 The Plan
 --------
 
 I think that the following steps should be done (in this order):
 
-# Declare the required classes to describe SMPP and SMPP PDU
-# Design an architecture which allows generic generation of PDU
-# Based on this, design the rest of the software

 Everything shall be unit tested.
