The README:

> Nothing is wrong with udev. In fact udev is great, as should be obvious from its 20+ years of service on nearly every GNU/Linux system out there. The rule format it pioneered has stood the test of time and can almost be considered a "standard". > > However, udev is not easily usable on systems without systemd and Linux. This project, like eudev and others, aims to address that. Unlike eudev however, this is a completely independent implementation instead of a "fork".
