This works:

#!/usr/bin/env ruby
require "ostruct"
require "optparse"

options = OpenStruct.new

options.date = false

option_parser = OptionParser.new do |opts|
  opts.on("-d", "--date DATE", String, "Optional: Specify date in
format 00-00-00") do |date|
    options.date = date
  end
end

option_parser.parse!

puts "<#{options.date}>"

I had to add the DATE parameter in the long format specification and
also call parse!:

./test.rb -d "12-10-12"
<12-10-12>

Jesus.
