# Main test script (comments out-of-line because macOS otherwise barfs?!?)
# - Determine reference file (`REF`).
# - Print user-visible status line.
# - Dump Coq output into a temporary file.
# - Run `sed -i` on that file in a way that works on macOS.
# - Either compare the result with the reference file, or move it over the reference file.
# - Cleanup, and mark as done for make.
