+# fritteli's Gentoo overlay
 Gentoo overlay with some ebuilds that I found either outdated or missing in the official repository or in other overlays. Ebuilds are usually removed from this overlay whenever I find a version available in the official tree or in another overlay (provided I'm satisfied with them).

 You may adapt the `location` attribute to your system's own setup.
 
 If you prefer to use the overlay hostet at GitHub (which tends to be more stable but less up-to-date than the one hosted at gittr.ch), you may use `https://github.com/fritteli/gentoo-overlay.git` for the `sync-uri`.
