+.TH JFLEX "1" "October 2005"
+.SH NAME
+jflex \- a lexical analyzer generator (also known as scanner generator) for Java
+.SH SYNOPSIS
+.B jflex
+\fI<options> <input-files>\fR
+.SH DESCRIPTION
+JFlex is a lexical analyzer generator (also known as scanner generator) for Java(tm), written in Java(tm). It is also a rewrite of the very useful tool JLex. JFlex is designed to work together with the LALR parser generator CUP, and the Java modification of Berkeley Yacc BYacc/J. It can also be used together with other parser generators like ANTLR or as a standalone tool.
