-================================================================================
-
-Gentoo updates should normally be done manually in case an incorrectly done
-upgrade may render the system unusable. The purpose of these scripts is to do
-the same update across regions quickly.
-
-The plan is to manually do the update in one region and record the actions
-in ${architecture}/update_gentoo.sh. Once done these scripts can be used to
-replay it in the other regions.

-update_gentoo_64.sh
-
-Updates the latest 64-bit Dowd and Associates Gentoo Linux AMI. Will use a
-c1.medium instance for upgrade and t1.micro as a test instance.
-Because sudo will be called, this script cannot be run in the background.
-Recommend running screen before running.
-
-Takes 4 options:
-region 
-security group
-key pair
-keyfile
