    SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
    -----------------------------------------------------------
    
    PREAMBLE
    The goals of the Open Font License (OFL) are to stimulate worldwide
    development of collaborative font projects, to support the font creation
    efforts of academic and linguistic communities, and to provide a free and
    open framework in which fonts may be shared and improved in partnership
    with others.
    
    The OFL allows the licensed fonts to be used, studied, modified and
    redistributed freely as long as they are not sold by themselves. The
    fonts, including any derivative works, can be bundled, embedded,
    redistributed and/or sold with any software provided that any reserved
    names are not used by derivative works. The fonts and derivatives,
    however, cannot be released under any other type of license. The
    requirement for fonts to remain under this license does not apply
    to any document created using the fonts or their derivatives.
    
    DEFINITIONS
    "Font Software" refers to the set of files released by the Copyright
    Holder(s) under this license and clearly marked as such. This may
    include source files, build scripts and documentation.
    
    "Reserved Font Name" refers to any names specified as such after the
    copyright statement(s).
    
    "Original Version" refers to the collection of Font Software components as
    distributed by the Copyright Holder(s).
    
    "Modified Version" refers to any derivative made by adding to, deleting,
    or substituting -- in part or in whole -- any of the components of the
    Original Version, by changing formats or by porting the Font Software to a
    new environment.
    
    "Author" refers to any designer, engineer, programmer, technical
    writer or other person who contributed to the Font Software.
    
    PERMISSION & CONDITIONS
    Permission is hereby granted, free of charge, to any person obtaining
    a copy of the Font Software, to use, study, copy, merge, embed, modify,
    redistribute, and sell modified and unmodified copies of the Font
    Software, subject to the following conditions:
    
    1) Neither the Font Software nor any of its individual components,
    in Original or Modified Versions, may be sold by itself.
    
    2) Original or Modified Versions of the Font Software may be bundled,
    redistributed and/or sold with any software, provided that each copy
    contains the above copyright notice and this license. These can be
    included either as stand-alone text files, human-readable headers or
    in the appropriate machine-readable metadata fields within text or
    binary files as long as those fields can be easily viewed by the user.
    
    3) No Modified Version of the Font Software may use the Reserved Font
    Name(s) unless explicit written permission is granted by the corresponding
    Copyright Holder. This restriction only applies to the primary font name as
    presented to the users.
    
    4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
    Software shall not be used to promote, endorse or advertise any
    Modified Version, except to acknowledge the contribution(s) of the
    Copyright Holder(s) and the Author(s) or with their explicit written
    permission.
    
    5) The Font Software, modified or unmodified, in part or in whole,
    must be distributed entirely under this license, and must not be
    distributed under any other license. The requirement for fonts to
    remain under this license does not apply to any document created
    using the Font Software.
    
    TERMINATION

    not met.

         available to the public including in ways that members of the

      k. You means the individual or entity exercising the Licensed Rights

    Section 2 -- Scope.
    
      a. License grant.
    
           1. Subject to the terms and conditions of this Public License,
              the Licensor hereby grants You a worldwide, royalty-free,
              non-sublicensable, non-exclusive, irrevocable license to
              exercise the Licensed Rights in the Licensed Material to:
    
                a. reproduce and Share the Licensed Material, in whole or
                   in part; and
    
                b. produce, reproduce, and Share Adapted Material.
    
           2. Exceptions and Limitations. For the avoidance of doubt, where
              Exceptions and Limitations apply to Your use, this Public
              License does not apply, and You do not need to comply with
              its terms and conditions.
    
           3. Term. The term of this Public License is specified in Section
              6(a).
    
           4. Media and formats; technical modifications allowed. The
              Licensor authorizes You to exercise the Licensed Rights in
              all media and formats whether now known or hereafter created,
              and to make technical modifications necessary to do so. The
              Licensor waives and/or agrees not to assert any right or
              authority to forbid You from making technical modifications
              necessary to exercise the Licensed Rights, including
              technical modifications necessary to circumvent Effective
              Technological Measures. For purposes of this Public License,
              simply making modifications authorized by this Section 2(a)
              (4) never produces Adapted Material.
    
           5. Downstream recipients.
    
                a. Offer from the Licensor -- Licensed Material. Every
                   recipient of the Licensed Material automatically
                   receives an offer from the Licensor to exercise the
                   Licensed Rights under the terms and conditions of this
                   Public License.
    
                b. No downstream restrictions. You may not offer or impose
                   any additional or different terms or conditions on, or
                   apply any Effective Technological Measures to, the
                   Licensed Material if doing so restricts exercise of the
                   Licensed Rights by any recipient of the Licensed
                   Material.
    
           6. No endorsement. Nothing in this Public License constitutes or
              may be construed as permission to assert or imply that You
              are, or that Your use of the Licensed Material is, connected
              with, or sponsored, endorsed, or granted official status by,
              the Licensor or others designated to receive attribution as
              provided in Section 3(a)(1)(A)(i).
    
      b. Other rights.
    
           1. Moral rights, such as the right of integrity, are not
              licensed under this Public License, nor are publicity,
              privacy, and/or other similar personality rights; however, to
              the extent possible, the Licensor waives and/or agrees not to
              assert any such rights held by the Licensor to the limited
              extent necessary to allow You to exercise the Licensed
              Rights, but not otherwise.
    
           2. Patent and trademark rights are not licensed under this
              Public License.
    
           3. To the extent possible, the Licensor waives any right to
              collect royalties from You for the exercise of the Licensed
              Rights, whether directly or through a collecting society
              under any voluntary or waivable statutory or compulsory
              licensing scheme. In all other cases the Licensor expressly
              reserves any right to collect such royalties.
    
    
    Section 3 -- License Conditions.
    
    Your exercise of the Licensed Rights is expressly made subject to the
    following conditions.
    
      a. Attribution.
    
           1. If You Share the Licensed Material (including in modified
              form), You must:
    
                a. retain the following if it is supplied by the Licensor
                   with the Licensed Material:
    
                     i. identification of the creator(s) of the Licensed
                        Material and any others designated to receive
                        attribution, in any reasonable manner requested by
                        the Licensor (including by pseudonym if
                        designated);
    
                    ii. a copyright notice;
    
                   iii. a notice that refers to this Public License;
    
                    iv. a notice that refers to the disclaimer of
                        warranties;
    
                     v. a URI or hyperlink to the Licensed Material to the
                        extent reasonably practicable;
    
                b. indicate if You modified the Licensed Material and
                   retain an indication of any previous modifications; and
    
                c. indicate the Licensed Material is licensed under this
                   Public License, and include the text of, or the URI or
                   hyperlink to, this Public License.
    
           2. You may satisfy the conditions in Section 3(a)(1) in any
              reasonable manner based on the medium, means, and context in
              which You Share the Licensed Material. For example, it may be
              reasonable to satisfy the conditions by providing a URI or
              hyperlink to a resource that includes the required
              information.
    
           3. If requested by the Licensor, You must remove any of the
              information required by Section 3(a)(1)(A) to the extent
              reasonably practicable.
    
           4. If You Share Adapted Material You produce, the Adapter's
              License You apply must not prevent recipients of the Adapted
              Material from complying with this Public License.
    
    
    Section 4 -- Sui Generis Database Rights.
    
    Where the Licensed Rights include Sui Generis Database Rights that
    apply to Your use of the Licensed Material:
    
      a. for the avoidance of doubt, Section 2(a)(1) grants You the right
         to extract, reuse, reproduce, and Share all or a substantial
         portion of the contents of the database;
    
      b. if You include all or a substantial portion of the database
         contents in a database in which You have Sui Generis Database
         Rights, then the database in which You have Sui Generis Database
         Rights (but not its individual contents) is Adapted Material; and
    
      c. You must comply with the conditions in Section 3(a) if You Share
         all or a substantial portion of the contents of the database.
    
    For the avoidance of doubt, this Section 4 supplements and does not
    replace Your obligations under this Public License where the Licensed
    Rights include other Copyright and Similar Rights.
    
    
    Section 5 -- Disclaimer of Warranties and Limitation of Liability.
    
      a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
         EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
         AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
         ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
         IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
         WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
         PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
         ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
         KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
         ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
    
      b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
         TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
         NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
         INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
         COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
         USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
         ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
         DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
         IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
    
      c. The disclaimer of warranties and limitation of liability provided
         above shall be interpreted in a manner that, to the extent
         possible, most closely approximates an absolute disclaimer and
         waiver of all liability.
    
    
    Section 6 -- Term and Termination.
    
      a. This Public License applies for the term of the Copyright and
         Similar Rights licensed here. However, if You fail to comply with
         this Public License, then Your rights under this Public License
         terminate automatically.
    
      b. Where Your right to use the Licensed Material has terminated under
         Section 6(a), it reinstates:
    
           1. automatically as of the date the violation is cured, provided
              it is cured within 30 days of Your discovery of the
              violation; or
    
           2. upon express reinstatement by the Licensor.
    
         For the avoidance of doubt, this Section 6(b) does not affect any
         right the Licensor may have to seek remedies for Your violations
         of this Public License.
    
      c. For the avoidance of doubt, the Licensor may also offer the
         Licensed Material under separate terms or conditions or stop
         distributing the Licensed Material at any time; however, doing so
         will not terminate this Public License.
    
      d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
         License.
    
    
    Section 7 -- Other Terms and Conditions.
    
      a. The Licensor shall not be bound by any additional or different
         terms or conditions communicated by You unless expressly agreed.
    
      b. Any arrangements, understandings, or agreements regarding the
         Licensed Material not stated herein are separate from and
         independent of the terms and conditions of this Public License.
    
    
    Section 8 -- Interpretation.
    
      a. For the avoidance of doubt, this Public License does not, and
         shall not be interpreted to, reduce, limit, restrict, or impose
         conditions on any use of the Licensed Material that could lawfully
         be made without permission under this Public License.
    
      b. To the extent possible, if any provision of this Public License is
         deemed unenforceable, it shall be automatically reformed to the
         minimum extent necessary to make it enforceable. If the provision
         cannot be reformed, it shall be severed from this Public License
         without affecting the enforceability of the remaining terms and
         conditions.
    
      c. No term or condition of this Public License will be waived and no
         failure to comply consented to unless expressly agreed to by the
         Licensor.
    
      d. Nothing in this Public License constitutes or may be interpreted
         as a limitation upon, or waiver of, any privileges and immunities
         that apply to the Licensor or You, including from the legal
         processes of any jurisdiction or authority.

    		   GNU LESSER GENERAL PUBLIC LICENSE
                           Version 3, 29 June 2007
    
     Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
     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 or fewer lines 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 (a) uses at run time
           a copy of the Library already present on the user's computer
           system, and (b) 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.

                        GNU GENERAL PUBLIC LICENSE
                           Version 3, 29 June 2007
    
     Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
     Everyone is permitted to copy and distribute verbatim copies
     of this license document, but changing it is not allowed.
    
                                Preamble
    
      The GNU General Public License is a free, copyleft license for
    software and other kinds of works.
    
      The licenses for most software and other practical works are designed
    to take away your freedom to share and change the works.  By contrast,
    the GNU General Public License is intended to guarantee your freedom to
    share and change all versions of a program--to make sure it remains free
    software for all its users.  We, the Free Software Foundation, use the
    GNU General Public License for most of our software; it applies also to
    any other work released this way by its authors.  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
    them 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 prevent others from denying you
    these rights or asking you to surrender the rights.  Therefore, you have
    certain responsibilities if you distribute copies of the software, or if
    you modify it: responsibilities to respect the freedom of others.
    
      For example, if you distribute copies of such a program, whether
    gratis or for a fee, you must pass on to the recipients the same
    freedoms that you received.  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.
    
      Developers that use the GNU GPL protect your rights with two steps:
    (1) assert copyright on the software, and (2) offer you this License
    giving you legal permission to copy, distribute and/or modify it.
    
      For the developers' and authors' protection, the GPL clearly explains
    that there is no warranty for this free software.  For both users' and
    authors' sake, the GPL requires that modified versions be marked as
    changed, so that their problems will not be attributed erroneously to
    authors of previous versions.
    
      Some devices are designed to deny users access to install or run
    modified versions of the software inside them, although the manufacturer
    can do so.  This is fundamentally incompatible with the aim of
    protecting users' freedom to change the software.  The systematic
    pattern of such abuse occurs in the area of products for individuals to
    use, which is precisely where it is most unacceptable.  Therefore, we
    have designed this version of the GPL to prohibit the practice for those
    products.  If such problems arise substantially in other domains, we
    stand ready to extend this provision to those domains in future versions
    of the GPL, as needed to protect the freedom of users.
    
      Finally, every program is threatened constantly by software patents.
    States should not allow patents to restrict development and use of
    software on general-purpose computers, but in those that do, we wish to
    avoid the special danger that patents applied to a free program could
    make it effectively proprietary.  To prevent this, the GPL assures that
    patents cannot be used to render the program non-free.
    
      The precise terms and conditions for copying, distribution and
    modification follow.
    
                           TERMS AND CONDITIONS
    
      0. Definitions.
    
      "This License" refers to version 3 of the GNU General Public License.
    
      "Copyright" also means copyright-like laws that apply to other kinds of
    works, such as semiconductor masks.
    
      "The Program" refers to any copyrightable work licensed under this
    License.  Each licensee is addressed as "you".  "Licensees" and
    "recipients" may be individuals or organizations.
    
      To "modify" a work means to copy from or adapt all or part of the work
    in a fashion requiring copyright permission, other than the making of an
    exact copy.  The resulting work is called a "modified version" of the
    earlier work or a work "based on" the earlier work.
    
      A "covered work" means either the unmodified Program or a work based
    on the Program.
    
      To "propagate" a work means to do anything with it that, without
    permission, would make you directly or secondarily liable for
    infringement under applicable copyright law, except executing it on a
    computer or modifying a private copy.  Propagation includes copying,
    distribution (with or without modification), making available to the
    public, and in some countries other activities as well.
    
      To "convey" a work means any kind of propagation that enables other
    parties to make or receive copies.  Mere interaction with a user through
    a computer network, with no transfer of a copy, is not conveying.
    
      An interactive user interface displays "Appropriate Legal Notices"
    to the extent that it includes a convenient and prominently visible
    feature that (1) displays an appropriate copyright notice, and (2)
    tells the user that there is no warranty for the work (except to the
    extent that warranties are provided), that licensees may convey the
    work under this License, and how to view a copy of this License.  If
    the interface presents a list of user commands or options, such as a
    menu, a prominent item in the list meets this criterion.
    
      1. Source Code.
    
      The "source code" for a work means the preferred form of the work
    for making modifications to it.  "Object code" means any non-source
    form of a work.
    
      A "Standard Interface" means an interface that either is an official
    standard defined by a recognized standards body, or, in the case of
    interfaces specified for a particular programming language, one that
    is widely used among developers working in that language.
    
      The "System Libraries" of an executable work include anything, other
    than the work as a whole, that (a) is included in the normal form of
    packaging a Major Component, but which is not part of that Major
    Component, and (b) serves only to enable use of the work with that
    Major Component, or to implement a Standard Interface for which an
    implementation is available to the public in source code form.  A
    "Major Component", in this context, means a major essential component
    (kernel, window system, and so on) of the specific operating system
    (if any) on which the executable work runs, or a compiler used to
    produce the work, or an object code interpreter used to run it.
    
      The "Corresponding Source" for a work in object code form means all
    the source code needed to generate, install, and (for an executable
    work) run the object code and to modify the work, including scripts to
    control those activities.  However, it does not include the work's
    System Libraries, or general-purpose tools or generally available free
    programs which are used unmodified in performing those activities but
    which are not part of the work.  For example, Corresponding Source
    includes interface definition files associated with source files for
    the work, and the source code for shared libraries and dynamically
    linked subprograms that the work is specifically designed to require,
    such as by intimate data communication or control flow between those
    subprograms and other parts of the work.
    
      The Corresponding Source need not include anything that users
    can regenerate automatically from other parts of the Corresponding
    Source.
    
      The Corresponding Source for a work in source code form is that
    same work.
    
      2. Basic Permissions.
    
      All rights granted under this License are granted for the term of
    copyright on the Program, and are irrevocable provided the stated
    conditions are met.  This License explicitly affirms your unlimited
    permission to run the unmodified Program.  The output from running a
    covered work is covered by this License only if the output, given its
    content, constitutes a covered work.  This License acknowledges your
    rights of fair use or other equivalent, as provided by copyright law.
    
      You may make, run and propagate covered works that you do not
    convey, without conditions so long as your license otherwise remains
    in force.  You may convey covered works to others for the sole purpose
    of having them make modifications exclusively for you, or provide you
    with facilities for running those works, provided that you comply with
    the terms of this License in conveying all material for which you do
    not control copyright.  Those thus making or running the covered works
    for you must do so exclusively on your behalf, under your direction
    and control, on terms that prohibit them from making any copies of
    your copyrighted material outside their relationship with you.
    
      Conveying under any other circumstances is permitted solely under
    the conditions stated below.  Sublicensing is not allowed; section 10
    makes it unnecessary.
    
      3. Protecting Users' Legal Rights From Anti-Circumvention Law.
    
      No covered work shall be deemed part of an effective technological
    measure under any applicable law fulfilling obligations under article
    11 of the WIPO copyright treaty adopted on 20 December 1996, or
    similar laws prohibiting or restricting circumvention of such
    measures.
    
      When you convey a covered work, you waive any legal power to forbid
    circumvention of technological measures to the extent such circumvention
    is effected by exercising rights under this License with respect to
    the covered work, and you disclaim any intention to limit operation or
    modification of the work as a means of enforcing, against the work's
    users, your or third parties' legal rights to forbid circumvention of
    technological measures.
    
      4. Conveying Verbatim Copies.
    
      You may convey 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;
    keep intact all notices stating that this License and any
    non-permissive terms added in accord with section 7 apply to the code;
    keep intact all notices of the absence of any warranty; and give all
    recipients a copy of this License along with the Program.
    
      You may charge any price or no price for each copy that you convey,
    and you may offer support or warranty protection for a fee.
    
      5. Conveying Modified Source Versions.
    
      You may convey a work based on the Program, or the modifications to
    produce it from the Program, in the form of source code under the
    terms of section 4, provided that you also meet all of these conditions:
    
        a) The work must carry prominent notices stating that you modified
        it, and giving a relevant date.
    
        b) The work must carry prominent notices stating that it is
        released under this License and any conditions added under section
        7.  This requirement modifies the requirement in section 4 to
        "keep intact all notices".
    
        c) You must license the entire work, as a whole, under this
        License to anyone who comes into possession of a copy.  This
        License will therefore apply, along with any applicable section 7
        additional terms, to the whole of the work, and all its parts,
        regardless of how they are packaged.  This License gives no
        permission to license the work in any other way, but it does not
        invalidate such permission if you have separately received it.
    
        d) If the work has interactive user interfaces, each must display
        Appropriate Legal Notices; however, if the Program has interactive
        interfaces that do not display Appropriate Legal Notices, your
        work need not make them do so.
    
      A compilation of a covered work with other separate and independent
    works, which are not by their nature extensions of the covered work,
    and which are not combined with it such as to form a larger program,
    in or on a volume of a storage or distribution medium, is called an
    "aggregate" if the compilation and its resulting copyright are not
    used to limit the access or legal rights of the compilation's users
    beyond what the individual works permit.  Inclusion of a covered work
    in an aggregate does not cause this License to apply to the other
    parts of the aggregate.
    
      6. Conveying Non-Source Forms.
    
      You may convey a covered work in object code form under the terms
    of sections 4 and 5, provided that you also convey the
    machine-readable Corresponding Source under the terms of this License,
    in one of these ways:
    
        a) Convey the object code in, or embodied in, a physical product
        (including a physical distribution medium), accompanied by the
        Corresponding Source fixed on a durable physical medium
        customarily used for software interchange.
    
        b) Convey the object code in, or embodied in, a physical product
        (including a physical distribution medium), accompanied by a
        written offer, valid for at least three years and valid for as
        long as you offer spare parts or customer support for that product
        model, to give anyone who possesses the object code either (1) a
        copy of the Corresponding Source for all the software in the
        product that is covered by this License, on a durable physical
        medium customarily used for software interchange, for a price no
        more than your reasonable cost of physically performing this
        conveying of source, or (2) access to copy the
        Corresponding Source from a network server at no charge.
    
        c) Convey individual copies of the object code with a copy of the
        written offer to provide the Corresponding Source.  This
        alternative is allowed only occasionally and noncommercially, and
        only if you received the object code with such an offer, in accord
        with subsection 6b.
    
        d) Convey the object code by offering access from a designated
        place (gratis or for a charge), and offer equivalent access to the
        Corresponding Source in the same way through the same place at no
        further charge.  You need not require recipients to copy the
        Corresponding Source along with the object code.  If the place to
        copy the object code is a network server, the Corresponding Source
        may be on a different server (operated by you or a third party)
        that supports equivalent copying facilities, provided you maintain
        clear directions next to the object code saying where to find the
        Corresponding Source.  Regardless of what server hosts the
        Corresponding Source, you remain obligated to ensure that it is
        available for as long as needed to satisfy these requirements.
    
        e) Convey the object code using peer-to-peer transmission, provided
        you inform other peers where the object code and Corresponding
        Source of the work are being offered to the general public at no
        charge under subsection 6d.
    
      A separable portion of the object code, whose source code is excluded
    from the Corresponding Source as a System Library, need not be
    included in conveying the object code work.
    
      A "User Product" is either (1) a "consumer product", which means any
    tangible personal property which is normally used for personal, family,
    or household purposes, or (2) anything designed or sold for incorporation
    into a dwelling.  In determining whether a product is a consumer product,
    doubtful cases shall be resolved in favor of coverage.  For a particular
    product received by a particular user, "normally used" refers to a
    typical or common use of that class of product, regardless of the status
    of the particular user or of the way in which the particular user
    actually uses, or expects or is expected to use, the product.  A product
    is a consumer product regardless of whether the product has substantial
    commercial, industrial or non-consumer uses, unless such uses represent
    the only significant mode of use of the product.
    
      "Installation Information" for a User Product means any methods,
    procedures, authorization keys, or other information required to install
    and execute modified versions of a covered work in that User Product from
    a modified version of its Corresponding Source.  The information must
    suffice to ensure that the continued functioning of the modified object
    code is in no case prevented or interfered with solely because
    modification has been made.
    
      If you convey an object code work under this section in, or with, or
    specifically for use in, a User Product, and the conveying occurs as
    part of a transaction in which the right of possession and use of the
    User Product is transferred to the recipient in perpetuity or for a
    fixed term (regardless of how the transaction is characterized), the
    Corresponding Source conveyed under this section must be accompanied
    by the Installation Information.  But this requirement does not apply
    if neither you nor any third party retains the ability to install
    modified object code on the User Product (for example, the work has
    been installed in ROM).
    
      The requirement to provide Installation Information does not include a
    requirement to continue to provide support service, warranty, or updates
    for a work that has been modified or installed by the recipient, or for
    the User Product in which it has been modified or installed.  Access to a
    network may be denied when the modification itself materially and
    adversely affects the operation of the network or violates the rules and
    protocols for communication across the network.
    
      Corresponding Source conveyed, and Installation Information provided,
    in accord with this section must be in a format that is publicly
    documented (and with an implementation available to the public in
    source code form), and must require no special password or key for
    unpacking, reading or copying.
    
      7. Additional Terms.
    
      "Additional permissions" are terms that supplement the terms of this
    License by making exceptions from one or more of its conditions.
    Additional permissions that are applicable to the entire Program shall
    be treated as though they were included in this License, to the extent
    that they are valid under applicable law.  If additional permissions
    apply only to part of the Program, that part may be used separately
    under those permissions, but the entire Program remains governed by
    this License without regard to the additional permissions.
    
      When you convey a copy of a covered work, you may at your option
    remove any additional permissions from that copy, or from any part of
    it.  (Additional permissions may be written to require their own
    removal in certain cases when you modify the work.)  You may place
    additional permissions on material, added by you to a covered work,
    for which you have or can give appropriate copyright permission.
    
      Notwithstanding any other provision of this License, for material you
    add to a covered work, you may (if authorized by the copyright holders of
    that material) supplement the terms of this License with terms:
    
        a) Disclaiming warranty or limiting liability differently from the
        terms of sections 15 and 16 of this License; or
    
        b) Requiring preservation of specified reasonable legal notices or
        author attributions in that material or in the Appropriate Legal
        Notices displayed by works containing it; or
    
        c) Prohibiting misrepresentation of the origin of that material, or
        requiring that modified versions of such material be marked in
        reasonable ways as different from the original version; or
    
        d) Limiting the use for publicity purposes of names of licensors or
        authors of the material; or
    
        e) Declining to grant rights under trademark law for use of some
        trade names, trademarks, or service marks; or
    
        f) Requiring indemnification of licensors and authors of that
        material by anyone who conveys the material (or modified versions of
        it) with contractual assumptions of liability to the recipient, for
        any liability that these contractual assumptions directly impose on
        those licensors and authors.
    
      All other non-permissive additional terms are considered "further
    restrictions" within the meaning of section 10.  If the Program as you
    received it, or any part of it, contains a notice stating that it is
    governed by this License along with a term that is a further
    restriction, you may remove that term.  If a license document contains
    a further restriction but permits relicensing or conveying under this
    License, you may add to a covered work material governed by the terms
    of that license document, provided that the further restriction does
    not survive such relicensing or conveying.
    
      If you add terms to a covered work in accord with this section, you
    must place, in the relevant source files, a statement of the
    additional terms that apply to those files, or a notice indicating
    where to find the applicable terms.
    
      Additional terms, permissive or non-permissive, may be stated in the
    form of a separately written license, or stated as exceptions;
    the above requirements apply either way.
    
      8. Termination.
    
      You may not propagate or modify a covered work except as expressly
    provided under this License.  Any attempt otherwise to propagate or
    modify it is void, and will automatically terminate your rights under
    this License (including any patent licenses granted under the third
    paragraph of section 11).
    
      However, if you cease all violation of this License, then your
    license from a particular copyright holder is reinstated (a)
    provisionally, unless and until the copyright holder explicitly and
    finally terminates your license, and (b) permanently, if the copyright
    holder fails to notify you of the violation by some reasonable means
    prior to 60 days after the cessation.
    
      Moreover, your license from a particular copyright holder is
    reinstated permanently if the copyright holder notifies you of the
    violation by some reasonable means, this is the first time you have
    received notice of violation of this License (for any work) from that
    copyright holder, and you cure the violation prior to 30 days after
    your receipt of the notice.
    
      Termination of your rights under this section does not terminate the
    licenses of parties who have received copies or rights from you under
    this License.  If your rights have been terminated and not permanently
    reinstated, you do not qualify to receive new licenses for the same
    material under section 10.
    
      9. Acceptance Not Required for Having Copies.
    
      You are not required to accept this License in order to receive or
    run a copy of the Program.  Ancillary propagation of a covered work
    occurring solely as a consequence of using peer-to-peer transmission
    to receive a copy likewise does not require acceptance.  However,
    nothing other than this License grants you permission to propagate or
    modify any covered work.  These actions infringe copyright if you do
    not accept this License.  Therefore, by modifying or propagating a
    covered work, you indicate your acceptance of this License to do so.
    
      10. Automatic Licensing of Downstream Recipients.
    
      Each time you convey a covered work, the recipient automatically
    receives a license from the original licensors, to run, modify and
    propagate that work, subject to this License.  You are not responsible
    for enforcing compliance by third parties with this License.
    
      An "entity transaction" is a transaction transferring control of an
    organization, or substantially all assets of one, or subdividing an
    organization, or merging organizations.  If propagation of a covered
    work results from an entity transaction, each party to that
    transaction who receives a copy of the work also receives whatever
    licenses to the work the party's predecessor in interest had or could
    give under the previous paragraph, plus a right to possession of the
    Corresponding Source of the work from the predecessor in interest, if
    the predecessor has it or can get it with reasonable efforts.
    
      You may not impose any further restrictions on the exercise of the
    rights granted or affirmed under this License.  For example, you may
    not impose a license fee, royalty, or other charge for exercise of
    rights granted under this License, and you may not initiate litigation
    (including a cross-claim or counterclaim in a lawsuit) alleging that
    any patent claim is infringed by making, using, selling, offering for
    sale, or importing the Program or any portion of it.
    
      11. Patents.
    
      A "contributor" is a copyright holder who authorizes use under this
    License of the Program or a work on which the Program is based.  The
    work thus licensed is called the contributor's "contributor version".
    
      A contributor's "essential patent claims" are all patent claims
    owned or controlled by the contributor, whether already acquired or
    hereafter acquired, that would be infringed by some manner, permitted
    by this License, of making, using, or selling its contributor version,
    but do not include claims that would be infringed only as a
    consequence of further modification of the contributor version.  For
    purposes of this definition, "control" includes the right to grant
    patent sublicenses in a manner consistent with the requirements of
    this License.
    
      Each contributor grants you a non-exclusive, worldwide, royalty-free
    patent license under the contributor's essential patent claims, to
    make, use, sell, offer for sale, import and otherwise run, modify and
    propagate the contents of its contributor version.
    
      In the following three paragraphs, a "patent license" is any express
    agreement or commitment, however denominated, not to enforce a patent
    (such as an express permission to practice a patent or covenant not to
    sue for patent infringement).  To "grant" such a patent license to a
    party means to make such an agreement or commitment not to enforce a
    patent against the party.
    
      If you convey a covered work, knowingly relying on a patent license,
    and the Corresponding Source of the work is not available for anyone
    to copy, free of charge and under the terms of this License, through a
    publicly available network server or other readily accessible means,
    then you must either (1) cause the Corresponding Source to be so
    available, or (2) arrange to deprive yourself of the benefit of the
    patent license for this particular work, or (3) arrange, in a manner
    consistent with the requirements of this License, to extend the patent
    license to downstream recipients.  "Knowingly relying" means you have
    actual knowledge that, but for the patent license, your conveying the
    covered work in a country, or your recipient's use of the covered work
    in a country, would infringe one or more identifiable patents in that
    country that you have reason to believe are valid.
    
      If, pursuant to or in connection with a single transaction or
    arrangement, you convey, or propagate by procuring conveyance of, a
    covered work, and grant a patent license to some of the parties
    receiving the covered work authorizing them to use, propagate, modify
    or convey a specific copy of the covered work, then the patent license
    you grant is automatically extended to all recipients of the covered
    work and works based on it.
    
      A patent license is "discriminatory" if it does not include within
    the scope of its coverage, prohibits the exercise of, or is
    conditioned on the non-exercise of one or more of the rights that are
    specifically granted under this License.  You may not convey a covered
    work if you are a party to an arrangement with a third party that is
    in the business of distributing software, under which you make payment
    to the third party based on the extent of your activity of conveying
    the work, and under which the third party grants, to any of the
    parties who would receive the covered work from you, a discriminatory
    patent license (a) in connection with copies of the covered work
    conveyed by you (or copies made from those copies), or (b) primarily
    for and in connection with specific products or compilations that
    contain the covered work, unless you entered into that arrangement,
    or that patent license was granted, prior to 28 March 2007.
    
      Nothing in this License shall be construed as excluding or limiting
    any implied license or other defenses to infringement that may
    otherwise be available to you under applicable patent law.
    
      12. No Surrender of Others' Freedom.
    
      If 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 convey a
    covered work so as to satisfy simultaneously your obligations under this
    License and any other pertinent obligations, then as a consequence you may
    not convey it at all.  For example, if you agree to terms that obligate you
    to collect a royalty for further conveying from those to whom you convey
    the Program, the only way you could satisfy both those terms and this
    License would be to refrain entirely from conveying the Program.
    
      13. Use with the GNU Affero General Public License.
    
      Notwithstanding any other provision of this License, you have
    permission to link or combine any covered work with a work licensed
    under version 3 of the GNU Affero General Public License into a single
    combined work, and to convey the resulting work.  The terms of this
    License will continue to apply to the part which is the covered work,
    but the special requirements of the GNU Affero General Public License,
    section 13, concerning interaction through a network will apply to the
    combination as such.
    
      14. Revised Versions of this License.
    
      The Free Software Foundation may publish revised and/or new versions of
    the GNU 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 that a certain numbered version of the GNU General
    Public License "or any later version" applies to it, you have the
    option of following the terms and conditions either of that numbered
    version or of any later version published by the Free Software
    Foundation.  If the Program does not specify a version number of the
    GNU General Public License, you may choose any version ever published
    by the Free Software Foundation.
    
      If the Program specifies that a proxy can decide which future
    versions of the GNU General Public License can be used, that proxy's
    public statement of acceptance of a version permanently authorizes you
    to choose that version for the Program.
    
      Later license versions may give you additional or different
    permissions.  However, no additional obligations are imposed on any
    author or copyright holder as a result of your choosing to follow a
    later version.
    
      15. Disclaimer of Warranty.
    
      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.
    
      16. Limitation of Liability.
    
      IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
    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.
    
      17. Interpretation of Sections 15 and 16.
    
      If the disclaimer of warranty and limitation of liability provided
    above cannot be given local legal effect according to their terms,
    reviewing courts shall apply local law that most closely approximates
    an absolute waiver of all civil liability in connection with the
    Program, unless a warranty or assumption of liability accompanies a
    copy of the Program in return for a fee.
    
                         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
    state 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 3 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, see <http://www.gnu.org/licenses/>.
    
    Also add information on how to contact you by electronic and paper mail.
    
      If the program does terminal interaction, make it output a short
    notice like this when it starts in an interactive mode:
    
        <program>  Copyright (C) <year>  <name of author>
        This program 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, your program's commands
    might be different; for a GUI interface, you would use an "about box".
    
      You should also get your employer (if you work as a programmer) or school,
    if any, to sign a "copyright disclaimer" for the program, if necessary.
    For more information on this, and how to apply and follow the GNU GPL, see
    <http://www.gnu.org/licenses/>.
    
      The GNU 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 Lesser General
    Public License instead of this License.  But first, please read
    <http://www.gnu.org/philosophy/why-not-lgpl.html>.

       TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
    
       1. Definitions.
    
          "License" shall mean the terms and conditions for use, reproduction,
          and distribution as defined by Sections 1 through 9 of this document.
    
          "Licensor" shall mean the copyright owner or entity authorized by
          the copyright owner that is granting the License.
    
          "Legal Entity" shall mean the union of the acting entity and all
          other entities that control, are controlled by, or are under common
          control with that entity. For the purposes of this definition,
          "control" means (i) the power, direct or indirect, to cause the
          direction or management of such entity, whether by contract or
          otherwise, or (ii) ownership of fifty percent (50%) or more of the
          outstanding shares, or (iii) beneficial ownership of such entity.
    
          "You" (or "Your") shall mean an individual or Legal Entity
          exercising permissions granted by this License.
    
          "Source" form shall mean the preferred form for making modifications,
          including but not limited to software source code, documentation
          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
          communication on electronic mailing lists, source code control systems,
          and issue tracking systems that are managed by, or on behalf of, the
          Licensor for the purpose of discussing and improving the Work, but
          excluding communication that is conspicuously marked or otherwise
          designated in writing by the copyright owner as "Not a Contribution."
    
          "Contributor" shall mean Licensor and any individual or Legal Entity
          on behalf of whom a Contribution has been received by Licensor and
          subsequently incorporated within the Work.
    
       2. Grant of Copyright License. Subject to the terms and conditions of
          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
          copyright license to reproduce, prepare Derivative Works of,
          publicly display, publicly perform, sublicense, and distribute the
          Work and such Derivative Works in Source or Object form.
    
       3. Grant of Patent License. Subject to the terms and conditions of
          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
          (except as stated in this section) patent license to make, have made,
          use, offer to sell, sell, import, and otherwise transfer the Work,
          where such license applies only to those patent claims licensable
          by such Contributor that are necessarily infringed by their
          Contribution(s) alone or by combination of their Contribution(s)
          with the Work to which such Contribution(s) was submitted. If You
          institute patent litigation against any entity (including a
          cross-claim or counterclaim in a lawsuit) alleging that the Work
          or a Contribution incorporated within the Work constitutes direct
          or contributory patent infringement, then any patent licenses
          granted to You under this License for that Work shall terminate
          as of the date such litigation is filed.
    
       4. Redistribution. You may reproduce and distribute copies of the
          Work or Derivative Works thereof in any medium, with or without
          modifications, and in Source or Object form, provided that You
          meet the following conditions:
    
          (a) You must give any other recipients of the Work or
              Derivative Works a copy of this License; and
    
          (b) You must cause any modified files to carry prominent notices
              stating that You changed the files; and
    
          (c) You must retain, in the Source form of any Derivative Works
              that You distribute, all copyright, patent, trademark, and
              attribution notices from the Source form of the Work,
              excluding those notices that do not pertain to any part of
              the Derivative Works; and
    
          (d) If the Work includes a "NOTICE" text file as part of its
              distribution, then any Derivative Works that You distribute must
              include a readable copy of the attribution notices contained
              within such NOTICE file, excluding those notices that do not
              pertain to any part of the Derivative Works, in at least one
              of the following places: within a NOTICE text file distributed
              as part of the Derivative Works; within the Source form or
              documentation, if provided along with the Derivative Works; or,
              within a display generated by the Derivative Works, if and
              wherever such third-party notices normally appear. The contents
              of the NOTICE file are for informational purposes only and
              do not modify the License. You may add Your own attribution
              notices within Derivative Works that You distribute, alongside
              or as an addendum to the NOTICE text from the Work, provided
              that such additional attribution notices cannot be construed
              as modifying the License.
    
          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.

    CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT

    NOT CREATE AN ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS
    PROVIDES THIS INFORMATION ON AN "AS-IS" BASIS. CREATIVE
    COMMONS MAKES NO WARRANTIES REGARDING THE USE OF THIS

    DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM THE USE OF
    THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
    HEREUNDER.
    
    Statement of Purpose
    The laws of most jurisdictions throughout the world
    automatically confer exclusive Copyright and Related Rights
    (defined below) upon the creator and subsequent owner(s) (each
    and all, an "owner") of an original work of authorship and/or
    a database (each, a "Work").
    Certain owners wish to permanently relinquish those rights
    to a Work for the purpose of contributing to a commons of
    creative, cultural and scientific works ("Commons") that the
    public can reliably and without fear of later claims of
    infringement build upon, modify, incorporate in other works,
    reuse and redistribute as freely as possible in any form
    whatsoever and for any purposes, including without limitation
    commercial purposes. These owners may contribute to the
    Commons to promote the ideal of a free culture and the further
    production of creative, cultural and scientific works, or to
    gain reputation or greater distribution for their Work in part
    through the use and efforts of others.
    For these and/or other purposes and motivations, and
    without any expectation of additional consideration or
    compensation, the person associating CC0 with a Work (the
    "Affirmer"), to the extent that he or she is an owner of
    Copyright and Related Rights in the Work, voluntarily elects
    to apply CC0 to the Work and publicly distribute the Work
    under its terms, with knowledge of his or her Copyright and
    Related Rights in the Work and the meaning and intended legal
    effect of CC0 on those rights.
    
    1. Copyright and Related Rights.
    A Work made available under CC0 may be protected by
    copyright and related or neighboring rights ("Copyright and
    Related Rights"). Copyright and Related Rights include, but
    are not limited to, the following:
    
    i. the right to reproduce, adapt, distribute, perform, display,
    communicate, and translate a Work;
    ii. moral rights retained by the original author(s) and/or performer(s);
    iii. publicity and privacy rights pertaining to a person's
    image or likeness depicted in a Work;
    iv. rights protecting against unfair competition in regards to a Work,
    subject to the limitations in paragraph 4(a), below;
    v. rights protecting the extraction, dissemination, use and
    reuse of data in a Work;
    vi. database rights (such as those arising under Directive 96/9/EC
    of the European Parliament and of the Council of 11 March 1996
    on the legal protection of databases, and under any national
    implementation thereof, including any amended or successor
    version of such directive); and
    vii. other similar, equivalent or corresponding rights
    throughout the world based on applicable law or treaty,
    and any national implementations thereof.
    
    2. Waiver.
    To the greatest extent permitted by, but not in contravention of,
    applicable law, Affirmer hereby overtly, fully, permanently,
    irrevocably and unconditionally waives, abandons, and surrenders
    all of Affirmer's Copyright and Related Rights and associated
    claims and causes of action, whether now known or unknown (including
    existing as well as future claims and causes of action), in the
    Work (i) in all territories worldwide, (ii) for the maximum
    duration provided by applicable law or treaty (including future
    time extensions), (iii) in any current or future medium and for
    any number of copies, and (iv) for any purpose whatsoever,
    including without limitation commercial, advertising or promotional
    purposes (the "Waiver"). Affirmer makes the Waiver for the benefit
    of each member of the public at large and to the detriment of Affirmer's
    heirs and successors, fully intending that such Waiver shall not be
    subject to revocation, rescission, cancellation, termination, or any
    other legal or equitable action to disrupt the quiet enjoyment of the
    Work by the public as contemplated by Affirmer's express Statement
    of Purpose.
    
    3. Public License Fallback.
    hould any part of the Waiver for any reason be judged legally invalid
    or ineffective under applicable law, then the Waiver shall be preserved
    to the maximum extent permitted taking into account Affirmer's express
    Statement of Purpose. In addition, to the extent the Waiver is so
    judged Affirmer hereby grants to each affected person a royalty-free,
    non transferable, non sublicensable, non exclusive, irrevocable and
    unconditional license to exercise Affirmer's Copyright and Related
    Rights in the Work (i) in all territories worldwide, (ii) for the
    maximum duration provided by applicable law or treaty (including future
    time extensions), (iii) in any current or future medium and for any
    number of copies, and (iv) for any purpose whatsoever, including without
    limitation commercial, advertising or promotional purposes (the "License").
    The License shall be deemed effective as of the date CC0 was applied by
    Affirmer to the Work. Should any part of the License for any reason be
    judged legally invalid or ineffective under applicable law, such partial
    invalidity or ineffectiveness shall not invalidate the remainder of the
    License, and in such case Affirmer hereby affirms that he or she will
    not (i) exercise any of his or her remaining Copyright and Related
    Rights in the Work or (ii) assert any associated claims and causes
    of action with respect to the Work, in either case contrary to
    Affirmer's express Statement of Purpose.
    
    4. Limitations and Disclaimers.
    
    a. No trademark or patent rights held by Affirmer are waived, abandoned,
    surrendered, licensed or otherwise affected by this document.
    b. Affirmer offers the Work as-is and makes no representations or
    warranties of any kind concerning the Work, express, implied, statutory
    or otherwise, including without limitation warranties of title,
    merchantability, fitness for a particular purpose, non infringement,
    or the absence of latent or other defects, accuracy, or the present
    or absence of errors, whether or not discoverable, all to the greatest
    extent permissible under applicable law.
    c. Affirmer disclaims responsibility for clearing rights of other
    persons that may apply to the Work or any use thereof, including
    without limitation any person's Copyright and Related Rights in the
    Work. Further, Affirmer disclaims responsibility for obtaining any
    necessary consents, permissions or other rights required for any use
    of the Work.
    d. Affirmer understands and acknowledges that Creative Commons is not
    a party to this document and has no duty or obligation with respect
    to this CC0 or use of the Work.

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

    2.2. Effective Date
    
    The licenses granted in Section 2.1 with respect to any Contribution
    become effective for each Contribution on the date the Contributor first
    distributes such Contribution.
    
    2.3. Limitations on Grant Scope
    
    The licenses granted in this Section 2 are the only rights granted under
    this License. No additional rights or licenses will be implied from the
    distribution or licensing of Covered Software under this License.
    Notwithstanding Section 2.1(b) above, no patent license is granted by a
    Contributor:
    
    (a) for any code that a Contributor has removed from Covered Software;
        or
    
    (b) for infringements caused by: (i) Your and any other third party's
        modifications of Covered Software, or (ii) the combination of its
        Contributions with other software (except as part of its Contributor
        Version); or
    
    (c) under Patent Claims infringed by Covered Software in the absence of
        its Contributions.
    
    This License does not grant any rights in the trademarks, service marks,
    or logos of any Contributor (except as may be necessary to comply with
    the notice requirements in Section 3.4).
    
    2.4. Subsequent Licenses
    
    No Contributor makes additional grants as a result of Your choice to
    distribute the Covered Software under a subsequent version of this
    License (see Section 10.2) or under the terms of a Secondary License (if
    permitted under the terms of Section 3.3).
    
    2.5. Representation
    
    Each Contributor represents that the Contributor believes its
    Contributions are its original creation(s) or it has sufficient rights
    to grant the rights to its Contributions conveyed by this License.
    
    2.6. Fair Use
    
    This License is not intended to limit any rights You have under
    applicable copyright doctrines of fair use, fair dealing, or other
    equivalents.
    
    2.7. Conditions
    
    Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
    in Section 2.1.
    
    3. Responsibilities
    -------------------
    
    3.1. Distribution of Source Form
    
    All distribution of Covered Software in Source Code Form, including any
    Modifications that You create or to which You contribute, must be under
    the terms of this License. You must inform recipients that the Source
    Code Form of the Covered Software is governed by the terms of this
    License, and how they can obtain a copy of this License. You may not
    attempt to alter or restrict the recipients' rights in the Source Code
    Form.
    
    3.2. Distribution of Executable Form
    
    If You distribute Covered Software in Executable Form then:
    
    (a) such Covered Software must also be made available in Source Code
        Form, as described in Section 3.1, and You must inform recipients of
        the Executable Form how they can obtain a copy of such Source Code
        Form by reasonable means in a timely manner, at a charge no more
        than the cost of distribution to the recipient; and
    
    (b) You may distribute such Executable Form under the terms of this
        License, or sublicense it under different terms, provided that the
        license for the Executable Form does not attempt to limit or alter
        the recipients' rights in the Source Code Form under this License.
    
    3.3. Distribution of a Larger Work
    
    You may create and distribute a Larger Work under terms of Your choice,
    provided that You also comply with the requirements of this License for
    the Covered Software. If the Larger Work is a combination of Covered
    Software with a work governed by one or more Secondary Licenses, and the
    Covered Software is not Incompatible With Secondary Licenses, this
    License permits You to additionally distribute such Covered Software
    under the terms of such Secondary License(s), so that the recipient of
    the Larger Work may, at their option, further distribute the Covered
    Software under the terms of either this License or such Secondary
    License(s).
    
    3.4. Notices
    
    You may not remove or alter the substance of any license notices
    (including copyright notices, patent notices, disclaimers of warranty,
    or limitations of liability) contained within the Source Code Form of
    the Covered Software, except that You may alter any license notices to
    the extent required to remedy known factual inaccuracies.
    
    3.5. Application of Additional Terms
    
    You may choose to offer, and to charge a fee for, warranty, support,
    indemnity or liability obligations to one or more recipients of Covered
    Software. However, You may do so only on Your own behalf, and not on
    behalf of any Contributor. You must make it absolutely clear that any
    such warranty, support, indemnity, or liability obligation is offered by
    You alone, and You hereby agree to indemnify every Contributor for any
    liability incurred by such Contributor as a result of warranty, support,
    indemnity or liability terms You offer. You may include additional
    disclaimers of warranty and limitations of liability specific to any
    jurisdiction.
    
    4. Inability to Comply Due to Statute or Regulation
    ---------------------------------------------------
    
    If it is impossible for You to comply with any of the terms of this
    License with respect to some or all of the Covered Software due to
    statute, judicial order, or regulation then You must: (a) comply with
    the terms of this License to the maximum extent possible; and (b)
    describe the limitations and the code they affect. Such description must
    be placed in a text file included with all distributions of the Covered
    Software under this License. Except to the extent prohibited by statute
    or regulation, such description must be sufficiently detailed for a
    recipient of ordinary skill to be able to understand it.
    
    5. Termination
    --------------
    
    5.1. The rights granted under this License will terminate automatically
    if You fail to comply with any of its terms. However, if You become
    compliant, then the rights granted under this License from a particular
    Contributor are reinstated (a) provisionally, unless and until such
    Contributor explicitly and finally terminates Your grants, and (b) on an
    ongoing basis, if such Contributor fails to notify You of the
    non-compliance by some reasonable means prior to 60 days after You have
    come back into compliance. Moreover, Your grants from a particular

    SIL OPEN FONT LICENSE
    
    Version 1.1 - 26 February 2007
    
    PREAMBLE
    The goals of the Open Font License (OFL) are to stimulate worldwide
    development of collaborative font projects, to support the font creation
    efforts of academic and linguistic communities, and to provide a free and
    open framework in which fonts may be shared and improved in partnership
    with others.
    
    The OFL allows the licensed fonts to be used, studied, modified and
    redistributed freely as long as they are not sold by themselves. The
    fonts, including any derivative works, can be bundled, embedded,
    redistributed and/or sold with any software provided that any reserved
    names are not used by derivative works. The fonts and derivatives,
    however, cannot be released under any other type of license. The
    requirement for fonts to remain under this license does not apply
    to any document created using the fonts or their derivatives.
    
    DEFINITIONS
    "Font Software" refers to the set of files released by the Copyright
    Holder(s) under this license and clearly marked as such. This may
    include source files, build scripts and documentation.
    
    "Reserved Font Name" refers to any names specified as such after the
    copyright statement(s).
    
    "Original Version" refers to the collection of Font Software components as
    distributed by the Copyright Holder(s).
    
    "Modified Version" refers to any derivative made by adding to, deleting,
    or substituting — in part or in whole — any of the components of the
    Original Version, by changing formats or by porting the Font Software to a
    new environment.
    
    "Author" refers to any designer, engineer, programmer, technical
    writer or other person who contributed to the Font Software.
    
    PERMISSION & CONDITIONS
    Permission is hereby granted, free of charge, to any person obtaining
    a copy of the Font Software, to use, study, copy, merge, embed, modify,
    redistribute, and sell modified and unmodified copies of the Font
    Software, subject to the following conditions:
    
    1) Neither the Font Software nor any of its individual components,
    in Original or Modified Versions, may be sold by itself.
    
    2) Original or Modified Versions of the Font Software may be bundled,
    redistributed and/or sold with any software, provided that each copy
    contains the above copyright notice and this license. These can be
    included either as stand-alone text files, human-readable headers or
    in the appropriate machine-readable metadata fields within text or
    binary files as long as those fields can be easily viewed by the user.
    
    3) No Modified Version of the Font Software may use the Reserved Font
    Name(s) unless explicit written permission is granted by the corresponding
    Copyright Holder. This restriction only applies to the primary font name as
    presented to the users.
    
    4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
    Software shall not be used to promote, endorse or advertise any
    Modified Version, except to acknowledge the contribution(s) of the
    Copyright Holder(s) and the Author(s) or with their explicit written
    permission.
    
    5) The Font Software, modified or unmodified, in part or in whole,
    must be distributed entirely under this license, and must not be
    distributed under any other license. The requirement for fonts to
    remain under this license does not apply to any document created
    using the Font Software.
    
    TERMINATION
    This license becomes null and void if any of the above conditions are
    not met.
    
    DISCLAIMER
    THE FONT SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND,
    EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTIES OF
    MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT
    OF COPYRIGHT, PATENT, TRADEMARK, OR OTHER RIGHT. IN NO EVENT SHALL THE
    COPYRIGHT HOLDER BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY,
    INCLUDING ANY GENERAL, SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL
    DAMAGES, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING
    FROM, OUT OF THE USE OR INABILITY TO USE THE FONT SOFTWARE OR FROM
    OTHER DEALINGS IN THE FONT SOFTWARE.

    Use, reproduction, and distribution of this software is permitted.
    Any copy of this software, whether in its original form or modified,
    must include both the above copyright notice and the following
    paragraphs.
    
    Nara Institute of Science and Technology (NAIST),
    the copyright holders, disclaims all warranties with regard to this
    software, including all implied warranties of merchantability and
    fitness, in no event shall NAIST be liable for
    any special, indirect or consequential damages or any damages
    whatsoever resulting from loss of use, data or profits, whether in an
    action of contract, negligence or other tortuous action, arising out
    of or in connection with the use or performance of this software.
    
    A large portion of the dictionary entries
    originate from ICOT Free Software.  The following conditions for ICOT
    Free Software applies to the current dictionary as well.
    
    Each User may also freely distribute the Program, whether in its
    original form or modified, to any third party or parties, PROVIDED
    that the provisions of Section 3 ("NO WARRANTY") will ALWAYS appear
    on, or be attached to, the Program, which is distributed substantially
    in the same form as set out herein and that such intended
    distribution, if actually made, will neither violate or otherwise
    contravene any of the laws and regulations of the countries having
    jurisdiction over the User or the intended distribution itself.
    
    NO WARRANTY
    
    The program was produced on an experimental basis in the course of the
    research and development conducted during the project and is provided
    to users as so produced on an experimental basis.  Accordingly, the
    program is provided without any warranty whatsoever, whether express,
    implied, statutory or otherwise.  The term "warranty" used herein
    includes, but is not limited to, any warranty of the quality,
    performance, merchantability and fitness for a particular purpose of
    the program and the nonexistence of any infringement or violation of
    any right of any third party.
    
    Each user of the program will agree and understand, and be deemed to
    have agreed and understood, that there is no warranty whatsoever for
    the program and, accordingly, the entire risk arising from or
    otherwise connected with the program is assumed by the user.
    
    Therefore, neither ICOT, the copyright holder, or any other
    organization that participated in or was otherwise related to the
    development of the program and their respective officials, directors,
    officers and other employees shall be held liable for any and all
    damages, including, without limitation, general, special, incidental
    and consequential damages, arising out of or otherwise in connection
    with the use or inability to use the program or any product, material
    or result produced or otherwise obtained by using the program,
    regardless of whether they have been advised of, or otherwise had
    knowledge of, the possibility of such damages at any time during the
    project or thereafter.  Each user will be deemed to have agreed to the
    foregoing by his or her commencement of use of the program.  The term
    "use" as used herein includes, but is not limited to, the use,
    modification, copying and distribution of the program and the
    production of secondary products from the program.
    
    In the case where the program, whether in its original form or
    modified, was distributed or delivered to or received by a user from
    any person, organization or entity other than ICOT, unless it makes or
    grants independently of ICOT any specific warranty to the user in
    writing, such person, organization or entity, will also be exempted
    from and not be held liable to the user for any such damages as noted
    above as far as the program is concerned.

    ### Time Zone Database
    
    ```
      ICU uses the public domain data and code derived from Time Zone
    Database for its time zone support. The ownership of the TZ database
    is explained in BCP 175: Procedure for Maintaining the Time Zone
    Database section 7.
    
    The TZ database itself is not an IETF Contribution or an IETF
    document.  Rather it is a pre-existing and regularly updated work
    that is in the public domain, and is intended to remain in the
    public domain.  Therefore, BCPs 78 [RFC5378] and 79 [RFC3979] do
    not apply to the TZ Database or contributions that individuals make
    to it.  Should any claims be made and substantiated against the TZ
    Database, the organization that is providing the IANA
    Considerations defined in this RFC, under the memorandum of
    understanding with the IETF, currently ICANN, may act in accordance
    with all competent court orders.  No ownership claims will be made
    by ICANN or the IETF Trust on the database or the code.  Any person
    making a contribution to the database or code waives all rights to
    future claims in that contribution or in the TZ Database.
