You'll have to remind me what you mean by "incremental" here. Possibly
it's something cvs-fast-export could support.

But what I'm trying to tell you is that, even after I've done a dozen
releases and fixed the worst problems I could find, cvsps is far too
likely to mangle anything that passes through it.  The idea that you
are preserving *anything* valuable by sticking with it is a mirage.

I fear those "lots of projects" have subtly damaged repository
histories, then.  I warned about this problem a year ago; today I
found out it is much worse than I knew then, in fact so bad that I
cannot responsibly do anything but try to get cvsps turfed out of use
*as soon as possible*.

And no, that should *not* wait on cvs-fast-export getting better 
support for "incremental" or any other legacy feature.  Every week
that cvsps remains the git project's choice is another week in which
somebody's project history is likely to get trashed.

This feels very strange and unpleasant.  I've never had to shoot one
of my own projects through the head before.

I blogged about it: http://esr.ibiblio.org/?p=5167

Ignore the malware warning. It's triggered by something else on ibiblio.org;
they're fixing it.
