      source, and configuration files.

      "Object" form shall mean any form resulting from mechanical
      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
      submitted to Licensor for inclusion in the Work by the copyright owner
      or by an individual or Legal Entity authorized to submit on behalf of
      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

      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.

   END OF TERMS AND CONDITIONS

2.4. Subsequent Licenses
    No Contributor makes additional grants as a result of Your choice to

    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

    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

2.7. Conditions
    Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses

3. Responsibilities
-------------------

3.1. Distribution of Source Form
    All distributions of Covered Software in Source Code Form, including
    purely internal distributions, 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. You must cause any new files containing significant
Example of altering a notice: portions of Covered Software to contain
    an unchanged copy of the notice in Exhibit A.

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
    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 in a text file
included in all distributions of the Covered Software.

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 cure
    any such failure in a reasonable period of time, Your rights under
    this License will be reinstated automatically as of the date of
    termination, provided that You continue to comply with all terms of
    this License. For purposes of this Section 5.1, a reasonable period
    of time is the later of (a) 30 days from the date You were notified
    of the non-compliance; or (b) the first date on which You have the
    practical ability to cure the failure.

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's
    Contribution directly or indirectly infringes any patent, then any
    rights granted to You by any and all Contributors under Sections 2.1
    or 2.2 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.
    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 else 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 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 or in the case of a Contributor, in the jurisdiction
in which the Contributor has its principal place of business, and each
party irrevocably submits to the jurisdiction and venue of such courts.

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 must be attached.

                  GNU LESSER GENERAL PUBLIC LICENSE
                       Version 3, 29 June 2007

 Copyright (C) 2007 Free Software Foundation, Inc. 
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.


  This version of the GNU Lesser General Public License incorporates
the terms and conditions of version 3 of the GNU General Public
License, supplemented by the additional permissions listed below.

  0. Additional Definitions.

  As used herein, "this License" refers to version 3 of the GNU Lesser
General Public License, and the "GNU GPL" refers to version 3 of the GNU
General Public License.

  "The Library" refers to a covered work governed by this License,
other than an Application or a Combined Work as defined below.

  An "Application" is any work that makes use of an interface provided
by the Library, but which is not otherwise based on the Library.
Defining a subclass of a class defined by the Library is deemed a mode
of using an interface provided by the Library.

  A "Combined Work" is a work produced by combining or linking an
Application with the Library.  The particular version of the Library
with which the Combined Work was made is also called the "Linked
Version".

  The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.

  The "Corresponding Application Code" for a Combined Work means the
object code and/or source code for the Application, including any data
and utility programs needed for reproducing the Combined Work from the
Application, but excluding the System Libraries of the Combined Work.

  1. Exception to Section 3 of the GNU GPL.

  You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.

  2. Conveying Modified Versions.

  If you modify a copy of the Library, and, in your modifications, a
facility refers to a function or data to be supplied by an Application
that uses the facility (other than as an argument passed when the
facility is invoked), then you may convey a copy of the modified
version:

   a) under this License, provided that you make a good faith effort to
   ensure that, in the event an Application does not supply the
   function or data, the facility still operates, and performs
   whatever part of its purpose remains meaningful, or

   b) under the GNU GPL, with none of the additional permissions of
   this License applicable to that copy.

  3. Object Code Incorporating Material from Library Header Files.

  The object code form of an Application may incorporate material from
a header file that is part of the Library.  You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and templates
(ten lines or fewer in length), you do both of the following:

   a) Give prominent notice with each copy of the object code that the
   Library is used in it and that the Library and its use are
   covered by this License.

   b) Accompany the object code with a copy of the GNU GPL and this license
   document.

  4. Combined Works.

  You may convey a Combined Work under terms of your choice that,
taken together, effectively do not restrict modification of the
portions of the Library contained in the Combined Work and reverse
engineering for debugging such modifications, if you also do each of
the following:

   a) Give prominent notice with each copy of the Combined Work that
   the Library is used in it and that the Library and its use are
   covered by this License.

   b) Accompany the Combined Work with a copy of the GNU GPL and this license
   document.

   c) For a Combined Work that displays copyright notices during
   execution, include the copyright notice for the Library among
   these notices, as well as a reference directing the user to the
   copies of the GNU GPL and this license document.

   d) Do one of the following:

       0) Convey the Minimal Corresponding Source under the terms of this
       License, and the Corresponding Application Code in a form
       suitable for, and under terms that permit, the user to
       recombine or relink the Application with a modified version of
       the Linked Version to produce a modified Combined Work, in the
       manner specified by section 6 of the GNU GPL for conveying
       Corresponding Source.

       1) Use a suitable shared library mechanism for linking with the
       Library.  A suitable mechanism is one that (i) uses at run time
       a copy of the Library already present on the user's computer
       system, and (ii) will operate properly with a modified version
       of the Library that is interface-compatible with the Linked
       Version.

   e) Provide Installation Information, but only if you would otherwise
   be required to provide such information under section 6 of the
   GNU GPL, and only to the extent that such information is
   necessary to install and execute a modified version of the
   Combined Work produced by recombining or relinking the
   Application with a modified version of the Linked Version. (If
   you use option 4d0, the Installation Information must accompany
   the Minimal Corresponding Source and Corresponding Application
   Code. If you use option 4d1, you must provide the Installation
   Information in the manner specified by section 6 of the GNU GPL
   for conveying Corresponding Source.)

  5. Combined Libraries.

  You may place library facilities that are a work based on the
Library side by side in a single library together with other library
facilities that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:

   a) Accompany the combined library with a copy of the same work based
   on the Library, uncombined with any other library facilities,
   conveyed under the terms of this License.

   b) Give prominent notice with the combined library that part of it
   is a work based on the Library, and explaining where to find the
   accompanying uncombined form of the same work.

  6. Revised Versions of the GNU Lesser General Public License.

  The Free Software Foundation may publish revised and/or new versions
of the GNU Lesser General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.

  Each version is given a distinguishing version number. If the
Library as you received it specifies that a certain numbered version
of the GNU Lesser General Public License "or any later version"
applies to it, you have the option of following the terms and
conditions either of that published version or of any later version
published by the Free Software Foundation. If the Library as you
received it does not specify a version number of the GNU Lesser
General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software
Foundation.

  If the Library as you received it specifies that a proxy can decide
whether future versions of the GNU Lesser General Public License shall
apply, that proxy's public statement of acceptance of any version is
permanent authorization for you to choose that version for the
Library.
