This is my personal gentoo overlay, containing new ebuilds written by me and modified ebuilds from other sources with bugfixes or similar.
Using this overlay is easy.
Make sure you have layman installed, using the git USE-flag, and set up, e.g. as described here.
After that you just have to add this overlay using:
layman -o "http://raw.github.com/tg--/gentoo-tg/master/overlay.xml" -f -a tg
That's it!
