It seems to work for me.  I'm still sanity checking the results.

Performance is indeed horrible for the remote case.  I don't know how
horrible it would be for someone in a sane environment, since I'm behind
one of SBC's DSL gateways, which thinks (emphasis on "thinks") it is a
nameserver.

The script produced by cvs2git checks out every revision of every file,
right?  Would "cvsps -g -p<dir>" improve cvs2git?  I don't think it
would help performance (it checks out the files to generate the patchset
diffs (?)), but making the ugly someone else's problem is always good.
Also, what about -x, to force cvsps to regenerate it's cached idea of
the repository's patchsets?

cvsps seems a little weak on the whole error message idea (misspelling
cvsroot leads to complaints about CVS versions).
