/* Amber package loading.
  Load this script as well as require.js (works in any order;
    either defines 'require', thus passing config, if loaded prior require.js;
    or calls require.config, if loaded post require.js).
  Usage example:
    require(['amber/devel'], function(smalltalk) {
        smallralk.initialize();

        smalltalk.Browser._open();
    });
  For detailed explanation of amber loading, see:
  https://github.com/amber-smalltalk/amber/wiki/How-to-load-amber
