Daniel,

Apparently you just copy the whole source tree from the "trunk" directory
into an appropriately named directory under the "branch" directory.  No
special commandline options or anything like that.  Apparently SVN
maintains these copies efficiently (not copying actual data, just pointers).

I haven't lived in that regime yet, but hopefully it will be straight
forward.

CVS branches aren't really *all* that bad, and I've managed to handle
work with them in mapserver.  But it took me years!

That is correct.  You need to mark files specially to tell them to
expand special variables.  Bob Bray wrote up a bit of info on how to
have SVN clients do some of this automatically for new files.

I imagine most of this would apply to us as well.
