It appears that when adding any new license, one needs to send a notice to gentoo-dev. I have added CCPL-Attribution-2.5 (see attachment or http://creativecommons.org/licenses/by/2.5/legalcode) and added it to the FREE-DOCUMENTS license group (same as CCPL-Attribution-3.0, acked by Robin Jonson)*. The license is required for some files that are part of a package that I am adding to the tree (games-util/pyfa).
Since CCPL-Attribution-2.5 is an obviously free documentation license, and since CCPL-Attribution-2.0 and 3.0 and CCPL-Attribution-ShareAlike-2.5 are already in licenses/, I assume that this addition is uncontroversial. [*] FREE-DOCUMENTS and not FSF-APPROVED-OTHER because the only version of CCPL-Attribution that is explicitly listed as approved by the FSF is 2.0 (see http://www.gnu.org/licenses/license-list.html). -Alexandre.
