+#    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.
+#

+#       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
