Upgrade Gentoo script

[sidusnare]

I have a script that I wrote, it evolved from a script to try and brute force upgrades while unattended into a script that I use to do Continuous Integration on a daily basis.

There are probably many scripts like it, but this one is mine.
I thought I would share to help those interested and get feed back:

I recommend you /join #bash on IRC: chat.freenode.net and ask for a code review.

They'll explain everything in patient detail, so long as you read the urls they give you before asking the next question.

Where is the chance to see the Changelogs for Gentoo revisions especially? For example if there only is a gcc-5 patch I don't update the software, because I use a stable toolchain for my personal Gentoo~unstable 'distribution'. Thus gcc-5 is not an issue for me at the moment. Where can I adapt new USE flags if they pop up with new releases of applications? Also: if there is a new mainNumber.Zero release I prefer to stabilize the software for the time being....
