| YACC is a Look-Ahead LR parser generator that takes Backus–Naur Form text files and generates LALR parsers from it. Primarily used as tool for generating front end parsers for compilers or formal validation for file formats in export filters and so on, so forth. | | * [http://dinosaur.compilertools.net/ Lex & YACC homepage] at Compilertools.net |

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 complement each other but are also useful on their own to a degree.
