Looking at the uses of 'weak' on that page suggests that to the FSF,
at least, a weak copyleft license is one that permits the licensed
work to be incorporated in a larger proprietary work, whereas a
strong copyleft license does not (at least in the FSF's opinion).
This seems an appropriate distinction for general use.

Neither of these should be confused with Grave and Perilous Licenses.

No,  John.  I want formats that are actually useful, rather than over-
featured megaliths that address all questions by piling on ridiculous
internal links in forms which are hideously over-complex.
