These Makefiles were beautiful, but now that the org_mode_samples are integrated into the rust test framework, it no longer makes sense to keep using these Makefiles. Instead, running scripts/run_integration_test.bash <org file under org_mode_samples>... will output the same information, additional information, and it will do it all without writing anything to disk (besides any files generated during compilation).
This line break appears in the output (for example a <br> in HTML) as opposed to the line breaks in paragraphs syntactically that get reduced to a single space on the same line.
