- This program is distributed in the hope that it will be useful,

- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
- GNU General Public License below for more details.
- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
- 675 Mass Ave, Cambridge, MA 02139, USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
- Preamble
- The 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
