- *\r
- * We encourage users to develop software with PCCTS. However, we do ask\r
- * that credit is given to us for developing PCCTS. By "credit",\r
- * we mean that if you incorporate our source code into one of your\r
- * programs (commercial product, research project, or otherwise) that you\r
- * acknowledge this fact somewhere in the documentation, research report,\r
- * etc... If you like PCCTS and have developed a nice tool with the\r
- * output, please mention that you developed it using PCCTS. In\r
- * addition, we ask that this header remain intact in our source code.\r
- * As long as these guidelines are kept, we expect to continue enhancing\r
- * this system and expect to make other tools available as they are\r
- * completed.\r
