Subject: Mandatory options with optparse

Hi all,

I was playing with optparse (great stuff ;)) and I didn't see how to check if 
a mandatory option have been supplied (note that I say mandatory *option*, 
not mandatory *argument*).

So, if I got the next chunk of code:

opts = OptionParser.new do |opts|
  opts.banner = "My silly example"

  opts.on("-m", "--message MESSAGE", "A message to show") do |m|
    options.message = m
  end
end

I figured out that I'd must check it by my own (if options.message.nil?...), 
but I only wanna know if there's a "optparse-way".

Thanks in advance!
