This is a collection of nix-shell recipes organized under a top-level default.nix expression. It's structured so recipes can be referenced by attribute name:

nix-shell --attr use-db \
    https://github.com/ivanbrennan/nixels/archive/master.tar.gz

Recipes are versioned and git tags of the form <recipe>-<version> are provided, allowing you to reference a particular version:

nix-shell --attr use-db \
    https://github.com/ivanbrennan/nixels/archive/use-db-0.1.0.tar.gz

I've also written a CLI, shellbit, to make referencing recipe collections like this one less cumbersome:

$ cd /path/to/projects/use-db
$ shellbit
[nix-shell:~/Development/use-db]$
