+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
