    Usage
       $ ./index.js <input>
       $ ./index.js -s <status>
       $ ./index.js <input> --emoji=<emoji>

    Options
       --status, -s  status based on presets [lunch, afk, off, meeting, etc. - see config.js]
       --timeout, -t  how long status lasts before clearing  (in minutes)
       --emoji, -e  manually set the emoji for slack status (cannot be used with 'status')
