Figure out the text format you want your users to type the value on the command 
line, write a function that will take that text and convert it to an array or 
list, then customize OptionParser to use that parser as given in the link above. 
Keep in mind that your user probably won't want to need to use whitespace or any 
kind of brackets. Commas are nice, though.

You may also want to consider taking a filename and parsing that file instead.
