      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.

Any Covered Software that You distribute or otherwise make available in Executable form must also be made available in Source Code form and that Source Code form must be distributed only under the terms of this License. You must include a copy of this License with every copy of the Source Code form of the Covered Software You distribute or otherwise make available. You must inform recipients of any such Covered Software in Executable form as to how they can obtain such Covered Software in Source Code form in a reasonable manner on or through a medium customarily used for software exchange.

You must include a notice in each of Your Modifications that identifies You as the Contributor of the Modification. You may not remove or alter any copyright, patent or trademark notices contained within the Covered Software, or any notices of licensing or any descriptive text giving attribution to any Contributor or the Initial Developer.

3.4. Application of Additional Terms.
You may not offer or impose any terms on any Covered Software in Source Code form that alters or restricts the applicable version of this License or the recipients rights hereunder. You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations to one or more recipients of Covered Software. However, you may do so only on Your own behalf, and not on behalf of the Initial Developer or any Contributor. You must make it absolutely clear that any such warranty, support, indemnity or liability obligation is offered by You alone, and You hereby agree to indemnify the Initial Developer and every Contributor for any liability incurred by the Initial Developer or such Contributor as a result of warranty, support, indemnity or liability terms You offer.

3.5. Distribution of Executable Versions.
You may distribute the Executable form of the Covered Software under the terms of this License or under the terms of a license of Your choice, which may contain terms different from this License, provided that You are in compliance with the terms of this License and that the license for the Executable form does not attempt to limit or alter the recipients rights in the Source Code form from the rights set forth in this License. If You distribute the Covered Software in Executable form under a different license, You must make it absolutely clear that any terms which differ from this License are offered by You alone, not by the Initial Developer or Contributor.

4.2. Effect of New Versions.

You may always continue to use, distribute or otherwise make the Covered Software available under the terms of the version of the License under which You originally received the Covered Software. If the Initial Developer includes a notice in the Original Software prohibiting it from being distributed or otherwise made available under any subsequent version of the License, You must distribute and make the Covered Software available under the terms of the version of the License under which You originally received the Covered Software. Otherwise, You may also choose to use, distribute or otherwise make the Covered Software available under the terms of any subsequent version of the License published by the license steward.
4.3. Modified Versions.

When You are an Initial Developer and You want to create a new license for Your Original Software, You may create and use a modified version of this License if You: (a) rename the license and remove any references to the name of the license steward (except to note that the license differs from this License); and (b) otherwise make it clear that the license contains terms which differ from this License.

5. DISCLAIMER OF WARRANTY.

COVERED SOFTWARE IS PROVIDED UNDER THIS LICENSE ON AN AS IS BASIS, WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT THE COVERED SOFTWARE IS FREE OF DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED SOFTWARE IS WITH YOU. SHOULD ANY COVERED SOFTWARE PROVE DEFECTIVE IN ANY RESPECT, YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF ANY COVERED SOFTWARE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.

6. TERMINATION.

6.1. This License and the rights granted hereunder will terminate automatically if You fail to comply with terms herein and fail to cure such breach within 30 days of becoming aware of the breach. Provisions which, by their nature, must remain in effect beyond the termination of this License shall survive.

6.2. If You assert a patent infringement claim (excluding declaratory judgment actions) against Initial Developer or a Contributor (the Initial Developer or Contributor against whom You assert such claim is referred to as Participant) alleging that the Participant Software (meaning the Contributor Version where the Participant is a Contributor or the Original Software where the Participant is the Initial Developer) directly or indirectly infringes any patent, then any and all rights granted directly or indirectly to You by such Participant, the Initial Developer (if the Initial Developer is not the Participant) and all Contributors under Sections 2.1 and/or 2.2 of this License shall, upon 60 days notice from Participant terminate prospectively and automatically at the expiration of such 60 day notice period, unless if within such 60 day period You withdraw Your claim with respect to the Participant Software against such Participant either unilaterally or pursuant to a written agreement with Participant.

6.3. In the event of termination under Sections 6.1 or 6.2 above, all end user licenses that have been validly granted by You or any distributor hereunder prior to termination (excluding licenses granted to You by any distributor) shall survive termination.

7. LIMITATION OF LIABILITY.

UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED SOFTWARE, OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOST PROFITS, LOSS OF GOODWILL, WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY RESULTING FROM SUCH PARTYS NEGLIGENCE TO THE EXTENT APPLICABLE LAW PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.

8. U.S. GOVERNMENT END USERS.

The Covered Software is a commercial item, as that term is defined in 48 C.F.R. 2.101 (Oct. 1995), consisting of commercial computer software (as that term is defined at 48 C.F.R.  252.227-7014(a)(1)) and commercial computer software documentation as such terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48 C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995), all U.S. Government End Users acquire Covered Software with only those rights set forth herein. This U.S. Government Rights clause is in lieu of, and supersedes, any other FAR, DFAR, or other clause or provision that addresses Government rights in computer software under this License.

9. MISCELLANEOUS.

This License represents the complete agreement concerning subject matter hereof. If any provision of this License is held to be unenforceable, such provision shall be reformed only to the extent necessary to make it enforceable. This License shall be governed by the law of the jurisdiction specified in a notice contained within the Original Software (except to the extent applicable law, if any, provides otherwise), excluding such jurisdictions conflict-of-law provisions. Any litigation relating to this License shall be subject to the jurisdiction of the courts located in the jurisdiction and venue specified in a notice contained within the Original Software, with the losing party responsible for costs, including, without limitation, court costs and reasonable attorneys fees and expenses. The application of the United Nations Convention on Contracts for the International Sale of Goods is expressly excluded. Any law or regulation which provides that the language of a contract shall be construed against the drafter shall not apply to this License. You agree that You alone are responsible for compliance with the United States export administration regulations (and the export control laws and regulation of any other countries) when You use, distribute or otherwise make available any Covered Software.

10. RESPONSIBILITY FOR CLAIMS.

As between Initial Developer and the Contributors, each party is responsible for claims and damages arising, directly or indirectly, out of its utilization of rights under this License and You agree to work with Initial Developer and Contributors to distribute such responsibility on an equitable basis. Nothing herein is intended or shall be deemed to constitute any admission of liability.

    Source Code form in a reasonable manner on or through a medium 
    customarily used for software exchange. 

    3.2. Modifications. 

    The Modifications that You create or to which You contribute are 
    governed by the terms of this License. You represent that You believe 
    Your Modifications are Your original creation(s) and/or You have 
    sufficient rights to grant the rights conveyed by this License. 

    3.3. Required Notices. 

    You must include a notice in each of Your Modifications that identifies 
    You as the Contributor of the Modification. You may not remove or alter 
    any copyright, patent or trademark notices contained within the Covered 
    Software, or any notices of licensing or any descriptive text giving 
    attribution to any Contributor or the Initial Developer. 

    3.4. Application of Additional Terms. 

    You may not offer or impose any terms on any Covered Software in Source 
    Code form that alters or restricts the applicable version of this 
    License or the recipients' rights hereunder. You may choose to offer, 
    and to charge a fee for, warranty, support, indemnity or liability 
    obligations to one or more recipients of Covered Software. However, you 
    may do so only on Your own behalf, and not on behalf of the Initial 
    Developer or any Contributor. You must make it absolutely clear that any 
    such warranty, support, indemnity or liability obligation is offered by 
    You alone, and You hereby agree to indemnify the Initial Developer and 
    every Contributor for any liability incurred by the Initial Developer or 
    such Contributor as a result of warranty, support, indemnity or 
    liability terms You offer. 

    3.5. Distribution of Executable Versions. 

    You may distribute the Executable form of the Covered Software under the 
    terms of this License or under the terms of a license of Your choice, 
    which may contain terms different from this License, provided that You 
    are in compliance with the terms of this License and that the license 
    for the Executable form does not attempt to limit or alter the 
    recipient's rights in the Source Code form from the rights set forth in 
    this License. If You distribute the Covered Software in Executable form 
    under a different license, You must make it absolutely clear that any 
    terms which differ from this License are offered by You alone, not by 
    the Initial Developer or Contributor. You hereby agree to indemnify the 
    Initial Developer and every Contributor for any liability incurred by 
    the Initial Developer or such Contributor as a result of any such terms 
    You offer. 

    3.6. Larger Works. 

    You may create a Larger Work by combining Covered Software with other 
    code not governed by the terms of this License and distribute the Larger 
    Work as a single product. In such a case, You must make sure the 
    requirements of this License are fulfilled for the Covered Software. 

4. Versions of the License. 

    4.1. New Versions. 

    Oracle is the initial license steward and may publish revised and/or new 
    versions of this License from time to time. Each version will be given a 
    distinguishing version number. Except as provided in Section 4.3, no one 
    other than the license steward has the right to modify this License. 

    4.2. Effect of New Versions. 

    You may always continue to use, distribute or otherwise make the Covered 
    Software available under the terms of the version of the License under 
    which You originally received the Covered Software. If the Initial 
    Developer includes a notice in the Original Software prohibiting it from 
    being distributed or otherwise made available under any subsequent 
    version of the License, You must distribute and make the Covered 
    Software available under the terms of the version of the License under 
    which You originally received the Covered Software. Otherwise, You may 
    also choose to use, distribute or otherwise make the Covered Software 
    available under the terms of any subsequent version of the License 
    published by the license steward. 

    4.3. Modified Versions. 

    When You are an Initial Developer and You want to create a new license 
    for Your Original Software, You may create and use a modified version of 
    this License if You: (a) rename the license and remove any references to 
    the name of the license steward (except to note that the license differs 
    from this License); and (b) otherwise make it clear that the license 
    contains terms which differ from this License. 

5. DISCLAIMER OF WARRANTY. 

    COVERED SOFTWARE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS, 
    WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, 
    WITHOUT LIMITATION, WARRANTIES THAT THE COVERED SOFTWARE IS FREE OF 
    DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING. 
    THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED 
    SOFTWARE IS WITH YOU. SHOULD ANY COVERED SOFTWARE PROVE DEFECTIVE IN ANY 
    RESPECT, YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME 
    THE COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS 
    DISCLAIMER OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO 
    USE OF ANY COVERED SOFTWARE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS 
    DISCLAIMER. 

6. TERMINATION. 

    6.1. This License and the rights granted hereunder will terminate 
    automatically if You fail to comply with terms herein and fail to cure 
    such breach within 30 days of becoming aware of the breach. Provisions 
    which, by their nature, must remain in effect beyond the termination of 
    this License shall survive. 

    6.2. If You assert a patent infringement claim (excluding declaratory 
    judgment actions) against Initial Developer or a Contributor (the 
    Initial Developer or Contributor against whom You assert such claim is 
    referred to as "Participant") alleging that the Participant Software 
    (meaning the Contributor Version where the Participant is a Contributor 
    or the Original Software where the Participant is the Initial Developer) 
    directly or indirectly infringes any patent, then any and all rights 
    granted directly or indirectly to You by such Participant, the Initial 
    Developer (if the Initial Developer is not the Participant) and all 
    Contributors under Sections 2.1 and/or 2.2 of this License shall, upon 
    60 days notice from Participant terminate prospectively and 
    automatically at the expiration of such 60 day notice period, unless if 
    within such 60 day period You withdraw Your claim with respect to the 
    Participant Software against such Participant either unilaterally or 
    pursuant to a written agreement with Participant. 

    6.3. If You assert a patent infringement claim against Participant 
    alleging that the Participant Software directly or indirectly infringes 
    any patent where such claim is resolved (such as by license or 
    settlement) prior to the initiation of patent infringement litigation, 
    then the reasonable value of the licenses granted by such Participant 
    under Sections 2.1 or 2.2 shall be taken into account in determining the 
    amount or value of any payment or license. 

    6.4. In the event of termination under Sections 6.1 or 6.2 above, all 
    end user licenses that have been validly granted by You or any 
    distributor hereunder prior to termination (excluding licenses granted 
    to You by any distributor) shall survive termination. 

7. LIMITATION OF LIABILITY. 

    UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT 
    (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL 
    DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED 
    SOFTWARE, OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY 
    PERSON FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES 
    OF ANY CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF 
    GOODWILL, WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL 
    OTHER COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN 
    INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF 
    LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY 
    RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW 
    PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION 
    OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS EXCLUSION 
    AND LIMITATION MAY NOT APPLY TO YOU. 

8. U.S. GOVERNMENT END USERS. 

    The Covered Software is a "commercial item," as that term is defined in 
    48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer 
    software" (as that term is defined at 48 C.F.R. § 252.227-7014(a)(1)) 
    and "commercial computer software documentation" as such terms are used 
    in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48 C.F.R. 12.212 and 
    48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995), all U.S. Government 
    End Users acquire Covered Software with only those rights set forth 
    herein. This U.S. Government Rights clause is in lieu of, and 
    supersedes, any other FAR, DFAR, or other clause or provision that 
    addresses Government rights in computer software under this License. 

9. MISCELLANEOUS. 

    This License represents the complete agreement concerning subject matter 
    hereof. If any provision of this License is held to be unenforceable, 
    such provision shall be reformed only to the extent necessary to make it 
    enforceable. This License shall be governed by the law of the 
    jurisdiction specified in a notice contained within the Original 
    Software (except to the extent applicable law, if any, provides 
    otherwise), excluding such jurisdiction's conflict-of-law provisions. 
    Any litigation relating to this License shall be subject to the 
    jurisdiction of the courts located in the jurisdiction and venue 
    specified in a notice contained within the Original Software, with the 
    losing party responsible for costs, including, without limitation, court 
    costs and reasonable attorneys' fees and expenses. The application of 
    the United Nations Convention on Contracts for the International Sale of 
    Goods is expressly excluded. Any law or regulation which provides that 
    the language of a contract shall be construed against the drafter shall 
    not apply to this License. You agree that You alone are responsible for 
    compliance with the United States export administration regulations (and 
    the export control laws and regulation of any other countries) when You 
    use, distribute or otherwise make available any Covered Software. 

10. RESPONSIBILITY FOR CLAIMS. 

    As between Initial Developer and the Contributors, each party is 
    responsible for claims and damages arising, directly or indirectly, out 
    of its utilization of rights under this License and You agree to work 
    with Initial Developer and Contributors to distribute such 
    responsibility on an equitable basis. Nothing herein is intended or 
    shall be deemed to constitute any admission of liability. 

NOTICE PURSUANT TO SECTION 9 OF THE COMMON DEVELOPMENT AND DISTRIBUTION 
LICENSE (CDDL) 

The code released under the CDDL shall be governed by the laws of the 
State of California (excluding conflict-of-law provisions). Any 
litigation relating to this License shall be subject to the jurisdiction 
of the Federal Courts of the Northern District of California and the 
state courts of the State of California, with venue lying in Santa Clara 
County, California. 




The GNU General Public License (GPL) Version 2, June 1991 

Copyright (C) 1989, 1991 Free Software Foundation, Inc. 59 Temple Place, 
Suite 330, Boston, MA 02111-1307 USA 

Everyone is permitted to copy and distribute verbatim copies of this 
license document, but changing it is not allowed. 

Preamble 

The licenses for most software are designed to take away your freedom to 
share and change it. By contrast, the GNU General Public License is 
intended to guarantee your freedom to share and change free software--to 
make sure the software is free for all its users. This General Public 
License applies to most of the Free Software Foundation's software and 
to any other program whose authors commit to using it. (Some other Free 
Software Foundation software is covered by the GNU Library General 
Public License instead.) You can apply it to your programs, too. 

When we speak of free software, we are referring to freedom, not price. 
Our General Public Licenses are designed to make sure that you have the 
freedom to distribute copies of free software (and charge for this 
service if you wish), that you receive source code or can get it if you 
want it, that you can change the software or use pieces of it in new 
free programs; and that you know you can do these things. 

To protect your rights, we need to make restrictions that forbid anyone 
to deny you these rights or to ask you to surrender the rights. These 
restrictions translate to certain responsibilities for you if you 
distribute copies of the software, or if you modify it. 

For example, if you distribute copies of such a program, whether gratis 
or for a fee, you must give the recipients all the rights that you have. 
You must make sure that they, too, receive or can get the source code. 
And you must show them these terms so they know their rights. 

We protect your rights with two steps: (1) copyright the software, and 
(2) offer you this license which gives you legal permission to copy, 
distribute and/or modify the software. 

Also, for each author's protection and ours, we want to make certain 
that everyone understands that there is no warranty for this free 
software. If the software is modified by someone else and passed on, we 
want its recipients to know that what they have is not the original, so 
that any problems introduced by others will not reflect on the original 
authors' reputations. 

Finally, any free program is threatened constantly by software patents. 
We wish to avoid the danger that redistributors of a free program will 
individually obtain patent licenses, in effect making the program 
proprietary. To prevent this, we have made it clear that any patent must 
be licensed for everyone's free use or not licensed at all. 

The precise terms and conditions for copying, distribution and 
modification follow. 

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 

0. This License applies to any program or other work which contains a 
notice placed by the copyright holder saying it may be distributed under 
the terms of this General Public License. The "Program", below, refers 
to any such program or work, and a "work based on the Program" means 
either the Program or any derivative work under copyright law: that is 
to say, a work containing the Program or a portion of it, either 
verbatim or with modifications and/or translated into another language. 
(Hereinafter, translation is included without limitation in the term 
"modification".) Each licensee is addressed as "you". 

Activities other than copying, distribution and modification are not 
covered by this License; they are outside its scope. The act of running 
the Program is not restricted, and the output from the Program is 
covered only if its contents constitute a work based on the Program 
(independent of having been made by running the Program). Whether that 
is true depends on what the Program does. 

1. You may copy and distribute verbatim copies of the Program's source 
code as you receive it, in any medium, provided that you conspicuously 
and appropriately publish on each copy an appropriate copyright notice 
and disclaimer of warranty; keep intact all the notices that refer to 
this License and to the absence of any warranty; and give any other 
recipients of the Program a copy of this License along with the Program. 

You may charge a fee for the physical act of transferring a copy, and 
you may at your option offer warranty protection in exchange for a fee. 

2. You may modify your copy or copies of the Program or any portion of 
it, thus forming a work based on the Program, and copy and distribute 
such modifications or work under the terms of Section 1 above, provided 
that you also meet all of these conditions: 

    a) You must cause the modified files to carry prominent notices stating 
    that you changed the files and the date of any change. 

    b) You must cause any work that you distribute or publish, that in whole 
    or in part contains or is derived from the Program or any part thereof, 
    to be licensed as a whole at no charge to all third parties under the 
    terms of this License. 

    c) If the modified program normally reads commands interactively when 
    run, you must cause it, when started running for such interactive use in 
    the most ordinary way, to print or display an announcement including an 
    appropriate copyright notice and a notice that there is no warranty (or 
    else, saying that you provide a warranty) and that users may 
    redistribute the program under these conditions, and telling the user 
    how to view a copy of this License. (Exception: if the Program itself is 
    interactive but does not normally print such an announcement, your work 
    based on the Program is not required to print an announcement.) 

These requirements apply to the modified work as a whole. If 
identifiable sections of that work are not derived from the Program, and 
can be reasonably considered independent and separate works in 
themselves, then this License, and its terms, do not apply to those 
sections when you distribute them as separate works. But when you 
distribute the same sections as part of a whole which is a work based on 
the Program, the distribution of the whole must be on the terms of this 
License, whose permissions for other licensees extend to the entire 
whole, and thus to each and every part regardless of who wrote it. 

Thus, it is not the intent of this section to claim rights or contest 
your rights to work written entirely by you; rather, the intent is to 
exercise the right to control the distribution of derivative or 
collective works based on the Program. 

In addition, mere aggregation of another work not based on the Program 
with the Program (or with a work based on the Program) on a volume of a 
storage or distribution medium does not bring the other work under the 
scope of this License. 

3. You may copy and distribute the Program (or a work based on it, under 
Section 2) in object code or executable form under the terms of Sections 
1 and 2 above provided that you also do one of the following: 

    a) Accompany it with the complete corresponding machine-readable source 
    code, which must be distributed under the terms of Sections 1 and 2 
    above on a medium customarily used for software interchange; or, 

    b) Accompany it with a written offer, valid for at least three years, to 
    give any third party, for a charge no more than your cost of physically 
    performing source distribution, a complete machine-readable copy of the 
    corresponding source code, to be distributed under the terms of Sections 
    1 and 2 above on a medium customarily used for software interchange; or, 

    c) Accompany it with the information you received as to the offer to 
    distribute corresponding source code. (This alternative is allowed only 
    for noncommercial distribution and only if you received the program in 
    object code or executable form with such an offer, in accord with 
    Subsection b above.) 

The source code for a work means the preferred form of the work for 
making modifications to it. For an executable work, complete source code 
means all the source code for all modules it contains, plus any 
associated interface definition files, plus the scripts used to control 
compilation and installation of the executable. However, as a special 
exception, the source code distributed need not include anything that is 
normally distributed (in either source or binary form) with the major 
components (compiler, kernel, and so on) of the operating system on 
which the executable runs, unless that component itself accompanies the 
executable. 

If distribution of executable or object code is made by offering access 
to copy from a designated place, then offering equivalent access to copy 
the source code from the same place counts as distribution of the source 
code, even though third parties are not compelled to copy the source 
along with the object code. 

4. You may not copy, modify, sublicense, or distribute the Program 
except as expressly provided under this License. Any attempt otherwise 
to copy, modify, sublicense or distribute the Program is void, and will 
automatically terminate your rights under this License. However, parties 
who have received copies, or rights, from you under this License will 
not have their licenses terminated so long as such parties remain in 
full compliance. 

5. You are not required to accept this License, since you have not 
signed it. However, nothing else grants you permission to modify or 
distribute the Program or its derivative works. These actions are 
prohibited by law if you do not accept this License. Therefore, by 
modifying or distributing the Program (or any work based on the 
Program), you indicate your acceptance of this License to do so, and all 
its terms and conditions for copying, distributing or modifying the 
Program or works based on it. 

6. Each time you redistribute the Program (or any work based on the 
Program), the recipient automatically receives a license from the 
original licensor to copy, distribute or modify the Program subject to 
these terms and conditions. You may not impose any further restrictions 
on the recipients' exercise of the rights granted herein. You are not 
responsible for enforcing compliance by third parties to this License. 

7. If, as a consequence of a court judgment or allegation of patent 
infringement or for any other reason (not limited to patent issues), 
conditions are imposed on you (whether by court order, agreement or 
otherwise) that contradict the conditions of this License, they do not 
excuse you from the conditions of this License. If you cannot distribute 
so as to satisfy simultaneously your obligations under this License and 
any other pertinent obligations, then as a consequence you may not 
distribute the Program at all. For example, if a patent license would 
not permit royalty-free redistribution of the Program by all those who 
receive copies directly or indirectly through you, then the only way you 
could satisfy both it and this License would be to refrain entirely from 
distribution of the Program. 

If any portion of this section is held invalid or unenforceable under 
any particular circumstance, the balance of the section is intended to 
apply and the section as a whole is intended to apply in other 
circumstances. 

It is not the purpose of this section to induce you to infringe any 
patents or other property right claims or to contest validity of any 
such claims; this section has the sole purpose of protecting the 
integrity of the free software distribution system, which is implemented 
by public license practices. Many people have made generous 
contributions to the wide range of software distributed through that 
system in reliance on consistent application of that system; it is up to 
the author/donor to decide if he or she is willing to distribute 
software through any other system and a licensee cannot impose that 
choice. 

This section is intended to make thoroughly clear what is believed to be 
a consequence of the rest of this License. 

8. If the distribution and/or use of the Program is restricted in 
certain countries either by patents or by copyrighted interfaces, the 
original copyright holder who places the Program under this License may 
add an explicit geographical distribution limitation excluding those 
countries, so that distribution is permitted only in or among countries 
not thus excluded. In such case, this License incorporates the 
limitation as if written in the body of this License. 

9. The Free Software Foundation may publish revised and/or new versions 
of the General Public License from time to time. Such new versions will 
be similar in spirit to the present version, but may differ in detail to 
address new problems or concerns. 

Each version is given a distinguishing version number. If the Program 
specifies a version number of this License which applies to it and "any 
later version", you have the option of following the terms and 
conditions either of that version or of any later version published by 
the Free Software Foundation. If the Program does not specify a version 
number of this License, you may choose any version ever published by the 
Free Software Foundation. 

10. If you wish to incorporate parts of the Program into other free 
programs whose distribution conditions are different, write to the 
author to ask for permission. For software which is copyrighted by the 
Free Software Foundation, write to the Free Software Foundation; we 
sometimes make exceptions for this. Our decision will be guided by the 
two goals of preserving the free status of all derivatives of our free 
software and of promoting the sharing and reuse of software generally. 

NO WARRANTY 

11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER 
EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED 
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE 
ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH 
YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL 
NECESSARY SERVICING, REPAIR OR CORRECTION. 

12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN 
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY 
AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR 
DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL 
DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM 
(INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED 
INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF 
THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR 
OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 

END OF TERMS AND CONDITIONS 

How to Apply These Terms to Your New Programs 

If you develop a new program, and you want it to be of the greatest 
possible use to the public, the best way to achieve this is to make it 
free software which everyone can redistribute and change under these 
terms. 

To do so, attach the following notices to the program. It is safest to 
attach them to the start of each source file to most effectively convey 
the exclusion of warranty; and each file should have at least the 
"copyright" line and a pointer to where the full notice is found. 

    One line to give the program's name and a brief idea of what it does. 
    Copyright (C) <year> <name of author> 

    This program is free software; you can redistribute it and/or modify it 
    under the terms of the GNU General Public License as published by the 
    Free Software Foundation; either version 2 of the License, or (at your 
    option) any later version. 

    This program is distributed in the hope that it will be useful, but 
    WITHOUT ANY WARRANTY; without even the implied warranty of 
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General 
    Public License for more details. 

    You should have received a copy of the GNU General Public License along 
    with this program; if not, write to the Free Software Foundation, Inc., 
    59 Temple Place, Suite 330, Boston, MA 02111-1307 USA 

Also add information on how to contact you by electronic and paper mail. 

If the program is interactive, make it output a short notice like this 
when it starts in an interactive mode: 

    Gnomovision version 69, Copyright (C) year name of author Gnomovision 
    comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is 
    free software, and you are welcome to redistribute it under certain 
    conditions; type `show c' for details. 

The hypothetical commands `show w' and `show c' should show the 
appropriate parts of the General Public License. Of course, the commands 
you use may be called something other than `show w' and `show c'; they 
could even be mouse-clicks or menu items--whatever suits your program. 

You should also get your employer (if you work as a programmer) or your 
school, if any, to sign a "copyright disclaimer" for the program, if 
necessary. Here is a sample; alter the names: 

    Yoyodyne, Inc., hereby disclaims all copyright interest in the program 
    `Gnomovision' (which makes passes at compilers) written by James Hacker. 

    signature of Ty Coon, 1 April 1989
    Ty Coon, President of Vice 

This General Public License does not permit incorporating your program 
into proprietary programs. If your program is a subroutine library, you 
may consider it more useful to permit linking proprietary applications 
with the library. If this is what you want to do, use the GNU Library 
General Public License instead of this License.

"CLASSPATH" EXCEPTION TO THE GPL VERSION 2 

Certain source files distributed by Oracle are subject to the following 
clarification and special exception to the GPL Version 2, but only where 
Oracle has expressly included in the particular source file's header the 
words "Oracle designates this particular file as subject to the 
"Classpath" exception as provided by Oracle in the License file that 
accompanied this code." 

Linking this library statically or dynamically with other modules is 
making a combined work based on this library. Thus, the terms and 
conditions of the GNU General Public License Version 2 cover the whole 
combination. 

As a special exception, the copyright holders of this library give you 
permission to link this library with independent modules to produce an 
executable, regardless of the license terms of these independent 
modules, and to copy and distribute the resulting executable under terms 
of your choice, provided that you also meet, for each linked independent 
module, the terms and conditions of the license of that module. An 
independent module is a module which is not derived from or based on 
this library. If you modify this library, you may extend this exception 
to your version of the library, but you are not obligated to do so. If 
you do not wish to do so, delete this exception statement from your 
version.

LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION OF THE PROGRAM
CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.

1. DEFINITIONS

"Contribution" means:

      a) in the case of the initial Contributor, the initial code and
         documentation distributed under this Agreement, and
      b) in the case of each subsequent Contributor:

      i) changes to the Program, and

      ii) additions to the Program;

      where such changes and/or additions to the Program originate from and are
distributed by that particular Contributor. A Contribution 'originates' from a
Contributor if it was added to the Program by such Contributor itself or anyone
acting on such Contributor's behalf. Contributions do not include additions to
the Program which: (i) are separate modules of software distributed in
conjunction with the Program under their own license agreement, and (ii) are
not derivative works of the Program. 

"Contributor" means any person or entity that distributes the Program.

"Licensed Patents " mean patent claims licensable by a Contributor which are
necessarily infringed by the use or sale of its Contribution alone or when
combined with the Program.

"Program" means the Contributions distributed in accordance with this Agreement.

"Recipient" means anyone who receives the Program under this Agreement,
including all Contributors.

2. GRANT OF RIGHTS

      a) Subject to the terms of this Agreement, each Contributor hereby grants
Recipient a non-exclusive, worldwide, royalty-free copyright license to
reproduce, prepare derivative works of, publicly display, publicly perform,
distribute and sublicense the Contribution of such Contributor, if any, and
such derivative works, in source code and object code form.

      b) Subject to the terms of this Agreement, each Contributor hereby grants
Recipient a non-exclusive, worldwide, royalty-free patent license under
Licensed Patents to make, use, sell, offer to sell, import and otherwise
transfer the Contribution of such Contributor, if any, in source code and
object code form. This patent license shall apply to the combination of the
Contribution and the Program if, at the time the Contribution is added by the
Contributor, such addition of the Contribution causes such combination to be
covered by the Licensed Patents. The patent license shall not apply to any
other combinations which include the Contribution. No hardware per se is
licensed hereunder. 

      c) Recipient understands that although each Contributor grants the
licenses to its Contributions set forth herein, no assurances are provided by
any Contributor that the Program does not infringe the patent or other
intellectual property rights of any other entity. Each Contributor disclaims
any liability to Recipient for claims brought by any other entity based on
infringement of intellectual property rights or otherwise. As a condition to
exercising the rights and licenses granted hereunder, each Recipient hereby
assumes sole responsibility to secure any other intellectual property rights
needed, if any. For example, if a third party patent license is required to
allow Recipient to distribute the Program, it is Recipient's responsibility to
acquire that license before distributing the Program.

      d) Each Contributor represents that to its knowledge it has sufficient
copyright rights in its Contribution, if any, to grant the copyright license
set forth in this Agreement. 

3. REQUIREMENTS

A Contributor may choose to distribute the Program in object code form under
its own license agreement, provided that:

      a) it complies with the terms and conditions of this Agreement; and

      b) its license agreement:

      i) effectively disclaims on behalf of all Contributors all warranties and
conditions, express and implied, including warranties or conditions of title
and non-infringement, and implied warranties or conditions of merchantability
and fitness for a particular purpose; 

      ii) effectively excludes on behalf of all Contributors all liability for
damages, including direct, indirect, special, incidental and consequential
damages, such as lost profits; 

      iii) states that any provisions which differ from this Agreement are
offered by that Contributor alone and not by any other party; and

      iv) states that source code for the Program is available from such
Contributor, and informs licensees how to obtain it in a reasonable manner on
or through a medium customarily used for software exchange. 

When the Program is made available in source code form:

      a) it must be made available under this Agreement; and 

      b) a copy of this Agreement must be included with each copy of the
Program. 

Contributors may not remove or alter any copyright notices contained within the
Program.

Each Contributor must identify itself as the originator of its Contribution, if
any, in a manner that reasonably allows subsequent Recipients to identify the
originator of the Contribution.

4. COMMERCIAL DISTRIBUTION

Commercial distributors of software may accept certain responsibilities with
respect to end users, business partners and the like. While this license is
intended to facilitate the commercial use of the Program, the Contributor who
includes the Program in a commercial product offering should do so in a manner
which does not create potential liability for other Contributors. Therefore, if
a Contributor includes the Program in a commercial product offering, such
Contributor ("Commercial Contributor") hereby agrees to defend and indemnify
every other Contributor ("Indemnified Contributor") against any losses, damages
and costs (collectively "Losses") arising from claims, lawsuits and other legal
actions brought by a third party against the Indemnified Contributor to the
extent caused by the acts or omissions of such Commercial Contributor in
connection with its distribution of the Program in a commercial product
offering. The obligations in this section do not apply to any claims or Losses
relating to any actual or alleged intellectual property infringement. In order
to qualify, an Indemnified Contributor must: a) promptly notify the Commercial
Contributor in writing of such claim, and b) allow the Commercial Contributor
to control, and cooperate with the Commercial Contributor in, the defense and
any related settlement negotiations. The Indemnified Contributor may
participate in any such claim at its own expense.

For example, a Contributor might include the Program in a commercial product
offering, Product X. That Contributor is then a Commercial Contributor. If that
Commercial Contributor then makes performance claims, or offers warranties
related to Product X, those performance claims and warranties are such
Commercial Contributor's responsibility alone. Under this section, the
Commercial Contributor would have to defend claims against the other
Contributors related to those performance claims and warranties, and if a court
requires any other Contributor to pay any damages as a result, the Commercial
Contributor must pay those damages.

5. NO WARRANTY

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED 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. Each
Recipient is solely responsible for determining the appropriateness of using
and distributing the Program and assumes all risks associated with its exercise
of rights under this Agreement, including but not limited to the risks and
costs of program errors, compliance with applicable laws, damage to or loss of
data, programs or equipment, and unavailability or interruption of operations.

6. DISCLAIMER OF LIABILITY

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR ANY
CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL,
SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST
PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT,
STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY
WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS
GRANTED HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

7. GENERAL

If any provision of this Agreement is invalid or unenforceable under applicable
law, it shall not affect the validity or enforceability of the remainder of the
terms of this Agreement, and without further action by the parties hereto, such
provision shall be reformed to the minimum extent necessary to make such
provision valid and enforceable.

If Recipient institutes patent litigation against a Contributor with respect to
a patent applicable to software (including a cross-claim or counterclaim in a
lawsuit), then any patent licenses granted by that Contributor to such
Recipient under this Agreement shall terminate as of the date such litigation
is filed. In addition, if Recipient institutes patent litigation against any
entity (including a cross-claim or counterclaim in a lawsuit) alleging that the
Program itself (excluding combinations of the Program with other software or
hardware) infringes such Recipient's patent(s), then such Recipient's rights
granted under Section 2(b) shall terminate as of the date such litigation is
filed.

All Recipient's rights under this Agreement shall terminate if it fails to
comply with any of the material terms or conditions of this Agreement and does
not cure such failure in a reasonable period of time after becoming aware of
such noncompliance. If all Recipient's rights under this Agreement terminate,
Recipient agrees to cease use and distribution of the Program as soon as
reasonably practicable. However, Recipient's obligations under this Agreement
and any licenses granted by Recipient relating to the Program shall continue
and survive.

Everyone is permitted to copy and distribute copies of this Agreement, but in
order to avoid inconsistency the Agreement is copyrighted and may only be
modified in the following manner. The Agreement Steward reserves the right to
publish new versions (including revisions) of this Agreement from time to time.
No one other than the Agreement Steward has the right to modify this Agreement.
IBM is the initial Agreement Steward. IBM may assign the responsibility to
serve as the Agreement Steward to a suitable separate entity. Each new version
of the Agreement will be given a distinguishing version number. The Program
(including Contributions) may always be distributed subject to the version of
the Agreement under which it was received. In addition, after a new version of
the Agreement is published, Contributor may elect to distribute the Program
(including its Contributions) under the new version. Except as expressly stated
in Sections 2(a) and 2(b) above, Recipient receives no rights or licenses to
the intellectual property of any Contributor under this Agreement, whether
expressly, by implication, estoppel or otherwise. All rights in the Program not
expressly granted under this Agreement are reserved.

This Agreement is governed by the laws of the State of New York and the
intellectual property laws of the United States of America. No party to this
Agreement will bring a legal action under this Agreement more than one year
after the cause of action arose. Each party waives its rights to a jury trial
in any resulting litigation.

# Project Management Committee Documentation

This outlines the steps for a PMC member to create a new release. More details
and policy guidelines can be found here: http://www.apache.org/dev/release-distribution

## Release Procedure

1. Generate code signing key if you do not already have one for Apache. Refer to
http://apache.org/dev/openpgp.html#generate-key on how to generate a strong code
signing key.
2. Add your public key to the `KEYS` file at the root of the source code tree.
3. Create a new release branch, with version bumped to the next release version.
    * `git checkout -b release/0.15.0`
    * Replace all `0.15.0-SNAPSHOT` in the code tree to `0.15.0`
    * `git commit -am "Prepare 0.15.0-rc1"`
    * `git tag -am "Apache PredictionIO 0.15.0-rc1" v0.15.0-rc1`
4. Push the release branch and tag to the apache git repo.
5. Wait for Travis to pass build on the release branch.
6. Package a clean tarball for staging a release candidate.
    * `git archive --format tar v0.15.0-rc1 >
  ../apache-predictionio-0.15.0-rc1.tar`
    * `cd ..; gzip apache-predictionio-0.15.0-rc1.tar`
7. Generate detached signature for the release candidate.
(http://apache.org/dev/release-signing.html#openpgp-ascii-detach-sig)
    * `gpg --armor --output apache-predictionio-0.15.0-rc1.tar.gz.asc
  --detach-sig apache-predictionio-0.15.0-rc1.tar.gz`
8. Generate SHA512 checksums for the release candidate.
    * `gpg --print-md SHA512 apache-predictionio-0.15.0-rc1.tar.gz >
  apache-predictionio-0.15.0-rc1.tar.gz.sha512`
9. Run `./make-distribution.sh` and repeat steps 6 to 8 to create binary distribution release.
    * `mv PredictionIO-0.15.0.tar.gz apache-predictionio-0.15.0-bin.tar.gz`
    * `gpg --armor --output apache-predictionio-0.15.0-bin.tar.gz.asc
  --detach-sig apache-predictionio-0.15.0-bin.tar.gz`
    * `gpg --print-md SHA512 apache-predictionio-0.15.0-bin.tar.gz >
  apache-predictionio-0.15.0-bin.tar.gz.sha512`
10. If you have not done so, use SVN to checkout
https://dist.apache.org/repos/dist/dev/predictionio. This is the area
for staging release candidates for voting.
    * `svn co https://dist.apache.org/repos/dist/dev/predictionio`
11. Create a subdirectory at the SVN staging area. The area should have a `KEYS` file.
    * `mkdir apache-predictionio-0.15.0-rc1`
    * `cp apache-predictionio-0.15.0-* apache-predictionio-0.15.0-rc1`
12. If you have updated the `KEYS` file, also copy that to the staging area.
13. `svn commit -m "Apache PredictionIO 0.15.0-rc1"`
14. Set up credentials with Apache Nexus using the SBT Sonatype plugin. Put this
in `~/.sbt/1.0/sonatype.sbt`.

  ```
  publishTo := {
      val nexus = "https://repository.apache.org/"
      if (isSnapshot.value)
        Some("snapshots" at nexus + "content/repositories/snapshots")
      else
        Some("releases" at nexus + "service/local/staging/deploy/maven2")
  }

  credentials += Credentials("Sonatype Nexus Repository Manager", "repository.apache.org", "<YOUR APACHE LDAP USERNAME>", "<YOUR APACHE LDAP PASSWORD>")
  ```
15. Run `sbt/sbt +publishLocal` first and then run `sbt/sbt +publishSigned +storage/publishSigned`.
Close the staged repository on Apache Nexus.
16. Send out email for voting on PredictionIO dev mailing list.

  ```
  Subject: [VOTE] Apache PredictionIO 0.15.0 Release (RC1)

- [PIO-28](https://issues.apache.org/jira/browse/PIO-28): Code refactoring of the command line interface. It is now possible to
  develop new interfaces that perform the same functionalities provided by the
  CLI.
- [PIO-53](https://issues.apache.org/jira/browse/PIO-53): Integration tests can now be tied to every single Git commit, without
  the need to update the official test Docker image.
- The meta data and model data access object methods are now public and marked
  as Core Developer API.
