+	help
+	  A fast lexical analyzer generator
+
+	  Flex is a tool for generating scanners: programs which
+	  recognized lexical patterns in text. It reads the given
+	  input files for a description of a scanner to generate. The
+	  description is in the form of pairs of regular expressions
+	  and C code, called rules. Flex generates as output a C
+	  source file, lex.yy.c, which defines a routine yylex(). This
+	  file is compiled and linked with the -lfl library to produce
+	  an executable. When the executable is run, it analyzes its
+	  input for occurrences of the regular expressions. Whenever
+	  it finds one, it executes the corresponding C code.
+
+	  The behaviour of Flex has undergone a major change since
+	  version 2.5.4a. Flex scanners are now reentrant, and it is
+	  now possible to have multiple scanners in the same program
+	  with differing sets of defaults, and the scanners play nicer
+	  with modern C and C++ compilers. The Flip side is that Flex
+	  no longer conforms to the POSIX lex behaviour, and the
+	  scanners require conforming implementations when flex is
+	  used in ANSI C mode.
