Liskell docs, finally

As the ACM SIGPLAN template gave my Latex document much more space, I decided — instead of writing a separate piece of documentation — to enrich my ILC07 submission with more interesting chapters about meta-programming and the Liskell prelude. This paper is much richer in content as the original (about half the content is new) and it finally starts to explain the mechanisms behind defmacro and how you can use them in the Haskell/Liskell world. So if you are interested in Liskell, the revised paper certainly deserves a second look.
