+ * $Id$
+ * <p>
+ * We reserve no legal rights to the ANTLR--it is fully in the
+ * public domain. An individual or company may do whatever
+ * they wish with source code distributed with ANTLR or the
+ * code generated by ANTLR, including the incorporation of
+ * ANTLR, or its output, into commerical software.
+ * <p>
+ * We encourage users to develop software with ANTLR. However,
+ * we do ask that credit is given to us for developing
+ * ANTLR. By "credit", we mean that if you use ANTLR or
+ * incorporate any 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 ANTLR and have
+ * developed a nice tool with the output, please mention that
+ * you developed it using ANTLR. In addition, we ask that the
+ * headers 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.
