Thanks.  This will make automatic updates possible.

But here i disagree.  SCCS is a POSIX tool that works pretty good,
especially if you do TZ=UTC before you use it.  And especially for
such a small project like this one, with only one (or two)
committers.  With nice uuencoded binary data :).  I like SCCS.

Jörg Schilling includes a pretty good RCS->SCCS converter in his
SCCS distribution, if you use it in exactly the way he had in mind.
(I do use the older SUN/Heirloom one, only half the size and
pretty much self-containing, though.  *Much* easier to compile.)
I think going the other way should be a little bit easier due to
the POSIX standard -i and -l options to get(1)?

What a pity.  Cold comfort for change.
