+/** Test program for the syslog() system call.
+ *  From the syslog(2) man page:
+ *    If you need the libc function syslog()  (which  talks  to  syslogd(8)),
+ *    then look at syslog(3).  The system call of this name is about control‐
+ *    ling the kernel printk()  buffer,  and  the  glibc  version  is  called
+ *    klogctl().
