  20 ### Commentary:
  21
  22 ## Some targets:
  23 ## check: re-run all tests, writing to .log files.
  24 ## check-maybe: run all tests which are outdated with their .log file
  25 ## or the source files they are testing.
  26 ## filename.log: run tests from filename.el(c) if .log file needs updating
  27 ## filename: re-run tests from filename.el(c), with no logging
