Newbie question : common/shared objects

[Jay Yarbrough]

I'm quite new to using CVS.

Our applications rely on common source, and built products alike.

Some of these are 3rd party (dlls, jars, source, etc.) and some are internally 
developed.

For instance, to build release 1.2 of product X, I need release 3.4 of product 
A, release 5.4 of product B, and release 1.1 of product C.  

To build release 2.1 of Product Y, I will use release 3.4 of product A, release 
5.3 of product B, and release 2.0 of product D.


How is this typically handled within CVS?

TIA,
Jay
