Yup, the tag command is how you make a branch.  Don't you need to
explicitly give the original revision too, though? i.e.

$ tla tag -S project--old--0 project--new--0

I wouldn't mind having a more streamlined approach for this.  The best
way I can think of to do it is something like:

$ tla apply-delta project--branch-apple--0--patch-123 
$ tla set-tree-version project--branch-cheese--0

This could be helped a bit with a script that used `tla logs` and `tla

Actually, wrappers like ABA or FAI probably already do this, I should
really get around to trying one at some point.  So far, my solution
has been to just keep multiple project trees lying around for
different branches so I don't need to switch between them so much.
