"""
Make Python wheel package (`*.whl`) file from Blender built with 'WITH_PYTHON_MODULE' enabled.
Example
=======
If the "bpy" module was build on Linux using the command:
make bpy lite
The command to package it as a wheel is:
./build_files/utils/make_bpy_wheel.py ../build_linux_bpy_lite/bin --output-dir=./
This will create a `*.whl` file in the current directory.
