[gentoo-dev] Documentation licenses and license_groups

[Ulrich Mueller]

So far, the license_groups entries only contain software licenses,
but no documentation licenses like CCPL-Attribution-ShareAlike-3.0
or FDL-1.3. This has the strange consequence that most GNU software
cannot be installed if one sets ACCEPT_LICENSE="@FSF-APPROVED
@OSI-APPROVED", because the Texinfo manuals are typically licensed
under one of the GNU FDL variants.

Shouldn't all licenses listed at <http://www.fsf.org/licensing/licenses/>
(unless marked as non-free) be added to FSF-APPROVED? These would be
the following:

Free Documentation Licenses:

   FDL*
   OPL

Licenses for Works of Practical Use Besides Software and
Documentation:

   FDL*
   CCPL-Attribution-2.0 (and later versions? FSF mentions 2.0 only)
   CCPL-Attribution-ShareAlike-2.0 (and later versions?)
   DSL
   FreeArt

Licenses for Fonts:

   Arphic
   OFL*

Licenses for Works of Opinion and Judgment (maybe omit this group?):

   CCPL-Attribution-NoDerivs-3.0 (there's only 2.5 in ${PORTDIR}/licenses/)
   ("GNU Verbatim Copying License" - not yet in ${PORTDIR}/licenses/)

Alternatively, a new group like "FSF-APPROVED-NONSOFTWARE" (I'm sure
that a better name can be found ;-) could be introduced for the above.
