P24HLS

Currently only converts to HL2 instead of HLS. It might work for HLS, idk

If you want textures (which i imagine you do), VTF.py and MDL.py are your friends.
Give them the path to the directory you extracted from the .vpk's and they will patch the textures.

If you want COMPLETE texture and cubemap parity, you need to know how to extract and recompress pakfiles.
Do your own research for this.

Do "main.py -h" for information on the main program.
