Can you please explain the following to me? 
##  _get_commands (nil) : listref
#
#   each Machine has its own list of Commands that should be 
#   executed in response to the user's input.   this routine returns 
#   a reference to that list.

What prompted you to do that? What I expect is the following? 
=head1 FUNCTIONS ....

=head2 C<_get_commands (nil) : listref>

   each Machine has its own list of Commands that should be 
   executed in response to the user's input.   this routine returns 
   a reference to that list.

If you're going to bother writing more than two lines of documentation, please make it POD, that is what it is for.
