Mandatory options with optparse
I was playing with optparse (great stuff ;)) and I didn't see how to check =
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 =3D OptionParser.new do |opts|
opts.banner =3D "My silly example"
opts.on("-m", "--message MESSAGE", "A message to show") do |m|
options.message =3D m
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!

There is no suck way. I had thought about the idea like it
formerly, but concluded that it's easy to read and write in
ruby, rather than in mini-DSL.
