GNU GENERAL PUBLIC LICENSE		     Version 1, February 1989 Copyright (C) 1989 Free Software Foundation, Inc.                    675 Mass Ave, Cambridge, MA 02139, USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.			    Preamble  The license agreements of most software companies try to keep usersat the mercy of those companies.  By contrast, our General PublicLicense is intended to guarantee your freedom to share and change freesoftware--to make sure the software is free for all its users.  TheGeneral Public License applies to the Free Software Foundation'ssoftware and to any other program whose authors commit to using it.You can use it for your programs, too.  When we speak of free software, we are referring to freedom, notprice.  Specifically, the General Public License is designed to makesure that you have the freedom to give away or sell copies of freesoftware, 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 freeprograms; and that you know you can do these things.  To protect your rights, we need to make restrictions that forbidanyone to deny you these rights or to ask you to surrender the rights.These restrictions translate to certain responsibilities for you if youdistribute copies of the software, or if you modify it.  For example, if you distribute copies of a such a program, whethergratis or for a fee, you must give the recipients all the rights thatyou have.  You must make sure that they, too, receive or can get thesource code.  And you must tell them 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 certainthat everyone understands that there is no warranty for this freesoftware.  If the software is modified by someone else and passed on, wewant its recipients to know that what they have is not the original, sothat any problems introduced by others will not reflect on the originalauthors' reputations.  The precise terms and conditions for copying, distribution andmodification follow.		    GNU GENERAL PUBLIC LICENSE   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION  0. This License Agreement applies to any program or other work whichcontains a notice placed by the copyright holder saying it may bedistributed under the terms of this General Public License.  The"Program", below, refers to any such program or work, and a "work basedon the Program" means either the Program or any work containing theProgram or a portion of it, either verbatim or with modifications.  Eachlicensee is addressed as "you".  1. You may copy and distribute verbatim copies of the Program's sourcecode as you receive it, in any medium, provided that you conspicuously andappropriately publish on each copy an appropriate copyright notice anddisclaimer of warranty; keep intact all the notices that refer to thisGeneral Public License and to the absence of any warranty; and give anyother recipients of the Program a copy of this General Public Licensealong with the Program.  You may charge a fee for the physical act oftransferring a copy.  2. You may modify your copy or copies of the Program or any portion ofit, and copy and distribute such modifications under the terms of Paragraph1 above, provided that you also do the following:    a) cause the modified files to carry prominent notices stating that    you changed the files and the date of any change; and    b) cause the whole of any work that you distribute or publish, that    in whole or in part contains the Program or any part thereof, either    with or without modifications, to be licensed at no charge to all    third parties under the terms of this General Public License (except    that you may choose to grant warranty protection to some or all    third parties, at your option).    c) If the modified program normally reads commands interactively when    run, you must cause it, when started running for such interactive use    in the simplest and most usual 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 General    Public License.    d) 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.Mere aggregation of another independent work with the Program (or itsderivative) on a volume of a storage or distribution medium does not bringthe other work under the scope of these terms.  3. You may copy and distribute the Program (or a portion or derivative ofit, under Paragraph 2) in object code or executable form under the terms ofParagraphs 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    Paragraphs 1 and 2 above; or,    b) accompany it with a written offer, valid for at least three    years, to give any third party free (except for a nominal charge    for the cost of distribution) a complete machine-readable copy of the    corresponding source code, to be distributed under the terms of    Paragraphs 1 and 2 above; or,    c) accompany it with the information you received as to where the    corresponding source code may be obtained.  (This alternative is    allowed only for noncommercial distribution and only if you    received the program in object code or executable form alone.)Source code for a work means the preferred form of the work for makingmodifications to it.  For an executable file, complete source code meansall the source code for all modules it contains; but, as a specialexception, it need not include source code for modules which are standardlibraries that accompany the operating system on which the executablefile runs, or for standard header files or definitions files thataccompany that operating system.  4. You may not copy, modify, sublicense, distribute or transfer theProgram except as expressly provided under this General Public License.Any attempt otherwise to copy, modify, sublicense, distribute or transferthe Program is void, and will automatically terminate your rights to usethe Program under this License.  However, parties who have receivedcopies, or rights to use copies, from you under this General PublicLicense will not have their licenses terminated so long as such partiesremain in full compliance.  5. By copying, distributing or modifying the Program (or any work basedon the Program) you indicate your acceptance of this license to do so,and all its terms and conditions.  6. Each time you redistribute the Program (or any work based on theProgram), the recipient automatically receives a license from the originallicensor to copy, distribute or modify the Program subject to theseterms and conditions.  You may not impose any further restrictions on therecipients' exercise of the rights granted herein.  7. The Free Software Foundation may publish revised and/or new versionsof the General Public License from time to time.  Such new versions willbe similar in spirit to the present version, but may differ in detail toaddress new problems or concerns.Each version is given a distinguishing version number.  If the Programspecifies a version number of the license which applies to it and "anylater version", you have the option of following the terms and conditionseither of that version or of any later version published by the FreeSoftware Foundation.  If the Program does not specify a version number ofthe license, you may choose any version ever published by the Free SoftwareFoundation.  8. If you wish to incorporate parts of the Program into other freeprograms whose distribution conditions are different, write to the authorto ask for permission.  For software which is copyrighted by the FreeSoftware Foundation, write to the Free Software Foundation; we sometimesmake exceptions for this.  Our decision will be guided by the two goalsof preserving the free status of all derivatives of our free software andof promoting the sharing and reuse of software generally.			    NO WARRANTY  9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTYFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHENOTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIESPROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSEDOR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OFMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK ASTO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THEPROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,REPAIR OR CORRECTION.  10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITINGWILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/ORREDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISINGOUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITEDTO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BYYOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHERPROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THEPOSSIBILITY OF SUCH DAMAGES.		     END OF TERMS AND CONDITIONS	Appendix: How to Apply These Terms to Your New Programs  If you develop a new program, and you want it to be of the greatestpossible use to humanity, the best way to achieve this is to make itfree software which everyone can redistribute and change under theseterms.  To do so, attach the following notices to the program.  It is safest toattach them to the start of each source file to most effectively conveythe 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) 19yy  <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 1, 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., 675 Mass Ave, Cambridge, MA 02139, 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 thiswhen it starts in an interactive mode:    Gnomovision version 69, Copyright (C) 19xx 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 theappropriate parts of the General Public License.  Of course, thecommands you use may be called something other than `show w' and `showc'; they could even be mouse-clicks or menu items--whatever suits yourprogram.You should also get your employer (if you work as a programmer) or yourschool, if any, to sign a "copyright disclaimer" for the program, ifnecessary.  Here a sample; alter the names:  Yoyodyne, Inc., hereby disclaims all copyright interest in the  program `Gnomovision' (a program to direct compilers to make passes  at assemblers) written by James Hacker.  <signature of Ty Coon>, 1 April 1989  Ty Coon, President of ViceThat's all there is to it!
