Subject: simple optparse question on available options

Hello,

I'm using optparse for a cli script. I need an argument (-s, --sort) to accept only 3 possible options :date, :country, :ipfreq, so here is my piece of optparse code:

[...]

# http://ruby.about.com/od/advancedruby/a/optionparser2.htm
  options[:sort] = :yes # <--- Not sure what this does, probably sets a default value to :sort ... I just grab the code sample from the link above
  
opts.on('-s', '--sort OPT', [:date, :country, :ip], 'Sorts by [date, country, ip-frequency]') do |sort|
    options[:sort] = sort
 end

[...]

Now I don't understand how to use this code in my exec function:


[...]
if File.exists?($logfile)
 	$f2b = F2bread.new($logfile)
	if options[:info]
		$f2b.info
        # opts.on('-s', '--sort OPT', [:date, :country, :ip], 'Sorts by [date, country, ip-frequency]') do |sort|
	elsif options[:sort]
		if options[:sort] == 'date'
			$f2b.sort_by_date
		elsif options[:sort] == "country" # <--- something like this?
			# etc...
[...]

Any sort of hints are always welcome.

Best regards,
