+reads a grammar specification and converts it to a Java program that can
+recognize matches to the grammar.  In addition to the parser generator itself,
+JavaCC provides other standard capabilities related to parser generation such
+as tree building (via a tool called JJTree included with JavaCC), actions,
+debugging, etc.")
