I usually have one script that kicks off a program based in an  
external file of definitions. And that script looks like:

require 'foo.rb'
Program::start()

That sort of thing.  I usually use that first file to do things like  
set up the environment, read parameters, etc.... then pass them to  
the rest of the program.

Check out how "irb" works.  Basically that idea.
