The Academic Free License
v. 2.1

This Academic Free 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 

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. ยง 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 

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.
