                    <'otherwise to copy, modify, sublicense or distribute the Program is\n'> <'void, and will automatically terminate your rights under this License.\n'> 
                    <'However, parties who have received copies, or rights, from you under\n'> <'this License will not have their licenses terminated so long as such\n'>

                    <'signed it.  However, nothing else grants you permission to modify or\n'> <'distribute the Program or its derivative works.  These actions are\n'> 
                    <'prohibited by law if you do not accept this License.  Therefore, by\n'> <'modifying or distributing the Program (or any work based on the\n'>

                    <'the Program or works based on it.\n'> <'\n'> <'  6. Each time you redistribute the Program (or any work based on the\n'>

                    <'infringement or for any other reason (not limited to patent issues),\n'> <'conditions are imposed on you (whether by court order, agreement or\n'>

                    <'distribute so as to satisfy simultaneously your obligations under this\n'> <'License and any other pertinent obligations, then as a consequence you\n'> 
                    <'may not distribute the Program at all.  For example, if a patent\n'> <'license would not permit royalty-free redistribution of the Program by\n'> 
                    <'all those who receive copies directly or indirectly through you, then\n'> <'the only way you could satisfy both it and this License would be to\n'>

                    <'such claims; this section has the sole purpose of protecting the\n'> <'integrity of the free software distribution system, which is\n'> 
                    <'implemented by public license practices.  Many people have made\n'> <'generous contributions to the wide range of software distributed\n'> 
                    <'through that system in reliance on consistent application of that\n'> <'system; it is up to the author/donor to decide if he or she is willing\n'> 
                    <'to distribute software through any other system and a licensee cannot\n'> <'impose that choice.\n'> <'\n'>
