	* This script will download a package (and all of its dependencies) from the
	* online NPM registry, then create a gzip'd tarball containing that package
	* and all of its dependencies. This archive can then be copied to a machine
	* without internet access and installed using npm.
	*
	* The idea is pretty simple:
	* - npm install [package]
	* - rewrite [package]/package.json to copy dependencies to bundleDependencies
	* - npm pack [package]
