snipped non-LIRC commands

I use the command:

/usr/local/bin/irexec -d /home/mythtv/.lircrc

which provides the name of the LIRC config to use and daemonises
irexec (ideal for running irexec from a startup script). Check to make
sure your ~/.lircrc (which is the default file used if you don't
specify one) contains the POWER config (or is symlinked to the MythTV
file).
