FLEX: Fast Lexical Analyzer Generator

Fles is a tool for generating 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 - these are 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 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.
