cvs and gnats link?

[Schwenk, Jeanie]

We had a bug that toasted some product (see many $$ here).  Now management
wants a "formal" system of notification, complete with reports and and
appropriate sign off when changes take place.  With absolutely nothing for a
budget of course.  This sweeping bureacracy change is to include a bug
tracking system.   I've been looking at GNATS and would like to know if CVS
and GNATS can be linked.  From a developer standpoint, it would be most
convenient and less error prone to type the same information once rather
than twice.  I ran across a statement that ClearCase and GNATS could be
linked but didn't find any evidence to support it.   I'm also looking at
Bugzilla and Jitterbug.  What do you use?  Any recommendations?
