What this code lines mean? Especially $:. before the unshift?
$:.unshift File.join(File.dirname(__FILE__),'..','lib')

ruby comes with a set of predefined variables
$: = default search path (array of paths) __FILE__ = current sourcefile
if i get it right (not 100% sure) this adds the lib path to this array of search paths by going over the current file. which is not exactly the best way, i would simply start with RAILS_ROOT (at least for a rails project)
