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 dis- tribution, a complete
c)Accompany it with the information you received as to the offer to distribute cor- responding source code. (This alternative is allowed only for noncommercial distrib- ution and only if you received the pro- gram 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 con- tains, plus any associated interface defin- ition files, plus the scripts used to control compilation and installation of the exe- cutable. However, as a special exception, the source code distributed need not include anything that is normally distrib- uted (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 exe- cutable.
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 dis- tribution 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 compli-
ance.
5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permis- sion 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 dis- tributing 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 licen- sor to copy, distribute or modify the Program subject to these terms and con- ditions. 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 judg- ment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agree- ment 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 perti- nent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit
It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest
