[Fedora-packaging] License landscape (and question of best pratice)

[Jose' Matos]

Hi,
	I have packed several R modules. R modules have a description file with a 
license field.
	Lots of those modules have as license: GPL version 2 or later.

	Should this be placed in the spec file as GPL or allow the fully license as 
described in the DESCRIPTION file?

	While searching for tags used in the License field for Extras I got this 
result:

$ grep -h ^License: */devel/*.spec | sed -e 's|License:||' | sed -e 's|^\s*||' 
 | sed -e 's|\s*$||' | sort | uniq -c | sort -nr
