 This is Plover, a configuration meant to be used in a low-powered general-purpose machine.
 It isn't much of an instance to be seriously used yet but hopefully it is getting there.

 These are various modules ranging from link:https://nixos.org/manual/nixos/stable/index.html#sec-writing-modules[NixOS modules] and link:https://github.com/nix-community/home-manager[home-manager] modules.
 
-The modules are imported usually through `lib.filesToAttr`, allowing for easier structuring without modifying the index file of each module (i.e., `default.nix`).
-(See the implementation for more details.)
