			             *** PREAMBLE ***

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

    When we speak of free software, we are referring to freedom, not
  price. Our General Public Licenses are designed to make sure that you
  have the freedom to distribute copies of free software (and charge for
  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.

=========================== TERMS AND CONDITIONS ===========================

The precise terms and conditions for copying, distribution and modification follow.

  (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.

  (11)----------------------------------------------------------------------

   NO WARRANTY

   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.

  //----------------------------------------------------------------------\\

  | (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.,|
  | 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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:

  //----------------------------------------------------------------------\\
  |                                                                        |

  | 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:

  //----------------------------------------------------------------------\\

  \\----------------------------------------------------------------------//

  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 Lesser General
  Public License instead of this License.
