because no one 
has to write anything to feed git-fast-import into monotone.  And 
a git-fast-import file would probably be the first step to get it into 
monotone anyway, since the direct cvs import I tried into monotone 
failed one of monotone's internal sanity checks.

Perhaps this means I don't have to do the cvs2mtn stuff any more.  Not 
for Modula 3, anyway.  Though git2mtn might still be useful for others.
