IIRC (I was looking at the hook code for another reason) the hook is run
after the event in question.

At the moment (tla
address@hidden/dists--release-tla--1.1--patch-5(emf.net/devo.tla.release)
from regexps.com), tla doesn't examine the return code from the hook to
make that decision.  Given that the hook is run *after* the event, there's
really not much reason to check.

Pre-event hooks are another story and I'm sure that Tom will do/allow the
Right Thing (TM) in those cases when/if those hooks are added.

I was relatively happy with CVS, but once I started to use larch/tla I
haven't considered using CVS for anything that I do.  In some respects, I
think that it is superior to ClearCase.  (Given my useage patterns, at any
rate.)
