An excellent, fast tool that negates the need to use emerge to search for packages.

To install simply

emerge -av app-portage/eix

You can use eix to synchronise portage and layman overlays by adding the following line to /etc/eix-sync.conf

echo '*' >> /etc/eix-sync.conf

To actually perform the sync and update the eix' database simply <code> eix-sync </code> If you want to search all Layman overlays with eix for available packages then simply <code> eix-remote update </code> Now eix'' will tell you what overlay packages that meet your search criteria are from.
