Importer

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
