How to make a orig.zip and mod.zip file?

[R1310328554]

Hi, hacker:

What the README wrote is :
python hp_solution_patcher.py orig.bdl orig.zip mod.zip

Now , I have a xxx.bdl, However, how can make a orig.zip and mod.zip file from BDL? Especially the orig.zip. Can I just unzip the BDL to create a orig.zip?
