Various parts of Quake 1 ported into Python. Some interesting modules:

• pyquake.proto: Parsing code for the quake network (and demo) protocol.
• pyquake.client: A programmatic asyncio Quake client.
• pyquake.blend{demo,mdl,bsp}: Load various quake structures into Blender. If you want to try this out see these instructions. Also see my blog post describing how this works.
• pyquake.pak: Mapping interface to the Quake filesystem.

Also the following entry points are provided:

• demo_viewer: View demo(s) in an OpenGL viewer.
• demo_parser: Parse demos into a human readable form.
• pyq_pak_extract: View and extract pak files.
