How to control the current version of CVSROOT/modules ?

[mcarneir]

Hi.
Is it possible to roll back the version of the currently used CVSROOT/modules 
file?

Say that a product rev. A is built using "Ampersand modules".

Say that the product is updated to rev. B, and that the "Ampersand modules" is 
changed causing a change in the CVSROOT/modules file.

If I would want to roll back to rev. A, I would have to restore the previous 
version of the CVSROOT/modules file, to ensure that the "Ampersand modules" are 
defined correctly.
