# Script only looks at not referenced files from three directories: include, library and profiler
# CK needs to be built with ability to use dependency parser and generate dependencies

# Usage: python3 generate_list_of_files_not_referenced_in_tests -f /path/to/enhanced_dependency_mapping/json/file
