Introduction
When run without any arguments, wowace.py updates all your addons automatically. You can call it with specific addon names to update (or install) just those addons.
e.g. "wowace.py FuBar_QuestsFu" -- note that since the default is to fulfill dependencies and not use externals, this would also install FuBar, along any libraries that are required.
