/*
   This file aggregates all the scripts needed for the Eloquent
   JavaScript book. First comes the MochiKit library, then some
   scripts related to the in-browser JavaScript editor (a more
   polished version of which can be found at
   http://marijn.haverbeke.nl/codemirror/), and finally some
   scripts specifically for mangling the layout of the pages of this
   book (book.js), and adding a console to it (initenv.js, env.js).
