"Work" shall mean the work of authorship, whether in Source or Object form,
made available under the License, as indicated by a copyright notice that
is included in or attached to the work (an example is provided in the
Appendix below).

"Derivative Works" shall mean any work, whether in Source or Object form,
that is based on (or derived from) the Work and for which the editorial
revisions, annotations, elaborations, or other modifications represent,

License, Derivative Works shall not include works that remain separable
from, or merely link (or bind by name) to the interfaces of, the Work and
Derivative Works thereof.

"Contribution" shall mean any work of authorship, including the original
version of the Work and any modifications or additions to that Work or
Derivative Works thereof, that is intentionally submitted to Licensor for
inclusion in the Work by the copyright owner or by an individual or Legal
Entity authorized to submit on behalf of the copyright owner. For the
purposes of this definition, "submitted" means any form of electronic,
verbal, or written communication sent to the Licensor or its representatives,
including but not limited to communication on electronic mailing lists,
source code control systems, and issue tracking systems that are managed

"Contributor" shall mean Licensor and any individual or Legal Entity on
behalf of whom a Contribution has been received by Licensor and subsequently
incorporated within the Work.

2. Grant of Copyright License.

Subject to the terms and conditions of this License, each Contributor hereby
grants to You 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 the Work and
such Derivative Works in Source or Object form.

3. Grant of Patent License.

Subject to the terms and conditions of this License, each Contributor hereby
grants to You 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 such
Contributor that are necessarily infringed by their Contribution(s) alone
or by combination of their Contribution(s) with the Work to which such
Contribution(s) was submitted. If You institute patent litigation against
any entity (including a cross-claim or counterclaim in a lawsuit) alleging
that the Work or a Contribution incorporated within the Work constitutes
direct or contributory patent infringement, then any patent licenses granted
to You under this License for that Work shall terminate as of the date such
litigation is filed.

4. Redistribution.

You may reproduce and distribute copies of the Work or Derivative Works
thereof in any medium, with or without modifications, and in Source or Object
form, provided that You meet the following conditions:

(a) You must give any other recipients of the Work or Derivative Works a
    copy of this License; and

(b) You must cause any modified files to carry prominent notices stating
    that You changed the files; and

(c) You must retain, in the Source form of any Derivative Works that You
    distribute, all copyright, patent, trademark, and attribution notices
    from the Source form of the Work, excluding those notices that do not
    pertain to any part of the Derivative Works; and

(d) If the Work includes a "NOTICE" text file as part of its distribution,
    then any Derivative Works that You distribute must include a readable
    copy of the attribution notices contained within such NOTICE file,
    excluding those notices that do not pertain to any part of the Derivative
    Works, in at least one of the following places: within a NOTICE text
    file distributed as part of the Derivative Works; within the Source form
    or documentation, if provided along with the Derivative Works; or,
    within a display generated by the Derivative Works, if and wherever such
    third-party notices normally appear. The contents of the NOTICE file are
    for informational purposes only and do not modify the License. You may
    add Your own attribution notices within Derivative Works that You
    distribute, alongside or as an addendum to the NOTICE text from the Work,
    provided that such additional attribution notices cannot be construed
    as modifying the License.

You may add Your own copyright statement to Your modifications and may
provide additional or different license terms and conditions for use,
reproduction, or distribution of Your modifications, or for any such
Derivative Works as a whole, provided Your use, reproduction, and
distribution of the Work otherwise complies with the conditions stated in
this License.

5. Submission of Contributions.

Unless You explicitly state otherwise, any Contribution intentionally
submitted for inclusion in the Work by You to the Licensor shall be under
the terms and conditions of this License, without any additional terms or
conditions. Notwithstanding the above, nothing herein shall supersede or
modify the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.

6. Trademarks.

This License does not grant permission to use the trade names, trademarks,
service marks, or product names of the Licensor, except as required for
reasonable and customary use in describing the origin of the Work and
reproducing the content of the NOTICE file.

7. Disclaimer of Warranty.

Unless required by applicable law or agreed to in writing, Licensor provides
the Work (and each Contributor provides its 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. You are solely responsible for determining the appropriateness of
using or redistributing the Work and assume any risks associated with Your
exercise of permissions under this License.

8. Limitation of Liability.

In no event and under no legal theory, whether in tort (including negligence),
contract, or otherwise, unless required by applicable law (such as deliberate
and grossly negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special, incidental,
or consequential damages of any character arising as a result of this License
or out of the use or inability to use the Work (including but not limited to
damages for loss of goodwill, work stoppage, computer failure or malfunction,
or any and all other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.

9. Accepting Warranty or Additional Liability.

While redistributing the Work or Derivative Works thereof, You may choose to
offer, and charge a fee for, acceptance of support, warranty, indemnity, or
other liability obligations and/or rights consistent with this License.
However, in accepting such obligations, You may act only on Your own behalf
and on Your sole responsibility, not on behalf of any other Contributor,
and only if You agree to indemnify, defend, and hold each Contributor harmless
for any liability incurred by, or claims asserted against, such Contributor
by reason of your accepting any such warranty or additional liability.
