+ * ATokPtrImpl.h (formerly ATokPtr.cpp)
+ *
+ * This is #included in ATokBuffer.cpp for historical reasons.
+ * It has been renamed because of problems with the .cpp extension
+ * when used with IDE.
+ *
+ *
+ * ANTLRToken MUST be defined before entry to this file.
+ *
+ * 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.
