Trying to learn intermediate Doom 2 editing.
Where do I declare these "using" statements from the DECOHack documentation?
I've never used DeHackEd or DECORATE before.
./src/main.dh seems to be where the DECOHack code goes, but it doesn't seem like a "using" statement should go here (there's already C-esque #include declarations, plus adding a "using" throws an error.)
