- * 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.
