LÖVE

Hey guys. I just got interested in love, and am messing around with it.

I'm just curious what the dbg package is for? I have liblove and love packages installed, and started downloading dbg, but not sure if I really need it or not.

Thanks in advance

I'm assuming you're using ubuntu/debian. The dbg package hold "debug symbols", which will make your game easier to debug if the engine crashes. Normal errors caused by your game shouldn't need this, so most of the time the dbg package isn't necessary.
