-
-GNU General Public License
-
-Version 2, June 1991
-
-Copyright (C) 1989, 1991 Free Software Foundation, Inc.
-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.
-
-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 an idea of what it does.
-Copyright (C) yyyy 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) 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 Library General Public
-License instead of this License.

- * The 82580 timesync updates the system timer every 8ns by 8ns,

- *
- * Neither the 82576 nor the 82580 offer registers wide enough to hold
- * nanoseconds time values for very long. For the 82580, SYSTIM always
- * counts nanoseconds, but the upper 24 bits are not available. The
- * frequency is adjusted by changing the 32 bit fractional nanoseconds
- * register, TIMINCA.
- *
- * For the 82576, the SYSTIM register time unit is affect by the
- * choice of the 24 bit TININCA:IV (incvalue) field. Five bits of this
- * field are needed to provide the nominal 16 nanosecond period,
- * leaving 19 bits for fractional nanoseconds.
- *
- * We scale the NIC clock cycle by a large factor so that relatively
- * small clock corrections can be added or subtracted at each clock
- * tick. The drawbacks of a large factor are a) that the clock
- * register overflows more quickly (not such a big deal) and b) that
- * the increment per tick has to fit into 24 bits. As a result we
- * need to use a shift of 19 so we can fit a value of 16 into the

-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.
-
-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 an idea of what it does.
-Copyright (C) yyyy 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) 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 Library General Public
-License instead of this License.
