= Building Blender as a Python Module =
== Overview ==
The official '''blender.org''' embeds a Python interpreter (CPython 3.x).
This makes sense from the perspective of a user, who's primary needs are to have an application which can be extended with scripts.
However from the perspective of a Python developer, it can be useful to being Blender into your existing scripts and access its feature set.
The option to build Blender as a Python module is not officially supported, ''in the sense Blender.org isn't distributing it along with regular releases'',
