The "AtariSIO tools" are a set of command line tools to handle "ATR" and "COM/XEX" files. Mathias Reichel created them, and they are available on his website http://www.horus.com/~hias/atari. Since I am now familiar with Git and Git Hub and own an Intel & Apple Silicon macOS machine and a Linux VM, I've created binary builds and uploaded them to the WUDSN Tools Git Hub repo for your convenience.
