     Everyone is permitted to copy and distribute verbatim copies
     of this license document, but changing it is not allowed.

    [This is the first released version of the Lesser GPL.  It also counts
     as the successor of the GNU Library Public License, version 2, hence
     the version number 2.1.]

                                Preamble

      The licenses for most software are designed to take away your
    freedom to share and change it.  By contrast, the GNU General Public
    Licenses are intended to guarantee your freedom to share and change
    free software--to make sure the software is free for all its users.

      This license, the Lesser General Public License, applies to some
    specially designated software packages--typically libraries--of the
    Free Software Foundation and other authors who decide to use it.  You
    can use it too, but we suggest you first think carefully about whether
    this license or the ordinary General Public License is the better
    strategy to use in any particular case, based on the explanations below.

      When we speak of free software, we are referring to freedom of use,
    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 and use pieces of
    it in new free programs; and that you are informed that you can do
    these things.

      To protect your rights, we need to make restrictions that forbid
    distributors to deny you these rights or to ask you to surrender these
    rights.  These restrictions translate to certain responsibilities for
    you if you distribute copies of the library or if you modify it.

      For example, if you distribute copies of the library, whether gratis
    or for a fee, you must give the recipients all the rights that we gave
    you.  You must make sure that they, too, receive or can get the source
    code.  If you link other code with the library, you must provide
    complete object files to the recipients, so that they can relink them
    with the library after making changes to the library and recompiling
    it.  And you must show them these terms so they know their rights.

      We protect your rights with a two-step method: (1) we copyright the
    library, and (2) we offer you this license, which gives you legal
    permission to copy, distribute and/or modify the library.

      To protect each distributor, we want to make it very clear that
    there is no warranty for the free library.  Also, if the library is
    modified by someone else and passed on, the recipients should know
    that what they have is not the original version, so that the original
    author's reputation will not be affected by problems that might be
    introduced by others.

      Finally, software patents pose a constant threat to the existence of
    any free program.  We wish to make sure that a company cannot
    effectively restrict the users of a free program by obtaining a
    restrictive license from a patent holder.  Therefore, we insist that
    any patent license obtained for a version of the library must be
    consistent with the full freedom of use specified in this license.

      Most GNU software, including some libraries, is covered by the
    ordinary GNU General Public License.  This license, the GNU Lesser
    General Public License, applies to certain designated libraries, and
    is quite different from the ordinary General Public License.  We use
    this license for certain libraries in order to permit linking those
    libraries into non-free programs.

      When a program is linked with a library, whether statically or using
    a shared library, the combination of the two is legally speaking a
    combined work, a derivative of the original library.  The ordinary
    General Public License therefore permits such linking only if the
    entire combination fits its criteria of freedom.  The Lesser General
    Public License permits more lax criteria for linking other code with
    the library.

      We call this license the "Lesser" General Public License because it
    does Less to protect the user's freedom than the ordinary General
    Public License.  It also provides other free software developers Less
    of an advantage over competing non-free programs.  These disadvantages
    are the reason we use the ordinary General Public License for many
    libraries.  However, the Lesser license provides advantages in certain
    special circumstances.

      For example, on rare occasions, there may be a special need to
    encourage the widest possible use of a certain library, so that it becomes
    a de-facto standard.  To achieve this, non-free programs must be
    allowed to use the library.  A more frequent case is that a free
    library does the same job as widely used non-free libraries.  In this
    case, there is little to gain by limiting the free library to free
    software only, so we use the Lesser General Public License.

      In other cases, permission to use a particular library in non-free
    programs enables a greater number of people to use a large body of
    free software.  For example, permission to use the GNU C Library in
    non-free programs enables many more people to use the whole GNU
    operating system, as well as its variant, the GNU/Linux operating
    system.

      Although the Lesser General Public License is Less protective of the
    users' freedom, it does ensure that the user of a program that is
    linked with the Library has the freedom and the wherewithal to run
    that program using a modified version of the Library.

      The precise terms and conditions for copying, distribution and
    modification follow.  Pay close attention to the difference between a
    "work based on the library" and a "work that uses the library".  The
    former contains code derived from the library, whereas the latter must
    be combined with the library in order to run.

                      GNU LESSER GENERAL PUBLIC LICENSE
       TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

      0. This License Agreement applies to any software library or other
    program which contains a notice placed by the copyright holder or
    other authorized party saying it may be distributed under the terms of
    this Lesser General Public License (also called "this License").
    Each licensee is addressed as "you".

      A "library" means a collection of software functions and/or data
    prepared so as to be conveniently linked with application programs
    (which use some of those functions and data) to form executables.

      The "Library", below, refers to any such software library or work
    which has been distributed under these terms.  A "work based on the
    Library" means either the Library or any derivative work under
    copyright law: that is to say, a work containing the Library or a
    portion of it, either verbatim or with modifications and/or translated
    straightforwardly into another language.  (Hereinafter, translation is
    included without limitation in the term "modification".)

      "Source code" for a work means the preferred form of the work for
    making modifications to it.  For a library, 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 library.

      Activities other than copying, distribution and modification are not
    covered by this License; they are outside its scope.  The act of
    running a program using the Library is not restricted, and output from
    such a program is covered only if its contents constitute a work based
    on the Library (independent of the use of the Library in a tool for
    writing it).  Whether that is true depends on what the Library does
    and what the program that uses the Library does.

      1. You may copy and distribute verbatim copies of the Library's
    complete 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 distribute a copy of this License along with the
    Library.

      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.

      2. You may modify your copy or copies of the Library or any portion
    of it, thus forming a work based on the Library, 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) The modified work must itself be a software library.

        b) You must cause the files modified to carry prominent notices
        stating that you changed the files and the date of any change.

        c) You must cause the whole of the work to be licensed at no
        charge to all third parties under the terms of this License.

        d) If a facility in the modified Library refers to a function or a
        table of data to be supplied by an application program that uses
        the facility, other than as an argument passed when the facility
        is invoked, then you must make a good faith effort to ensure that,
        in the event an application does not supply such function or
        table, the facility still operates, and performs whatever part of
        its purpose remains meaningful.

        (For example, a function in a library to compute square roots has
        a purpose that is entirely well-defined independent of the
        application.  Therefore, Subsection 2d requires that any
        application-supplied function or table used by this function must
        be optional: if the application does not supply it, the square
        root function must still compute square roots.)

    These requirements apply to the modified work as a whole.  If
    identifiable sections of that work are not derived from the Library,
    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 Library, 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 Library.

    In addition, mere aggregation of another work not based on the Library
    with the Library (or with a work based on the Library) on a volume of
    a storage or distribution medium does not bring the other work under
    the scope of this License.

      3. You may opt to apply the terms of the ordinary GNU General Public
    License instead of this License to a given copy of the Library.  To do
    this, you must alter all the notices that refer to this License, so
    that they refer to the ordinary GNU General Public License, version 2,
    instead of to this License.  (If a newer version than version 2 of the
    ordinary GNU General Public License has appeared, then you can specify
    that version instead if you wish.)  Do not make any other change in
    these notices.

      Once this change is made in a given copy, it is irreversible for
    that copy, so the ordinary GNU General Public License applies to all
    subsequent copies and derivative works made from that copy.

      This option is useful when you wish to copy part of the code of
    the Library into a program that is not a library.

      4. You may copy and distribute the Library (or a portion or
    derivative of it, under Section 2) in object code or executable form
    under the terms of Sections 1 and 2 above provided that you accompany
    it with the complete corresponding machine-readable source code, which
    must be distributed under the terms of Sections 1 and 2 above on a
    medium customarily used for software interchange.

      If distribution of 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 satisfies the requirement to
    distribute the source code, even though third parties are not
    compelled to copy the source along with the object code.

      5. A program that contains no derivative of any portion of the
    Library, but is designed to work with the Library by being compiled or
    linked with it, is called a "work that uses the Library".  Such a
    work, in isolation, is not a derivative work of the Library, and
    therefore falls outside the scope of this License.

      However, linking a "work that uses the Library" with the Library
    creates an executable that is a derivative of the Library (because it
    contains portions of the Library), rather than a "work that uses the
    library".  The executable is therefore covered by this License.
    Section 6 states terms for distribution of such executables.

      When a "work that uses the Library" uses material from a header file
    that is part of the Library, the object code for the work may be a
    derivative work of the Library even though the source code is not.
    Whether this is true is especially significant if the work can be
    linked without the Library, or if the work is itself a library.  The
    threshold for this to be true is not precisely defined by law.

      If such an object file uses only numerical parameters, data
    structure layouts and accessors, and small macros and small inline
    functions (ten lines or less in length), then the use of the object
    file is unrestricted, regardless of whether it is legally a derivative
    work.  (Executables containing this object code plus portions of the
    Library will still fall under Section 6.)

      Otherwise, if the work is a derivative of the Library, you may
    distribute the object code for the work under the terms of Section 6.
    Any executables containing that work also fall under Section 6,
    whether or not they are linked directly with the Library itself.

      6. As an exception to the Sections above, you may also combine or
    link a "work that uses the Library" with the Library to produce a
    work containing portions of the Library, and distribute that work
    under terms of your choice, provided that the terms permit
    modification of the work for the customer's own use and reverse
    engineering for debugging such modifications.

      You must give prominent notice with each copy of the work that the
    Library is used in it and that the Library and its use are covered by
    this License.  You must supply a copy of this License.  If the work
    during execution displays copyright notices, you must include the
    copyright notice for the Library among them, as well as a reference
    directing the user to the copy of this License.  Also, you must do one
    of these things:

        a) Accompany the work with the complete corresponding
        machine-readable source code for the Library including whatever
        changes were used in the work (which must be distributed under
        Sections 1 and 2 above); and, if the work is an executable linked
        with the Library, with the complete machine-readable "work that
        uses the Library", as object code and/or source code, so that the
        user can modify the Library and then relink to produce a modified
        executable containing the modified Library.  (It is understood
        that the user who changes the contents of definitions files in the
        Library will not necessarily be able to recompile the application
        to use the modified definitions.)

        b) Use a suitable shared library mechanism for linking with the
        Library.  A suitable mechanism is one that (1) uses at run time a
        copy of the library already present on the user's computer system,
        rather than copying library functions into the executable, and (2)
        will operate properly with a modified version of the library, if
        the user installs one, as long as the modified version is
        interface-compatible with the version that the work was made with.

        c) Accompany the work with a written offer, valid for at
        least three years, to give the same user the materials
        specified in Subsection 6a, above, for a charge no more
        than the cost of performing this distribution.

        d) If distribution of the work is made by offering access to copy
        from a designated place, offer equivalent access to copy the above
        specified materials from the same place.

        e) Verify that the user has already received a copy of these
        materials or that you have already sent this user a copy.

      For an executable, the required form of the "work that uses the
    Library" must include any data and utility programs needed for
    reproducing the executable from it.  However, as a special exception,
    the materials to be 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.

      It may happen that this requirement contradicts the license
    restrictions of other proprietary libraries that do not normally
    accompany the operating system.  Such a contradiction means you cannot
    use both them and the Library together in an executable that you
    distribute.

      7. 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 not covered by this License, and distribute such a combined
    library, provided that the separate distribution of the work based on
    the Library and of the other library facilities is otherwise
    permitted, and provided that you do these two things:

        a) Accompany the combined library with a copy of the same work
        based on the Library, uncombined with any other library
        facilities.  This must be distributed under the terms of the
        Sections above.

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

      8. You may not copy, modify, sublicense, link with, or distribute
    the Library except as expressly provided under this License.  Any
    attempt otherwise to copy, modify, sublicense, link with, or
    distribute the Library 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.

      9. 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 Library or its derivative works.  These actions are
    prohibited by law if you do not accept this License.  Therefore, by
    modifying or distributing the Library (or any work based on the
    Library), you indicate your acceptance of this License to do so, and
    all its terms and conditions for copying, distributing or modifying
    the Library or works based on it.

      10. Each time you redistribute the Library (or any work based on the
    Library), the recipient automatically receives a license from the
    original licensor to copy, distribute, link with or modify the Library
    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 with
    this License.

      11. 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 Library at all.  For example, if a patent
    license would not permit royalty-free redistribution of the Library 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 Library.

    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.

      12. If the distribution and/or use of the Library is restricted in
    certain countries either by patents or by copyrighted interfaces, the
    original copyright holder who places the Library 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.

      13. The Free Software Foundation may publish revised and/or new
    versions of the 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
    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 Library does not specify a
    license version number, you may choose any version ever published by
    the Free Software Foundation.

      14. If you wish to incorporate parts of the Library into other free
    programs whose distribution conditions are incompatible with these,
    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

      15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
    WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
    EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
    OTHER PARTIES PROVIDE THE LIBRARY "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
    LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
    THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

      16. 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 LIBRARY 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
    LIBRARY (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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), 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 Libraries

      If you develop a new library, and you want it to be of the greatest
    possible use to the public, we recommend making it free software that
    everyone can redistribute and change.  You can do so by permitting
    redistribution under these terms (or, alternatively, under the terms of the
    ordinary General Public License).

      To apply these terms, attach the following notices to the library.  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 library's name and a brief idea of what it does.>
        Copyright (C) <year>  <name of author>

        This library is free software; you can redistribute it and/or
        modify it under the terms of the GNU Lesser General Public
        License as published by the Free Software Foundation; either
        version 2.1 of the License, or (at your option) any later version.

        This library 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
        Lesser General Public License for more details.

        You should have received a copy of the GNU Lesser General Public
        License along with this library; if not, write to the Free Software
        Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA

    Also add information on how to contact you by electronic and paper mail.

    You should also get your employer (if you work as a programmer) or your
    school, if any, to sign a "copyright disclaimer" for the library, if
    necessary.  Here is a sample; alter the names:

      Yoyodyne, Inc., hereby disclaims all copyright interest in the
      library `Frob' (a library for tweaking knobs) written by James Random Hacker.

      <signature of Ty Coon>, 1 April 1990
      Ty Coon, President of Vice

    That's all there is to it!

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:

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

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.

    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:

    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

    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:

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

    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

    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:

    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

    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 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.
