Although Cabal's documentation only mentions 'getDataFileName' [1],
the API states that the Paths module should "enable [the packages] to
find their version number" [2].  So that's the intended use, even if
not very well documented.  Just remember to put the Paths in
'other-modules' [1].

Cheers! =)
