@@@STARTPACK(flex;fast lexical analyzer generator)
<P>
flex is a tool for generating scanners: programs which
recognize lexical patterns in text. flex reads the given
input files, or its standard input if no file names are
given, 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.
