v. 2.1

This Academic Free License (the "License") applies to any original work of

following notice immediately following the copyright notice for the Original

Licensed under the Academic Free 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

   a) to reproduce the Original Work in copies;

   b) to prepare derivative works ("Derivative Works") based upon the Original

   c) to distribute copies of the Original Work and Derivative Works to the 

   d) to perform the Original Work publicly; and

   e) 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) This section intentionally omitted.

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
   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.

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. par. 101 et seq., the equivalent laws of other countries, and
    international treaty.  This section shall survive the termination of this

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.
