Package jflex: Information

JFlex is a lexical analyzer generator (also known as scanner
generator) for Java, written in Java.  It is also a rewrite of the
very useful tool JLex which was developed by Elliot Berk at Princeton
University.  As Vern Paxson states for his C/C++ tool flex: They do
not share any code though.  JFlex is designed to work together with
the LALR parser generator CUP by Scott Hudson, and the Java
modification of Berkeley Yacc BYacc/J by Bob Jamison.  It can also be
used together with other parser generators like ANTLR or as a
standalone tool.
