David, I really love your opinions on branching. I completely agree with
everything.

As far as externals go, how do you feel about those? I think your opinion
would be very valuable.

It seem so far the consensus is that externals are very appropriate for my
specific case. In the past, I've created a python script that used PySVN to
search the current working copy and replace any externals with an actual SVN
Copy and then create a tag out of that. So while our 'trunk' uses externals,
the tags do not. The tags reflect what a working copy would look like. We
did this because if we ever were to have an external that referenced an
outside repository that we had no control over, we wanted to make sure that
a year after the tag was made that the repository didn't somehow get
disconnected. Repositories becoming unavailable is another good reason why
externals should not exist in tags, however when the externals are relative
this is a non-issue.
