rule-engine

Hi, I have a rough understanding of how the compilers work (I mean languages, grammars, lexical analysis, parsing etc). The rule engines have various rules and associated action, just like you have rules in the grammars and you can associate actions with them in parser-generator tools like ANTLR. So I am a bit confused on how to differentiate between these two. Could anyone give a clearer, more formal explanation for the differences ?

Thanks, Abhinav.
