  Comments:
  GDB/MI commands for the "Breakpoint Table Commands" section.@p

@<pre>
gdb command:          Implemented?

-break-after          Yes
-break-condition      Yes
-break-delete         Yes
-break-disable        Yes
-break-enable         Yes
-break-info           N.A. (info break NUMBER) (*)
-break-insert         Yes
-break-list           No (*)
-break-watch          Yes
@</pre>

(*) I think the program should keep track of the breakpoints, so it will
be implemented when I have more time.@p
