Description

# バージョンに迷ってredmineに登録していなかった[ruby-dev:35801]の件を
# redmineの方に入れておきます。

opts.onでオプションが重複していると--helpでは
先に出てきた方に対応するように表示されるのに
実際には後に出てきたの方の意味になります。

% cat o.rb
#!/usr/bin/ruby
require 'optparse'
ARGV.options do |opts|
  opts.on("-t", "--test-option"){p "test-option"}
  opts.on("-t", "--another-test-option"){p "another-test-option"}
  opts.parse!
end
% ruby18 -v o.rb -h
