                         GNU GENERAL PUBLIC LICENSE

                            Version 2, June 1991

      Copyright (C) 1989, 1991 Free Software Foundation, Inc.

        51 Franklin Street, Fifth Floor, Boston, MA 02110, USA

      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.

                         GNU GENERAL PUBLIC LICENSE

        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

             Appendix: 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 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 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., 51 Franklin St, 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:

         Gnomovision version 69, Copyright (C) 19yy 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.
