This repo is designed to be a nice way to work through The Little Schemer. You'll create a new file per chapter, add it to the table of contents (toc.rkt), and load your code into the REPL with ./schemer.sh.
You'll need Racket and Rlwrap installed. Racket is a modern, Scheme-like language. Rlwrap is a readline wrapper that gives you command history, among other things. You can install them both with Homebrew.
brew install racket
brew install rlwrap
./schemer.sh
