GPL(GNU)                   Free Software Foundation                   GPL(GNU)



                             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 pro-
       grams, 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  modi-
       fied  versions  of  the software inside them, although the manufacturer
       can do so.  This is fundamentally incompatible with the aim of protect-
       ing  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  ver-
       sions 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  modifi-
       cation 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 "recip-
       ients" 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  per-
       mission, 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 convey-
       ing.

       An interactive user interface displays "Appropriate Legal  Notices"  to
       the  extent  that it includes a convenient and prominently visible fea-
       ture 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  promi-
       nent 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 Compo-
       nent,  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 con-
       trol those activities.  However, it does not include the work's  System
       Libraries,  or  general-purpose  tools or generally available free pro-
       grams 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 copy-
       right on the Program, and are irrevocable provided  the  stated  condi-
       tions  are met.  This License explicitly affirms your unlimited permis-
       sion 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 facil-
       ities  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 mea-
       sure  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  circumven-
       tion  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  appro-
       priately  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 permis-
           sion 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 Cor-
           responding 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  writ-
           ten  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 customar-
           ily 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  alterna-
           tive  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 Corre-
           sponding  Source  in the same way through the same place at no fur-
           ther charge.  You need not require recipients to  copy  the  Corre-
           sponding  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 Corre-
           sponding 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 incorpora-
       tion 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 partic-
       ular 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, proce-
       dures, 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 modifi-
       cation 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 recipi-
       ent, 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 docu-
       mented (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.  Addi-
       tional 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 per-
       missions  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 rea-
           sonable 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  restric-
       tion,  you may remove that term.  If a license document contains a fur-
       ther 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 pro-
       vided 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 para-
       graph 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 occur-
       ring 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 avail-
       able, or (2) arrange to deprive yourself of the benefit of  the  patent
       license  for  this particular work, or (3) arrange, in a manner consis-
       tent 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 arrange-
       ment, 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 busi-
       ness 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 permis-
       sion to link or combine any covered work with  a  work  licensed  under
       version  3  of the GNU Affero General Public License into a single com-
       bined 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 permis-
       sions.  However, no additional obligations are imposed on any author or
       copyright  holder  as  a result of your choosing to follow a later ver-
       sion.

       15. Disclaimer of Warranty.

       THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLI-
       CABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLD-
       ERS 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 PARTIC-
       ULAR 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  CON-
       VEYS  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 OPER-
       ATE 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  Pro-
       gram,  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 mod-

       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  redis-
           tribute it under certain conditions; type "show c" for details.

       The  hypothetical commands "show w" and "show c" should show the appro-
       priate 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 pro-
       gram 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>.
