                      GNU GENERAL PUBLIC LICENSE
                         Version <span class="number">3</span><span class="operator">,</span> <span class="number">29</span> June <span class="number">2007</span>

   Copyright (C) <span class="number">2007</span> Free Software Foundation<span class="operator">,</span> Inc<span class="operator">.</span> <span class="operator">&lt;</span>http:<span class="comment">//fsf.org/&gt;</span>
   Everyone is permitted to copy and distribute verbatim copies
   of <span class="keyword">this</span> license document<span class="operator">,</span> but changing it is <span class="keyword">not</span> allowed<span class="operator">.</span>

                              Preamble

    The GNU General Public License is a free<span class="operator">,</span> copyleft license <span class="keyword">for</span>
  software and other kinds of works<span class="operator">.</span>

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

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

    To protect your rights<span class="operator">,</span> we need to prevent others from denying you
  these rights <span class="keyword">or</span> asking you to surrender the rights<span class="operator">.</span>  Therefore<span class="operator">,</span> you have
  certain responsibilities <span class="keyword">if</span> you distribute copies of the software<span class="operator">,</span> <span class="keyword">or</span> <span class="keyword">if</span>
  you modify it: responsibilities to respect the freedom of others<span class="operator">.</span>

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

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

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

    Some devices are designed to deny users access to install <span class="keyword">or</span> run
  modified versions of the software inside them<span class="operator">,</span> although the manufacturer
  can <span class="keyword">do</span> so<span class="operator">.</span>  This is fundamentally incompatible with the aim of
  protecting users<span class="char">' 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.

    &quot;This License&quot; refers to version 3 of the GNU General Public License.

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

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

    To &quot;modify&quot; 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 &quot;modified version&quot; of the
  earlier work or a work &quot;based on&quot; the earlier work.

    A &quot;covered work&quot; means either the unmodified Program or a work based
  on the Program.

    To &quot;propagate&quot; 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 &quot;convey&quot; 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 &quot;Appropriate Legal Notices&quot;
  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 &quot;source code&quot; for a work means the preferred form of the work
  for making modifications to it.  &quot;Object code&quot; means any non-source
  form of a work.

    A &quot;Standard Interface&quot; 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 &quot;System Libraries&quot; 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
  &quot;Major Component&quot;, 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 &quot;Corresponding Source&quot; 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'</span>s

  copyright on the Program<span class="operator">,</span> and are irrevocable provided the stated
  conditions are met<span class="operator">.</span>  This License explicitly affirms your unlimited

    <span class="number">3.</span> Protecting Users<span class="char">' 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'</span>s
  users<span class="operator">,</span> your <span class="keyword">or</span> third parties<span class="char">' legal rights to forbid circumvention of
  technological measures.

    4. Conveying Verbatim Copies.

    You may convey verbatim copies of the Program'</span>s source code as you
  receive it<span class="operator">,</span> in any medium<span class="operator">,</span> provided that you conspicuously and
  appropriately publish on each copy an appropriate copyright notice;
  keep intact all notices stating that <span class="keyword">this</span> License and any
  non<span class="operator">-</span>permissive terms added in accord with section <span class="number">7</span> apply to the code;
  keep intact all notices of the absence of any warranty; and give all
  recipients a copy of <span class="keyword">this</span> License along with the Program<span class="operator">.</span>

    You may charge any price <span class="keyword">or</span> no price <span class="keyword">for</span> each copy that you convey<span class="operator">,</span>
  and you may offer support <span class="keyword">or</span> warranty protection <span class="keyword">for</span> a fee<span class="operator">.</span>

    <span class="number">5.</span> Conveying Modified Source Versions<span class="operator">.</span>

    You may convey a work based on the Program<span class="operator">,</span> <span class="keyword">or</span> the modifications to
  produce it from the Program<span class="operator">,</span> in the form of source code under the
  terms of section <span class="number">4</span><span class="operator">,</span> provided that you also meet all of these conditions:

      a) The work must carry prominent notices stating that you modified
      it<span class="operator">,</span> and giving a relevant date<span class="operator">.</span>

      b) The work must carry prominent notices stating that it is
      released under <span class="keyword">this</span> License and any conditions added under section
      <span class="number">7.</span>  This requirement modifies the requirement in section <span class="number">4</span> to
      <span class="string">&quot;keep intact all notices&quot;</span><span class="operator">.</span>

      c) You must license the entire work<span class="operator">,</span> as a whole<span class="operator">,</span> under <span class="keyword">this</span>
      License to anyone who comes into possession of a copy<span class="operator">.</span>  This

      additional terms<span class="operator">,</span> to the whole of the work<span class="operator">,</span> and all its parts<span class="operator">,</span>
      regardless of how they are packaged<span class="operator">.</span>  This License gives no
      permission to license the work in any other way<span class="operator">,</span> but it does <span class="keyword">not</span>
      invalidate such permission <span class="keyword">if</span> you have separately received it<span class="operator">.</span>

      d) If the work has interactive user interfaces<span class="operator">,</span> each must display
      Appropriate Legal Notices; however<span class="operator">,</span> <span class="keyword">if</span> the Program has interactive
      interfaces that <span class="keyword">do</span> <span class="keyword">not</span> display Appropriate Legal Notices<span class="operator">,</span> your

    A compilation of a covered work with other separate and independent
  works<span class="operator">,</span> which are <span class="keyword">not</span> by their nature extensions of the covered work<span class="operator">,</span>
  and which are <span class="keyword">not</span> combined with it such as to form a larger program<span class="operator">,</span>
  in <span class="keyword">or</span> on a volume of a storage <span class="keyword">or</span> distribution medium<span class="operator">,</span> is called an
  <span class="string">&quot;aggregate&quot;</span> <span class="keyword">if</span> the compilation and its resulting copyright are <span class="keyword">not</span>
  used to limit the access <span class="keyword">or</span> legal rights of the compilation<span class="char">'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 &quot;User Product&quot; is either (1) a &quot;consumer product&quot;, 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, &quot;normally used&quot; 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.

    &quot;Installation Information&quot; 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.

    &quot;Additional permissions&quot; 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 &quot;further
  restrictions&quot; 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 &quot;entity transaction&quot; 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'</span>s predecessor in interest had <span class="keyword">or</span> could
  give under the previous paragraph<span class="operator">,</span> plus a right to possession of the
  Corresponding Source of the work from the predecessor in interest<span class="operator">,</span> <span class="keyword">if</span>
  the predecessor has it <span class="keyword">or</span> can get it with reasonable efforts<span class="operator">.</span>

    You may <span class="keyword">not</span> impose any further restrictions on the exercise of the
  rights granted <span class="keyword">or</span> affirmed under <span class="keyword">this</span> License<span class="operator">.</span>  For example<span class="operator">,</span> you may
  <span class="keyword">not</span> impose a license fee<span class="operator">,</span> royalty<span class="operator">,</span> <span class="keyword">or</span> other charge <span class="keyword">for</span> exercise of
  rights granted under <span class="keyword">this</span> License<span class="operator">,</span> and you may <span class="keyword">not</span> initiate litigation
  (including a cross<span class="operator">-</span>claim <span class="keyword">or</span> counterclaim in a lawsuit) alleging that
  any patent claim is infringed by making<span class="operator">,</span> <span class="keyword">using</span><span class="operator">,</span> selling<span class="operator">,</span> offering <span class="keyword">for</span>
  sale<span class="operator">,</span> <span class="keyword">or</span> importing the Program <span class="keyword">or</span> any portion of it<span class="operator">.</span>

    <span class="number">11.</span> Patents<span class="operator">.</span>

    A <span class="string">&quot;contributor&quot;</span> is a copyright holder who authorizes use under <span class="keyword">this</span>
  License of the Program <span class="keyword">or</span> a work on which the Program is based<span class="operator">.</span>  The
  work thus licensed is called the contributor<span class="char">'s &quot;contributor version&quot;.

    A contributor'</span>s <span class="string">&quot;essential patent claims&quot;</span> are all patent claims
  owned <span class="keyword">or</span> controlled by the contributor<span class="operator">,</span> whether already acquired <span class="keyword">or</span>
  hereafter acquired<span class="operator">,</span> that would be infringed by some manner<span class="operator">,</span> permitted
  by <span class="keyword">this</span> License<span class="operator">,</span> of making<span class="operator">,</span> <span class="keyword">using</span><span class="operator">,</span> <span class="keyword">or</span> selling its contributor version<span class="operator">,</span>
  but <span class="keyword">do</span> <span class="keyword">not</span> <span class="keyword">include</span> claims that would be infringed only as a
  consequence of further modification of the contributor version<span class="operator">.</span>  For
  purposes of <span class="keyword">this</span> definition<span class="operator">,</span> <span class="string">&quot;control&quot;</span> includes the right to grant
  patent sublicenses in a manner consistent with the requirements of
  <span class="keyword">this</span> License<span class="operator">.</span>

    Each contributor grants you a non<span class="operator">-</span>exclusive<span class="operator">,</span> worldwide<span class="operator">,</span> royalty<span class="operator">-</span>free
  patent license under the contributor<span class="char">'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 &quot;patent license&quot; 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 &quot;grant&quot; 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.  &quot;Knowingly relying&quot; means you have
  actual knowledge that, but for the patent license, your conveying the
  covered work in a country, or your recipient'</span>s use of the covered work
  in a country<span class="operator">,</span> would infringe one <span class="keyword">or</span> more identifiable patents in that
  country that you have reason to believe are valid<span class="operator">.</span>

    If<span class="operator">,</span> pursuant to <span class="keyword">or</span> in connection with a single transaction <span class="keyword">or</span>
  arrangement<span class="operator">,</span> you convey<span class="operator">,</span> <span class="keyword">or</span> propagate by procuring conveyance of<span class="operator">,</span> a
  covered work<span class="operator">,</span> and grant a patent license to some of the parties
  receiving the covered work authorizing them to use<span class="operator">,</span> propagate<span class="operator">,</span> modify
  <span class="keyword">or</span> convey a specific copy of the covered work<span class="operator">,</span> then the patent license
  you grant is automatically extended to all recipients of the covered
  work and works based on it<span class="operator">.</span>

    A patent license is <span class="string">&quot;discriminatory&quot;</span> <span class="keyword">if</span> it does <span class="keyword">not</span> <span class="keyword">include</span> within
  the scope of its coverage<span class="operator">,</span> prohibits the exercise of<span class="operator">,</span> <span class="keyword">or</span> is
  conditioned on the non<span class="operator">-</span>exercise of one <span class="keyword">or</span> more of the rights that are
  specifically granted under <span class="keyword">this</span> License<span class="operator">.</span>  You may <span class="keyword">not</span> convey a covered
  work <span class="keyword">if</span> you are a party to an arrangement with a third party that is
  in the business of distributing software<span class="operator">,</span> under which you make payment
  to the third party based on the extent of your activity of conveying
  the work<span class="operator">,</span> and under which the third party grants<span class="operator">,</span> to any of the
  parties who would receive the covered work from you<span class="operator">,</span> a discriminatory
  patent license (a) in connection with copies of the covered work
  conveyed by you (<span class="keyword">or</span> copies made from those copies)<span class="operator">,</span> <span class="keyword">or</span> (b) primarily
  <span class="keyword">for</span> and in connection with specific products <span class="keyword">or</span> compilations that
  contain the covered work<span class="operator">,</span> unless you entered into that arrangement<span class="operator">,</span>
  <span class="keyword">or</span> that patent license was granted<span class="operator">,</span> prior to <span class="number">28</span> March <span class="number">2007.</span>

    Nothing in <span class="keyword">this</span> License shall be construed as excluding <span class="keyword">or</span> limiting
  any implied license <span class="keyword">or</span> other defenses to infringement that may
  otherwise be available to you under applicable patent law<span class="operator">.</span>

    <span class="number">12.</span> No Surrender of Others<span class="char">' 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 &quot;or any later version&quot; 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'</span>s
  <span class="keyword">public</span> statement of acceptance of a version permanently authorizes you
  to choose that version <span class="keyword">for</span> the Program<span class="operator">.</span>

    Later license versions may give you additional <span class="keyword">or</span> different
  permissions<span class="operator">.</span>  However<span class="operator">,</span> no additional obligations are imposed on any
  author <span class="keyword">or</span> copyright holder as a result of your choosing to follow a

              How to Apply These Terms to Your New Programs

    If you develop a <span class="keyword">new</span> program<span class="operator">,</span> and you want it to be of the greatest
  possible use to the <span class="keyword">public</span><span class="operator">,</span> the best way to achieve <span class="keyword">this</span> is to make it
  free software which everyone can redistribute and change under these terms<span class="operator">.</span>

    To <span class="keyword">do</span> so<span class="operator">,</span> attach the following notices to the program<span class="operator">.</span>  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 <span class="string">&quot;copyright&quot;</span> line and a pointer to where the full notice is found<span class="operator">.</span>

      <span class="operator">&lt;</span>one line to give the program<span class="char">'s name and a brief idea of what it does.&gt;
