> @ottobackwards: Can we load files from disk? It would be nice to not have
had to setup kafka etc.
There is no requirement to setup Kafka. All you have to do is create a
String that contains your message. If you want to get that message from Kafka,
create it yourself using `SHELL_EDIT`, or copy-paste, then it works all the
same.
In this PR you cannot load from disk. ---
