Hello, this script will download and compile Cuberite.

On subsequent runs, it will update Cuberite.

The compilation and download will occur in the current directory.

If you're updating, you should run: <Path to Cuberite>/compile.sh

Compiling from source takes time, but it usually generates faster

executables. If you prefer ready-to-use binaries or if you want
