$ python test_raw_pylibcpupower.py
developing/using the bindings directly
--------------------------------------
You need to add the Python bindings directory to your $PYTHONPATH.
You would set the path in the Bash terminal or in the Bash profile:
PYTHONPATH=~/linux/tools/power/cpupower/bindings/python:$PYTHONPATH
This allows you to set a specific repo of the bindings to use.
installing/uninstalling
-----------------------
Python uses a system specific site-packages folder to look up modules to import
by default. You do not need to install cpupower to use the SWIG bindings.
You can install and uninstall the bindings to the site-packages with:
sudo make install
sudo make uninstall
