"""
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.

# Long Description
long_description = """# Blender
[Blender](https://www.blender.org) is the free and open source 3D creation suite. It supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing.
This package provides Blender as a Python module for use in studio pipelines, web services, scientific research, and more.
## Documentation
* [Blender Python API](https://docs.blender.org/api/current/)
* [Blender as a Python Module](https://docs.blender.org/api/current/info_advanced_blender_as_bpy.html)
## Requirements
[System requirements](https://www.blender.org/download/requirements/) are the same as Blender.
Each Blender release supports one Python version, and the package is only compatible with that version.
## Source Code
* [Releases](https://download.blender.org/source/)
* Repository: [projects.blender.org/blender/blender.git](https://projects.blender.org/blender/blender)
## Credits
Created by the [Blender developer community](https://www.blender.org/about/credits/).
Thanks to Tyler Alden Gubala for maintaining the original version of this package."""
