Our company has two sites working on the same code. We create patch
files to distribute our local changes to the remote site. I have had
to hack up a shell script for rcsdiff (doing it all by hand) s.t.
$keyword differences are ignored (since our $Source$, $Header$, and
$Log$ expansions are usually slightly different). A switch to rcsdiff
which somehow ignored such differences would be nice. A "good" way
would be for the $Log$ entries never to be expanded in the ,v file, but
built up everytime you co'd the file. A switch to co would *not*
expand keywords - thus, rcsdiff could co the two versions to be diff'd
with this switch set and do a diff on them. Clearly such diff's should
be applied to a similarly co'd file - perhaps a command/method to
convert expanded $keyword's to their unexpanded versions would handle
this and the rcsdiff "problem". Obviously $Log$ is the tricky one
since it is multi-line and not clearly delineated - I have handled it
by assuming that ALL lines following $Log which start with the $Log
prefix + a space (eg. " * " or "# ") are $Log lines - works OK for us.
Apart from this, I too prefer RCS to SCCS (not that SCCS would
necessarily be any better than RCS in this regard!). cheers ...
