%description
    Flex is a tool for generating scanners: programs which recognize
    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 C function 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.
