Thanks, nice script Roy.  With the ewarn and eerror additions above 
you get even more information.

I use the following in root's crontab:
# sync Gentoo nightly and check for updates
0 0 * * 1-6 /usr/sbin/esync -ns && /usr/bin/update-eix -q 
&& /usr/bin/emerge world -uNvplt && /usr/local/bin/einfo -uN world
# sync Gentoo weekly and check (deep) for updates
0 0 * * 7 /usr/sbin/esync -ns && /usr/bin/update-eix -q 
&& /usr/bin/emerge world -uNDvtpl && /usr/local/bin/einfo -uND 
world
