    GNU General Public License
    ==========================

    _Version 3, 29 June 2007_
    _Copyright © 2007 Free Software Foundation, Inc. &lt;<http://fsf.org/>&gt;_

    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
    &lt;<http://www.gnu.org/licenses/>&gt;.

    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
    &lt;<http://www.gnu.org/philosophy/why-not-lgpl.html>&gt;.
