Flexibly load ruby files. This gem will automatically add File.expand_path(File.dirname(__FILE__) + "/my_mod/my_file") with a simple declaration. Uses non-obtrusive methods - it won't polute Object or Kernel (although you are free to, if you so choose). This also allows you to switch between require, load, and autoload on a project wide basis.
