* We encourage users to develop software with PCCTS. However, we do ask

* we mean that if you incorporate our source code into one of your

* addition, we ask that this header remain intact in our source code.
* As long as these guidelines are kept, we expect to continue enhancing
* this system and expect to make other tools available as they are
* completed.
