+  # Initializes default options for the logger
+  # <tt>ident</tt>:: the name of your program [default=$0].
+  # <tt>options</tt>::  syslog options [default=<tt>Syslog::LOG_PID | Syslog::LOG_CONS</tt>].
+  #                     Correct values are:
+  #                       LOG_CONS    : writes the message on the console if an error occurs when sending the message;
+  #                       LOG_NDELAY  : no delay before sending the message;
+  #                       LOG_PERROR  : messages will also be written on STDERR;
+  #                       LOG_PID     : adds the process number to the message (just after the program name)
+  # <tt>facility</tt>:: the syslog facility [default=nil] Correct values include:
