move-cli/cli.js

The CLI implementation for andrewrk/node-mv. Like `fs.rename`, but works across devices, and works with directories. Think of the unix utility `mv`.

	Usage
	  $ move-cli source dest
	  
	Options
	  --md, --mkdirp    first create all necessary directories
	  --nc, --noclobber don't overwrite existing files
	  -l, --limit      how many concurrent file requests can be made, default 16
	  
	Example
	  $ move-cli source/file dest/file
