I belive that it's possible to implement specificity comparison without
looking at the source tree.
Consider a glob parser that counts how many characters of the filename
are matched using literals in the glob ("[a-zA-Z]"), how many are
matched using ? and how many using *. The comparison is then using the
perl <=> operator:
literalsA <=> literalsB ||
questionsA <=> questionsB ||
starsA <=> starsB ||
disambiguateA <=> disambiguateB
The disambiguation function needs to handle cases where two globs
somehow still matched equally. For example, for file "foo", "f??" and "?o?"
both match equal numbers of liternals and questions. Seems that something
arbitrary has to be done here, but it can be as simple as saying that the
glob with the most specific leftmost side is most specific. (Leaving
definition of "leftmost" to the implementor, because I have to run.)

Yeah, on second thought I sorta prefer the example above, of sticking
the boilerplate in the extended description. This assumes that licenses
with an extended description can still be standard licenses.
