Notify the user if there is an available update For this we use the `update-notifier` module with its default settings. This module will print a nice banner prompting the user to run the corresponding npm command to update. 2015-08-18 12:53:06 +00:00			`updateNotifier = require('update-notifier')`
Don't check for available updates when running as root `update-notifier` persist its update check results in a file, which is then read when running again the application. If this file gets written when the application is being run as root, we get ugly EPERM issues. 2015-08-20 20:54:22 +00:00			`isRoot = require('is-root')`

Improve the way the update notifier is shown Current has the following problems: - Our custom message gets printed even if the notifier doesn't contain an update. - The notifier box is deferred, therefore it's printed at the end of the command. Since our custom message is printed at the beginning, it makes no sense at all. 2015-10-15 13:18:45 +00:00			`notifier.notify(defer: false)`
