/**
 * This script is in charge of cleaning the `shrinkwrap` file.
 *
 * `npm shrinkwrap` has a bug where it will add optional dependencies
 * to `npm-shrinkwrap.json`, therefore causing errors if these optional
 * dependendencies are platform dependent and you then try to build
 * the project in another platform.
 *
 * As a workaround, we keep a list of platform dependent dependencies in
 * the `platformSpecificDependencies` property of `package.json`,
 * and manually remove them from `npm-shrinkwrap.json` if they exist.
 *
 * See: https://github.com/npm/npm/issues/2679
