Yes, it sucks. That’s why I wrote the ‘getopt’ package.

gem install getopt 🙂

require ‘getopt/long’  
include Getopt

opts = Getopt::Long.new([’-d’, ‘–date’, REQUIRED])

if opts[‘d’]

# …

end

nice dan. i’ve been using optparse for all my stuff but it’s usage is a  
bit  
obtuse. perhaps i’ll switch… does it support parsing arbitrary arrays  
or  
only ARGV?

regards.

I am having an issue with the script working. Is their some path  
variable  
that needs to be set for ruby to see the gem packages?

Initially i have the ubuntu ruby pkgs installed. I have removed them and  
built ruby 1.8.4 and gems 0.8.11 built from source.

Any ideas?
