Purge old files in CVS?

[Matthias Kaeppler]

Hi,

I have set up a CVS repository on a server where I 
only have 100MB quota.
In order to avoid letting the repo grow 
infinitely, is there a mechanism to tell CVS that 
it should purge all diffs before date X, in order 
to save space? I mean, I don't need changes made 6 
months ago anyway, so I can as well get rid of the 
changelogs and diff-files.

Regards,
Matthias
