Grant of Copyright License. Licensor grants You a worldwide, + royalty-free, non-exclusive, sublicensable license, for the duration + of the copyright, to do the following: + a. to reproduce the Original Work in copies, either alone or as part + of a collective work; + b. to translate, adapt, alter, transform, modify, or arrange the + Original Work, thereby creating derivative works ("Derivative + Works") based upon the Original Work; + c. to distribute or communicate copies of the Original Work and + Derivative Works to the public, with the proviso that copies of + Original Work or Derivative Works that You distribute or + communicate shall be licensed under this Transitive Grace Period + Public Licence no later than 12 months after You distributed or + communicated said copies; + d. to perform the Original Work publicly; and + e. to display the Original Work publicly. + 2. Grant of Patent License. Licensor grants You a worldwide, + royalty-free, non-exclusive, sublicensable license, under patent + claims owned or controlled by the Licensor that are embodied in the + Original Work as furnished by the Licensor, for the duration of the + patents, to make, use, sell, offer for sale, have made, and import 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 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. + 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 + permission of the Licensor. Except as expressly stated herein, nothing + in this License grants any license to Licensor's trademarks, + copyrights, patents, trade secrets or any other intellectual property. + No patent license is granted to make, use, sell, offer for sale, have + made, or import embodiments of any patent claims other than the + licensed claims defined in Section 2. No license 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 terms different from this License any + Original Work that Licensor otherwise would have a right to license. + 5. External Deployment. The term "External Deployment" means the use, + distribution, or communication of the Original Work or Derivative + Works in any way such that the Original Work or Derivative Works may + be used by anyone other than You, whether those works are distributed + or communicated to those persons or made available as an application + intended for use over a network. As an express condition for the + grants of license hereunder, You must treat any External Deployment by + You of the Original Work or a Derivative Work as a distribution under + section 1(c). + 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 preceding 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 the Original Work is granted by + this License 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 anyone for any 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 the + extent applicable law prohibits such limitation. + 9. Acceptance and Termination. If, at any time, You expressly assented to + this License, that assent indicates your clear and irrevocable + acceptance of this License and all of its terms and conditions. If You + distribute or communicate 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. + This License conditions your rights to undertake the activities listed + in Section 1, including your right to create Derivative Works based + upon the Original Work, and doing so without honoring these terms and + conditions is prohibited by copyright law and international treaty. + Nothing in this License is intended to affect copyright exceptions and + limitations (including 'fair use' or 'fair dealing'). This License + shall terminate immediately and You may no longer exercise any of the + rights granted to You by this License upon your failure to honor the + conditions in Section 1(c). + 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 copyright or patent law in the + appropriate jurisdiction. 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. 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. + 16. Modification of This License. This License is Copyright (c) 2007 Zooko + Wilcox-O'Hearn. Permission is granted to copy, distribute, or + communicate this License without modification. Nothing in this License + permits You to modify this License as applied to the Original Work or + to Derivative Works. However, You may modify the text of this License + and copy, distribute or communicate your modified version (the + "Modified License") and apply it to other original works of authorship + subject to the following conditions: (i) You may not indicate in any + way that your Modified License is the "Transitive Grace Period Public + Licence" or "TGPPL" and you may not use those names in the name of + your Modified License; and (ii) You must replace the notice specified + in the first paragraph above with the notice "Licensed under " or with + a notice of your own that is not confusingly similar to the notice in + this License. + +------- +Regarding the text "License: BSD3" which appears in +haskell/Codec/FEC.hs: + +On 2008-01-20, Zooko O'Whielacronx wrote: "Will you please give me +rights to use your patches however I like?
