LICENCE

Academic Free License ("AFL") v. 3.0

This Academic Free License (the "License") applies to any original work
of authorship (the "Original Work") whose owner (the "Licensor") has placed
the following licensing notice adjacent to the copyright notice for the
Original Work:

Licensed under the Academic Free License version 3.0

   1. Grant of Copyright License. Licensor grants You a worldwide, royalty-free,
      non-exclusive, sublicensable license, for the duration of the copyright,
      to do the following:

         a. to reproduce the Original Work in copies, either alone or as part
            of a collective work;

         b. to translate, adapt, alter, transform, modify, or arrange
            the Original Work, thereby creating derivative works
            ("Derivative Works") based upon the Original Work;

         c. to distribute or communicate copies of the Original Work and
            Derivative Works to the public, under any license of your choice
            that does not contradict the terms and conditions, including
            Licensor's reserved rights and remedies, in this Academic Free
            License;

         d. to perform the Original Work publicly; and

         e. to display the Original Work publicly.

   2. Grant of Patent License. Licensor grants You a worldwide, royalty-free,
      non-exclusive, sublicensable license, under patent claims owned
      or controlled by the Licensor that are embodied in the Original Work
      as furnished by the Licensor, for the duration of the patents, to make,
      use, sell, offer for sale, have made, and import 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 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.

   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 permission
      of the Licensor. Except as expressly stated herein, nothing in this
      License grants any license to Licensor's trademarks, copyrights, patents,
      trade secrets or any other intellectual property. No patent license is
      granted to make, use, sell, offer for sale, have made, or import
      embodiments of any patent claims other than the licensed claims defined
      in Section 2. No license 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 terms
      different 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,
      distribution, or communication 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 those works are distributed or
      communicated to those persons or made available as an application
      intended for use over a network. As an express condition for the grants
      of license hereunder, You must treat any External Deployment by You
      of the Original Work or a Derivative Work as a distribution under
      section 1(c).

   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 preceding 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 the Original Work is granted by this License 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 anyone for any 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 the extent applicable law
      prohibits such limitation.

   9. Acceptance and Termination. If, at any time, You expressly assented to
      this License, that assent indicates your clear and irrevocable acceptance
      of this License and all of its terms and conditions. If You distribute
      or communicate 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. This License
      conditions your rights to undertake the activities listed in Section 1,
      including your right to create Derivative Works based upon the Original
      Work, and doing so without honoring these terms and conditions is
      prohibited by copyright law and international treaty. Nothing in this
      License is intended to affect copyright exceptions and limitations
      (including "fair use" or "fair dealing"). 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 conditions
      in Section 1(c).

  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 copyright or patent law in the appropriate jurisdiction. 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. 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.

  16. Modification of This License. This License is
      Copyright © 2005 Lawrence Rosen. Permission is granted to copy,
      distribute, or communicate this License without modification. Nothing
      in this License permits You to modify this License as applied to the
      Original Work or to Derivative Works. However, You may modify the text
      of this License and copy, distribute or communicate your modified version
      (the "Modified License") and apply it to other original works
      of authorship subject to the following conditions: (i) You may not
      indicate in any way that your Modified License is the "Academic Free
      License" or "AFL" and you may not use those names in the name of your
      Modified License; (ii) You must replace the notice specified in the first
      paragraph above with the notice "Licensed under <insert your license name
      here>" or with a notice of your own that is not confusingly similar
      to the notice in this License; and (iii) You may not claim that your
      original works are open source software unless your Modified License has
      been approved by Open Source Initiative (OSI) and You comply with its
      license review and certification process.
