cvs is not gnu

[Karl Berry]

Hi Thien-Thi,

In the Overview node of rcs.texi (thanks for making the Texinfo, by the
way), I see:

       If you use RCS heavily, you may also be interested in GNU CVS
    (http://www.gnu.org/software/cvs/).

1) CVS is not a GNU package, although this has been a source of
longstanding confusion.  These days, the cited www.gnu.org url just
redirects to http://www.nongnu.org/cvs.

2) The statement seems misleading to me.  It implies that CVS is somehow
an advanced or related version of RCS.  But, as you know, in reality it
is a completely different VC paradigm and CVS has no actual relationship
to RCS except for what amounts to an implementation detail.  How about
something like this:

  RCS works with versions stored on a single filesystem or machine,
  edited by one person at a time.  Other version control systems, such
  as Bazaar (@url{http:///www.gnu.org/software/bazaar}), CVS,
  Subversion, and Git, support distributed access in various ways.
  Which is more appropriate depends on the task at hand.

(I suggest giving the url for bazaar but not the others because it is
only one besides RCS that is a GNU package.  It's not like any of them
are hard to find, anyway.)

Thanks,
karl
