License

The license for PBS derived programs allows redistribution accompanied by information on how to obtain the source code and modifications, and requires an acknowledgement in any advertising clause mentioning use of the software (compare the

). Prior to 2002, PBS and derivative programs (OpenPBS) prohibited commercial redistribution of the software, required registration at the OpenPBS website, and required attribution when PBS contributed to a published research project. These requirements, which did not meet the Open Source Initiative's definition of open source, were set to expire on December 31, 2001.
