updatoo v0.3
Colaboração: Ricardo Iramar dos Santos
Data de Publicação: 10 de Fevereiro de 2009
updatoo é de um script em bash que automatiza o processo de atualização do Gentoo.
Se executado sem parâmetros updatoo irá atualizar sua árvore do portage com o
eix-sync, checar se o sistema já esta atualizado e por pacotes "problemáticos",
criar uma lista de pacotes que precisam serem atualizados e instalá-los,
removerá os pacotes desnecessários e executará revdep-rebuild.
Sugestões, criticas, bugs ... mande para <ricardo iramar (a) gmail com>.

#
# updatoo is a bash script that performing a simple full (silent if you
# want) update in a Gentoo System. By default updatoo will synchronize
# your portage tree with eix-sync, check if your system is update and for bad
# packages, create a pretend list of packages, try to install all the packages
# from the pretend list, clean up the system and run revdep-rebuild command.
# If occur any problem updatoo will abort with code 1 so you can combine
# with && or || operator. 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.

--clean (-c) Clean up the entire system.
--revdep (-r) Run revdep-rebuild command after all.
You can combine the options.
