		'Start a remote build on the resin.io cloud build servers or a local mode device',
	help: stripIndent`
		This command can be used to start a build on the remote
		resin.io cloud builders, or a local mode resin device.

		When building on the resin cloud the given source directory will be sent to the
		resin.io builder, and the build will proceed. This can be used as a drop-in
		replacement for git push to deploy.

		When building on a local mode device, the given source directory will be built on
		device, and the resulting containers will be run on the device. Logs will be
		streamed back from the device as part of the same invocation.

		Examples:

			$ resin push myApp
			$ resin push myApp --source <source directory>
			$ resin push myApp -s <source directory>

			$ resin push 10.0.0.1
			$ resin push 10.0.0.1 --source <source directory>
			$ resin push 10.0.0.1 -s <source directory>
