GxUtils:
By GameZelda, converts OBJ/MTL files to GMA/TPL files to be used by Super Monkey Ball.
main:
My utility, creates the LZ file from the OBJ file as well as a config file to tell the utility where to place various objects.

Usage:
Stated in GitHub, although you might want to look at the shell scripts to see what's going on in depth. Ignore the make command, as that was just to build the program. There needs to be a temp folder in the cd (current directory) as well. Running test.sh should make the program and run it correctly, provided you execute sh in the root directory of the project, and don't move anything.

[EDIT]First ever custom level!
