| '''Lex''' is a tool that looks for logical units (lexemes) in sequences of characters. This is typically the first tasks a compiler does after it has when he is has to do is read the source program and group its characters into lexemes.

Lex and yacc are parser generating tools originally developed for the MULTICS operating system, basically Lex does lexical analysis while Yacc handles syntax analysis. The two are always distributed together and compliment each other but are also useful on their own to a degree.
