+ *
+ * We encourage users to develop software with PCCTS. However, we do ask
+ * that credit is given to us for developing PCCTS. By "credit",
+ * we mean that if you incorporate our source code into one of your
+ * programs (commercial product, research project, or otherwise) that you

+ * output, please mention that you developed it using PCCTS. In
+ * 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.
