Hi all,

I think for the common licences, we should also add BSD licence... for example my pkg randtoolbox (which is currently with incompatible licences) will probably be in a near future with the BSD licence.

Anyway I like the idea of two different repositories for GPL like licensed pkg and other packages.

This would be helpful. I would just reemphasize that a package that
includes some AGPL code and some GPL3 code is standard as far as the FSF
is concerned, e.g. from section 13 of the AGPL:

"Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU General Public License into a single combined work, and to convey the resulting work. The terms of this License will
continue to apply to the part which is the covered work, but the work
with which it is combined will remain governed by version 3 of the GNU
General Public License."

So, I think that CRAN should at least have a canonical spec that covers
*this* situation. Other situations may be more complicated to handle
elegantly.

Another possibility is to simply standardize the set of licenses that CRAN
supports.  GPL licenses (GPl-2, GPL-2.1, GPL-3, LGPL), MIT and
X11 already cover 98% of all packages on CRAN.   If there truly is an
advantage to the AGPL license perhaps a standard version could be offered in the set. Perhaps, for the 2% of packages that want a different license
a second repository could be made available.
