//  Project: This is a debug DD intended for internal linking into aqsis.
//
//  Description: 
//    This DD is intended for internal linking into Aqsis. It is intended as
//    a debugging aide to support a completely static build of Aqsis suitable
//    for debugging in situation where dynamic linking causes problems
//      The intent is to behave as much like a real dd as possible, without doing
//    anything useful
