-This cheat sheet attempts to lay out the fundamental elements of the Haskell
-language and libraries. It should serve as a reference to both those learning
-Haskell and those who are familiar with it, but maybe can't remember all
-the varieties of syntax and functionality.
 
-It is presented as both an executable Haskell file and a printable document. Load
-the source into your favorite interpreter to play with code samples shown.
