I don't see in the code where the method retrieve is called, so I
would not expect ruby newrest.rb to do anything.
Also I don't see how the command line value id is being loaded into
$param. Normally for ruby command line args I use ARGV or
OptionParser. Google for ruby command line parameters and you will
find how to do it.
