This License applies to any program or other work which contains anotice placed by the copyright holder saying it may be distributedunder 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 anotherlanguage. (Hereinafter, translation is included without limitation inthe term "modification".) Each licensee is addressed as "you".Activities other than copying, distribution and modification are notcovered by this License; they are outside its scope. The act ofrunning the Program is not restricted, and the output from the Programis covered only if its contents constitute a work based on the Program(independent of having been made by running the Program). Whether thatis true depends on what the Program does.1. You may copy and distribute verbatim copies of the Program's sourcecode as you receive it, in any medium, provided that you conspicuouslyand appropriately publish on each copy an appropriate copyright noticeand disclaimer of warranty; keep intact all the notices that refer tothis License and to the absence of any warranty; and give any otherrecipients of the Program a copy of this License along with theProgram.You may charge a fee for the physical act of transferring a copy, andyou may at your option offer warranty protection in exchange for afee.2. You may modify your copy or copies of the Program or any portion ofit, thus forming a work based on the Program, and copy and distributesuch 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 noticesstating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, thatin whole or in part contains or is derived from the Program or anypart thereof, to be licensed as a whole at no charge to all thirdparties under the terms of this License. c) If the modified program normally reads commands interactivelywhen run, you must cause it, when started running for such interactiveuse in the most ordinary way, to print or display an announcementincluding an appropriate copyright notice and a notice that there isno warranty (or else, saying that you provide a warranty) and thatusers may redistribute the program under these conditions, and tellingthe user how to view a copy of this License. (Exception: if theProgram itself is interactive but does not normally print such anannouncement, your work based on the Program is not required to printan announcement.)These requirements apply to the modified work as a whole. Ifidentifiable sections of that work are not derived from the Program,and can be reasonably considered independent and separate works inthemselves, then this License, and its terms, do not apply to thosesections when you distribute them as separate works. But when youdistribute the same sections as part of a whole which is a work basedon the Program, the distribution of the whole must be on the terms ofthis License, whose permissions for other licensees extend to theentire whole, and thus to each and every part regardless of who wroteit.Thus, it is not the intent of this section to claim rights or contestyour rights to work written entirely by you; rather, the intent is toexercise the right to control the distribution of derivative orcollective works based on the Program.In addition, mere aggregation of another work not based on the Programwith the Program (or with a work based on the Program) on a volume ofa storage or distribution medium does not bring the other work underthe 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 ofSections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readablesource code, which must be distributed under the terms of Sections 1and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least threeyears, to give any third party, for a charge no more than your cost ofphysically performing source distribution, a complete machine-readablecopy of the corresponding source code, to be distributed under theterms of Sections 1 and 2 above on a medium customarily used forsoftware interchange; or, c) Accompany it with the information you received as to theoffer to distribute corresponding source code. (This alternative isallowed only for noncommercial distribution and only if you receivedthe program in object code or executable form with such an offer, inaccord with Subsection b above.)The source code for a work means the preferred form of the work formaking modifications to it. For an executable work, complete sourcecode means all the source code for all modules it contains, plus anyassociated interface definition files, plus the scripts used tocontrol compilation and installation of the executable. However, as aspecial exception, the source code distributed need not includeanything that is normally distributed (in either source or binaryform) with the major components (compiler, kernel, and so on) of theoperating system on which the executable runs, unless that componentitself accompanies the executable.If distribution of executable or object code is made by offeringaccess to copy from a designated place, then offering equivalentaccess to copy the source code from the same place counts asdistribution of the source code, even though third parties are notcompelled to copy the source along with the object code.4. You may not copy, modify, sublicense, or distribute the Programexcept as expressly provided under this License. Any attempt otherwiseto copy, modify, sublicense or distribute the Program is void, andwill automatically terminate your rights under this License. However,parties who have received copies, or rights, from you under thisLicense will not have their licenses terminated so long as suchparties remain in full compliance.5. You are not required to accept this License, since you have notsigned it. However, nothing else grants you permission to modify ordistribute the Program or its derivative works. These actions areprohibited by law if you do not accept this License. Therefore, bymodifying or distributing the Program (or any work based on theProgram), you indicate your acceptance of this License to do so, andall its terms and conditions for copying, distributing or modifyingthe Program or works based on it.6. Each time you redistribute the Program (or any work based on theProgram), the recipient automatically receives a license from theoriginal licensor to copy, distribute or modify the Program subject tothese terms and conditions. You may not impose any furtherrestrictions on the recipients' exercise of the rights grantedherein. You are not responsible for enforcing compliance by thirdparties to this License.7. If, as a consequence of a court judgment or allegation of patentinfringement or for any other reason (not limited to patent issues),conditions are imposed on you (whether by court order, agreement orotherwise) that contradict the conditions of this License, they do notexcuse you from the conditions of this License. If you cannotdistribute so as to satisfy simultaneously your obligations under thisLicense and any other pertinent obligations, then as a consequence youmay not distribute the Program at all. For example, if a patentlicense would not permit royalty-free redistribution of the Program byall those who receive copies directly or indirectly through you, thenthe only way you could satisfy both it and this License would be torefrain entirely from distribution of the Program.If any portion of this section is held invalid or unenforceable underany particular circumstance, the balance of the section is intended toapply and the section as a whole is intended to apply in othercircumstances.It is not the purpose of this section to induce you to infringe anypatents or other property right claims or to contest validity of anysuch claims; this section has the sole purpose of protecting theintegrity of the free software distribution system, which isimplemented by public license practices. Many people have madegenerous contributions to the wide range of software distributedthrough that system in reliance on consistent application of thatsystem; it is up to the author/donor to decide if he or she is willingto distribute software through any other system and a licensee cannotimpose that choice.This section is intended to make thoroughly clear what is believed tobe a consequence of the rest of this License.8. If the distribution and/or use of the Program is restricted incertain countries either by patents or by copyrighted interfaces, theoriginal copyright holder who places the Program under this Licensemay add an explicit geographical distribution limitation excludingthose countries, so that distribution is permitted only in or amongcountries not thus excluded. In such case, this License incorporatesthe limitation as if written in the body of this License.9. The Free Software Foundation may publish revised and/or newversions of the General Public License from time to time. Such newversions will be similar in spirit to the present version, but maydiffer in detail to address new problems or concerns.Each version is given a distinguishing version number. If the Programspecifies a version number of this License which applies to it and"any later version", you have the option of following the terms andconditions either of that version or of any later version published bythe Free Software Foundation. If the Program does not specify aversion number of this License, you may choose any version everpublished by the Free Software Foundation.10. If you wish to incorporate parts of the Program into other freeprograms whose distribution conditions are different, write to theauthor to ask for permission. For software which is copyrighted by theFree Software Foundation, write to the Free Software Foundation; wesometimes make exceptions for this. Our decision will be guided by thetwo goals of preserving the free status of all derivatives of our freesoftware and of promoting the sharing and reuse of software generally.NO WARRANTY11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NOWARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OROTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANYKIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THEIMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULARPURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THEPROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUMETHE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO INWRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFYAND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOUFOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL ORCONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THEPROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEINGRENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR AFAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IFSUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCHDAMAGES.
