+/* gethostn - a small diagnostic utility to show what the
+ * gethostname() API returns. Of course, this tool duplicates
+ * functionality already found in other tools. But the point is
+ * that the API shall be called by a program that is compiled like
+ * rsyslogd and does exactly what rsyslog does.
