Others will correct me if I'm wrong, but as I understand it: a Module is an 
actual Ruby construct... essentially a class with no instances. A library 
is a container file for bits of code. You would load the library using a 
command like:

  require 'my_lib'

The library file, my_lib.rb, could contain a Module or a Class or more than 
one of either or both. The program treats required files as though you had 
typed them in then and there.
