Please see file COPYING for details.

Please note that the xmlwitch module included in the importer is BSD licensed (please see file for details).

The only existing component currently is the importer facility, which is a Python program that reads game geometry from the "Split Disassembly" provided by the good folks at Sonic Retro. This can be acquired with: svn co https://sonicretro.org/asm_svn

To produce collision geometry SVG from Sonic 2, run from the root of the HedgehogHD repo:

hedgehoghd/importer/hedgehoghd_import.py ~/path/to/asm_svn ~/svg_output/

To produce HTML documentation:

cd doc
make html
