Dorothy — https://github.com/bevry/dorothy — is a dotfile ecosystem comprised of three parts:
1. Commands that streamline everyday interactions with your machine, such keeping your system and its packages updated, securely managing environment secrets, correctly configuring secure DNS, as well as for managing ecosystems like homebrew, snap, flatpak, node, python, ruby, go, rust, etc.
2. Commands that streamline the authorship of your own dotfile commands, such as processing inputs and outputs, handling colours and quite mode, managing configurations.
3. An initialisation script that will ensure your environment is correctly configured and adapted to your machine and its installed utilities, supporting Bash, Zsh, Fish, and Nushell.

All this with cross-shell, cross-os, and cross-architecture portability, enabling interchangeability between such.
