Garrick's answer is a bit more ethereal... I'll try to be a bit more  
concrete.

Yes, this is supposed to be a command-line tool, but your ruby code  
(excluding the lack of quotes) looks like a good design start. One way  
to structure this is to add a 'bin' dir with 'powergrep' inside (or  
powergrep.rb--whatever). That code would look something like:

require 'powergrep'

grep = Powergrep.new

# process options / set stuff up

grep.run *ARGV

That way you can write easily testable code but still have command- 
line ease of use.
