Emacs help for 'cvs commit'?

[J Krugman]

I am relatively new to cvs (and to any form of version control
software).  One thing that seems harder than it should be is that
when one executes a "cvs commit", and cvs prompts one for a message
to describe the changes made, cvs doesn't provide an easy way to
review the differences between the new revision and the previous
one; I end up having to rely on my notoriously bad memory.  Does
Emacs' CVS support provide any facility to do this?

Thanks!
