The Zeus gdb debugger interface was added around about 2002 
so it is showing it's age ;)

The current plan is to first see if the current debugger support 
can be improved (i.e. made more user friendly) and once this is 
done I see no reason why support for GDB/MI can not be also added.

No. I did not know this.

In any case, because of the way the Zeus debugger interface 
in designed this doesn't matter greatly. 

In a nut shell each debugger DLL is nothing more than 
a mapping of Zeus debug actions to a debugger commands.

For example here is the list of Zeus debugger actions and 
how they are mapped to for the ddbg debugger:

   Action       ddbg Command
   =========================
   RUN          r
   CONTINUE     r
   STEP         in
   NEXT         ov
   UNTIL        out
   KILL         q
   UP           ii
   DOWN         dr
               
   ARGS         us
   STACK        ds
   PRINT        =
   PRINTEX      ii
   LOCALS       lsv
   HELP         ?
               
   BREAKSET     bp
   BREAKCLR     dbp
   BREAKALL     dbp *
   BREAKINFO    lbp

These are the defaults, but all these actions can also be re-configured 
by the user.
