                        GNU GENERAL PUBLIC LICENSE
                          Version 3, 29 June 2007

Copyright © 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 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
<http://www.gnu.org/licenses/>.

    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
<http://www.gnu.org/philosophy/why-not-lgpl.html>.
