Historian plus is also available under PRIMOS.  It is almost but not quite
compatible with SCOPE update.  (There are some special situations that we
were asked to look at once; however I no longer recall the details.)

I think the following is kosher under the laws of net.ettiquette since
it is information rather than a plug:

The Aide-De-Camp system, which SMDS markets, was developed and designed
by people who were familiar with and liked CDC update.  It has change
sets that are similar to CDC correction sets with the property of extending
changes across decks (er, make that files).  People who know CDC update
are usually quite comfortable with the ADC version control concepts.  It
is not, however, a translation of CDC update.  It was developed under UNIX
and is really quite different.

There a number of version control and configuration management products
on the market today that run under UNIX.  As far as version control is
concerned, most of them are SCCS or RCS clones with a superstructure.
As far as I know ADC is the only commercial product in the UNIX world
that has any kind of relationship to CDC Update.  If anyone has information
on another product that does, I would like to here about it.
