Re: Tags and externals

You don't really want externals in this case. All you really want to
do is to copy (branch) the common code into the release. In fact, you
probably want to do this anyway, even on the trunk, and not use
externals at all. Externals have the 'advantage" of auto update
propogation, but as you discovered, this really isnt the advantage
that is appears.

So, just copy from Common into an appropriate location in Prod_A and
Prod_B. Then use the merging features of Subversion to perform
updates from Common into the products as and when desired.
