+**************************
+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 © 2005 Lawrence Rosen. 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 "Open Software License" or "OSL" and you may not use those
+names in the name of your Modified License; (ii) You must replace the notice
+specified in the first paragraph above with the notice "Licensed under <insert
+your license name here>" or with a notice of your own that is not confusingly
+similar to the notice in this License; and (iii) You may not claim that your
+original works are open source software unless your Modified License has been
+approved by Open Source Initiative (OSI) and You comply with its license
+review and certification process.
