/*
* 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]
*
* It is necessary to do this (intead of using pac) because when npm installs
* a module, it will actually strip out the node_modules folder from the
* tarball unless bundleDependencies is set.
