a) Fair enough.  I only used it because Judd used it.

b) The first one that comes to mind would be a
python/jython/ironpython/pypy example.  Python programs can be written
against python 2.5, but jython only supports python 2.2 (so it would
provide=('python-2.2')).  Pypy 0.99.0 provides python-2.5 (I believe).

Same sort of thing for java with kaffe, jre, gcj, etc.

If you think of a group of provisions, any time a fundamental change
happens to the entire group, you'd probably want a new version number.
