Or hindfront, or something.  RCS.  That's...impressive.

Most of the venerably ancient project histories I've converted only
have the following geological strata

1. Subversion
2. Random crap generated by cvs2svn
3. CVS

Layer 2 is the nasty one.  Those conversion artifacts tend to trip up
Subversion-to-anything converters, especially git-svn. I originally
wrote reposurgeon to have a way to clean those up.

What I've never seen before is a plain RCS layer visible below the CVS
(now that I've been clued in some things in older ChangeLogs make sense.) I
guess that's because there just aren't that many projects old enough to
predate CVS.  Only three out of over forty of mine are.

/me wouldn't be surprised to stumble over a fossil trilobite next.
