I'm having trouble with this "enable" word. To me it means to make able, or 
to make possible, in the manner of opening a gate; but I often get the 
distinct impression that it's being used forcefully, in the manner of being 
pushed through the gate. /etc/init.d/numlock is a case in point - it says 
it's enabled numlock when in fact it's set it.

So if the man page says that "it's only enabled with -O<whatever>" I infer 
that it has no effect in the absence of -O? and therefore need only be 
specified  if -O? is present. Is that what you two mean? I suspect you mean 
'forced' rather than 'enabled'.

I don't mean to appear pedantic, but I need help here :-(
