What does 'sorcery default add' do?  sorcery --help didn't give me a very 
clear description.  Maybe it's what I want.

What I meant was that when you cast a spell that has previously had it's 
optional dependencies chosen it prompts you if you would like to continue 
using what you selected.  Since this rarely ever changes it should only 
need to come up the first time you cast the spell, use cast -r, or when 
the optional dependency isn't installed.

The problem is that if you cast 
xorg-server and something else casts that has an optional depends on xorg 
and you aren't there to watch everything scroll by you will miss it and 
xorg will be installed which can stomp xorg-modular (this happened to me a 
few weeks ago).  So maybe in the case where xorg-server has been installed 
and xorg has been uninstalled anything that optionally depended upon xorg 
should then depend on xorg-server since it's the only spell that fills 
that PROVIDES.
