    <acronym>GNU</acronym> General Public License version 3
  </title>
  <para>
    Version 3, 29 June 2007
  </para>
  <para>
    Copyright &copy; 2007 Free Software Foundation, Inc.
    <ulink url="http://fsf.org/">http://fsf.org/</ulink>
  </para>
  <para>
    Everyone is permitted to copy and distribute verbatim copies of this license
    document, but changing it is not allowed.
  </para>
  <bridgehead renderas="sect1">
    Preamble
  </bridgehead>
  <para>
    The <acronym>GNU</acronym> General Public License is a free, copyleft
    license for software and other kinds of works.
  </para>
  <para>
    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
    <acronym>GNU</acronym> General Public License is intended to guarantee your
    freedom to share and change all versions of a program&mdash;to make sure it
    remains free software for all its users.  We, the Free Software Foundation,
    use the <acronym>GNU</acronym> 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.
  </para>
  <para>
    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.
  </para>
  <para>
    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.
  </para>
  <para>
    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.
  </para>
  <para>
    Developers that use the <acronym>GNU</acronym> <acronym>GPL</acronym>
    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.
  </para>
  <para>
    For the developers&rsquo; and authors&rsquo; protection, the
    <acronym>GPL</acronym> clearly explains that there is no warranty for this
    free software.  For both users&rsquo; and authors&rsquo; sake, the
    <acronym>GPL</acronym> requires that modified versions be marked as changed,
    so that their problems will not be attributed erroneously to authors of
    previous versions.
  </para>
  <para>
    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&rsquo;
    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
    <acronym>GPL</acronym> 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 <acronym>GPL</acronym>,
    as needed to protect the freedom of users.
  </para>
  <para>
    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 <acronym>GPL</acronym>
    assures that patents cannot be used to render the program non-free.
  </para>
  <para>
    The precise terms and conditions for copying, distribution and modification
    follow.
  </para>
  <bridgehead>
    TERMS AND CONDITIONS
  </bridgehead>
  <bridgehead renderas="sect1">
    0. Definitions.
  </bridgehead>
  <para>
    &ldquo;This License&rdquo; refers to version 3 of the <acronym>GNU</acronym>
    General Public License.
  </para>
  <para>
    &ldquo;Copyright&rdquo; also means copyright-like laws that apply to other
    kinds of works, such as semiconductor masks.
  </para>
  <para>
    &ldquo;The Program&rdquo; refers to any copyrightable work licensed under
    this License.  Each licensee is addressed as &ldquo;you&rdquo;.
    &ldquo;Licensees&rdquo; and &ldquo;recipients&rdquo; may be individuals or
    organizations.
  </para>
  <para>
    To &ldquo;modify&rdquo; 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 &ldquo;modified
    version&rdquo; of the earlier work or a work &ldquo;based on&rdquo; the
    earlier work.
  </para>
  <para>
    A &ldquo;covered work&rdquo; means either the unmodified Program or a work
    based on the Program.
  </para>
  <para>
    To &ldquo;propagate&rdquo; 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.
  </para>
  <para>
    To &ldquo;convey&rdquo; 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.
  </para>
  <para>
    An interactive user interface displays &ldquo;Appropriate Legal
    Notices&rdquo; 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.
  </para>
  <bridgehead renderas="sect1">
    1. Source Code.
  </bridgehead>
  <para>
    The &ldquo;source code&rdquo; for a work means the preferred form of the
    work for making modifications to it.  &ldquo;Object code&rdquo; means any
    non-source form of a work.
  </para>
  <para>
    A &ldquo;Standard Interface&rdquo; 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.
  </para>
  <para>
    The &ldquo;System Libraries&rdquo; 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 &ldquo;Major Component&rdquo;, 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.
  </para>
  <para>
    The &ldquo;Corresponding Source&rdquo; 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&rsquo;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.
  </para>
  <para>
    The Corresponding Source need not include anything that users can regenerate
    automatically from other parts of the Corresponding Source.
  </para>
  <para>
    The Corresponding Source for a work in source code form is that same work.
  </para>
  <bridgehead renderas="sect1">
    2. Basic Permissions.
  </bridgehead>
  <para>
    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.
  </para>
  <para>
    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.
  </para>

     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

     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

     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.

    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,

    relying&rdquo; means you have actual knowledge that, but for the patent
    license, your conveying the covered work in a country, or your

    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.

    How to Apply These Terms to Your New Programs
  </bridgehead>
  <para>
    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.
  </para>
  <para>
    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
    &ldquo;copyright&rdquo; line and a pointer to where the full notice is
    found.

    Also add information on how to contact you by electronic and paper mail.
  </para>
  <para>
    If the program does terminal interaction, make it output a short notice like
    this when it starts in an interactive mode:
  </para>
  <screen>
<replaceable>program</replaceable> Copyright (C) <replaceable>year</replaceable> <replaceable>name of author</replaceable>

  </screen>
  <para>
    The hypothetical commands &lsquo;<literal>show w</literal>&rsquo; and
    &lsquo;<literal>show c</literal>&rsquo; should show the appropriate parts of
    the General Public License.  Of course, your program&rsquo;s commands might be
    different; for a GUI interface, you would use an &ldquo;about box&rdquo;.
  </para>
  <para>
    You should also get your employer (if you work as a programmer) or school,
    if any, to sign a &ldquo;copyright disclaimer&rdquo; for the program, if
    necessary.  For more information on this, and how to apply and follow the
    <acronym>GNU</acronym> <acronym>GPL</acronym>, see <ulink

  </para>
  <para>
    The <acronym>GNU</acronym> 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 <acronym>GNU</acronym> Lesser General Public License instead of this
    License.  But first, please read <ulink
