#initialize(command_line_args) ⇒ Deployments

Initialize the deployment uploader with command line args. Use -h to see options. When command_line_args is a hash, we are invoking directly and it’s treated as an options with optional string values for :user, :description, :appname, :revision, :environment, :license_key, and :changes.

Will throw CommandFailed exception if there’s any error.
