I also kind of misread MatthewPhillips post and thought he was looking for Emacs instructions. For sending code to the browser from a normal REPL, (started with `lein repl`) I think a good place to start is these two files from Cljs One:
https://github.com/brentonashworth/one/blob/master/src/app/c...
https://github.com/brentonashworth/one/blob/master/src/lib/c...
Together they should help in setting this up for a vanilla Cljs project, or require them in your fork of Cljs One and start a REPL.
