AnyEvent::Atom::Stream - XML::Atom::Stream with AnyEvent

=head1 SYNOPSIS

  use AnyEvent::Atom::Stream;

  my $url = "http://updates.sixapart.com/atom-stream.xml";
  my $cv  = AnyEvent->condvar;

  # API is compatible to XML::Atom::Stream
  my $client = AnyEvent::Atom::Stream->new(
      callback  => \&callback,
      timeout   => 30,
      on_disconnect => $cv,
  );
  my $guard = $client->connect($url);

  $cv->recv;

  }

any of AnyEvent event loop implementation.

=over 4

=item new

  $client = AnyEvent::Atom::Stream->new(
      callback => \&callback,
      timeout  => 30,
      on_disconnect => $cv,
  );

Creates a new AnyEvent::Atom::Stream instance. The API is compatible
to XML::Atom::Stream, but it doesn't support C<reconnect> parameter,
because that's something you can easily control with the new
I<on_disconnect> AnyEvent callback.

=item connect

  $guard = $client->connect($url);

Connects and receives Atom update stream.
