- * SOFTWARE RIGHTS
- *
- * We reserve no LEGAL rights to the Purdue Compiler Construction Tool
- * Set (PCCTS) -- PCCTS is in the public domain. An individual or
- * company may do whatever they wish with source code distributed with
- * PCCTS or the code generated by PCCTS, including the incorporation of
- * PCCTS, or its output, into commerical software.
- *
- * 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
- * acknowledge this fact somewhere in the documentation, research report,
- * etc... If you like PCCTS and have developed a nice tool with the
- * 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.
