In the USA and some many other jurisdictions you cannot violate any copyright license by running a program because copyright controls only the right to make copies and running a program does not do that. It may involve making temporary "ephemeral" copies such as the copy from disk to RAM: USA copyright law clarifies this by granting a specific exemption for running programs. Section 9 of the GPL makes this explicit and extends it to other jurisdictions. The license terms attached to a copy of a work by the copyright owner apply to all copies of that work made by others no matter what terms are attached to other works that it is subsequently attached to or embedded in. Note that if you make substantive changes it becomes a deriviative. -- John Hasler jhas...@newsguy.com Elmwood, WI USA
