       "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

       of this License, Derivative Works shall not include works that remain

       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.
 . Grant of Patent License. Subject to the terms and conditions of

       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.
 . 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

       (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

           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

           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.
 . 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.
 . 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.
 . 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.
 . 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.
 . 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.

           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.
 . 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.
 . 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.
 . 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.
 . 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.
 . 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.

 		    GNU GENERAL PUBLIC LICENSE
 		       Version 2, June 1991
  Copyright (C) 1989, 1991 Free Software Foundation, Inc.
 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
  Everyone is permitted to copy and distribute verbatim copies
  of this license document, but changing it is not allowed.
 			    Preamble
   The licenses for most software are designed to take away your
 freedom to share and change it.  By contrast, the GNU General Public
 License is intended to guarantee your freedom to share and change free
 software--to make sure the software is free for all its users.  This
 General Public License applies to most of the Free Software
 Foundation's software and to any other program whose authors commit to
 using it.  (Some other Free Software Foundation software is covered by
 the GNU Library General Public License instead.)  You can apply it to
 your programs, too.
   When we speak of free software, we are referring to freedom, not
 price.  Our General Public Licenses are designed to make sure that you
 have the freedom to distribute copies of free software (and charge for
 this service if you wish), that you receive source code or can get it
 if you want it, that you can change the software or use pieces of it
 in new free programs; and that you know you can do these things.
   To protect your rights, we need to make restrictions that forbid
 anyone to deny you these rights or to ask you to surrender the rights.
 These restrictions translate to certain responsibilities for you if you
 distribute copies of the software, or if you modify it.
   For example, if you distribute copies of such a program, whether
 gratis or for a fee, you must give the recipients all the rights that
 you have.  You must make sure that they, too, receive or can get the
 source code.  And you must show them these terms so they know their
 rights.
   We protect your rights with two steps: (1) copyright the software, and
 (2) offer you this license which gives you legal permission to copy,
 distribute and/or modify the software.
   Also, for each author's protection and ours, we want to make certain
 that everyone understands that there is no warranty for this free
 software.  If the software is modified by someone else and passed on, we
 want its recipients to know that what they have is not the original, so
 that any problems introduced by others will not reflect on the original
 authors' reputations.
   Finally, any free program is threatened constantly by software
 patents.  We wish to avoid the danger that redistributors of a free
 program will individually obtain patent licenses, in effect making the
 program proprietary.  To prevent this, we have made it clear that any
 patent must be licensed for everyone's free use or not licensed at all.
   The precise terms and conditions for copying, distribution and
 modification follow.
 		    GNU GENERAL PUBLIC LICENSE
    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
 . This License applies to any program or other work which contains
 a notice placed by the copyright holder saying it may be distributed
 under the terms of this General Public License.  The "Program", below,
 refers to any such program or work, and a "work based on the Program"
 means either the Program or any derivative work under copyright law:
 that is to say, a work containing the Program or a portion of it,
 either verbatim or with modifications and/or translated into another
 language.  (Hereinafter, translation is included without limitation in
 the term "modification".)  Each licensee is addressed as "you".
 Activities other than copying, distribution and modification are not
 covered by this License; they are outside its scope.  The act of
 running the Program is not restricted, and the output from the Program
 is covered only if its contents constitute a work based on the
 Program (independent of having been made by running the Program).
 Whether that is true depends on what the Program does.
 . You may copy and distribute verbatim copies of the Program's
 source code as you receive it, in any medium, provided that you
 conspicuously and appropriately publish on each copy an appropriate
 copyright notice and disclaimer of warranty; keep intact all the
 notices that refer to this License and to the absence of any warranty;
 and give any other recipients of the Program a copy of this License
 along with the Program.
 You may charge a fee for the physical act of transferring a copy, and
 you may at your option offer warranty protection in exchange for a fee.
 . You may modify your copy or copies of the Program or any portion
 of it, thus forming a work based on the Program, and copy and
 distribute such modifications or work under the terms of Section 1
 above, provided that you also meet all of these conditions:
     a) You must cause the modified files to carry prominent notices
     stating that you changed the files and the date of any change.
     b) You must cause any work that you distribute or publish, that in
     whole or in part contains or is derived from the Program or any
     part thereof, to be licensed as a whole at no charge to all third
     parties under the terms of this License.
     c) If the modified program normally reads commands interactively
     when run, you must cause it, when started running for such
     interactive use in the most ordinary way, to print or display an
     announcement including an appropriate copyright notice and a
     notice that there is no warranty (or else, saying that you provide
     a warranty) and that users may redistribute the program under
     these conditions, and telling the user how to view a copy of this
     License.  (Exception: if the Program itself is interactive but
     does not normally print such an announcement, your work based on
     the Program is not required to print an announcement.)
 These requirements apply to the modified work as a whole.  If
 identifiable sections of that work are not derived from the Program,
 and can be reasonably considered independent and separate works in
 themselves, then this License, and its terms, do not apply to those
 sections when you distribute them as separate works.  But when you
 distribute the same sections as part of a whole which is a work based
 on the Program, the distribution of the whole must be on the terms of
 this License, whose permissions for other licensees extend to the
 entire whole, and thus to each and every part regardless of who wrote it.
 Thus, it is not the intent of this section to claim rights or contest
 your rights to work written entirely by you; rather, the intent is to
 exercise the right to control the distribution of derivative or
 collective works based on the Program.
 In addition, mere aggregation of another work not based on the Program
 with the Program (or with a work based on the Program) on a volume of
 a storage or distribution medium does not bring the other work under
 the scope of this License.
 . You may copy and distribute the Program (or a work based on it,
 under Section 2) in object code or executable form under the terms of
 Sections 1 and 2 above provided that you also do one of the following:
     a) Accompany it with the complete corresponding machine-readable
     source code, which must be distributed under the terms of Sections
 and 2 above on a medium customarily used for software interchange; or,
     b) Accompany it with a written offer, valid for at least three
     years, to give any third party, for a charge no more than your
     cost of physically performing source distribution, a complete
     machine-readable copy of the corresponding source code, to be
     distributed under the terms of Sections 1 and 2 above on a medium
     customarily used for software interchange; or,
     c) Accompany it with the information you received as to the offer
     to distribute corresponding source code.  (This alternative is
     allowed only for noncommercial distribution and only if you
     received the program in object code or executable form with such
     an offer, in accord with Subsection b above.)
 The source code for a work means the preferred form of the work for
 making modifications to it.  For an executable work, complete source
 code means all the source code for all modules it contains, plus any
 associated interface definition files, plus the scripts used to
 control compilation and installation of the executable.  However, as a
 special exception, the source code distributed need not include
 anything that is normally distributed (in either source or binary
 form) with the major components (compiler, kernel, and so on) of the
 operating system on which the executable runs, unless that component
 itself accompanies the executable.
 If distribution of executable or object code is made by offering
 access to copy from a designated place, then offering equivalent
 access to copy the source code from the same place counts as
 distribution of the source code, even though third parties are not
 compelled to copy the source along with the object code.
 . You may not copy, modify, sublicense, or distribute the Program
 except as expressly provided under this License.  Any attempt
 otherwise to copy, modify, sublicense or distribute the Program is
 void, and will automatically terminate your rights under this License.
 However, parties who have received copies, or rights, from you under
 this License will not have their licenses terminated so long as such
 parties remain in full compliance.
 . You are not required to accept this License, since you have not
 signed it.  However, nothing else grants you permission to modify or
 distribute the Program or its derivative works.  These actions are
 prohibited by law if you do not accept this License.  Therefore, by
 modifying or distributing the Program (or any work based on the
 Program), you indicate your acceptance of this License to do so, and
 all its terms and conditions for copying, distributing or modifying
 the Program or works based on it.
 . Each time you redistribute the Program (or any work based on the
 Program), the recipient automatically receives a license from the
 original licensor to copy, distribute or modify the Program subject to
 these terms and conditions.  You may not impose any further
 restrictions on the recipients' exercise of the rights granted herein.
 You are not responsible for enforcing compliance by third parties to
 this License.
 . If, as a consequence of a court judgment or allegation of patent
 infringement or for any other reason (not limited to patent issues),
 conditions are imposed on you (whether by court order, agreement or
 otherwise) that contradict the conditions of this License, they do not
 excuse you from the conditions of this License.  If you cannot
 distribute so as to satisfy simultaneously your obligations under this
 License and any other pertinent obligations, then as a consequence you
 may not distribute the Program at all.  For example, if a patent
 license would not permit royalty-free redistribution of the Program by
 all those who receive copies directly or indirectly through you, then
 the only way you could satisfy both it and this License would be to
 refrain entirely from distribution of the Program.
 If any portion of this section is held invalid or unenforceable under
 any particular circumstance, the balance of the section is intended to
 apply and the section as a whole is intended to apply in other
 circumstances.
 It is not the purpose of this section to induce you to infringe any
 patents or other property right claims or to contest validity of any
 such claims; this section has the sole purpose of protecting the
 integrity of the free software distribution system, which is
 implemented by public license practices.  Many people have made
 generous contributions to the wide range of software distributed
 through that system in reliance on consistent application of that
 system; it is up to the author/donor to decide if he or she is willing
 to distribute software through any other system and a licensee cannot
 impose that choice.
 This section is intended to make thoroughly clear what is believed to
 be a consequence of the rest of this License.
 . If the distribution and/or use of the Program is restricted in
 certain countries either by patents or by copyrighted interfaces, the
 original copyright holder who places the Program under this License
 may add an explicit geographical distribution limitation excluding
 those countries, so that distribution is permitted only in or among
 countries not thus excluded.  In such case, this License incorporates
 the limitation as if written in the body of this License.
 . The Free Software Foundation may publish revised and/or new versions
 of the 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 Program
 specifies a version number of this License which applies to it and "any
 later version", you have the option of following the terms and conditions
 either of that version or of any later version published by the Free
 Software Foundation.  If the Program does not specify a version number of
 this License, you may choose any version ever published by the Free Software
 Foundation.
 . If you wish to incorporate parts of the Program into other free
 programs whose distribution conditions are different, write to the author
 to ask for permission.  For software which is copyrighted by the Free
 Software Foundation, write to the Free Software Foundation; we sometimes
 make exceptions for this.  Our decision will be guided by the two goals
 of preserving the free status of all derivatives of our free software and
 of promoting the sharing and reuse of software generally.
 			    NO WARRANTY
 . BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
 REPAIR OR CORRECTION.
 . IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
 POSSIBILITY OF SUCH DAMAGES.
 		     END OF TERMS AND CONDITIONS
 	    How to Apply These Terms to Your New Programs
   If you develop a new program, and you want it to be of the greatest
 possible use to the public, the best way to achieve this is to make it
 free software which everyone can redistribute and change under these terms.
   To do so, attach the following notices to the program.  It is safest
 to attach them to the start of each source file to most effectively
 convey the exclusion of warranty; and each file should have at least
 the "copyright" line and a pointer to where the full notice is found.
     <one line to give the program's name and a brief idea of what it does.>
     Copyright (C) <year>  <name of author>
     This program is free software; you can redistribute it and/or modify
     it under the terms of the GNU General Public License as published by
     the Free Software Foundation; either version 2 of the License, or
     (at your option) any later version.
     This program is distributed in the hope that it will be useful,
     but WITHOUT ANY WARRANTY; without even the implied warranty of
     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
     GNU General Public License for more details.
     You should have received a copy of the GNU General Public License
     along with this program; if not, write to the Free Software
     Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
 Also add information on how to contact you by electronic and paper mail.
 If the program is interactive, make it output a short notice like this
 when it starts in an interactive mode:
     Gnomovision version 69, Copyright (C) year name of author
     Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
     This is free software, and you are welcome to redistribute it
     under certain conditions; type `show c' for details.
 The hypothetical commands `show w' and `show c' should show the appropriate
 parts of the General Public License.  Of course, the commands you use may
 be called something other than `show w' and `show c'; they could even be
 mouse-clicks or menu items--whatever suits your program.
 You should also get your employer (if you work as a programmer) or your
 school, if any, to sign a "copyright disclaimer" for the program, if
 necessary.  Here is a sample; alter the names:
   Yoyodyne, Inc., hereby disclaims all copyright interest in the program
   `Gnomovision' (which makes passes at compilers) written by James Hacker.
   <signature of Ty Coon>, 1 April 1989
   Ty Coon, President of Vice
 This General Public License does not permit incorporating your program into
 proprietary programs.  If your program is a subroutine library, you may
 consider it more useful to permit linking proprietary applications with the
 library.  If this is what you want to do, use the GNU Library General
 Public License instead of this License.

    marks, or logos of any Contributor (except as may be necessary to
    comply with the notice requirements in Section 3.4).
 .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).
 .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.
 .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.
 .7. Conditions
    Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
    in Section 2.1.
 . Responsibilities
 .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.
 .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. 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).
 .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.
 .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.
 . 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.
 . Termination
 .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.
 .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.
 .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.
 . 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.
 . 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.
 . 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.
 . 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.
 . Versions of the License
 .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.
 .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.
 .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).
 .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 https://mozilla.org/MPL/2.0/.
    If it is not possible or desirable to put the notice in a particular
    file, then You may include the notice in a location (such as a LICENSE
    file in a relevant 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 With Secondary Licenses”, as
      defined by the Mozilla Public License, v. 2.0.
