If the user sets the environment variable M5_OVERRIDE_PY_SOURCE to True, then imports that would normally find python code compiled into the executable will instead first check in the absolute location where the code was found during the build of the executable. This only works for files in the src (or extras) directories, not automatically generated files. This is a developer feature!
