+
+"""socket interface to unix syslog.
+On Unix, there are usually two ways of getting to syslog: via a
+local unix-domain socket, or via the TCP service.
+
+Usually "/dev/log" is the unix domain socket.  This may be different
+for other systems.
+
+>>> my_client = syslog_client ('/dev/log')
+
+Otherwise, just use the UDP version, port 514.
+
+>>> my_client = syslog_client (('my_log_host', 514))
+
+On win32, you will have to use the UDP version.  Note that
+you can use this to log to other hosts (and indeed, multiple
+hosts).
+
+This module is not a drop-in replacement for the python
+<syslog> extension module - the interface is different.
+
+Usage:
+
+>>> c = syslog_client()
+>>> c = syslog_client ('/strange/non_standard_log_location')
+>>> c = syslog_client (('other_host.com', 514))
+>>> c.log ('testing', facility='local0', priority='debug')

+
+"""socket interface to unix syslog.
+On Unix, there are usually two ways of getting to syslog: via a
+local unix-domain socket, or via the TCP service.
+
+Usually "/dev/log" is the unix domain socket.  This may be different
+for other systems.
+
+>>> my_client = syslog_client ('/dev/log')
+
+Otherwise, just use the UDP version, port 514.
+
+>>> my_client = syslog_client (('my_log_host', 514))
+
+On win32, you will have to use the UDP version.  Note that
+you can use this to log to other hosts (and indeed, multiple
+hosts).
+
+This module is not a drop-in replacement for the python
+<syslog> extension module - the interface is different.
+
+Usage:
+
+>>> c = syslog_client()
+>>> c = syslog_client ('/strange/non_standard_log_location')
+>>> c = syslog_client (('other_host.com', 514))
+>>> c.log ('testing', facility='local0', priority='debug')
