Para quem está cansado de executar os mesmos comandos para atualizar o gentoo, este script automatiza o processo e não para de instalar os demais pacotes caso algum falhe.

# Agent Smith (Ricardo Iramar dos Santos)

#
# updatoo is a bash script that performing a simple full update in a Gentoo System.
# You can run updatoo in two ways:
# 1. Without parameter (default) that it will ask you for confirmation in every step.
# 2. With --force (-f) that it won't ask you for anything.
# Basically updatoo will synchronize your portage tree with eix-sync, create a pretend list of packages and install them.
# If occur a problem the updatoo is aborted with code 1.
# Everything is loged in /root/.updatoo/ where you can check anytime.
# Please report any bug to ricardo.iramar@gmail.com or http://forums.gentoo.org/viewtopic-t-717092.html.
#
# ChangeLog
# Version 0.1 (29/11/2008)
# - First version. No bugs yet.
#
# Version 0.2 (07/12/2008)
# - Gentoo look output (/etc/init.d/functions.sh").
# - Some code fix.
#
# ToDo
# - Detect masked packages.
# - Test mode (do nothing, just create the lists).
# - E-mail notification.
