[Incubator] PyWPS copyright and license headers requirement

[Tom Kralidis]

Hi all: we are discussing the requirement of copyright/license headers
as part of PyWPS incubation [1] and as a result looking for clarification.

The FAQ in [2] says that we need this for every source file.  While I
fully agree with this practice there are questions and examples of
other 'serious' (<- my word :) projects which do not adhere to this, like
the Django project (e.g. in [3]).

Thoughts?  Am I (aside from my personal preference of always having these
headers) interpreting this requirement incorrectly?  If not, is there
background/context which roots the requirement?

Please advise.

Thanks

..Tom
