Initially, this repo was just a simple C version of Hello World.
I have used it to build native and cross-compile on various targets such as RPi3b and PocketBeagle.
I created ./rpi_docker with the help of jules.google.com some time ago.
It provides an emulated Raspberry Pi using a Docker container.
There is a ./doit bash script that provides a quick start and documents the commands to use the Docker container.
Updated repo back to public, stashing some "Jules.google.com" work.
