OK. Not sure how I missed this, but I've been wildly multi-tasking
lately.

The only way I think we can sanely handle this case is like this:

A. Does the License Tag string match an entry in the License list?
 [Yes] Stop, its fine.
 [No] Goto B.
B. Does the License Tag have any parenthesis in it?
 [Yes] Goto C.
 [No] Goto D.
C. Find parenthesis wrapped strings, make them into substrings. For each
substring, goto D.
D. Parse string through regex. Does each remaining item (things not
regexed to /dev/null) match an entry in the License list?
 [Yes] Do nothing, keep looking until we're out of strings. 
 [No] Print out the non-matching item. Keep looking until we're out of
strings.

Anyone want to take a crack at coding that in python? (Or propose a
better method?)

Ahh. I'll fix that right now.
