xkeystone: Is it needed?

[matthiasbeyer]

Issue description

Found xkeystone - a script which seems to be useless. Do we really need it?

• System: 17.03pre98008.59dbcef (Gorilla)
• Nix version: nix-env (Nix) 1.11.4
• Nixpkgs version: "17.03pre98008.59dbcef"

I haven't heard of it before (which of course means nothing), but it is available on Ubuntu. Maybe we should investigate what it does. On the other hand: Does it hurt? Its 20K of size.

[matthiasbeyer]

Well.. depending on what it does it does hurt! :-) Either way, I would like to remove it if it is not needed.

The purpose is probably to correct the following effect: https://en.wikipedia.org/wiki/Keystone_effect
However if nobody can get it work, it can be removed.

It's a script for nickle (desk calculator language) but we haven't even packaged that. 👍 for removing the script.
