 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 Library 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
 this service 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 make restrictions that forbid
 anyone to deny you these rights or to ask you to surrender the rights.
 These restrictions translate to certain responsibilities for you if you
 distribute copies of the software, or if you modify it.
 
   For example, if you distribute copies of such a program, whether
 gratis or for a fee, you must give the recipients all the rights that
 you have.  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.
 
   We protect your rights with two steps: (1) copyright the software, and
 (2) offer you this license which gives you legal permission to copy,
 distribute and/or modify the software.
 
   Also, for each author's protection and ours, we want to make certain
 that everyone understands that there is no warranty for this free
 software.  If the software is modified by someone else and passed on, we
 want its recipients to know that what they have is not the original, so
 that any problems introduced by others will not reflect on the original
 authors' reputations.
 
   Finally, any free program is threatened constantly by software
 patents.  We wish to avoid the danger that redistributors of a free
 program will individually obtain patent licenses, in effect making the
 program proprietary.  To prevent this, we have made it clear that any
 patent must be licensed for everyone's free use or not licensed at all.
 
   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.
 
 In addition, mere aggregation of another work not based on the Program
 with the Program (or with a work based on the Program) on a volume of
 a storage or distribution medium does not bring the other work under
 the scope of this License.
 
 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 on a medium customarily used for
    software interchange; 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.
 
 If distribution of executable or object code is made by offering
 access to copy from a designated place, then offering equivalent
 access to copy the source code from the same place counts as
 distribution of the source code, even though third parties are not
 compelled to copy the source along with the object code.
 
 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, and
 all its terms and conditions for copying, distributing or modifying
 the Program or works based on it.
 
 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 satisfy both it and this License would be to
 refrain entirely from distribution of the Program.
 
 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.
 
 It is not the purpose of this section to induce you to infringe any
 patents or other property right claims or to contest validity of any
 such claims; this section has the sole purpose of protecting the
 integrity of the free software distribution system, which is
 implemented by public license practices.  Many people have made
 generous contributions to the wide range of software distributed
 through that system in reliance on consistent application of that
 system; it is up to the author/donor to decide if he or she is willing
 to distribute software through any other system and a licensee cannot
 impose that choice.
 
 This section is intended to make thoroughly clear what is believed to
 be a consequence of the rest of this License.
 
 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, write to the Free Software Foundation;
 we sometimes make exceptions for this.  Our decision will be guided by
 the two goals of preserving the free status of all derivatives of our
 free software and of promoting the sharing and reuse of software
 generally.
 
 NO WARRANTY
 
 11.
  
 BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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.
 
 12.
 
 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
 REDISTRIBUTE 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.
 
 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
 convey 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 an idea of what it does.
 Copyright (C) 20<yy>  <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 2 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, write to the Free Software
 Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307,
 USA. 
 
 Also add information on how to contact you by electronic and paper mail.
 
 If the program is interactive, make it output a short notice like this
 when it starts in an interactive mode:
 
  Gnomovision version 69, Copyright (C) 20<yy> <name of author> 
  Gnomovision 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, the
 commands you use may be called something other than `show w' and `show
 c'; they could even be mouse-clicks or menu items--whatever suits your
 program.
 
 You should also get your employer (if you work as a programmer) or
 your school, if any, to sign a "copyright disclaimer" for the program,
 if necessary.  Here is a sample; alter the names:
 
  Yoyodyne, Inc., hereby disclaims all copyright
  interest in the program `Gnomovision'
  (which makes passes at compilers) written 
  by James Hacker.
 
  <signature of Ty Coon>, 1 April 1989
  Ty Coon, President of Vice
 
 This 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 Library General Public License instead of this License.
