Net::DBus::Service - Provide a service to the bus for clients to use

=head1 SYNOPSIS

package main;

use Net::DBus;

# Attach to the bus
  my $bus = Net::DBus->find;

# Acquire a service 'org.demo.Hello'
  my $service = $bus->export_service("org.demo.Hello");

# Export our object within the service
  my $object = Demo::HelloWorld->new($service);

....rest of program...

=head1 DESCRIPTION

This module represents a service which is exported to the message
bus. Once a service has been exported, it is possible to create
and export objects to the bus.

package Net::DBus::Service;

use 5.006;
use strict;
use warnings;

=item my $service = Net::DBus::Service->new($bus, $name);

Create a new service, attaching to the bus provided in
the C<$bus> parameter, which should be an instance of
the L<Net::DBus> object. The C<$name> parameter is the
qualified service name. It is not usually necessary to
use this constructor, since services can be created via
the C<export_service> method on the L<Net::DBus> object.

When C<$name> is not specified or is C<undef> then returned
handle to the service is identified only by the unique name
of client's connection to the bus.

Retrieves the L<Net::DBus> object to which this service is
attached.

Retrieves the qualified name by which this service is
known on the bus.
