# First build a string that has a preprocessor include

# sbSrc contains:
# 	1
# 	2
# 	3
# 	#include <qa_data/txt/helloWorld.txt>
# 	4
# 	5

# The qa_data/txt/helloWorld.txt file contains "Hello World!"

# Replace the first occurrence of #include <...> line with the contents of the include file.

# sbSrce now contains:
