453. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable formunder 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 theterms 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 yourcost of physically performing source distribution, a complete machine-readable copy of the corresponding sourcecode, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for softwareinterchange; or,c) Accompany it with the information you received as to the offer to distribute corresponding source code. (Thisalternative is allowed only for noncommercial distribution and only if you received the program in object code orexecutable 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 definitionfi les, 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) withthe major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless thatcomponent itself accompanies the executable.If distribution of executable or object code is made by offering access to copy from a designated place, then offeringequivalent access to copy the source code from the same place counts as distribution of the source code, even thoughthird 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. Anyattempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate yourrights under this License. However, parties who have received copies, or rights, from you under this License will nothave 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 permissionto modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept thisLicense. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate youracceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Programor works based on it.6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives alicense from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. Youmay not impose any further restrictions on the recipients’ exercise of the rights granted herein. You are not responsiblefor 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 topatent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict theconditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as tosatisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequenceyou may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution ofthe Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy bothit 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 thesection 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 contestvalidity of any such claims; this section has the sole purpose of protecting the integrity of the free software distributionsystem, which is implemented by public license practices. Many people have made generous contributions to the widerange of software distributed through that system in reliance on consistent application of that system; it is up to theauthor/donor to decide if he or she is willing to distribute software through any other system and a licensee cannotimpose 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 copyrightedinterfaces, the original copyright holder who places the Program under this License may add an explicit geographicaldistribution limitation excluding those countries, so that distribution is permitted only in or among countries not thusexcluded. 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 totime. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problemsor concerns.Each version is given a distinguishing version number. If the Program specifies a version number of this License whichapplies to it and “any later version”, you have the option of following the terms and conditions either of that version or ofany later version published by the Free Software Foundation. If the Program does not specify a version number of thisLicense, 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 tothe Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals
