Module sharing and Tag usage

[Tietronix Optics]

Hi,
I've been using WinCVS for quite a long time now, and it works very
well to track SW activity.
Having developped several modules ( composed each one with
submodules) , I need now to export some submodules into others
projects in ordrer to use them
Up to now, I use the following procedure, but without being
satisfied :

Module A :
Use of submodules A1,A3,A5.

Module B :
Use of submodules B4


At the end of the development, I Tag submodules A1,A3,A5,B4 with the
tag "project1"



Some months later, I want to rebuild the project.

1st : Solution :
- Do a chekcout of module A with the tag project1
- Do a chekcout of module B with the tag project1
- remember how the submodules are sorted one against the other

2nd Solution :
- do a checkout of ??? with the tag project1.


How to proceed?

Thank a lot for your Help,
Cedric
