#
# ShaderToyProcessor.py
#
# This file is used to convert the shaders in a shadertoy entry to a Komplex wallpaper
# package. It is designed to automate the process of preparing and compiling the shader
# files.
#
# The process is as follows:
# 1) Process the Common.frag file, if it exists
# 2) Read in the source file (.frag)
# 3) Append the Common.frag file, if it exists
# 4) Save file as `Name.tmp` into the temp directory
# 5) Process `Name.tmp` with `cpp -P`, outputting it as `Name.frag`
# 6) Delete the temp file
# 7) Prepare `Name.frag` by adding ubuf struct and version info
# 8) Replace known buffer calls to their ubuf equivalent
# 9) Compile `Name.frag`
# 10) Copy non-shader files
#
# Usage:
# python ShaderToyProcessor.py [options] -i input_directory [-o output_dirctory] [-t temp_directory]
#
