Here it is.  After reading Matt's post, looks like I need to try
dispatch-conf instead of etc-update.  Learn something new
everyday here.  ;-)

Disclaimor, these scripts are starting points.  Customization
is highly recommended.  :-)

Scripts:

/etc/cron.daily/portage.cron
/usr/local/sbin/einfo

Have fun,
Roy
