Well, I find that Eric tends to be pretty reliable, and I have to say
that I cannot think of a logical reason why setup *wouldn't* use this
method. It makes no sense not to - you'd have to add yet another set of
information to setup for it to know if a version was newer.
I sincerely doubt that the original setup developers obfuscated it
*that* much. The version number is the best way of doing things.. If
things change, generally the package name changes slightly as well, and
you just make the new one replace the old...
(NB: I'm not 100% sure w/o referring to earlier messages that it was
Eric that originally posted this (in this thread), but I'm pretty sure
it was.)
Anyway.
Chris
