http://www.gnu.org/software for flex and bison (they also have excellent 'info'
pages, type 'info flex' or 'info bison'), specifically:


is the article for pirates ho, it talks about using lex/yacc to make a
scripting language engine.

there are lots of university type resources available on the web, and several
books that talk about using them. Basically any documentation on making
compilers or interpreters will be useful... (the first part of compiling is to
check the syntax and build a data structure to represent the semantics in a
machine friendly way... parse trees and stuff) 

I personally found the info pages to be incredibly useful, and would use those
to start off with. :)
