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". </para><para>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. </para><para><emphasis role="strong">1.</emphasis>  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. </para><para>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. </para><para><emphasis role="strong">2.</emphasis>  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: </para><itemizedlist><listitem override="none"><para><emphasis role="strong">a)</emphasis>       You must cause the modified files to carry prominent notices       stating that you changed the files and the date of any change. </para><para><emphasis role="strong">b)</emphasis>       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. </para><para><emphasis role="strong">c)</emphasis>       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.

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. </para><para>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. </para><para>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. </para><para><emphasis role="strong">3.</emphasis>  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: </para><itemizedlist><listitem override="none"><para><emphasis role="strong">a)</emphasis>       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, </para><para><emphasis role="strong">b)</emphasis>       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, </para><para><emphasis role="strong">c)</emphasis>       Accompany it with the information you received as to the offer       to distribute corresponding source code.

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". </para><para>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. </para><para><emphasis role="strong">1.</emphasis>  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. </para><para>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. </para><para><emphasis role="strong">2.</emphasis>  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: </para><itemizedlist><listitem override="none"><para><emphasis role="strong">a)</emphasis>       You must cause the modified files to carry prominent notices       stating that you changed the files and the date of any change. </para><para><emphasis role="strong">b)</emphasis>       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. </para><para><emphasis role="strong">c)</emphasis>       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.) </para></listitem></itemizedlist><para>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. </para><para>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. </para><para>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. </para><para><emphasis role="strong">3.</emphasis>  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: </para><itemizedlist><listitem override="none"><para><emphasis role="strong">a)</emphasis>       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, </para><para><emphasis role="strong">b)</emphasis>       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, </para><para><emphasis role="strong">c)</emphasis>       Accompany it with the information you received as to the offer       to distribute corresponding source code.

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. </para><para>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. </para><para><emphasis role="strong">4.</emphasis>  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. </para><para><emphasis role="strong">5.</emphasis>  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. </para><para><emphasis role="strong">6.</emphasis>  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. </para><para><emphasis role="strong">7.</emphasis>   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. </para><para>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. </para><para>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. </para><para>This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. </para><para><emphasis role="strong">8.</emphasis>  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.
