Examples from The Little Schemer ported to Ruby (and scheme).
Examples from the book "The Little Schemer" ported to Ruby. Get the book: http://www.amazon.com/Little-Schemer-Daniel-P-Friedman/dp/0262560992 The scheme examples work with the PLT scheme interpreter (http://plt-scheme.org/). I'm using that one because I really don't know any better. If there's a better one, please let me know.
