SYNOPSIS
            use Mail::Karmasphere::Client qw(:all);

            my $client = new Mail::Karmasphere::Client(
                            PeerAddr        => '123.45.6.7',
                            PeerPort        => 8666,
                                    );

            my $query = new Mail::Karmasphere::Query();
            $query->identity('123.45.6.7', IDT_IP4_ADDRESS);
            $query->composite('karmasphere.emailchecker');
            my $response = $client->ask($query, 60);
            print $response->as_string;

            my $id = $client->send($query);
            my $response = $client->recv($query, 60);
            my $response = $client->recv($id, 60);

            my $response = $client->query(
                    Identities      => [ ... ]
                    Composite       => 'karmasphere.emailchecker',
                            );

DESCRIPTION
    The Perl Karma Client API consists of three objects: The Query, the
    Response and the Client. The user constructs a Query and passes it to a
    Client, which returns a Response.

CONSTRUCTOR
    The class method new(...) constructs a new Client object. All arguments
    are optional. The following parameters are recognised as arguments to
    new():

    PeerAddr
        The IP address or hostname to contact. See IO::Socket::INET. The
        default is 'slave.karmasphere.com'.

    PeerPort
        The TCP or UDP to contact. See IO::Socket::INET. The default is
        8666.

    Proto
        Either 'udp' or 'tcp'. The default is 'udp' because it is faster.

    Debug
        Either a true value for debugging to stderr, or a custom debug
        handler. The custom handler will be called with N arguments, the
        first of which is a string 'debug context'. The custom handler may
        choose to ignore messages from certain contexts.

METHODS
    $response = $client->ask($query, $timeout)
        Returns a Mail::Karmasphere::Response to a Mail::Karmasphere::Query.
        This is equivalent to

                $client->recv($client->send($query), $timeout)

    $id = $client->send($query)
        Sends a Mail::Karmasphere::Query to the server, and returns the id
        of the query, which may be passed to recv().

    $response = $client->recv($id, $timeout)
        Returns a Mail::Karmasphere::Response to the query with id $id,
        assuming that the query has already been sent using send(). If no
        matching response is read before the timeout, undef is returned.

    $response = $client->query(...)
        A convenience method, equivalent to

                $client->ask(new Mail::Karmasphere::Query(...));

        See Mail::Karmasphere::Query for more details.

EXPORTS
    IDT_IP4_ADDRESS IDT_IP6_ADDRESS IDT_DOMAIN_NAME IDT_EMAIL_ADDRESS
    IDT_URL
        Identity type constants.
