Open Software License v. 3.0 (OSL-3.0)

This Open Software 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 Open Software 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, with the proviso that copies of
    Original Work or Derivative Works that You distribute or
    communicate shall be licensed under this Open Software 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 "Open Software License" or "OSL" 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.
