The following is a commentary on CVS vs PRCS from Stig, one of the Xemacs
programmers (off-topic I'll admit, except for the fervent hope that we all
have our source trees under some form of version control):

What's involved?
Isn't that just a problem of building against the wrong library?

Not yet, but it's planned for "real soon now." Not all applications
require client/server, even though it is the hot buzzword.
CVS doesn't understand file name changes and file removals.
CVS has a really bone-headed "vendor branch" mechanism that causes a
perpetual hell of unnecessary merges once
CVS is really incredibly SLOW. If you tag a version of a big source tree
(like XEmacs, for instance), CVS will have to rewrite every single file in
the whole repository in it's entirety. Does such a conceptually simple
operation really warrant the pushing-around of 120 megabytes?
CVS is a DOG.

Problems with the broken meta-data in CVS repositories are enough reason
to use PRCS right now, so long as you can wait a while for client/server.
Also, PRCS handles meta-data more efficiently than CVS and claims 2X-6X
performance gains for most common operations. It does have one
pathetically slow operation that can probably be more accurately be
described as a lingering bug than a design problem, but that's just the
initial checkin.
