TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
 
 
 
 
1. Definitions.

   "Source" form shall mean the preferred form for making modifications,
 
   including but not limited to software source code, documentation
 
   source, and configuration files.
 
 
 
 
   "Object" form shall mean any form resulting from mechanical
 
   transformation or translation of a Source form, including but
 
   not limited to compiled object code, generated documentation,
 
   and conversions to other media types.
 
 
 
 
   "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, as a whole, an original work of authorship. For the purposes
 
   of this 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 by, or on behalf of, the
 
   Licensor for the purpose of discussing and improving the Work, but
 
   excluding communication that is conspicuously marked or otherwise
 
   designated in writing by the copyright owner as "Not a Contribution."
 
 
 
 
   "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.
