They use a change to the monitor code I have made. The change to the
monitor is to allow a new command to be registered at runtime.

The commands I have ported from BSD are run as functions on the monitor
task not separate tasks.

Look for :

 int rtems_monitor_insert_cmd(rtems_monitor_command_entry_t *);
 int rtems_monitor_erase_cmd(rtems_monitor_command_entry_t *);

in monitor.h in the lastest snapshots.

I did not know this had been listed on the web site.

In time the monitor can be transformed into more of a shell, say
`eshell'. It would be nice to have the commands linked to the
filesystem. This provide a structure to commands which is currently not
present and missing. You add a few commands, type help and swamped with
a long list.
