CLI · Babel

http://babeljs.io/docs/usage/cli

How to use the CLI tools. Babel comes with a built-in CLI which can be used to compile files from the command line. Install Babel CLI globally on your machine, it’s much better to install it locally. There are two primary reasons for this. Different projects on the same machine can depend on different versions of Babel allowing you to update one at a time. It means you do not have an implicit dependency on the environment you are working in. Making your project far more portable and easier to setup.
