A very WIP mini compiler to help you mod Sapiens with Shaders

sapiens_shader_compiler.py

"""
This little utility allows you to quickly and easily create
shaders for Sapiens.

It functions by automatically pulling in required dependencies from the game
installation folder before compiling, allowing you to keep your project
clean.

Requires you to download compiler yourself.
