I use:

def which(libname)
  $:.each { |d|
    f = File.join(d, libname)
    p f if File.exists? f
    f += ".rb"
    p f if File.exists? f
  }
  nil
end

Is there an easy way to discover the path to a "require"-ed module
(assuming it's a .rb file)?

Ie, is there some way to find out where the interpreter would find
fred.rb if I said 

  require 'fred'

TIA
