You may charge a fee for the ph ysical act o f trans ferring a cop y, and you ma y at your option offer warranty protection in exchange for a fee.2. You may modi fy your copy or copies o f the Program or any portion o f it, thus forming awork based on the Program, and copy and distribute such modi fications or work unde r the terms o f Section 1 above, provided that you also meet all o f these conditions: a) You must cause the modified files to carry prominent notices stating that you changedthe files and the date o f any change.b) You must cause any wor k that you distri bute or pu blish, that in w hole or in par t contains or is derived from the Program or any part thereo f, to be licensed as a whole at no charge to all third parties under the terms of this License .c) I f the modi fied program normally reads commands interactively when run, you mus t cause it, when started running for such interactive use in the most ordinary way, to print or disp lay an announcement inc luding an appropriate copyrig ht notice an d a notice that t here is no warranty (or e lse, saying t hat you provi de a warranty) an d that users may redistri bute t he program un der these con ditions, an d te lling t he user how to view a copy o f this License. (Exception: i f the Program itsel f is interactive but does not normally print suc h an announcement, your wor k based on t he Program is not required to print an announcement.)These requirements apply to the modified work as a whole. I f identi fiable sections o f that work are not derived from the Program, and can be reasonably considered independent and separate wor ks in t hemse lves, t hen this License, an d its terms, do not app ly to t hose sections w hen you distri bute t hem as separate wor ks. But w hen you distri bute t he same sections as part o f a whole which is a work based on the Program, the distribution o f the whole must be on the terms of this License, whose permissions for other licensees extendto 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 co llective wor ks base d on t he Program.In addition, mere aggregation o f 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 an d distri bute t he Program (or a wor k based on it, un der Section 2) in object code or executable form under the terms o f Sections 1 and 2 above provided tha t you also do one of the following:a) Accompany it with the comp lete correspon ding mac hine-rea dable source co de, which m ust be distri buted under the te rm s of Sect i o n s 1 and 2 abo ve on a m ed ium customarily used for so ftware 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 o f physically per forming source distribution, acomplete machine-readable copy of the corresponding source code, to be distributedunder the terms of Sections 1 and 2 above on a medium customaril y used for so ftwareinterchange; or ,c) Accompan y it with the in formation you received as to the o ffer 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 pre ferred form o f 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 inter face de finition files, plus the scripts used to control compilation and installation of the executable. However, as aspecial exception, t he source co de distri bute d nee d not inc lude an ything t hat is norma lly distributed (in either source or binary form) with the major components (compiler, kernel, and so on) o f the operating system on which the executable runs, unless that component itself accompanies the executable . I f distribution o f executable or object code is made b y offering access to cop y from a designated place, then o ffering 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 t he source a long wit h the o bject co de.4. You ma y not cop y, modi fy, sublicense, or distribute the Program except as expressl y provided under this License. Any attempt otherwise to copy, modify, sublicense or distri bute t he Program is voi d, and wi ll automatica lly terminate your rig hts un der t his 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 require d to accept t his License, since you have not signe d it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law i f you do not accept this License. There fore, b y 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 re distri bute t he Program (or any wor k based on t he Program), t he 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 an y further restrictions on the recipients' exercise o f the rights granted herein. You are not responsible for en forcing compliance by third parties to this License .7. I f, as a consequence o f a court judgment or allegation o f patent in fringement or for an y other reason (not limite d to patent issues), con ditions are impose d on you (w hether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions o f this License. I f you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinen t obligations, t hen as a consequence you ma y not distri bute t he Program at a ll. For example, if a patent license would not permit ro yalty-free redistribution o f the Program by all those w ho receive copies direct ly or in direct ly throug h you, t hen t he on ly wa y you could satisfy both it and this License would be to re frain entirel y from distribution o f the Program. If any portion o f this section is held invalid or unen forceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to app ly in ot her circumstances. It is not the purpose of this section to induce you to in fringe 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 o f the free so ftware distribution system, which is imp lemente d by pu blic license practices. Many peop le have ma de generouscontributions 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 i f he or she is willing to distribute software through any other system and a licensee cannot impose that c hoice. Th is section is inten ded to ma ke thoroug hly c lear w hat is believe d to be a consequence of the rest o f this License.8. If the distribution and/or use o f the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program un der t his License may a dd an exp licit geograp hical distri bution limitation excluding t hose countries, so t hat distri bution is permitte d 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 So ftware Foundation may publish revised and/or new versions o f 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 speci fies 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 o f that version or o f any later version published by the Free Software Foundation. I f the Program does not speci fy a version number of this License, you may choose any version ever published by the Free So ftware Foundation.10. If you wish to incorporate parts o f the Program into other free programs whose distribution conditions are diff erent, write to the author to ask for permission. Fo r software which is copyrighted by the Free So ftware Foundation, write to the FreeSoftware Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status o f all derivatives o f our free software and o f promoting the sharing and reuse o f so ftware generally.NO WARRANTY11.

It is sa fest to attach them to the start o f each source file to most e ffectively convey the exclusion o f 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 o f what it does.>Copyright (C) <year> <name of author >This program is free so ftware; you can redistribute it and/or modi fy it under the termsof the GNU General Public License as published by the Free So ftware Foundation; eithe r version 2 of the License, or (at your option) any later version .This program is distributed in the hope that it will be use ful, but WITHOUT AN Y WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
