The Selector, Command Handler and Menu Handler are the heart of the Diagnostic Software and will be referenced
as the Diagnostic Engine in the context of this document. They form a framework in which Diagnostic Nuclei and
standard Scripts can be added via a well-defined software interface. The actual contents of the Menu Handler are part
of the FDS.
