Academic Free License v. 2.0
--------------------------------------------------------------------------------
This Academic Free License (the "License") applies to any original work of
authorship (the "Original Work") whose owner (the "Licensor") has placed the
following notice immediately following the copyright notice for the Original
Work:
Licensed under the Academic Free License version 2.0
1) Grant of Copyright License. Licensor hereby grants You a world-wide,
royalty-free, non-exclusive, perpetual, sublicenseable license to do the
following:
a) to reproduce the Original Work in copies;
b) to prepare derivative works ("Derivative Works") based upon the Original
Work;
c) to distribute copies of the Original Work and Derivative Works to the
public;
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 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.
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,
for patent infringement (i) against Licensor with respect to a patent
applicable to software or (ii) against any entity with respect to a patent
applicable to the Original Work (but excluding 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.
