# This script wraps Eric Hammond's ec2ubuntu-build-ami script ( http://alestic.com/ )
# It passes all args directly to the ec2ubuntu-build-ami script, except for three
# which it modifies to the following values:
# --distribution ubuntu
# --codename intrepid
# --script /mnt/ec2onrails/server/rakefile-wrapper
# Other than those three args (which will be ignored if given) this script should
# be given the regular ec2ubuntu-build-ami args, for details see the comments at:
# http://ec2ubuntu.googlecode.com/svn/trunk/bin/ec2ubuntu-build-ami
