     - A "prod" build includes the complete filesystem that's "frozen" into the build, so it's fast and all ready to go but the files in /lib and /builtin will be read-only.
     - A "dev" build comes without a filesystem, so it's perfect for power users that want to work on MicroPythonOS internals. There's a simple script that will copy all the necessary files over later, and these will be writeable.
-    Note: for unix and macOS systems, only "dev" has been tested. The "prod" builds might have issues.
