Rename admin menu items in SilverStripe

SilverStripe 3.0.x cheap trick of the week:

If you want to rename a menu item in the SilverStripe Admin Area, because f.e. you find “Security” or “Sicherheit”(since we are german ;)) a too harsh wording and you prefer “Members” or “Benutzer”:

Add a lang folder in your project folder and add the language file:
de.yml or en.yml and place your wording:

Flush the cache, call the admin area again and you will see the menu item with changed wording.

Thanx to UndefinedOffset from IRC for the advise :)

In SilverStripe 2.4 overriding language files doesnt seem to work.
What you can do here is remove & add the menu item via config:
