|
|
* 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.
