%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.
