   "Object" form shall mean any form resulting from mechanical

   "Work" shall mean the work of authorship, whether in Source or  
   Object form, made available under the License, as indicated by a  
   copyright notice that is included in or attached to the work  
   (an example is provided in the Appendix below).  

   "Derivative Works" shall mean any work, whether in Source or Object  
   form, that is based on (or derived from) the Work and for which the  
   editorial revisions, annotations, elaborations, or other modifications  
   represent, as a whole, an original work of authorship. For the purposes  
   of this License, Derivative Works shall not include works that remain  
   separable from, or merely link (or bind by name) to the interfaces of,  
   the Work and Derivative Works thereof.  

   "Contribution" shall mean any work of authorship, including  
   the original version of the Work and any modifications or additions

   the copyright owner. For the purposes of this definition, "submitted"  
   means any form of electronic, verbal, or written communication sent  
   to the Licensor or its representatives, including but not limited to

   excluding communication that is conspicuously marked or otherwise  
   designated in writing by the copyright owner as "Not a Contribution."  

   "Contributor" shall mean Licensor and any individual or Legal Entity  
   on behalf of whom a Contribution has been received by Licensor and  
   subsequently incorporated within the Work.  

2. Grant of Copyright License.  
   Subject to the terms and conditions of this License, each Contributor  
   hereby grants to You a perpetual, worldwide, non-exclusive, no-charge,  
   royalty-free, irrevocable copyright license to reproduce, prepare  
   Derivative Works of, publicly display, publicly perform, sublicense,  
   and distribute the Work and such Derivative Works in Source or Object form.  

3. Grant of Patent License.  
   Subject to the terms and conditions of this License, each Contributor  
   hereby grants to You a perpetual, worldwide, non-exclusive, no-charge,  
   royalty-free, irrevocable (except as stated in this section) patent  
   license to make, have made, use, offer to sell, sell, import, and  
   otherwise transfer the Work, where such license applies only to those  
   patent claims licensable by such Contributor that are necessarily  
   infringed by their Contribution(s) alone or by combination of their  
   Contribution(s) with the Work to which such Contribution(s) was  
   submitted. If You institute patent litigation against any entity  
   (including a cross-claim or counterclaim in a lawsuit) alleging that  
   the Work or a Contribution incorporated within the Work constitutes  
   direct or contributory patent infringement, then any patent licenses  
   granted to You under this License for that Work shall terminate as of  
   the date such litigation is filed.  

4. Redistribution.  
   You may reproduce and distribute copies of the Work or Derivative  
   Works thereof in any medium, with or without modifications, and in  
   Source or Object form, provided that You meet the following conditions:  

   (a) You must give any other recipients of the Work or Derivative  
       Works a copy of this License; and  

   (b) You must cause any modified files to carry prominent notices  
       stating that You changed the files; and  

   (c) You must retain, in the Source form of any Derivative Works that  
       You distribute, all copyright, patent, trademark, and attribution  
       notices from the Source form of the Work, excluding those notices  
       that do not pertain to any part of the Derivative Works; and  

   (d) If the Work includes a "NOTICE" text file as part of its  
       distribution, then any Derivative Works that You distribute must  
       include a readable copy of the attribution notices contained  
       within such NOTICE file, excluding those notices that do not pertain  
       to any part of the Derivative Works, in at least one of the following  
       places: within a NOTICE text file distributed as part of the  
       Derivative Works; within the Source form or documentation, if  
       provided along with the Derivative Works; or, within a display  
       generated by the Derivative Works, if and wherever such third-party  
       notices normally appear. The contents of the NOTICE file are for  
       informational purposes only and do not modify the License.  

   You may add Your own attribution notices within Derivative Works that  
   You distribute, alongside or as an addendum to the NOTICE text from the  
   Work, provided that such additional attribution notices cannot be  
   construed as modifying the License.  

5. Submission of Contributions.  
   Unless You explicitly state otherwise, any Contribution intentionally  
   submitted for inclusion in the Work by You to the Licensor shall be  
   under the terms and conditions of this License, without any additional  
   terms or conditions. Notwithstanding the above, nothing herein shall  
   supersede or modify the terms of any separate license agreement you may  
   have executed with Licensor regarding such Contributions.  

6. Trademarks.  
   This License does not grant permission to use the trade names, trademarks,  
   service marks, or product names of the Licensor, except as required for  
   reasonable and customary use in describing the origin of the Work and  
   reproducing the content of the NOTICE file.  

7. Disclaimer of Warranty.  
   Unless required by applicable law or agreed to in writing, Licensor provides  
   the Work (and each Contributor provides its Contributions) on an "AS IS"  
   BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or  
   implied, including, without limitation, any warranties or conditions of  
   TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR  
   PURPOSE. You are solely responsible for determining the appropriateness of  
   using or redistributing the Work and assume any risks associated with Your  
   exercise of permissions under this License.  

8. Limitation of Liability.  
   In no event and under no legal theory, whether in tort (including  
   negligence), contract, or otherwise, unless required by applicable law  
   (such as deliberate and grossly negligent acts) or agreed to in writing,  
   shall any Contributor be liable to You for damages, including any direct,  
   indirect, special, incidental, or consequential damages of any character  
   arising as a result of this License or out of the use or inability to use  
   the Work (including but not limited to damages for loss of goodwill, work  
   stoppage, computer failure or malfunction, or any and all other commercial  
   damages or losses), even if such Contributor has been advised of the  
   possibility of such damages.  

9. Accepting Warranty or Additional Liability.  
   While redistributing the Work or Derivative Works thereof, You may choose  
   to offer, and charge a fee for, acceptance of support, warranty, indemnity,  
   or other liability obligations and/or rights consistent with this License.  
   However, in accepting such obligations, You may act only on Your own behalf  
   and on Your sole responsibility, not on behalf of any other Contributor,  
   and only if You agree to indemnify, defend, and hold each Contributor  
   harmless for any liability incurred by, or claims asserted against, such  
   Contributor by reason of your accepting any such warranty or additional  
   liability.
