* The original source for this file is:
* https://github.com/mozilla/gcli/
*
* This build of GCLI for Firefox comes from 4 bits of code:
* - prefix-gcli.jsm: Initial commentary and EXPORTED_SYMBOLS
* - console.js: Support code common to web content that is not part of the
* default firefox chrome environment and is easy to shim.
* - mini_require: A very basic commonjs AMD (Asynchronous Modules Definition)
* 'require' implementation (which is just good enough to load GCLI). For
* more, see http://wiki.commonjs.org/wiki/Modules/AsynchronousDefinition.
* This alleviates the need for requirejs (http://requirejs.org/) which is
* used when running in the browser. This code is provided by dryice.
* - A build of GCLI itself, packaged using dryice
* - suffix-gcli.jsm - code to require the gcli object for EXPORTED_SYMBOLS.
*
* See gcli.js for more details of this build.
* For more details on dryice, see the https://github.com/mozilla/dryice
