+
+Runs PROGRAM under the control of CHECKER.
+
+CHECKER may be empty or a valgrind command with some options, such as
+'valgrind --tool=memcheck --num-callers=20 --leak-check=yes --leak-resolution=high --show-reachable=yes'.
+
+When CHECKER is not empty, it is recommended that the package has been
+configured with
+  --disable-shared     so that tests are real executables and not libtool
+                       wrapper scripts, and
+  CFLAGS=\"-g\"          so that valgrind shows line numbers.
