=head1 NAME
Mojo::Log::Syslog - syslog for Mojo projects
=head1 SYNOPSIS
use Mojo::Log::Syslog;
$logger = new Mojo::Log::Syslog(facility => 'user',
ident => 'myapp',
level => 'warn');
app->log($logger);
=head1 DESCRIPTION
Syslog-based logger for Mojo applications.
=head1 CONSTRUCTOR
The B<Mojo::Log::Syslog> constructor takes the following keyword arguments,
all of which are optional:
=over 4
=item B<facility =E<gt>> I<FACILITY>
Sets the syslog facility to use. Valid facility names are: C<auth>,
C<authpriv>, C<cron>, C<daemon>, C<ftp>, C<kern>, C<local0> through
C<local7>, C<lpr>, C<mail>, C<news>, C<user>, and C<uucp>. See also
B<Sys::Syslog>(3), section B<Facilities>.
The default is C<user>.
=item B<ident =E<gt>> I<STRING>
Syslog message identifier. Defaults to the base name from B<$0>.
=item B<logopt =E<gt>> I<OPTLIST>
Defines the list of options for B<openlog>. I<OPTLIST> is either a string
with comma-separated option names or a list reference containing option
names. The following two options are equivalent:
logopt => "ndelay,pid,nowait"
logopt => [qw(ndeay pid nowait)]
See B<Sys::Syslog>(3) for a list of available option names.
Defaults to C<ndelay,pid>.
=item B<level E<gt>> I<NAME>
Sets minimum logging level. See B<Mojo::Log>, for a list of levels.
=back
=head1 METHODS
All methods are inherited from B<Mojo::Log>. The methods B<debug>, B<warn>,
B<info>, and B<error> log their messages using the corresponding B<syslog>
priorities. The method B<fatal> uses the C<crit> (B<LOG_CRIT>) priority.

level => 'warn');
app->log($logger);
=head2 Using with Mojolicious
package MyApp;
use Mojo::Base 'Mojolicious';
sub startup {
my $self = shift;
my $logger = new Mojo::Log::Syslog(facility => 'local0',
