Frans,

My original version of this patch was just changing GPL to GPLv2 for example.  But I was asked about whether it should be GPLv2+ which I guess is more indicative of the "or later" clause.  Does anyone have good guidance here on how to denote things that are GPLv2 only for now (like git which Linux has a note in the COPYING file about it being GPLv2) and things that are GPLv2 or later version?  I'm trying for consistency here but I guess there doesn't seem to be a set policy for how the LICENSE field should be set.
