Ah. Right. I did think your way was a bit weird.

You could use modules2 to alias common code... in each module, you use
CVSROOT/modules2 so that a sub-module  is aliased to a master module that
contains common code... you'll reduce the amount of duplication, but it can
be tricky to get things working that way.

Or do as Glen suggested earlier and use the branching strategy instead.

Or even do a combination of the two.

Basically, play around on a test system and use whichever works and is
comfortable for you.
