dda29597012dd9033f6bbf3334ab4d7af77a459btweenk Preamble

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk The licenses for most software are designed to take away your

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkfreedom to share and change it. By contrast, the GNU General Public

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkLicense is intended to guarantee your freedom to share and change free

dda29597012dd9033f6bbf3334ab4d7af77a459btweenksoftware--to make sure the software is free for all its users. This

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkGeneral Public License applies to most of the Free Software

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkFoundation's software and to any other program whose authors commit to

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkusing it. (Some other Free Software Foundation software is covered by

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkthe GNU Lesser General Public License instead.) You can apply it to

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkyour programs, too.

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk When we speak of free software, we are referring to freedom, not

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkprice. Our General Public Licenses are designed to make sure that you

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkhave the freedom to distribute copies of free software (and charge for

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkthis service if you wish), that you receive source code or can get it

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkif you want it, that you can change the software or use pieces of it

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkin new free programs; and that you know you can do these things.

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk To protect your rights, we need to make restrictions that forbid

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkanyone to deny you these rights or to ask you to surrender the rights.

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkThese restrictions translate to certain responsibilities for you if you

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkdistribute copies of the software, or if you modify it.

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk For example, if you distribute copies of such a program, whether

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkgratis or for a fee, you must give the recipients all the rights that

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkyou have. You must make sure that they, too, receive or can get the

dda29597012dd9033f6bbf3334ab4d7af77a459btweenksource code. And you must show them these terms so they know their

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkrights.

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk We protect your rights with two steps: (1) copyright the software, and

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk(2) offer you this license which gives you legal permission to copy,

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkdistribute and/or modify the software.

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk Also, for each author's protection and ours, we want to make certain

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkthat everyone understands that there is no warranty for this free

dda29597012dd9033f6bbf3334ab4d7af77a459btweenksoftware. If the software is modified by someone else and passed on, we

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkwant its recipients to know that what they have is not the original, so

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkthat any problems introduced by others will not reflect on the original

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkauthors' reputations.

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk Finally, any free program is threatened constantly by software

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkpatents. We wish to avoid the danger that redistributors of a free

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkprogram will individually obtain patent licenses, in effect making the

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkprogram proprietary. To prevent this, we have made it clear that any

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkpatent must be licensed for everyone's free use or not licensed at all.

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk The precise terms and conditions for copying, distribution and

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkmodification follow.

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk 0. This License applies to any program or other work which contains

dda29597012dd9033f6bbf3334ab4d7af77a459btweenka notice placed by the copyright holder saying it may be distributed

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkunder the terms of this General Public License. The "Program", below,

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkrefers to any such program or work, and a "work based on the Program"

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkmeans either the Program or any derivative work under copyright law:

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkthat is to say, a work containing the Program or a portion of it,

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkeither verbatim or with modifications and/or translated into another

dda29597012dd9033f6bbf3334ab4d7af77a459btweenklanguage. (Hereinafter, translation is included without limitation in

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkthe term "modification".) Each licensee is addressed as "you".

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkActivities other than copying, distribution and modification are not

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkcovered by this License; they are outside its scope. The act of

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkrunning the Program is not restricted, and the output from the Program

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkis covered only if its contents constitute a work based on the

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkProgram (independent of having been made by running the Program).

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkWhether that is true depends on what the Program does.

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk 1. You may copy and distribute verbatim copies of the Program's

dda29597012dd9033f6bbf3334ab4d7af77a459btweenksource code as you receive it, in any medium, provided that you

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkconspicuously and appropriately publish on each copy an appropriate

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkcopyright notice and disclaimer of warranty; keep intact all the

dda29597012dd9033f6bbf3334ab4d7af77a459btweenknotices that refer to this License and to the absence of any warranty;

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkand give any other recipients of the Program a copy of this License

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkalong with the Program.

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkYou may charge a fee for the physical act of transferring a copy, and

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkyou may at your option offer warranty protection in exchange for a fee.

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk 2. You may modify your copy or copies of the Program or any portion

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkof it, thus forming a work based on the Program, and copy and

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkdistribute such modifications or work under the terms of Section 1

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkabove, provided that you also meet all of these conditions:

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk a) You must cause the modified files to carry prominent notices

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk stating that you changed the files and the date of any change.

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk b) You must cause any work that you distribute or publish, that in

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk whole or in part contains or is derived from the Program or any

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk part thereof, to be licensed as a whole at no charge to all third

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk parties under the terms of this License.

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk c) If the modified program normally reads commands interactively

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk when run, you must cause it, when started running for such

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk interactive use in the most ordinary way, to print or display an

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk announcement including an appropriate copyright notice and a

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk notice that there is no warranty (or else, saying that you provide

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk a warranty) and that users may redistribute the program under

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk these conditions, and telling the user how to view a copy of this

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk License. (Exception: if the Program itself is interactive but

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk does not normally print such an announcement, your work based on

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk the Program is not required to print an announcement.)

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkThese requirements apply to the modified work as a whole. If

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkidentifiable sections of that work are not derived from the Program,

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkand can be reasonably considered independent and separate works in

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkthemselves, then this License, and its terms, do not apply to those

dda29597012dd9033f6bbf3334ab4d7af77a459btweenksections when you distribute them as separate works. But when you

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkdistribute the same sections as part of a whole which is a work based

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkon the Program, the distribution of the whole must be on the terms of

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkthis License, whose permissions for other licensees extend to the

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkentire whole, and thus to each and every part regardless of who wrote it.

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkThus, it is not the intent of this section to claim rights or contest

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkyour rights to work written entirely by you; rather, the intent is to

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkexercise the right to control the distribution of derivative or

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkcollective works based on the Program.

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkIn addition, mere aggregation of another work not based on the Program

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkwith the Program (or with a work based on the Program) on a volume of

dda29597012dd9033f6bbf3334ab4d7af77a459btweenka storage or distribution medium does not bring the other work under

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkthe scope of this License.

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk

dda29597012dd9033f6bbf3334ab4d7af77a459btweenk 3. You may copy and distribute the Program (or a work based on it,

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkunder Section 2) in object code or executable form under the terms of

dda29597012dd9033f6bbf3334ab4d7af77a459btweenkSections 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

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) <year> <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 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:

Gnomovision version 69, Copyright (C) year 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 Lesser General

Public License instead of this License.
