Tammy, can you give a more detailed, concrete example of what CVS
snafu you've run into and how? That should help us give better
advice.
CVS has no "revert" mechanism per se. To back out any change you have
to commit the inverse of that change. (Which, in many cases, just
means yanking out the immediately previous revision and commiting that
again as the latest revision).
But, in your case basically what happened is you did a vendor import
of bad stuff? You did the vendor import, then after doing so,
realized it was bad, broken, or corrupted in some way? In that case,
I think all you need to do is retrieve the last known good
vendor import, vendor import that again, and you're fine. The bad
import will still be there in your CVS version history, but all its
changes will have been reversed.
So say you had good vendor import A, then bad vendor import B. Just
pull a clean checkout of the vendor import A out of CVS, exactly as if
you were making a release tarball of that vendor code, and then import
that again onto the vendor branch as vendor import C.
