$! notes :
$! 1) attempt to invoke a python script so it is compiled once, then cached
$! 2) for this to work properly, the file format must be stream_lf
$! a) this is the default format if initially created with the vi editor
$! b) must be converted to stream_lf (via $convert/create) if first
$! created via either the $EDT or $EVE editors
$! 3) while all three methods work, method 2 appears to be the best because
$! method 3 is unable to determine the python program name via:
$! script = sys.argv[0]
$! 4) CAVEAT: if the python file is not in the stream_lf format, then choices
$! 2+3 will always create a new pyc file which will eventually overflow
$! folder [.__pycache__]
