[Nix-dev] Proper way of adding custom nix expressions

[Marc Weber]

You can use hack-nix instead, it packages everything found on hackage.

The alternative is patch nixpkgs and contribute the missing packages.
The Nix wiki should talk about both way - I maintain the hack-nix way
only.

If you have trouble about hack-nix contact me. I can provide access to
an SSH account so that you can give hack-nix a try before setting it up
on your system.

Yours
