Extracts SPL Python primitive operators from decorated Python classes and functions.
Executing this script against an SPL toolkit creates the SPL primitive operator meta-data required by the SPL compiler (sc).

SPL Python primitive operators¶
SPL operators that call a Python function or callable class are created by decorators provided by the streamsx package.
To create SPL operators from Python functions or classes one or more Python
modules are created in the
of an SPL toolkit.
spl-python-extract is a Python script that creates SPL operators from
Python functions and classes contained in modules under
The resulting operators embed the Python runtime to allow stream processing using Python.
