+nmh test suite
+--------------
+
+The nmh test suite is run through the Makefile, with "make check"
+or "make distcheck".
+
+To enable the use of valgrind, where available, set the environment
+variable NMH_VALGRIND to a non-null value.  However, a separate
+environment variable, VALGRIND_ME, triggers the use of valgrind in
+test/inc/test-eom-align because it greatly extends the duration of
+that test.
+
+In the nmh test suite, nmh programs to be tested should be invoked
+through the run_test or run_prog shell functions defined in
+test/common.sh.
