I always thought the standard was:
   "lib is for libraries and share is for datafiles"
rather than
   "lib is for platform-dependent and share is for platform independent".

Actually, the standard itself is confusing as where
to put platform-dependent datafiles.

The example in Makefile.example could refer to
either "compile examples" or "here is an example
makefile that you can use as a starting point".
