How to add my portage as an overlay:

* emerge layman dev-util/git
* edit /etc/make.conf, add the following line at the bottom:
 source /usr/local/portage/layman/make.conf
* edit /etc/layman/layman.cfg, add the following overlay (read directions):

* Add my overlay
 layman -f -a bryan-portage

When you 'emerge --sync' you will also need to 
'layman -s ALL' to update your overlays.
Creating a script to do this might be the best idea:

----  sync.sh ----

#! /bin/sh
layman -s ALL
emerge --sync

----

Or, if you use eix:
---- sync.sh ----

#! /bin/sh
layman -s ALL
eix-sync

----

I personally add sync.sh to /etc/cron.daily/
