+ Academic Free License
+ Version 1.2
+This Academic Free 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
+Licensed under the Academic Free License version 1.2
+Grant of License. Licensor hereby grants to any person obtaining a
+copy of the Original Work ("You") a world-wide, royalty-free,
+non-exclusive, perpetual, non-sublicenseable license (1) to use, copy,
+modify, merge, publish, perform, distribute and/or sell copies of the
+Original Work and derivative works thereof, and (2) 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 thereof, subject to the
+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.
+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.
+Warranty and Disclaimer of Warranty. Licensor warrants that the copyright
+in and to the Original Work is owned by the Licensor or that the Original
+Work is distributed by Licensor under a valid current license from the
+copyright owner. 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.
+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.
+License to Source Code. 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.
+Mutual 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 if You file a lawsuit in any court alleging that any OSI
+Certified open source software that is licensed under any license containing
+this "Mutual Termination for Patent Action" clause infringes any patent
+claims that are essential to use that software.
+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.
+This license is Copyright (C) 2002 Lawrence E. Rosen. All rights reserved.
+Permission is hereby granted to copy and distribute this license without
+modification. This license may not be modified without the express written
+permission of its copyright owner.
+END OF LICENSE. The following is intended to describe the essential
+differences between the Academic Free License (AFL) version 1.0 and other
+open source licenses:
+The Academic Free License is similar to the BSD, MIT, UoI/NCSA and Apache
+licenses in many respects but it is intended to solve a few problems with
+* The AFL is written so as to make it clear what software is being
+licensed (by the inclusion of a statement following the copyright notice
+in the software). This way, the license functions better than a template
+license. The BSD, MIT and UoI/NCSA licenses apply to unidentified software.
+* The AFL contains a complete copyright grant to the software. The BSD
+and Apache licenses are vague and incomplete in that respect.
+* The AFL contains a complete patent grant to the software. The BSD, MIT,
+UoI/NCSA and Apache licenses rely on an implied patent license and contain
+no explicit patent grant.
+* The AFL makes it clear that no trademark rights are granted to the
+licensor's trademarks. The Apache license contains such a provision, but the
+BSD, MIT and UoI/NCSA licenses do not.
+* The AFL includes the warranty by the licensor that it either owns the
+copyright or that it is distributing the software under a license. None of
+the other licenses contain that warranty. All other warranties are disclaimed,
+as is the case for the other licenses.
+* The AFL is itself copyrighted (with the right granted to copy and distribute
+without modification). This ensures that the owner of the copyright to the
+license will control changes. The Apache license contains a copyright notice,
+but the BSD, MIT and UoI/NCSA licenses do not.
