How to control the current version of CVSROOT/modules ?

[Michael da Costa Carneiro]

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

Say that sw release 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.

Regards
Michael
