+## Some targets:
+## check: re-run all tests, writing to .log files.
+## check-maybe: run all tests whose .log file needs updating
+## filename.log: run tests from filename.el if .log file needs updating
+## filename: re-run tests from filename.el, with no logging
+
+## Adapted from test/automated/Makefile.in of GNU Emacs.
