Missing admin password

[mika]

In a move of stunning managerial brilliance, the company I'm at fired
the only person with the administrator password to our CVS, without
getting the password from him.  (Evidently the idea of asking
developers to document what they do is an alien concept here.)  Given
that he was not only fired, he was fired over something petty and
trivial, he's not inclined at this point to give anyone here the
password at this point.  Is there a way to get into this CVS tree, or
is starting over the only option?
