Google Software Grant and Corporate Contributor License Agreement

In order to clarify the intellectual property license granted with Contributions
from any person or entity, Google LLC ("Google") must have a Contributor License
Agreement (CLA) on file that has been signed by each Contributor, indicating
agreement to the license terms below. This license is for your protection as
a Contributor as well as the protection of Google and its users; it does not
change your rights to use your own Contributions for any other purpose.

This version of the Agreement allows an entity (the "Corporation") to submit
Contributions to Google, to authorize Contributions submitted by its designated
employees to Google, and to grant copyright and patent licenses thereto.

You accept and agree to the following terms and conditions for Your present
and future Contributions submitted to Google. Except for the license granted
herein to Google and recipients of software distributed by Google, You reserve
all right, title, and interest in and to Your Contributions.

    Definitions.

"You" (or "Your") shall mean the copyright owner or legal entity authorized
by the copyright owner that is making this Agreement with Google. 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 the code, documentation or any original work of authorship,
including any modifications or additions to an existing work, that is intentionally
submitted by You to Google for inclusion in, or documentation of, any of the
products owned or managed by Google (the "Work"). For the purposes of this definition,
"submitted" means any form of electronic, verbal, or written communication sent
to Google 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, Google 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."

Grant of Copyright License. Subject to the terms and conditions of this Agreement,
You hereby grant to Google and to recipients of software distributed by Google
a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable
copyright license to reproduce, prepare derivative works of, publicly display,
publicly perform, sublicense, and distribute Your Contributions and such derivative
works.

Grant of Patent License. Subject to the terms and conditions of this Agreement,
You hereby grant to Google and to recipients of software distributed by Google
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.

You represent that You are legally entitled to grant the above license. You
represent further that each employee of the Corporation designated by You is
authorized to submit Contributions on behalf of the Corporation.

You represent that each of Your Contributions is Your original creation (see
section 7 for submissions on behalf of others).

You are not expected to provide support for Your Contributions, except to the
extent You desire to provide support. You may provide support for free, for
a fee, or not at all. Unless required by applicable law or agreed to in writing,
You provide Your Contributions on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS
OF ANY KIND, either express or implied, including, without limitation, any warranties
or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE.

Should You wish to submit work that is not Your original creation, You may submit
it to Google 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]".

It is your responsibility to notify Google when any change is required to the
list of designated employees authorized to submit Contributions on behalf of
the Corporation, or to the Corporation's Point of Contact with Google.
