+nmh temporary files
+-------------------
+
+To create a temporary file, use m_mktemp2() or m_mktemp().  They use
+mkstemp(3), but they also register the temporary file for removal on
+program termination.  So, do not use mkstemp() directly.
+
+To further support this, nmh_init() must be called at the beginning of
+main().  And, if a child process is not going to immediately call one
+of the exec(3) functions or _exit(3) after a fork(3), it should call
+unregister_for_removal(0).  Finally, nmh_init() sets up signal handlers
+for several signals:  these signal handlers should not be disabled.

+
+--------------
+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.
