 * 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,

 * developed a nice tool with the output, please mention that
 * you developed it using ANTLR. In addition, we ask that the
