   5  * We reserve no LEGAL rights to the Purdue Compiler Construction Tool
   6  * Set (PCCTS) -- PCCTS is in the public domain.  An individual or
   7  * company may do whatever they wish with source code distributed with
   8  * PCCTS or the code generated by PCCTS, including the incorporation of
   9  * PCCTS, or its output, into commerical software.

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