Rails - Feb 2008 - $:.unshift File.join(File.dirname(__FILE__),'..','lib')?

What this code lines mean? Especially $:. before the unshift?

$:.unshift
File.join(File.dirname(__FILE__),''..'',''lib'')

Regards,
Mohsin

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)
