This directory should be populated with the actual python script that you want to run
This directly should be populated with symlinks to the share/wrapper script, one for each executable in libexec
This has additional utilities to make things work as expected. Primarily this directory has the wrapper script used to populate the PYTHONPATH variable so that it includes the lib/ directory relative to the asset.
This is where you will install needed python modules using pip install --target <path>
The python runtime asset includes a pip that can be used during the build process.
So best practise is to build python assets using the python runtime asset version you want to work with.
Look at the example/ for an example of the python-asset following this structure.
