Snowfall Lib automatically exports your packages on your flake and makes them available to
all other parts of your flake. This includes making these packages available to other packages
in your flake, NixOS systems, Darwin systems, Home Manager, modules, and overlays.
To create a new package, add a new directory your packages directory.
Now create the Nix file for the package at packages/my-package/default.nix.
This package will be made available on your flakeās packages output with the same name as the
directory that you created.
