| 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 |
| Original Work: |
| |
| 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 |
| following conditions. |
| |
| 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 |
| those licenses. |
| |
| * 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. |
