 Copyright (C) 1989, 1991 Free Software Foundation, Inc.

 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.

 Preamble

 The licenses for most software are designed to take away your
freedom to share and change it.  By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users.  This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it.  (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.)  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 the
software.

 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 FOR COPYING,
                         DISTRIBUTION AND MODIFICATION

  0. This License applies to any program or other work which contains
  a notice placed by the copyright holder saying it may be distributed
  under the terms of this General Public License.  The "Program", below,
  refers to any such program or work, and a "work based on the Program"
  means either the Program or any derivative work under copyright law:
  that is to say, a work containing the Program or a portion of it,
  either verbatim or with modifications and/or translated into another
  language.  (Hereinafter, translation is included without limitation in
  the term "modification".)  Each licensee is addressed as "you".

  Activities other than copying, distribution and modification are not
  covered by this License; they are outside its scope.  The act of
  running the Program is not restricted, and the output from the Program
  is covered only if its contents constitute a work based on the
  Program (independent of having been made by running the Program).
  Whether that is true depends on what the Program does.

  1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the
  notices that refer to this License and to the absence of any warranty;
  and give any other recipients of the Program a copy of this License
  along with the Program.

  You may charge a fee for the physical act of transferring a copy, and
  you may at your option offer warranty protection in exchange for a
  fee.

  2. You may modify your copy or copies of the Program or any portion
  of it, thus forming a work based on the Program, and copy and
  distribute such modifications or work under the terms of Section 1
  above, provided that you also meet all of these conditions:

    a) You must cause the modified files to carry prominent notices
    stating that you changed the files and the date of any change.

    b) You must cause any work that you distribute or publish, that in
    whole or in part contains or is derived from the Program or any
    part thereof, to be licensed as a whole at no charge to all third
    parties under the terms of this License.

    c) If the modified program normally reads commands interactively
    when run, you must cause it, when started running for such
    interactive use in the most ordinary way, to print or display an
    announcement including an appropriate copyright notice and a
    notice that there is no warranty (or else, saying that you provide
    a warranty) and that users may redistribute the program under
    these conditions, and telling the user how to view a copy of this
    License.  (Exception: if the Program itself is interactive but
    does not normally print such an announcement, your work based on
    the Program is not required to print an announcement.)

  These requirements apply to the modified work as a whole.  If
  identifiable sections of that work are not derived from the Program,
  and can be reasonably considered independent and separate works in
  themselves, then this License, and its terms, do not apply to those
  sections when you distribute them as separate works.  But when you
  distribute the same sections as part of a whole which is a work based
  on the Program, the distribution of the whole must be on the terms of
  this License, whose permissions for other licensees extend to the
  entire whole, and thus to each and every part regardless of who wrote
  it.

  Thus, it is not the intent of this section to claim rights or contest
  your rights to work written entirely by you; rather, the intent is to
  exercise the right to control the distribution of derivative or
  collective works based on the Program.

  3. You may copy and distribute the Program (or a work based on it,
  under Section 2) in object code or executable form under the terms of
  Sections 1 and 2 above provided that you also do one of the following:

    a) Accompany it with the complete corresponding machine-readable
    source code, which must be distributed under the terms of Sections
    1 and 2 above on a medium customarily used for software interchange; or,

    b) Accompany it with a written offer, valid for at least three
    years, to give any third party, for a charge no more than your
    cost of physically performing source distribution, a complete
    machine-readable copy of the corresponding source code, to be
    distributed under the terms of Sections 1 and 2 above; or,

    c) Accompany it with the information you received as to the offer
    to distribute corresponding source code.  (This alternative is
    allowed only for noncommercial distribution and only if you
    received the program in object code or executable form with such
    an offer, in accord with Subsection b above.)

  The source code for a work means the preferred form of the work for
  making modifications to it.  For an executable work, complete source
  code means all the source code for all modules it contains, plus any
  associated interface definition files, plus the scripts used to
  control compilation and installation of the executable.  However, as
  a special exception, the source code distributed need not include
  anything that is normally distributed (in either source or binary
  form) with the major components (compiler, kernel, and so on) of the
  operating system on which the executable runs, unless that component
  itself accompanies the executable.

  4. You may not copy, modify, sublicense, or distribute the Program
  except as expressly provided under this License.  Any attempt
  otherwise to copy, modify, sublicense or distribute the Program is
  void, and will automatically terminate your rights under this
  License.  However, parties who have received copies, or rights, from
  you under this License will not have their licenses terminated so
  long as such parties remain in full compliance.

  5. You are not required to accept this License, since you have not
  signed it.  However, nothing else grants you permission to modify or
  distribute the Program or its derivative works.  These actions are
  prohibited by law if you do not accept this License.  Therefore, by
  modifying or distributing the Program (or any work based on the
  Program), you indicate your acceptance of this License to do so.

  6. Each time you redistribute the Program (or any work based on the
  Program), the recipient automatically receives a license from the
  original licensor to copy, distribute or modify the Program subject to
  these terms and conditions.  You may not impose any further
  restrictions on the recipients' exercise of the rights granted herein.
  You are not responsible for enforcing compliance by third parties to
  this License.

  7. If, as a consequence of a court judgment or allegation of patent
  infringement or for any other reason (not limited to patent issues),
  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
  distribute so as to satisfy simultaneously your obligations under this
  License and any other pertinent obligations, then as a consequence you
  may not distribute the Program at all.  For example, if a patent
  license would not permit royalty-free redistribution of the Program by
  all those who receive copies directly or indirectly through you, then
  the only way you could distribute the Program would be to refrain
  entirely from distribution.

  If any portion of this section is held invalid or unenforceable under
  any particular circumstance, the balance of the section is intended to
  apply and the section as a whole is intended to apply in other
  circumstances.

  8. If the distribution and/or use of the Program is restricted in
  certain countries either by patents or by copyrighted interfaces, the
  original copyright holder who places the Program under this License
  may add an explicit geographical distribution limitation excluding
  those countries, so that distribution is permitted only in or among
  countries not thus excluded.  In such case, this License incorporates
  the limitation as if written in the body of this License.

  9. The Free Software Foundation may publish revised and/or new
  versions of the 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 a version number of this License which applies to
  it and "any later version", you have the option of following the
  terms and conditions either of that version or of any later version
  published by the Free Software Foundation.  If the Program does not
  specify a version number of this License, you may choose any version
  ever published by the Free Software Foundation.

  10. If you wish to incorporate parts of the Program into other free
  programs whose distribution conditions are different, write to the
  author to ask for permission.  For software which is copyrighted by
  the Free Software Foundation, permission is given in the form of a
  separate Agreement.  However, for software which is copyrighted by
  other parties, the General Public License gives no permission to
  distribute the Program in such a fashion, and those parties who
  might wish to copy and distribute the Program in such a fashion must
  contact the appropriate copyright holders for permission.

  11. If the distribution and/or use of the Program is restricted in
  certain countries either by patents or by copyrighted interfaces, the
  original copyright holder who places the Program under this License
  may add an explicit geographical distribution limitation excluding
  those countries, so that distribution is permitted only in or among
  countries not thus excluded.  In such case, this License incorporates
  the limitation as if written in the body of this License.

  12. The Free Software Foundation may publish revised and/or new
  versions of the 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.

  13. Any attempt to copy, modify, sublicense or distribute the
  Program except as provided under this License is void and will
  automatically terminate your rights under this License.

  14. If the distribution and/or use of the Program is restricted in
  certain countries either by patents or by copyrighted interfaces, the
  original copyright holder who places the Program under this License
  may add an explicit geographical distribution limitation excluding
  those countries, so that distribution is permitted only in or among
  countries not thus excluded.  In such case, this License incorporates
  the limitation as if written in the body of this License.

  15. The Free Software Foundation may publish revised and/or new
  versions of the 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.

  16. Any attempt to copy, modify, sublicense or distribute the
  Program except as provided under this License is void and will
  automatically terminate your rights under this License.

  17. If you have any questions about this License, or about the
  applicability of this License to a particular program or situation,
  contact the Free Software Foundation, 51 Franklin Street, Fifth
  Floor, Boston, MA 02110-1301 USA.
