quol

Project: Zezax/One/Quol

The name of this project directory is quol, because it needed a name. There is an obscure animal called the quoll, but I wanted a four-letter name becasuse I'm lazy. It sounds like the beginning of "quality".

The largest sub-project is RED, the DFA regex engine. Much of the rest is biased toward Debian using systemd. There is a fair amount of RRD.
