 This package makes it easier to operate Detox from the command line. `detox-cli` should be installed globally, enabling usage of the command line tools outside your npm scripts. `detox-cli` is merely a script that passes commands through to a command line tool shipped inside `detox` package (in `node_modules/.bin/detox`).
