Ruby 1.9’s relative_relative for Rubinus and MRI 1.8
Here we add in Module RequireRelative method: require_relative, and abs_file. Example:
require 'rubygems'; require 'require_relative' require_relative './lib/foo' absolute_path = RequireRelative.abs_file
But why abs_file? Well, recall that __FILE__ does not give an absolute path. So if you have chdir’d before using __FILE__, you might not be able to retrieve the full path.
