Command for templating message for MQTT to use in i3blocks.
Development Status: Currently, I am only using this myself.
This project is open source, but not open for contribution, since helping contributors to ship a PR usually takes more time than doing it myself. Please drop an issue, if you want something changed. Also of course it is possible to fork the whole project.
