App::PersistentSSH - Kick an F<ssh> control master around on OSX using
F<scutil>

=head1 SYNOPSIS

	% persisshtent --host your.host.com

=head1 DESCRIPTION

This POE component will keep an SSH control master alive, depending on network status.

It uses the OSX command line tool F<scutil> to get notification on changes to
the C<State:/Network/Global/IPv4> configuration key. Whenever this key is changed
C<scutil -r> will be used to check if the specified host is directly reachable
(without creating a connection using e.g. PPP), and if so spawn F<ssh>.

If the host is not reachable, F<ssh> is stopped.
