+                           Version 2.0, January 2004

+                        http://www.apache.org/licenses/

+

+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION

+

+   1. Definitions.

+

+      "License" shall mean the terms and conditions for use, reproduction,

+      and distribution as defined by Sections 1 through 9 of this document.

+

+      "Licensor" shall mean the copyright owner or entity authorized by

+      the copyright owner that is granting the License.

+

+      "Legal Entity" shall mean the union of the acting entity and all

+      other entities that control, are controlled by, or are under common

+      control with that entity. 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.

+

+      "You" (or "Your") shall mean an individual or Legal Entity

+      exercising permissions granted by this License.

+

+      "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.

+

+   END OF TERMS AND CONDITIONS

+

+   APPENDIX: How to apply the Apache License to your work.

+

+      To apply the Apache License to your work, attach the following

+      boilerplate notice, with the fields enclosed by brackets "[]"

+      replaced with your own identifying information. (Don't include

+      the brackets!)  The text should be enclosed in the appropriate

+      comment syntax for the file format. We also recommend that a

+      file or class name and description of purpose be included on the

+      same "printed page" as the copyright notice for easier

+      identification within third-party archives.
