   transformation or translation of a Source form, including but
   not limited to compiled object code, generated documentation,
   and conversions to other media types.

   "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
   to that Work or Derivative Works thereof, that is intentionally

   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
   communication on electronic mailing lists, source code control systems,
   and issue tracking systems that are managed by, or on behalf of, the
   Licensor for the purpose of discussing and improving the Work, but

   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.

   You may add Your own copyright statement to Your modifications and
   may provide additional or different license terms and conditions
   for use, reproduction, or distribution of Your modifications, or
   for any such Derivative Works as a whole, provided Your use,
   reproduction, and distribution of the Work otherwise complies with
   the conditions stated in this 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.

      form, that is based on (or derived from) the Work and for which the

      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.

          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.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this 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.

      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.

2. License Grants and Conditions

2.1. Grants

     Each Contributor hereby grants You a world-wide, royalty-free,
     non-exclusive license:

     a. under intellectual property rights (other than patent or trademark)
        Licensable by such Contributor to use, reproduce, make available,
        modify, display, perform, distribute, and otherwise exploit its
        Contributions, either on an unmodified basis, with Modifications, or as
        part of a Larger Work; and

     b. under Patent Claims of such Contributor to make, use, sell, offer for
        sale, have made, import, and otherwise transfer either its Contributions
        or its Contributor Version.

2.2. Effective Date

     The licenses granted in Section 2.1 with respect to any Contribution become
     effective for each Contribution on the date the Contributor first distributes
     such Contribution.

2.3. Limitations on Grant Scope

     The licenses granted in this Section 2 are the only rights granted under this
     License. No additional rights or licenses will be implied from the distribution
     or licensing of Covered Software under this License. Notwithstanding Section
     2.1(b) above, no patent license is granted by a Contributor:

     a. for any code that a Contributor has removed from Covered Software; or

     b. for infringements caused by: (i) Your and any other third party’s
        modifications of Covered Software, or (ii) the combination of its
        Contributions with other software (except as part of its Contributor
        Version); or

     c. under Patent Claims infringed by Covered Software in the absence of its
        Contributions.

     This License does not grant any rights in the trademarks, service marks, or
     logos of any Contributor (except as may be necessary to comply with the
     notice requirements in Section 3.4).

2.4. Subsequent Licenses

     No Contributor makes additional grants as a result of Your choice to
     distribute the Covered Software under a subsequent version of this License
     (see Section 10.2) or under the terms of a Secondary License (if permitted
     under the terms of Section 3.3).

2.5. Representation

     Each Contributor represents that the Contributor believes its Contributions
     are its original creation(s) or it has sufficient rights to grant the
     rights to its Contributions conveyed by this License.

2.6. Fair Use

     This License is not intended to limit any rights You have under applicable
     copyright doctrines of fair use, fair dealing, or other equivalents.

2.7. Conditions

     Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
     Section 2.1.


3. Responsibilities

3.1. Distribution of Source Form

     All distribution of Covered Software in Source Code Form, including any
     Modifications that You create or to which You contribute, must be under the
     terms of this License. You must inform recipients that the Source Code Form
     of the Covered Software is governed by the terms of this License, and how
     they can obtain a copy of this License. You may not attempt to alter or
     restrict the recipients’ rights in the Source Code Form.

3.2. Distribution of Executable Form

     If You distribute Covered Software in Executable Form then:

     a. such Covered Software must also be made available in Source Code Form,
        as described in Section 3.1, and You must inform recipients of the
        Executable Form how they can obtain a copy of such Source Code Form by
        reasonable means in a timely manner, at a charge no more than the cost
        of distribution to the recipient; and

     b. You may distribute such Executable Form under the terms of this License,
        or sublicense it under different terms, provided that the license for
        the Executable Form does not attempt to limit or alter the recipients’
        rights in the Source Code Form under this License.

3.3. Distribution of a Larger Work

     You may create and distribute a Larger Work under terms of Your choice,
     provided that You also comply with the requirements of this License for the
     Covered Software. If the Larger Work is a combination of Covered Software
     with a work governed by one or more Secondary Licenses, and the Covered
     Software is not Incompatible With Secondary Licenses, this License permits
     You to additionally distribute such Covered Software under the terms of
     such Secondary License(s), so that the recipient of the Larger Work may, at
     their option, further distribute the Covered Software under the terms of
     either this License or such Secondary License(s).

3.4. Notices

     You may not remove or alter the substance of any license notices (including
     copyright notices, patent notices, disclaimers of warranty, or limitations
     of liability) contained within the Source Code Form of the Covered
     Software, except that You may alter any license notices to the extent
     required to remedy known factual inaccuracies.

3.5. Application of Additional Terms

     You may choose to offer, and to charge a fee for, warranty, support,
     indemnity or liability obligations to one or more recipients of Covered
     Software. However, You may do so only on Your own behalf, and not on behalf
     of any Contributor. You must make it absolutely clear that any such
     warranty, support, indemnity, or liability obligation is offered by You
     alone, and You hereby agree to indemnify every Contributor for any
     liability incurred by such Contributor as a result of warranty, support,
     indemnity or liability terms You offer. You may include additional
     disclaimers of warranty and limitations of liability specific to any
     jurisdiction.

4. Inability to Comply Due to Statute or Regulation

   If it is impossible for You to comply with any of the terms of this License
   with respect to some or all of the Covered Software due to statute, judicial
   order, or regulation then You must: (a) comply with the terms of this License
   to the maximum extent possible; and (b) describe the limitations and the code
   they affect. Such description must be placed in a text file included with all
   distributions of the Covered Software under this License. Except to the
   extent prohibited by statute or regulation, such description must be
   sufficiently detailed for a recipient of ordinary skill to be able to
   understand it.

5. Termination

5.1. The rights granted under this License will terminate automatically if You
     fail to comply with any of its terms. However, if You become compliant,
     then the rights granted under this License from a particular Contributor
     are reinstated (a) provisionally, unless and until such Contributor
     explicitly and finally terminates Your grants, and (b) on an ongoing basis,
     if such Contributor fails to notify You of the non-compliance by some
     reasonable means prior to 60 days after You have come back into compliance.
     Moreover, Your grants from a particular Contributor are reinstated on an
     ongoing basis if such Contributor notifies You of the non-compliance by
     some reasonable means, this is the first time You have received notice of
     non-compliance with this License from such Contributor, and You become
     compliant prior to 30 days after Your receipt of the notice.

5.2. If You initiate litigation against any entity by asserting a patent
     infringement claim (excluding declaratory judgment actions, counter-claims,
     and cross-claims) alleging that a Contributor Version directly or
     indirectly infringes any patent, then the rights granted to You by any and
     all Contributors for the Covered Software under Section 2.1 of this License
     shall terminate.

5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
     license agreements (excluding distributors and resellers) which have been
     validly granted by You or Your distributors under this License prior to
     termination shall survive termination.

6. Disclaimer of Warranty

   Covered Software is provided under this License on an “as is” basis, without
   warranty of any kind, either expressed, implied, or statutory, including,
   without limitation, warranties that the Covered Software is free of defects,
   merchantable, fit for a particular purpose or non-infringing. The entire
   risk as to the quality and performance of the Covered Software is with You.
   Should any Covered Software prove defective in any respect, You (not any
   Contributor) assume the cost of any necessary servicing, repair, or
   correction. This disclaimer of warranty constitutes an essential part of this
   License. No use of  any Covered Software is authorized under this License
   except under this disclaimer.

7. Limitation of Liability

   Under no circumstances and under no legal theory, whether tort (including
   negligence), contract, or otherwise, shall any Contributor, or anyone who
   distributes Covered Software as permitted above, be liable to You for any
   direct, indirect, special, incidental, or consequential damages of any
   character including, without limitation, damages for lost profits, loss of
   goodwill, work stoppage, computer failure or malfunction, or any and all
   other commercial damages or losses, even if such party shall have been
   informed of the possibility of such damages. This limitation of liability
   shall not apply to liability for death or personal injury resulting from such
   party’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.

8. Litigation

   Any litigation relating to this License may be brought only in the courts of
   a jurisdiction where the defendant maintains its principal place of business
   and such litigation shall be governed by laws of that jurisdiction, without
   reference to its conflict-of-law provisions. Nothing in this Section shall
   prevent a party’s ability to bring cross-claims or counter-claims.

9. Miscellaneous

   This License represents the complete agreement concerning the subject matter
   hereof. 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. Any law or regulation which provides that the language of a
   contract shall be construed against the drafter shall not be used to construe
   this License against a Contributor.


10. Versions of the License

10.1. New Versions

      Mozilla Foundation is the license steward. Except as provided in Section
      10.3, no one other than the license steward has the right to modify or
      publish new versions of this License. Each version will be given a
      distinguishing version number.

10.2. Effect of New Versions

      You may distribute the Covered Software under the terms of the version of
      the License under which You originally received the Covered Software, or
      under the terms of any subsequent version published by the license
      steward.

10.3. Modified Versions

      If you create software not governed by this License, and you want to
      create a new license for such software, you may create and use a modified
      version of this License if you rename the license and remove any
      references to the name of the license steward (except to note that such
      modified license differs from this License).

10.4. Distributing Source Code Form that is Incompatible With Secondary Licenses
      If You choose to distribute Source Code Form that is Incompatible With
      Secondary Licenses under the terms of this version of the License, the
      notice described in Exhibit B of this License must be attached.

Exhibit A - Source Code Form License Notice

      obtain one at
      http://mozilla.org/MPL/2.0/.

If it is not possible or desirable to put the notice in a particular file, then

You may add additional accurate notices of copyright ownership.

     a. under intellectual property rights (other than patent or trademark)
        Licensable by such Contributor to use, reproduce, make available,
        modify, display, perform, distribute, and otherwise exploit its
        Contributions, either on an unmodified basis, with Modifications, or as
        part of a Larger Work; and

     b. under Patent Claims of such Contributor to make, use, sell, offer for
        sale, have made, import, and otherwise transfer either its Contributions
        or its Contributor Version.

2.2. Effective Date

     The licenses granted in Section 2.1 with respect to any Contribution become
     effective for each Contribution on the date the Contributor first distributes
     such Contribution.

2.3. Limitations on Grant Scope

     The licenses granted in this Section 2 are the only rights granted under this
     License. No additional rights or licenses will be implied from the distribution
     or licensing of Covered Software under this License. Notwithstanding Section
     2.1(b) above, no patent license is granted by a Contributor:

     a. for any code that a Contributor has removed from Covered Software; or

     b. for infringements caused by: (i) Your and any other third party’s
        modifications of Covered Software, or (ii) the combination of its
        Contributions with other software (except as part of its Contributor
        Version); or

     c. under Patent Claims infringed by Covered Software in the absence of its
        Contributions.

     This License does not grant any rights in the trademarks, service marks, or
     logos of any Contributor (except as may be necessary to comply with the
     notice requirements in Section 3.4).

2.4. Subsequent Licenses

     No Contributor makes additional grants as a result of Your choice to
     distribute the Covered Software under a subsequent version of this License
     (see Section 10.2) or under the terms of a Secondary License (if permitted
     under the terms of Section 3.3).

2.5. Representation

     Each Contributor represents that the Contributor believes its Contributions
     are its original creation(s) or it has sufficient rights to grant the
     rights to its Contributions conveyed by this License.

2.6. Fair Use

     This License is not intended to limit any rights You have under applicable
     copyright doctrines of fair use, fair dealing, or other equivalents.

2.7. Conditions

     Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
     Section 2.1.


3. Responsibilities

3.1. Distribution of Source Form

     All distribution of Covered Software in Source Code Form, including any
     Modifications that You create or to which You contribute, must be under the
     terms of this License. You must inform recipients that the Source Code Form
     of the Covered Software is governed by the terms of this License, and how
     they can obtain a copy of this License. You may not attempt to alter or
     restrict the recipients’ rights in the Source Code Form.

3.2. Distribution of Executable Form

     If You distribute Covered Software in Executable Form then:

     a. such Covered Software must also be made available in Source Code Form,
        as described in Section 3.1, and You must inform recipients of the
        Executable Form how they can obtain a copy of such Source Code Form by
        reasonable means in a timely manner, at a charge no more than the cost
        of distribution to the recipient; and

     b. You may distribute such Executable Form under the terms of this License,
        or sublicense it under different terms, provided that the license for
        the Executable Form does not attempt to limit or alter the recipients’
        rights in the Source Code Form under this License.

3.3. Distribution of a Larger Work

     You may create and distribute a Larger Work under terms of Your choice,
     provided that You also comply with the requirements of this License for the
     Covered Software. If the Larger Work is a combination of Covered Software
     with a work governed by one or more Secondary Licenses, and the Covered
     Software is not Incompatible With Secondary Licenses, this License permits
     You to additionally distribute such Covered Software under the terms of
     such Secondary License(s), so that the recipient of the Larger Work may, at
     their option, further distribute the Covered Software under the terms of
     either this License or such Secondary License(s).

3.4. Notices

     You may not remove or alter the substance of any license notices (including
     copyright notices, patent notices, disclaimers of warranty, or limitations
     of liability) contained within the Source Code Form of the Covered
     Software, except that You may alter any license notices to the extent
     required to remedy known factual inaccuracies.

3.5. Application of Additional Terms

     You may choose to offer, and to charge a fee for, warranty, support,
     indemnity or liability obligations to one or more recipients of Covered
     Software. However, You may do so only on Your own behalf, and not on behalf
     of any Contributor. You must make it absolutely clear that any such
     warranty, support, indemnity, or liability obligation is offered by You
     alone, and You hereby agree to indemnify every Contributor for any
     liability incurred by such Contributor as a result of warranty, support,
     indemnity or liability terms You offer. You may include additional
     disclaimers of warranty and limitations of liability specific to any
     jurisdiction.

4. Inability to Comply Due to Statute or Regulation

   If it is impossible for You to comply with any of the terms of this License
   with respect to some or all of the Covered Software due to statute, judicial
   order, or regulation then You must: (a) comply with the terms of this License
   to the maximum extent possible; and (b) describe the limitations and the code
   they affect. Such description must be placed in a text file included with all
   distributions of the Covered Software under this License. Except to the
   extent prohibited by statute or regulation, such description must be
   sufficiently detailed for a recipient of ordinary skill to be able to
   understand it.

5. Termination

5.1. The rights granted under this License will terminate automatically if You
     fail to comply with any of its terms. However, if You become compliant,
     then the rights granted under this License from a particular Contributor
     are reinstated (a) provisionally, unless and until such Contributor
     explicitly and finally terminates Your grants, and (b) on an ongoing basis,
     if such Contributor fails to notify You of the non-compliance by some
     reasonable means prior to 60 days after You have come back into compliance.
     Moreover, Your grants from a particular Contributor are reinstated on an
     ongoing basis if such Contributor notifies You of the non-compliance by
     some reasonable means, this is the first time You have received notice of
     non-compliance with this License from such Contributor, and You become
     compliant prior to 30 days after Your receipt of the notice.

5.2. If You initiate litigation against any entity by asserting a patent
     infringement claim (excluding declaratory judgment actions, counter-claims,
     and cross-claims) alleging that a Contributor Version directly or
     indirectly infringes any patent, then the rights granted to You by any and
     all Contributors for the Covered Software under Section 2.1 of this License
     shall terminate.

5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
     license agreements (excluding distributors and resellers) which have been
     validly granted by You or Your distributors under this License prior to
     termination shall survive termination.

6. Disclaimer of Warranty

   Covered Software is provided under this License on an “as is” basis, without
   warranty of any kind, either expressed, implied, or statutory, including,
   without limitation, warranties that the Covered Software is free of defects,
   merchantable, fit for a particular purpose or non-infringing. The entire
   risk as to the quality and performance of the Covered Software is with You.
   Should any Covered Software prove defective in any respect, You (not any
   Contributor) assume the cost of any necessary servicing, repair, or
   correction. This disclaimer of warranty constitutes an essential part of this
   License. No use of  any Covered Software is authorized under this License
   except under this disclaimer.

7. Limitation of Liability

   Under no circumstances and under no legal theory, whether tort (including
   negligence), contract, or otherwise, shall any Contributor, or anyone who
   distributes Covered Software as permitted above, be liable to You for any
   direct, indirect, special, incidental, or consequential damages of any
   character including, without limitation, damages for lost profits, loss of
   goodwill, work stoppage, computer failure or malfunction, or any and all
   other commercial damages or losses, even if such party shall have been
   informed of the possibility of such damages. This limitation of liability
   shall not apply to liability for death or personal injury resulting from such
   party’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.

8. Litigation

   Any litigation relating to this License may be brought only in the courts of
   a jurisdiction where the defendant maintains its principal place of business
   and such litigation shall be governed by laws of that jurisdiction, without
   reference to its conflict-of-law provisions. Nothing in this Section shall
   prevent a party’s ability to bring cross-claims or counter-claims.

9. Miscellaneous

   This License represents the complete agreement concerning the subject matter
   hereof. 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. Any law or regulation which provides that the language of a
   contract shall be construed against the drafter shall not be used to construe
   this License against a Contributor.


10. Versions of the License

10.1. New Versions

      Mozilla Foundation is the license steward. Except as provided in Section
      10.3, no one other than the license steward has the right to modify or

      distinguishing version number.

10.2. Effect of New Versions

      You may distribute the Covered Software under the terms of the version of

      steward.

10.3. Modified Versions

      If you create software not governed by this License, and you want to
      create a new license for such software, you may create and use a modified
      version of this License if you rename the license and remove any
      references to the name of the license steward (except to note that such
      modified license differs from this License).

3. Responsibilities

3.1. Distribution of Source Form

     All distribution of Covered Software in Source Code Form, including any
     Modifications that You create or to which You contribute, must be under
     the terms of this License. You must inform recipients that the Source
     Code Form of the Covered Software is governed by the terms of this
     License, and how they can obtain a copy of this License. You may not
     attempt to alter or restrict the recipients' rights in the Source Code
     Form.

3.2. Distribution of Executable Form

     If You distribute Covered Software in Executable Form then:

     a. such Covered Software must also be made available in Source Code Form,
        as described in Section 3.1, and You must inform recipients of the
        Executable Form how they can obtain a copy of such Source Code Form by
        reasonable means in a timely manner, at a charge no more than the cost
        of distribution to the recipient; and

     b. You may distribute such Executable Form under the terms of this
        License, or sublicense it under different terms, provided that the
        license for the Executable Form does not attempt to limit or alter the
        recipients' rights in the Source Code Form under this License.

3.3. Distribution of a Larger Work

     You may create and distribute a Larger Work under terms of Your choice,
     provided that You also comply with the requirements of this License for
     the Covered Software. If the Larger Work is a combination of Covered
     Software with a work governed by one or more Secondary Licenses, and the
     Covered Software is not Incompatible With Secondary Licenses, this
     License permits You to additionally distribute such Covered Software
     under the terms of such Secondary License(s), so that the recipient of
     the Larger Work may, at their option, further distribute the Covered
     Software under the terms of either this License or such Secondary
     License(s).

3.4. Notices

     You may not remove or alter the substance of any license notices
     (including copyright notices, patent notices, disclaimers of warranty, or
     limitations of liability) contained within the Source Code Form of the
     Covered Software, except that You may alter any license notices to the
     extent required to remedy known factual inaccuracies.

3.5. Application of Additional Terms

     You may choose to offer, and to charge a fee for, warranty, support,
     indemnity or liability obligations to one or more recipients of Covered
     Software. However, You may do so only on Your own behalf, and not on
     behalf of any Contributor. You must make it absolutely clear that any
     such warranty, support, indemnity, or liability obligation is offered by
     You alone, and You hereby agree to indemnify every Contributor for any
     liability incurred by such Contributor as a result of warranty, support,
     indemnity or liability terms You offer. You may include additional
     disclaimers of warranty and limitations of liability specific to any
     jurisdiction.

4. Inability to Comply Due to Statute or Regulation

   If it is impossible for You to comply with any of the terms of this License
   with respect to some or all of the Covered Software due to statute,
   judicial order, or regulation then You must: (a) comply with the terms of
   this License to the maximum extent possible; and (b) describe the
   limitations and the code they affect. Such description must be placed in a
   text file included with all distributions of the Covered Software under
   this License. Except to the extent prohibited by statute or regulation,
   such description must be sufficiently detailed for a recipient of ordinary
   skill to be able to understand it.

5. Termination

5.1. The rights granted under this License will terminate automatically if You
     fail to comply with any of its terms. However, if You become compliant,
     then the rights granted under this License from a particular Contributor
     are reinstated (a) provisionally, unless and until such Contributor
     explicitly and finally terminates Your grants, and (b) on an ongoing
     basis, if such Contributor fails to notify You of the non-compliance by
     some reasonable means prior to 60 days after You have come back into
     compliance. Moreover, Your grants from a particular Contributor are
     reinstated on an ongoing basis if such Contributor notifies You of the
     non-compliance by some reasonable means, this is the first time You have
     received notice of non-compliance with this License from such
     Contributor, and You become compliant prior to 30 days after Your receipt
     of the notice.

5.2. If You initiate litigation against any entity by asserting a patent
     infringement claim (excluding declaratory judgment actions,
     counter-claims, and cross-claims) alleging that a Contributor Version
     directly or indirectly infringes any patent, then the rights granted to
     You by any and all Contributors for the Covered Software under Section
     2.1 of this License shall terminate.

5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
     license agreements (excluding distributors and resellers) which have been
     validly granted by You or Your distributors under this License prior to
     termination shall survive termination.

6. Disclaimer of Warranty

   Covered Software is provided under this License on an "as is" basis,
   without warranty of any kind, either expressed, implied, or statutory,
   including, without limitation, warranties that the Covered Software is free
   of defects, merchantable, fit for a particular purpose or non-infringing.
   The entire risk as to the quality and performance of the Covered Software
   is with You. Should any Covered Software prove defective in any respect,
   You (not any Contributor) assume the cost of any necessary servicing,
   repair, or correction. This disclaimer of warranty constitutes an essential
   part of this License. No use of  any Covered Software is authorized under
   this License except under this disclaimer.

7. Limitation of Liability

   Under no circumstances and under no legal theory, whether tort (including
   negligence), contract, or otherwise, shall any Contributor, or anyone who
   distributes Covered Software as permitted above, be liable to You for any
   direct, indirect, special, incidental, or consequential damages of any
   character including, without limitation, damages for lost profits, loss of
   goodwill, work stoppage, computer failure or malfunction, or any and all
   other commercial damages or losses, even if such party shall have been
   informed of the possibility of such damages. This limitation of liability
   shall not apply to liability for death or personal injury resulting from
   such party'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.

8. Litigation

   Any litigation relating to this License may be brought only in the courts
   of a jurisdiction where the defendant maintains its principal place of
   business and such litigation shall be governed by laws of that
   jurisdiction, without reference to its conflict-of-law provisions. Nothing
   in this Section shall prevent a party's ability to bring cross-claims or
   counter-claims.

9. Miscellaneous

   This License represents the complete agreement concerning the subject
   matter hereof. 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. Any law or regulation which provides that
   the language of a contract shall be construed against the drafter shall not
   be used to construe this License against a Contributor.

     a. under intellectual property rights (other than patent or trademark)
        Licensable by such Contributor to use, reproduce, make available,
        modify, display, perform, distribute, and otherwise exploit its
        Contributions, either on an unmodified basis, with Modifications, or as

     effective for each Contribution on the date the Contributor first distributes
     such Contribution.

2.3. Limitations on Grant Scope

     The licenses granted in this Section 2 are the only rights granted under this
     License. No additional rights or licenses will be implied from the distribution
     or licensing of Covered Software under this License. Notwithstanding Section
     2.1(b) above, no patent license is granted by a Contributor:

     a. for any code that a Contributor has removed from Covered Software; or

     b. for infringements caused by: (i) Your and any other third party’s
        modifications of Covered Software, or (ii) the combination of its
        Contributions with other software (except as part of its Contributor
        Version); or

     c. under Patent Claims infringed by Covered Software in the absence of its
        Contributions.

     This License does not grant any rights in the trademarks, service marks, or
     logos of any Contributor (except as may be necessary to comply with the
     notice requirements in Section 3.4).

2.4. Subsequent Licenses

     No Contributor makes additional grants as a result of Your choice to
     distribute the Covered Software under a subsequent version of this License
     (see Section 10.2) or under the terms of a Secondary License (if permitted
     under the terms of Section 3.3).

2.5. Representation

     Each Contributor represents that the Contributor believes its Contributions
     are its original creation(s) or it has sufficient rights to grant the
     rights to its Contributions conveyed by this License.

2.6. Fair Use

     This License is not intended to limit any rights You have under applicable
     copyright doctrines of fair use, fair dealing, or other equivalents.

2.7. Conditions

     Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
     Section 2.1.


3. Responsibilities

3.1. Distribution of Source Form

     All distribution of Covered Software in Source Code Form, including any
     Modifications that You create or to which You contribute, must be under the
     terms of this License. You must inform recipients that the Source Code Form
     of the Covered Software is governed by the terms of this License, and how
     they can obtain a copy of this License. You may not attempt to alter or
     restrict the recipients’ rights in the Source Code Form.

3.2. Distribution of Executable Form

     If You distribute Covered Software in Executable Form then:

     a. such Covered Software must also be made available in Source Code Form,
        as described in Section 3.1, and You must inform recipients of the
        Executable Form how they can obtain a copy of such Source Code Form by
        reasonable means in a timely manner, at a charge no more than the cost
        of distribution to the recipient; and

     b. You may distribute such Executable Form under the terms of this License,
        or sublicense it under different terms, provided that the license for
        the Executable Form does not attempt to limit or alter the recipients’
        rights in the Source Code Form under this License.

3.3. Distribution of a Larger Work

     You may create and distribute a Larger Work under terms of Your choice,
     provided that You also comply with the requirements of this License for the
     Covered Software. If the Larger Work is a combination of Covered Software
     with a work governed by one or more Secondary Licenses, and the Covered
     Software is not Incompatible With Secondary Licenses, this License permits
     You to additionally distribute such Covered Software under the terms of
     such Secondary License(s), so that the recipient of the Larger Work may, at
     their option, further distribute the Covered Software under the terms of
     either this License or such Secondary License(s).

3.4. Notices

     You may not remove or alter the substance of any license notices (including
     copyright notices, patent notices, disclaimers of warranty, or limitations
     of liability) contained within the Source Code Form of the Covered
     Software, except that You may alter any license notices to the extent
     required to remedy known factual inaccuracies.

3.5. Application of Additional Terms

     You may choose to offer, and to charge a fee for, warranty, support,
     indemnity or liability obligations to one or more recipients of Covered
     Software. However, You may do so only on Your own behalf, and not on behalf
     of any Contributor. You must make it absolutely clear that any such
     warranty, support, indemnity, or liability obligation is offered by You
     alone, and You hereby agree to indemnify every Contributor for any
     liability incurred by such Contributor as a result of warranty, support,
     indemnity or liability terms You offer. You may include additional
     disclaimers of warranty and limitations of liability specific to any
     jurisdiction.

4. Inability to Comply Due to Statute or Regulation

   If it is impossible for You to comply with any of the terms of this License
   with respect to some or all of the Covered Software due to statute, judicial
   order, or regulation then You must: (a) comply with the terms of this License
   to the maximum extent possible; and (b) describe the limitations and the code
   they affect. Such description must be placed in a text file included with all
   distributions of the Covered Software under this License. Except to the
   extent prohibited by statute or regulation, such description must be
   sufficiently detailed for a recipient of ordinary skill to be able to
   understand it.

5. Termination

5.1. The rights granted under this License will terminate automatically if You
     fail to comply with any of its terms. However, if You become compliant,
     then the rights granted under this License from a particular Contributor
     are reinstated (a) provisionally, unless and until such Contributor
     explicitly and finally terminates Your grants, and (b) on an ongoing basis,
     if such Contributor fails to notify You of the non-compliance by some
     reasonable means prior to 60 days after You have come back into compliance.
     Moreover, Your grants from a particular Contributor are reinstated on an
     ongoing basis if such Contributor notifies You of the non-compliance by
     some reasonable means, this is the first time You have received notice of
     non-compliance with this License from such Contributor, and You become
     compliant prior to 30 days after Your receipt of the notice.

5.2. If You initiate litigation against any entity by asserting a patent
     infringement claim (excluding declaratory judgment actions, counter-claims,
     and cross-claims) alleging that a Contributor Version directly or
     indirectly infringes any patent, then the rights granted to You by any and
     all Contributors for the Covered Software under Section 2.1 of this License
     shall terminate.

5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
     license agreements (excluding distributors and resellers) which have been
     validly granted by You or Your distributors under this License prior to
     termination shall survive termination.

6. Disclaimer of Warranty

   Covered Software is provided under this License on an “as is” basis, without
   warranty of any kind, either expressed, implied, or statutory, including,
   without limitation, warranties that the Covered Software is free of defects,
   merchantable, fit for a particular purpose or non-infringing. The entire
   risk as to the quality and performance of the Covered Software is with You.
   Should any Covered Software prove defective in any respect, You (not any
   Contributor) assume the cost of any necessary servicing, repair, or
   correction. This disclaimer of warranty constitutes an essential part of this
   License. No use of  any Covered Software is authorized under this License
   except under this disclaimer.

7. Limitation of Liability

   Under no circumstances and under no legal theory, whether tort (including
   negligence), contract, or otherwise, shall any Contributor, or anyone who
   distributes Covered Software as permitted above, be liable to You for any
   direct, indirect, special, incidental, or consequential damages of any
   character including, without limitation, damages for lost profits, loss of
   goodwill, work stoppage, computer failure or malfunction, or any and all
   other commercial damages or losses, even if such party shall have been
   informed of the possibility of such damages. This limitation of liability
   shall not apply to liability for death or personal injury resulting from such
   party’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.

8. Litigation

   Any litigation relating to this License may be brought only in the courts of
   a jurisdiction where the defendant maintains its principal place of business
   and such litigation shall be governed by laws of that jurisdiction, without
   reference to its conflict-of-law provisions. Nothing in this Section shall
   prevent a party’s ability to bring cross-claims or counter-claims.

9. Miscellaneous

   This License represents the complete agreement concerning the subject matter
   hereof. 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. Any law or regulation which provides that the language of a
   contract shall be construed against the drafter shall not be used to construe
   this License against a Contributor.


10. Versions of the License

10.1. New Versions

      Mozilla Foundation is the license steward. Except as provided in Section
      10.3, no one other than the license steward has the right to modify or

      steward.

10.3. Modified Versions

      If you create software not governed by this License, and you want to
      create a new license for such software, you may create and use a modified
      version of this License if you rename the license and remove any
      references to the name of the license steward (except to note that such
      modified license differs from this License).

     warranty, support, indemnity, or liability obligation is offered by You
     alone, and You hereby agree to indemnify every Contributor for any
     liability incurred by such Contributor as a result of warranty, support,
     indemnity or liability terms You offer. You may include additional

   understand it.

5. Termination

5.1. The rights granted under this License will terminate automatically if You
     fail to comply with any of its terms. However, if You become compliant,
     then the rights granted under this License from a particular Contributor
     are reinstated (a) provisionally, unless and until such Contributor
     explicitly and finally terminates Your grants, and (b) on an ongoing basis,
     if such Contributor fails to notify You of the non-compliance by some
     reasonable means prior to 60 days after You have come back into compliance.
     Moreover, Your grants from a particular Contributor are reinstated on an
     ongoing basis if such Contributor notifies You of the non-compliance by
     some reasonable means, this is the first time You have received notice of
     non-compliance with this License from such Contributor, and You become
     compliant prior to 30 days after Your receipt of the notice.

5.2. If You initiate litigation against any entity by asserting a patent
     infringement claim (excluding declaratory judgment actions, counter-claims,
     and cross-claims) alleging that a Contributor Version directly or
     indirectly infringes any patent, then the rights granted to You by any and
     all Contributors for the Covered Software under Section 2.1 of this License
     shall terminate.

5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user

     validly granted by You or Your distributors under this License prior to
     termination shall survive termination.

6. Disclaimer of Warranty

   Covered Software is provided under this License on an “as is” basis, without
   warranty of any kind, either expressed, implied, or statutory, including,
   without limitation, warranties that the Covered Software is free of defects,
   merchantable, fit for a particular purpose or non-infringing. The entire
   risk as to the quality and performance of the Covered Software is with You.
   Should any Covered Software prove defective in any respect, You (not any
   Contributor) assume the cost of any necessary servicing, repair, or
   correction. This disclaimer of warranty constitutes an essential part of this
   License. No use of  any Covered Software is authorized under this License
   except under this disclaimer.

7. Limitation of Liability

   Under no circumstances and under no legal theory, whether tort (including
   negligence), contract, or otherwise, shall any Contributor, or anyone who
   distributes Covered Software as permitted above, be liable to You for any
   direct, indirect, special, incidental, or consequential damages of any
   character including, without limitation, damages for lost profits, loss of
   goodwill, work stoppage, computer failure or malfunction, or any and all
   other commercial damages or losses, even if such party shall have been
   informed of the possibility of such damages. This limitation of liability
   shall not apply to liability for death or personal injury resulting from such
   party’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.

8. Litigation

   Any litigation relating to this License may be brought only in the courts of
   a jurisdiction where the defendant maintains its principal place of business
   and such litigation shall be governed by laws of that jurisdiction, without
   reference to its conflict-of-law provisions. Nothing in this Section shall
   prevent a party’s ability to bring cross-claims or counter-claims.

9. Miscellaneous

   This License represents the complete agreement concerning the subject matter
   hereof. 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. Any law or regulation which provides that the language of a
   contract shall be construed against the drafter shall not be used to construe

        Licensable by such Contributor to use, reproduce, make available,

     License. No additional rights or licenses will be implied from the distribution
     or licensing of Covered Software under this License. Notwithstanding Section
     2.1(b) above, no patent license is granted by a Contributor:

     a. for any code that a Contributor has removed from Covered Software; or

     b. for infringements caused by: (i) Your and any other third party’s
        modifications of Covered Software, or (ii) the combination of its
        Contributions with other software (except as part of its Contributor
        Version); or

     c. under Patent Claims infringed by Covered Software in the absence of its
        Contributions.

     This License does not grant any rights in the trademarks, service marks, or
     logos of any Contributor (except as may be necessary to comply with the
     notice requirements in Section 3.4).

2.4. Subsequent Licenses

     distribute the Covered Software under a subsequent version of this License
     (see Section 10.2) or under the terms of a Secondary License (if permitted
     under the terms of Section 3.3).

2.5. Representation

     Each Contributor represents that the Contributor believes its Contributions
     are its original creation(s) or it has sufficient rights to grant the
     rights to its Contributions conveyed by this License.

2.6. Fair Use

     copyright doctrines of fair use, fair dealing, or other equivalents.

3. Responsibilities

3.1. Distribution of Source Form

     All distribution of Covered Software in Source Code Form, including any
     Modifications that You create or to which You contribute, must be under the
     terms of this License. You must inform recipients that the Source Code Form
     of the Covered Software is governed by the terms of this License, and how
     they can obtain a copy of this License. You may not attempt to alter or
     restrict the recipients’ rights in the Source Code Form.

3.2. Distribution of Executable Form

     If You distribute Covered Software in Executable Form then:

     a. such Covered Software must also be made available in Source Code Form,
        as described in Section 3.1, and You must inform recipients of the
        Executable Form how they can obtain a copy of such Source Code Form by
        reasonable means in a timely manner, at a charge no more than the cost
        of distribution to the recipient; and

     b. You may distribute such Executable Form under the terms of this License,
        or sublicense it under different terms, provided that the license for
        the Executable Form does not attempt to limit or alter the recipients’
        rights in the Source Code Form under this License.

3.3. Distribution of a Larger Work

     You may create and distribute a Larger Work under terms of Your choice,
     provided that You also comply with the requirements of this License for the
     Covered Software. If the Larger Work is a combination of Covered Software
     with a work governed by one or more Secondary Licenses, and the Covered
     Software is not Incompatible With Secondary Licenses, this License permits
     You to additionally distribute such Covered Software under the terms of
     such Secondary License(s), so that the recipient of the Larger Work may, at
     their option, further distribute the Covered Software under the terms of
     either this License or such Secondary License(s).

3.4. Notices

     You may not remove or alter the substance of any license notices (including
     copyright notices, patent notices, disclaimers of warranty, or limitations
     of liability) contained within the Source Code Form of the Covered
     Software, except that You may alter any license notices to the extent
     required to remedy known factual inaccuracies.

3.5. Application of Additional Terms

     You may choose to offer, and to charge a fee for, warranty, support,
     indemnity or liability obligations to one or more recipients of Covered
     Software. However, You may do so only on Your own behalf, and not on behalf
     of any Contributor. You must make it absolutely clear that any such
     warranty, support, indemnity, or liability obligation is offered by You
     alone, and You hereby agree to indemnify every Contributor for any
     liability incurred by such Contributor as a result of warranty, support,
     indemnity or liability terms You offer. You may include additional
     disclaimers of warranty and limitations of liability specific to any
     jurisdiction.

4. Inability to Comply Due to Statute or Regulation

   If it is impossible for You to comply with any of the terms of this License
   with respect to some or all of the Covered Software due to statute, judicial
   order, or regulation then You must: (a) comply with the terms of this License
   to the maximum extent possible; and (b) describe the limitations and the code
   they affect. Such description must be placed in a text file included with all
   distributions of the Covered Software under this License. Except to the
   extent prohibited by statute or regulation, such description must be
   sufficiently detailed for a recipient of ordinary skill to be able to
   understand it.

5. Termination

5.1. The rights granted under this License will terminate automatically if You
     fail to comply with any of its terms. However, if You become compliant,
     then the rights granted under this License from a particular Contributor
     are reinstated (a) provisionally, unless and until such Contributor
     explicitly and finally terminates Your grants, and (b) on an ongoing basis,
     if such Contributor fails to notify You of the non-compliance by some
     reasonable means prior to 60 days after You have come back into compliance.
     Moreover, Your grants from a particular Contributor are reinstated on an
     ongoing basis if such Contributor notifies You of the non-compliance by
     some reasonable means, this is the first time You have received notice of
     non-compliance with this License from such Contributor, and You become
     compliant prior to 30 days after Your receipt of the notice.

5.2. If You initiate litigation against any entity by asserting a patent
     infringement claim (excluding declaratory judgment actions, counter-claims,
     and cross-claims) alleging that a Contributor Version directly or
     indirectly infringes any patent, then the rights granted to You by any and
     all Contributors for the Covered Software under Section 2.1 of this License
     shall terminate.

5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
     license agreements (excluding distributors and resellers) which have been
     validly granted by You or Your distributors under this License prior to
     termination shall survive termination.

6. Disclaimer of Warranty

   Covered Software is provided under this License on an “as is” basis, without
   warranty of any kind, either expressed, implied, or statutory, including,
   without limitation, warranties that the Covered Software is free of defects,
   merchantable, fit for a particular purpose or non-infringing. The entire
   risk as to the quality and performance of the Covered Software is with You.
   Should any Covered Software prove defective in any respect, You (not any
   Contributor) assume the cost of any necessary servicing, repair, or
   correction. This disclaimer of warranty constitutes an essential part of this
   License. No use of  any Covered Software is authorized under this License
   except under this disclaimer.

7. Limitation of Liability

   Under no circumstances and under no legal theory, whether tort (including
   negligence), contract, or otherwise, shall any Contributor, or anyone who
   distributes Covered Software as permitted above, be liable to You for any
   direct, indirect, special, incidental, or consequential damages of any
   character including, without limitation, damages for lost profits, loss of
   goodwill, work stoppage, computer failure or malfunction, or any and all
   other commercial damages or losses, even if such party shall have been
   informed of the possibility of such damages. This limitation of liability
   shall not apply to liability for death or personal injury resulting from such
   party’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.

8. Litigation

   Any litigation relating to this License may be brought only in the courts of
   a jurisdiction where the defendant maintains its principal place of business
   and such litigation shall be governed by laws of that jurisdiction, without
   reference to its conflict-of-law provisions. Nothing in this Section shall
   prevent a party’s ability to bring cross-claims or counter-claims.

9. Miscellaneous

   This License represents the complete agreement concerning the subject matter
   hereof. 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. Any law or regulation which provides that the language of a
   contract shall be construed against the drafter shall not be used to construe
   this License against a Contributor.

     Moreover, Your grants from a particular Contributor are reinstated on an

   Covered Software is provided under this License on an “as is” basis, without
   warranty of any kind, either expressed, implied, or statutory, including,
   without limitation, warranties that the Covered Software is free of defects,
   merchantable, fit for a particular purpose or non-infringing. The entire
   risk as to the quality and performance of the Covered Software is with You.
   Should any Covered Software prove defective in any respect, You (not any
   Contributor) assume the cost of any necessary servicing, repair, or
   correction. This disclaimer of warranty constitutes an essential part of this
   License. No use of  any Covered Software is authorized under this License
   except under this disclaimer.

7. Limitation of Liability

   Under no circumstances and under no legal theory, whether tort (including
   negligence), contract, or otherwise, shall any Contributor, or anyone who
   distributes Covered Software as permitted above, be liable to You for any
   direct, indirect, special, incidental, or consequential damages of any
   character including, without limitation, damages for lost profits, loss of
   goodwill, work stoppage, computer failure or malfunction, or any and all
   other commercial damages or losses, even if such party shall have been
   informed of the possibility of such damages. This limitation of liability
   shall not apply to liability for death or personal injury resulting from such
   party’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.

8. Litigation

   Any litigation relating to this License may be brought only in the courts of
   a jurisdiction where the defendant maintains its principal place of business
   and such litigation shall be governed by laws of that jurisdiction, without
   reference to its conflict-of-law provisions. Nothing in this Section shall
   prevent a party’s ability to bring cross-claims or counter-claims.

9. Miscellaneous

   This License represents the complete agreement concerning the subject matter
   hereof. 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. Any law or regulation which provides that the language of a
   contract shall be construed against the drafter shall not be used to construe
   this License against a Contributor.


10. Versions of the License

10.1. New Versions

      Mozilla Foundation is the license steward. Except as provided in Section
      10.3, no one other than the license steward has the right to modify or
      publish new versions of this License. Each version will be given a
      distinguishing version number.

10.2. Effect of New Versions

      You may distribute the Covered Software under the terms of the version of
      the License under which You originally received the Covered Software, or
      under the terms of any subsequent version published by the license
      steward.

10.3. Modified Versions

      If you create software not governed by this License, and you want to
      create a new license for such software, you may create and use a modified
      version of this License if you rename the license and remove any
      references to the name of the license steward (except to note that such
      modified license differs from this License).

2. License Grants and Conditions

2.1. Grants

     Each Contributor hereby grants You a world-wide, royalty-free,
     non-exclusive license:

     a. under intellectual property rights (other than patent or trademark)
        Licensable by such Contributor to use, reproduce, make available,
        modify, display, perform, distribute, and otherwise exploit its
        Contributions, either on an unmodified basis, with Modifications, or as
        part of a Larger Work; and

     b. under Patent Claims of such Contributor to make, use, sell, offer for
        sale, have made, import, and otherwise transfer either its Contributions
        or its Contributor Version.

2.2. Effective Date

     The licenses granted in Section 2.1 with respect to any Contribution become
     effective for each Contribution on the date the Contributor first distributes
     such Contribution.

2.3. Limitations on Grant Scope

     The licenses granted in this Section 2 are the only rights granted under this
     License. No additional rights or licenses will be implied from the distribution
     or licensing of Covered Software under this License. Notwithstanding Section
     2.1(b) above, no patent license is granted by a Contributor:

     a. for any code that a Contributor has removed from Covered Software; or

     b. for infringements caused by: (i) Your and any other third party’s
        modifications of Covered Software, or (ii) the combination of its
        Contributions with other software (except as part of its Contributor
        Version); or

     c. under Patent Claims infringed by Covered Software in the absence of its
        Contributions.

     This License does not grant any rights in the trademarks, service marks, or
     logos of any Contributor (except as may be necessary to comply with the
     notice requirements in Section 3.4).

2.4. Subsequent Licenses

     No Contributor makes additional grants as a result of Your choice to
     distribute the Covered Software under a subsequent version of this License
     (see Section 10.2) or under the terms of a Secondary License (if permitted
     under the terms of Section 3.3).

2.5. Representation

     Each Contributor represents that the Contributor believes its Contributions
     are its original creation(s) or it has sufficient rights to grant the
     rights to its Contributions conveyed by this License.

2.6. Fair Use

     This License is not intended to limit any rights You have under applicable
     copyright doctrines of fair use, fair dealing, or other equivalents.

2.7. Conditions

     Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in

3. Responsibilities

3.1. Distribution of Source Form

     All distribution of Covered Software in Source Code Form, including any
     Modifications that You create or to which You contribute, must be under the
     terms of this License. You must inform recipients that the Source Code Form
     of the Covered Software is governed by the terms of this License, and how
     they can obtain a copy of this License. You may not attempt to alter or
     restrict the recipients’ rights in the Source Code Form.

3.2. Distribution of Executable Form

     If You distribute Covered Software in Executable Form then:

     a. such Covered Software must also be made available in Source Code Form,
        as described in Section 3.1, and You must inform recipients of the
        Executable Form how they can obtain a copy of such Source Code Form by
        reasonable means in a timely manner, at a charge no more than the cost
        of distribution to the recipient; and

     b. You may distribute such Executable Form under the terms of this License,
        or sublicense it under different terms, provided that the license for
        the Executable Form does not attempt to limit or alter the recipients’
        rights in the Source Code Form under this License.

3.3. Distribution of a Larger Work

     You may create and distribute a Larger Work under terms of Your choice,
     provided that You also comply with the requirements of this License for the
     Covered Software. If the Larger Work is a combination of Covered Software
     with a work governed by one or more Secondary Licenses, and the Covered
     Software is not Incompatible With Secondary Licenses, this License permits
     You to additionally distribute such Covered Software under the terms of
     such Secondary License(s), so that the recipient of the Larger Work may, at
     their option, further distribute the Covered Software under the terms of
     either this License or such Secondary License(s).

3.4. Notices

     You may not remove or alter the substance of any license notices (including
     copyright notices, patent notices, disclaimers of warranty, or limitations
     of liability) contained within the Source Code Form of the Covered
     Software, except that You may alter any license notices to the extent
     required to remedy known factual inaccuracies.

3.5. Application of Additional Terms

     You may choose to offer, and to charge a fee for, warranty, support,
     indemnity or liability obligations to one or more recipients of Covered
     Software. However, You may do so only on Your own behalf, and not on behalf
     of any Contributor. You must make it absolutely clear that any such
     warranty, support, indemnity, or liability obligation is offered by You
     alone, and You hereby agree to indemnify every Contributor for any
     liability incurred by such Contributor as a result of warranty, support,
     indemnity or liability terms You offer. You may include additional
     disclaimers of warranty and limitations of liability specific to any
     jurisdiction.

4. Inability to Comply Due to Statute or Regulation

   If it is impossible for You to comply with any of the terms of this License
   with respect to some or all of the Covered Software due to statute, judicial
   order, or regulation then You must: (a) comply with the terms of this License
   to the maximum extent possible; and (b) describe the limitations and the code
   they affect. Such description must be placed in a text file included with all
   distributions of the Covered Software under this License. Except to the
   extent prohibited by statute or regulation, such description must be
   sufficiently detailed for a recipient of ordinary skill to be able to
   understand it.

5. Termination

5.1. The rights granted under this License will terminate automatically if You
     fail to comply with any of its terms. However, if You become compliant,
     then the rights granted under this License from a particular Contributor
     are reinstated (a) provisionally, unless and until such Contributor
     explicitly and finally terminates Your grants, and (b) on an ongoing basis,
     if such Contributor fails to notify You of the non-compliance by some
     reasonable means prior to 60 days after You have come back into compliance.
     Moreover, Your grants from a particular Contributor are reinstated on an
     ongoing basis if such Contributor notifies You of the non-compliance by
     some reasonable means, this is the first time You have received notice of
     non-compliance with this License from such Contributor, and You become
     compliant prior to 30 days after Your receipt of the notice.

5.2. If You initiate litigation against any entity by asserting a patent
     infringement claim (excluding declaratory judgment actions, counter-claims,
     and cross-claims) alleging that a Contributor Version directly or
     indirectly infringes any patent, then the rights granted to You by any and
     all Contributors for the Covered Software under Section 2.1 of this License
     shall terminate.

5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
     license agreements (excluding distributors and resellers) which have been
     validly granted by You or Your distributors under this License prior to
     termination shall survive termination.

6. Disclaimer of Warranty

   Covered Software is provided under this License on an “as is” basis, without
   warranty of any kind, either expressed, implied, or statutory, including,
   without limitation, warranties that the Covered Software is free of defects,
   merchantable, fit for a particular purpose or non-infringing. The entire
   risk as to the quality and performance of the Covered Software is with You.
   Should any Covered Software prove defective in any respect, You (not any
   Contributor) assume the cost of any necessary servicing, repair, or
   correction. This disclaimer of warranty constitutes an essential part of this
   License. No use of  any Covered Software is authorized under this License
   except under this disclaimer.

7. Limitation of Liability

   Under no circumstances and under no legal theory, whether tort (including
   negligence), contract, or otherwise, shall any Contributor, or anyone who
   distributes Covered Software as permitted above, be liable to You for any
   direct, indirect, special, incidental, or consequential damages of any
   character including, without limitation, damages for lost profits, loss of
   goodwill, work stoppage, computer failure or malfunction, or any and all
   other commercial damages or losses, even if such party shall have been
   informed of the possibility of such damages. This limitation of liability
   shall not apply to liability for death or personal injury resulting from such
   party’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.

8. Litigation

   Any litigation relating to this License may be brought only in the courts of
   a jurisdiction where the defendant maintains its principal place of business
   and such litigation shall be governed by laws of that jurisdiction, without
   reference to its conflict-of-law provisions. Nothing in this Section shall
   prevent a party’s ability to bring cross-claims or counter-claims.

9. Miscellaneous

   This License represents the complete agreement concerning the subject matter
   hereof. 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. Any law or regulation which provides that the language of a
   contract shall be construed against the drafter shall not be used to construe
   this License against a Contributor.


10. Versions of the License

10.1. New Versions

      Mozilla Foundation is the license steward. Except as provided in Section
      10.3, no one other than the license steward has the right to modify or
      publish new versions of this License. Each version will be given a
      distinguishing version number.

10.2. Effect of New Versions

      You may distribute the Covered Software under the terms of the version of
      the License under which You originally received the Covered Software, or
      under the terms of any subsequent version published by the license
      steward.

10.3. Modified Versions

      If you create software not governed by this License, and you want to
      create a new license for such software, you may create and use a modified
      version of this License if you rename the license and remove any
      references to the name of the license steward (except to note that such
      modified license differs from this License).

10.4. Distributing Source Code Form that is Incompatible With Secondary Licenses
      If You choose to distribute Source Code Form that is Incompatible With
      Secondary Licenses under the terms of this version of the License, the
      notice described in Exhibit B of this License must be attached.

Exhibit A - Source Code Form License Notice

      This Source Code Form is subject to the
      terms of the Mozilla Public License, v.
      2.0. If a copy of the MPL was not
      distributed with this file, You can
      obtain one at
      http://mozilla.org/MPL/2.0/.

If it is not possible or desirable to put the notice in a particular file, then

directory) where a recipient would be likely to look for such a notice.

You may add additional accurate notices of copyright ownership.

Exhibit B - “Incompatible With Secondary Licenses” Notice

      This Source Code Form is “Incompatible
