"""Execute a Python script using :py:func:`execfile`.
In addition to Python :py:func:`execfile` this method can temporary change the argv params.
This enables you to call an external python script that requires
command line arguments without leaving current python interpretor.
`cmd` can be a string with command line arguments or a list or arguments
The return value is a numeric exit code similar to the one used for command line tools:
- 0 - if succesfull; this applies if script receives SystemExit with error code 0
- 1 - if SystemExit does not contain an error code or if other Exception is received.
- x - the SystemExit error code (if present)
