cvs2p4: initial import of openrcs from OpenBSD src tree
These sources are pretty much current as of Oct 7, 2006, 10:25 p.m.
(Pacific Time.)
Also removing the RCS-5.7 patch(es) because the RCS-5.7 archive is GPL
and the licensing terms make it difficult (impossible?) to include RCS in
its entirety for further redistribution w/ cvs2p4.
To come: diffs to get OpenRCS to print out compatible output for
cvs2p4's requirements.
