	help: '''
		Use this command to sync your local changes to a certain device on the fly.

		The `source` argument can be either a device uuid or an application name.

		You can save all the options mentioned below in a `resin-sync.yml` file,
		by using the same option names as keys. For example:

			$ cat $PWD/resin-sync.yml
			source: src/
			before: 'echo Hello'
			ignore:
				- .git
				- node_modules/
			progress: true

		Notice that explicitly passed command options override the ones set in the configuration file.

		Examples:

			$ resin sync MyApp
			$ resin sync 7cf02a6
			$ resin sync 7cf02a6 --port 8080
			$ resin sync 7cf02a6 --ignore foo,bar
