"""jdi: Just do it

This program can be used as an emc "DISPLAY".  It resets estop, turns the
machine on, loads and runs the ngc file (which must be given as a positional
argument), printing the sequence number and location once per second.  When
it's done it punches the ESTOP button and exits emc.
