      This means I didn't find a _templates folder right here, 
      or anywhere up the folder tree starting here.

      Here's how to start using Hygen:

      $ hygen init self
      $ hygen with-prompt new --name my-generator

      (edit your generator in _templates/my-generator)

      $ hygen my-generator 

      See http://hygen.io for more.

  Object.entries(availableActions(templates)).forEach(([k, v]: [any, any]) => {
    logger.log(`${chalk.bold(k)}: ${v.join(', ')}`)
  })
}

export { availableActions, printHelp, VERSION }
