For example:

    option :minutes do
        short '-m'
        long '--minutes=MINUTES'
        desc 'Show entries within the specified last MINUTES'
        action { env = env + "&minutes=" + :value }
    end

It's cleaner to do this one-time translation in the associated action code instead of later. At this point,
Choice.choices[:minutes] is not available.

You may use:
action do |value| do_something(value); end

Same as with filter.
