[prog] lex and yacc

[Sue Stones]

Does anyone know how to use lex and yacc, I am trying to get started at 
understanding them (although I dunno how they will be usefull in the future).

Anyway at the moment I am stuck trying to get an overview.  I am trying to 
write a compiler for a "bare bones" programming language but I cannot uite 
get my head around what I am trying to achive, and how lex and yacc work 
together.

If you have any insight about this process works I would love to hear them.
