Summary: A fast lexical analyzer generator

Description: 

flex is a tool for generating scanners: programs which recognized lexical
patterns in text.  flex 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, you may have multiple
scanners in the same program with differing sets of defaults, and
they 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.  The package flex-old provides the older behaviour.
