nova.sh - a simple script to handle the build lifecycle of the Nova renderer

Allows you to set up Nova on a new machine, compile Nova, and run Nova (hopefully), all from a single script with a simple interface

Available parameters:

setup - downloads MCP and uses it to decompile Minecraft, downloads Nova's dependencies, and applies the source code patches to Minecraft

build - compiles the C++ code, moves the shared library to the proper directory, and compiles the Java code

nativeOnly - only compiles the C++ code and moves the shared library to the proper directory. Does not compile the Java code. This option is only considered if 'build' is also specified. 'build' must be the first argument, then this one

clean - deletes all compiled code and generated build files

run - runs Nova
