+.PP
+.I Syslog
+creates the file
+/etc/syslog.pid
+if possible
+containing a single line
+with its process id.
+This can be used to kill or reconfigure
+.I syslog.
+.PP
+.I Syslog
+can also be compiled to use
+.IR mpx (2)
+files instead of datagrams
+if you are running V7.
+In this case it creates and reads the file
+/dev/log.
