/**
 * Script for publishing PUBLISHABLE_PACKAGES to npm. By default, this runs in tarball mode, meaning
 * the script will only print out what the contents of the files included in the npm tarball would
 * be.
 *
 * Please run this first (ie `yarn npm:publish`) and double check the contents of the files that
 * will be pushed to npm.
 *
 * If it looks good, you can run `yarn npm:publish --for-real` to really publish to npm. You must
 * have 2FA enabled first and the script will prompt you to enter a 2FA code before proceeding.
 * There's a small annoying delay before the packages are actually pushed to give you time to panic
 * cancel. In this mode, we will bump the version field of each package's package.json, and git
 * commit it. Then, the packages will be published to npm.
 *
 * Optionally, you can add the `--debug` flag to `yarn npm:publish --debug --for-real` to run all
 * steps, but the final npm publish step will have the `--dry-run` flag added to it. This will make
 * the command only report what it would have done, instead of actually publishing to npm.
