I talked to Walter Tichy not too long ago, and he insists that RCS is NOT public
domain. It is distributed with BSD source, but that doesn't give one the right
to give the source to others. Also, part of RCS is covered by AT&T source
license. Perhaps we could get a definitive statement from the author?
