  Usage: node ./scripts/template/initialize.js [OPTIONS]

  Bootstraps and runs \`react-native init\`, using the currently checked out
  repository as the source of truth for the react-native package and
  dependencies.

  - Configures and starts a local npm proxy (Verdaccio).
  - Builds and publishes all in-repo dependencies to the local npm proxy.
  - Runs \`react-native init\` with the local npm proxy configured.
  - Does NOT install CocoaPods dependencies.

  Note: This script will mutate the contents of some package files, which
  should not be committed.

  Options:
    --projectName      The name of the new React Native project.
    --templatePath     The absolute path to the folder containing the template.
    --directory        The absolute path to the target project directory.
