The nixpkgs-unstable channel's programs.sqlite was used to identify
packages producing exactly one binary, and these automatically added
to their package definitions wherever possible.
Update, also change from
pname = "package-unstable";
version = "YYYY-MM-DD";
to
pname = "package";
version = "unstable-YYYY-MM-DD";
This allows $pname as $repo in fetchFromGitHub and also seems to be the
more common way in nixpkgs.
