Here is a place to explain what the change is about, how to
reproduce and observe the symptom, why the current code behaves the
undesirable way, etc. and then propose how to fix it.

Style--useless {braces} around a single-statement block.

Style--downcase "O" in "Option".

N_() merely marks the string for translation, but yields the string
as-is to the calling function (i.e. usage()).  You probably meant to
use _() instead.
