# Licenses

## GPL v3

    GNU GENERAL PUBLIC LICENSE
    Version 3, 29 June 2007

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

         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 .

    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:

    {project}  Copyright (C) {year}  {fullname}
    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
    .

    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
    .

## Creative Commons Legal Code

      CC0 1.0 Universal

          CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
          LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES 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 DOCUMENT OR THE INFORMATION OR WORKS
          PROVIDED HEREUNDER, AND 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. Should 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.

         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.
