Ruby LOADPATH cheatsheet

gistfile1.rb

#loadfile:
$:
$LOAD_PATH

require File.join(File.dirname(__FILE__), "foo", "bar") #=> "file/foo/bar"
#or
require File.expand_path(File.join(File.dirname(__FILE__), "foo", "bar"))
#=> "path/to/file/foo/bar"

require "foo/bar" #=> relative to loadpath, do this in relative files

#ruby treat 3 require differently, might over load
