GNU GENERAL PUBLIC LICENSE
                       Version 3, 29 June 2007

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

                            Preamble

  The GNU General Public License is a free, copyleft license for
  software and other kinds of works.

   The licenses for most software and other practical works are designed
  to take away your freedom to share and change the works.  By contrast,
  the GNU General Public License is intended to guarantee your freedom
  to share and change all versions of a program--to make sure it remains
  free software for all its users.  We, the Free Software Foundation, use
  the GNU General Public License for most of our software; it applies
  also to any other work released this way by its authors.  You can apply
  it to your programs, too.

  When we speak of free software, we are referring to freedom, not
  price.  Our General Public Licenses are designed to make sure that you
  have the freedom to distribute copies of free software (and charge for
  them if you wish), that you receive source code or can get it if you
  want it, that you can change the software or use pieces of it in new
  free programs, and that you know you can do these things.

  To protect your rights, we need to prevent others from denying you
  these rights or asking you to surrender the rights.  Therefore, you have
  certain responsibilities if you distribute copies of the software, or if
  you modify it: responsibilities to respect the freedom of others.

  For example, if you distribute copies of such a program, whether
  gratis or for a fee, you must pass on to the recipients the same
  freedoms that you received.  You must make sure that they, too, receive
  or can get the source code.  And you must show them these terms so they
  know their rights.

  Developers that use the GNU GPL protect your rights with two steps:
  (1) assert copyright on the software, and (2) offer you this License
  giving you legal permission to copy, distribute and/or modify it.

  For the developers' and authors' protection, the GPL clearly explains
  that there is no warranty for this free software.  For both users' and
  authors' sake, the GPL requires that modified versions be marked as
  changed, so that their problems will not be attributed erroneously to
  authors of previous versions.

  Some devices are designed to deny users access to install or run
  modified versions of the software inside them, although the manufacturer
  can do so.  This is fundamentally incompatible with the aim of
  protecting users' freedom to change the software.  The systematic
  pattern of such abuse occurs in the area of products for individuals to
  use, which is precisely where it is most unacceptable.  Therefore, we
  have designed this version of the GPL to prohibit the practice for those
  products.  If such problems arise substantially in other domains, we
  stand ready to extend this provision to those domains in future versions
  of the GPL, as needed to protect the freedom of users.

  Finally, every program is threatened constantly by software patents.
  States should not allow patents to restrict development and use of
  software on general-purpose computers, but in those that do, we wish
  to avoid the special danger that patents applied to a free program could
  make it effectively proprietary.  To prevent this, the GPL assures that
  patents cannot be used to render the program non-free.

  The precise terms and conditions for copying, distribution and
  modification follow.

                       TERMS AND CONDITIONS

  0. Definitions.

  "This License" refers to version 3 of the GNU General Public License.

  "Copyright" also means copyright-like laws that apply to other kinds of
  works, such as semiconductor masks.

  "The Program" refers to any copyrightable work licensed under this
  License.  Each licensee is addressed as "you".  "Licensees" and
  "recipients" may be individuals or organizations.

  To "modify" a work means to copy from or adapt all or part of the work
  in a fashion requiring copyright permission, other than the making of an
  exact copy.  The resulting work is called a "modified version" of the
  earlier work or a work "based on" the earlier work.

  A "covered work" means either the unmodified Program or a work based
  on the Program.

  To "propagate" a work means to do anything with it that, without
  permission, would make you directly or secondarily liable for
  infringement under applicable copyright law, except executing it on a
  computer or modifying a private copy.  Propagation includes copying,
  distribution (with or without modification), making available to the
  public, and in some countries other activities as well.

  To "convey" a work means any kind of propagation that enables other
  parties to make or receive copies.  Mere interaction with a user through
  a computer network, with no transfer of a copy, is not conveying.

  An interactive user interface displays "Appropriate Legal Notices"
  to the extent that it includes a convenient and prominently visible
  feature that (1) displays an appropriate copyright notice, and (2)
  tells the user that there is no warranty for the work (except to the
  extent that warranties are provided), that licensees may convey the
  work under this License, and how to view a copy of this License.  If
  the interface presents a list of user commands or options, such as a
  menu, a prominent item in the list meets this criterion.

  1. Source Code.

  The "source code" for a work means the preferred form of the work
  for making modifications to it.  "Object code" means any non-source
  form of a work.

  A "Standard Interface" means an interface that either is an official
  standard defined by a recognized standards body, or, in the case of
  interfaces specified for a particular programming language, one that
  is widely used among developers working in that language.

  The "System Libraries" of an executable work include anything, other
  than the work as a whole, that (a) is included in the normal form of
  packaging a Major Component, but which is not a Major Component
  itself, and (b) serves only to enable use of the 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, or a core library.

  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.

  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, solely for your own personal use, provided that you comply
  with the conditions in Section 3.  You may convey covered works to
  others for the sole purpose of having them make modifications
  exclusively for you, provided that you comply with the conditions in
  Section 3.  Conveying under any other circumstances is permitted
  solely under the conditions stated below.  Sublicensing is not allowed;

  it is not allowed to transfer the responsibilities of Section 3 to
  anyone else.

  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
