Here is some info on my personal Gentoo portage overlay.
You can browse it online via the VCS module.
To check out the whole overlay either use layman:
layman -f -o http://gimpel.ath.cx/~tom/layman-gimpel.list -a gimpel
or use SVN directly:
svn co http://gimpel.ath.cx/svn/gimpel/
Most of the ebuilds here provide bleeding edge stuff, including very latest versions and live SVN/CVS ebuilds, mainly multimedia related.
- Avidemux 2.4 preview and SVN (2.4 branch), with optional cmake build system
- Audacious SVN + audacious-plugins SVN
- tovid SVN (works with wxpython-2.8 - also in the overlay)
- Xmms2 snapshot and SVN
- SMplayer latest and SVN
- VLC from SVN
.. and a lot more.
Some things are maybe not correctly keyworded due to lazyness or whatever, so please take a bit care when checking out the full overlay.
The changelog can be found here.
