This is mostly true. I changed disp to simulavr-disp in the latest
release. There's also more options to increase or decrease the verbosity.
See `simulavr --help` for complete list.

:) Now gdb can connect to simulator (in gdbinit script (see below))
:) ddd --debugger avr-gdb --command gdbinit

This is exactly how I use it. Works well for me.

You no longer need to set the remote address size. ;-)

The load command is only needed if the program is not resident in the
remote target.  For avarice, the load command doesn't work yet.

If you have a complicated debug setup, it's too much work to do it 100
times correctly without a script. ;-)
