Grab Feature :

if you want to run this kind of command line :

``bash
node myScript.js --name Ahmed --action greeting
`
Then , reading values of arguments(i.e : --name, --action ) is wanted .

If so ,this package is useful :

`js
var grab=require('ps-grab');
grab('--name') // return 'Ahmed'
grab('--action') // return 'greeting'
``
