# converts slang source file into a C header containing one big string
# comments and trailing whitespaces are stripped
# C style comments are not supported, only C++ style ones are
# empty lines are kept to maintain line numbers correlation
# escape characters are not handled except for newlines

# example:
# -- source file
# // some comment
# 
# attribute vec4 myPosition;	// my vertex data
# -- output file
# "\n"
# "\n"
# "attribute vec4 myPosition;\n"

# usage: gc_to_string.py filename.gc > filename_gc.h
