Is it possible to open a python script shell and execute a specific script? directly from other python application [packaged - and installed on the phone] using
if not:
Some time ago, I remember the script shell had some pre-startup config, where you could specify what *.py should be started at the time of startup, which I couldn't find it now. also would it work with script shell raised by another python app?

Also is it possible to register python apps to startup with phone?
