Open Software License version 2.1

   This Open Software License (the "License") applies to any original work of
   authorship (the "Original Work") whose owner (the "Licensor") has placed the
   following notice immediately following the copyright notice for the Original
   Work:

Licensed under the Open Software License version 2.1

    1. Grant of Copyright License. Licensor hereby grants You a world-wide,
       royalty-free, non-exclusive, perpetual, sublicenseable license to do the
       following:
         1. to reproduce the Original Work in copies;
         2. to prepare derivative works ("Derivative Works") based upon the
            Original Work;
         3. to distribute copies of the Original Work and Derivative Works to
            the  public, with the proviso that copies of Original Work or
            Derivative Works that You distribute shall be licensed under the
            Open Software License;
         4. to perform the Original Work publicly; and
         5. to display the Original Work publicly
    2. Grant  of Patent License. Licensor hereby grants You a world-wide,
       royalty-free, non-exclusive, perpetual, sublicenseable license, under
       patent claims owned or controlled by the Licensor that are embodied in
       the Original Work as furnished by the Licensor, to make, use, sell and
       offer for sale the Original Work and Derivative Works.
    3. Grant  of  Source  Code License . The term "Source Code" means the
       preferred form of the Original Work for making modifications to it and
       all available documentation describing how to modify the Original Work.
       Licensor hereby agrees to provide a machine-readable copy of the Source
       Code of the Original Work along with each copy of the Original Work that
       Licensor  distributes. Licensor reserves the right to satisfy this
       obligation by placing a machine-readable copy of the Source Code in an
       information repository reasonably calculated to permit inexpensive and
       convenient access by You for as long as Licensor continues to distribute
       the Original Work, and by publishing the address of that information
       repository in a notice immediately following the copyright notice that
       applies to the Original Work.
    4. Exclusions From License Grant . Neither the names of Licensor, nor the
       names  of  any contributors to the Original Work, nor any of their
       trademarks or service marks, may be used to endorse or promote products
       derived from this Original Work without express prior written permission
       of the Licensor. Nothing in this License shall be deemed to grant any
       rights to trademarks, copyrights, patents, trade secrets or any other
       intellectual property of Licensor except as expressly stated herein. No
       patent  license  is  granted  to  make, use, sell or offer to sell
       embodiments of any patent claims other than the licensed claims defined
       in Section 2. No right is granted to the trademarks of Licensor even if
       such marks are included in the Original Work. Nothing in this License
       shall be interpreted to prohibit Licensor from licensing under different
       terms from this License any Original Work that Licensor otherwise would
       have a right to license.
    5. External Deployment . The term "External Deployment" means the use or
       distribution of the Original Work or Derivative Works in any way such
       that the Original Work or Derivative Works may be used by anyone other
       than You, whether the Original Work or Derivative Works are distributed
       to those persons or made available as an application intended for use
       over a computer network. As an express condition for the grants of
       license hereunder, You agree that any External Deployment by You of a
       Derivative Work shall be deemed a distribution and shall be licensed to
       all under the terms of this License, as prescribed in section 1(c)
       herein.
    6. Attribution  Rights  .  You must retain, in the Source Code of any
       Derivative Works that You create, all copyright, patent or trademark
       notices  from the Source Code of the Original Work, as well as any
       notices of licensing and any descriptive text identified therein as an
       "Attribution Notice." You must cause the Source Code for any Derivative
       Works that You create to carry a prominent Attribution Notice reasonably
       calculated to inform recipients that You have modified the Original
       Work.
    7. Warranty of Provenance and Disclaimer of Warranty . Licensor warrants
       that the copyright in and to the Original Work and the patent rights
       granted herein by Licensor are owned by the Licensor or are sublicensed
       to  You under the terms of this License with the permission of the
       contributor(s)  of  those  copyrights and patent rights. Except as
       expressly stated in the immediately proceeding sentence, the Original
       Work is provided under this License on an "AS IS" BASIS and WITHOUT
       WARRANTY, either express or implied, including, without limitation, the
       warranties  of  NON-INFRINGEMENT, MERCHANTABILITY or FITNESS FOR A
       PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY OF THE ORIGINAL
       WORK IS WITH YOU. This DISCLAIMER OF WARRANTY constitutes an essential
       part of this License. No license to Original Work is granted hereunder
       except under this disclaimer.
    8. Limitation of Liability . Under no circumstances and under no legal
       theory, whether in tort (including negligence), contract, or otherwise,
       shall the Licensor be liable to any person for any direct, indirect,
       special, incidental, or consequential damages of any character arising
       as a result of this License or the use of the Original Work including,
       without  limitation,  damages for loss of goodwill, work stoppage,
       computer failure or malfunction, or any and all other commercial damages
       or losses. This limitation of liability shall not apply to liability for
       death or personal injury resulting from Licensor'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.
    9. Acceptance and Termination . If You distribute copies of the Original
       Work or a Derivative Work, You must make a reasonable effort under the
       circumstances to obtain the express assent of recipients to the terms of
       this  License.  Nothing  else but this License (or another written
       agreement between Licensor and You) grants You permission to create
       Derivative Works based upon the Original Work or to exercise any of the
       rights granted in Section 1 herein, and any attempt to do so except
       under the terms of this License (or another written agreement between
       Licensor and You) is expressly prohibited by U.S. copyright law, the
       equivalent  laws  of other countries, and by international treaty.
       Therefore, by exercising any of the rights granted to You in Section 1
       herein, You indicate Your acceptance of this License and all of its
       terms and conditions. This License shall terminate immediately and you
       may no longer exercise any of the rights granted to You by this License
       upon Your failure to honor the proviso in Section 1(c) herein.
   10. Termination  for  Patent  Action  .  This  License shall terminate
       automatically and You may no longer exercise any of the rights granted
       to You by this License as of the date You commence an action, including
       a cross-claim or counterclaim, against Licensor or any licensee alleging
       that the Original Work infringes a patent. This termination provision
       shall  not  apply  for  an  action alleging patent infringement by
       combinations of the Original Work with other software or hardware.
   11. Jurisdiction, Venue and Governing Law . Any action or suit relating to
       this License may be brought only in the courts of a jurisdiction wherein
       the Licensor resides or in which Licensor conducts its primary business,
       and under the laws of that jurisdiction excluding its conflict-of-law
       provisions.  The  application  of the United Nations Convention on
       Contracts for the International Sale of Goods is expressly excluded. Any
       use of the Original Work outside the scope of this License or after its
       termination shall be subject to the requirements and penalties of the
       U.S. Copyright Act, 17 U.S.C. § 101 et seq., the equivalent laws of
       other countries, and international treaty. This section shall survive
       the termination of this License.
   12. Attorneys Fees . In any action to enforce the terms of this License or
       seeking damages relating thereto, the prevailing party shall be entitled
       to  recover its costs and expenses, including, without limitation,
       reasonable attorneys' fees and costs incurred in connection with such
       action, including any appeal of such action. This section shall survive
       the termination of this License.
   13. Miscellaneous  .  This  License  represents the complete agreement
       concerning the 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.
   14. Definition of "You" in This License . "You" throughout this License,
       whether in upper or lower case, means an individual or a legal entity
       exercising rights under, and complying with all of the terms of, this
       License. For legal entities, "You" includes any entity that controls, is
       controlled by, or is under common control with you. For 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.
   15. Right to Use. You may use the Original Work in all ways not otherwise
       restricted  or conditioned by this License or by law, and Licensor
       promises not to interfere with or be responsible for such uses by You.
