1. Definitions.

   "You" (or "Your") shall mean the copyright owner or legal entity
   authorized by the copyright owner that is making this Agreement
   with the Foundation. For legal entities, the entity making a
   Contribution and all other entities that control, are controlled
   by, or are under common control with that entity are considered to
   be a single Contributor. For the purposes of this definition,
   "control" means (i) the power, direct or indirect, to cause the
   direction or management of such entity, whether by contract or
   otherwise, or (ii) ownership of fifty percent (50%) or more of the
   outstanding shares, or (iii) beneficial ownership of such entity.

   "Contribution" shall mean any original work of authorship,
   including any modifications or additions to an existing work, that
   is intentionally submitted by You to the Foundation for inclusion
   in, or documentation of, any of the products owned or managed by
   the Foundation (the "Work"). For the purposes of this definition,
   "submitted" means any form of electronic, verbal, or written
   communication sent to the Foundation or its representatives,
   including but not limited to communication on electronic mailing
   lists, source code control systems, and issue tracking systems that
   are managed by, or on behalf of, the Foundation for the purpose of
   discussing and improving the Work, but excluding communication that
   is conspicuously marked or otherwise designated in writing by You
   as "Not a Contribution."

3. Grant of Patent License. Subject to the terms and conditions of
   this Agreement, You hereby grant to the Foundation and to
   recipients of software distributed by the Foundation a perpetual,
   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
   (except as stated in this section) patent license to make, have
   made, use, offer to sell, sell, import, and otherwise transfer the
   Work, where such license applies only to those patent claims
   licensable by You that are necessarily infringed by Your
   Contribution(s) alone or by combination of Your Contribution(s)
   with the Work to which such Contribution(s) was submitted. If any
   entity institutes patent litigation against You or any other entity
   (including a cross-claim or counterclaim in a lawsuit) alleging
   that your Contribution, or the Work to which you have contributed,
   constitutes direct or contributory patent infringement, then any
   patent licenses granted to that entity under this Agreement for
   that Contribution or Work shall terminate as of the date such
   litigation is filed.

5. You represent that each of Your Contributions is Your original
   creation (see section 7 for submissions on behalf of others).  You
   represent that Your Contribution submissions include complete
   details of any third-party license or other restriction (including,
   but not limited to, related patents and trademarks) of which you
   are personally aware and which are associated with any part of Your
   Contributions.

7. Should You wish to submit work that is not Your original creation,
   You may submit it to the Foundation separately from any
   Contribution, identifying the complete details of its source and of
   any license or other restriction (including, but not limited to,
   related patents, trademarks, and license agreements) of which you
   are personally aware, and conspicuously marking the work as
   "Submitted on behalf of a third-party: [named here]".
