   The Eclipse Public License is similar to the Common Public License, and
   our comments on the CPL apply equally to the EPL.

http://www.gnu.org/licenses/license-list.html#CommonPublicLicense10

   This is a free software license. Unfortunately, its weak copyleft and
   choice of law clause make it incompatible with the GNU GPL.

So I'm not sure you can distribute it anywhere...

If the EPL piece is used as a library, you may need to read
http://www.gnu.org/licenses/gpl-faq.html#FSWithNFLibs

(But this is unrelated to Emacs and ELPA, so this may not be the best
place to get answers to such questions.)

This has been asked a few times; I'm not sure I've ever seen a
definitive answer. Ref eg
