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

        http://www.gnu.org/software/bison/bison.html
        http://www.gnu.org/manual/bison/index.html
        http://www.gnu.org/software/flex/flex.html
        http://www.gnu.org/manual/flex-2.5.4/flex.html


http://www-4.ibm.com/software/developer/library/pirates4/index.html?dwzone=linux
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. :)

The opinions expressed by me are not necessarily opinions. In all
probability, they are random rambling, and to be ignored. Failure to ignore
may result in severe boredom or confusion. Shake well before opening. Keep
Refrigerated.
