Re: Remote cvs2svn

I'll strongly second Daniel's points here. cvs2svn was built entirely with
the idea of having the ,v files available for reading.

No, actually I believe it *is* technically impossible. IIRC, the "cvs log"
output does not fully detail the revision graph when branches are present.
It isn't always possible to determine the predecessor revision in certain
cases. And especially if somebody forces specific revision numbers -- you
can't just say "1.(rev-1)" to figure out the predecessor.

The ,v files, on the other hand, *do* contain all of the predecessor
information, so it can properly compute the branch graph for conversion.
