:                        59 Temple Place, Suite 330, Boston, MA  02111-1307  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

: 

: 	    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., 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) 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.

:   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.
