[Nix-dev] Announcing nix-exec

[Shea Levy]

Hi all,

I've just added [1] nix-exec to nixpkgs. It provides a way to define and
execute programs written in nix, for programs that need to interact with
the nix store or expression language. Please see the home page [2] for
more details.

Please note that this was a quick project, and that there are sure to be
bugs, inefficiencies, and lackluster documentation. I've only had time
so far to test one trivial example! So please open issues if something
isn't working right.

Happy hacking!

~Shea
