=head1 NAME

Net::Syslog - Perl extension for sending syslog messages directly to a remote syslogd.

=head1 SYNOPSIS

  use Net::Syslog;
  my $s=new Net::Syslog(Facility=>'local4',Priority=>'debug');
  $s->send('see this in syslog',Priority=>'info');

=head1 DESCRIPTION

Net::Syslog implements the intra-host syslog forwarding protocol.
It is not intended to replace the Sys::Syslog or
Unix::Syslog modules, but instead to provide a method of using syslog when a
local syslogd is unavailable or when you don't want to write syslog messages
to the local syslog.

The new call sets up default values, any of which can be overridden in the
send call.  Keys (listed with default values) are:

	Name		<calling script name>
	Facility 	local5
	Priority 	err
	SyslogPort    	514
	SyslogHost    	127.0.0.1

Valid Facilities are:
	kern, user, mail, daemon, auth, syslog, lpr, news, uucp, cron, 
	authpriv, ftp, local0, local1, local2, local3, local4, local5, local6

Valid Priorities are:
	emerg, alert, crit, err, warning, notice, info, debug
