-"test/automated". From the "test/automated" directory, run "make
-<filename>" to run the tests for <filename>.el(c). See
-"test/automated/Makefile" for more information.

-Tests which are tagged ":expensive-test" are enabled additionally, if
-you run "make check-expensive" from the top-level directory. "make
-<filename>" as mentioned above incorporates expensive tests for
-<filename>.el(c). You can also define any ert selector on the command
-line. So "make check SELECTOR=nil" is equivalent to "make
-check-expensive".

-The best way to understand Emacs Internals is to read the code,
