+You can choose an emacs binary (and corresponding emacsclient) to run
+the tests in one of the following ways.
+
+ TEST_EMACS=my-special-emacs TEST_EMACSCLIENT=my-emacsclient make test
+ TEST_EMACS=my-special-emacs TEST_EMACSCLIENT=my-emacsclient ./emacs
+ make test TEST_EMACS=my-special-emacs TEST_EMACSCLIENT=my-emacsclient
+
+Some tests may require a c compiler. You can choose the name and flags similarly
+to with emacs, e.g.
+
+ make test TEST_CC=gcc TEST_CFLAGS="-g -O2"
+
+Quiet Execution
+---------------
+
+Normally, when new script starts and when test PASSes you get a message
+printed on screen. This printing can be disabled by setting the
+NOTMUCH_TEST_QUIET variable to a non-null value. Message on test
+failures and skips are still printed.
