That's my package collection based on Nix, mainly serves two purposes:
- Manage a shared set of configuration files to use on different machines, by installing johbo-config.
- Provide custom packages which are not in nixpkgs.
- Needs the Nix package manager, make sure to check out http://nixos.org and set it up.
- Needs a recent version of nixpkgs, at least follow the unstable channel. If that's not recent enough, either wait or use the master branch of nixpkgs.
