Also add 'lsd'. This project is a rewrite of GNU ls with lot of added features like colors, icons, tree-view, more formatting options etc. The project is heavily inspired by the super colorls project.

Also add 'fd'. fd is a program to find entries in your filesystem. It is a simple, fast and user-friendly alternative to find. While it does not aim to support all of find's powerful functionality, it provides sensible (opinionated) defaults for a majority of use cases.
