 == Please make the introductory explanation of LALR parser....introductory == 

 I am making this request because Wikipedia is for public consumption, not just for us compugeeks.  The terminology and the complexity of the sentences in the introduction that a normal person would probably go catatonic trying to figure out what it meant and, if that didn't happen, they'd spend the next 6 years learning all the terminology necessary just to start to understand it.  A bit of hyperbole, actually, but I think you get my point.  PLEASE ""dumb down"" the explanation for the mere mortals.  Thanks!!!!  "
