=head2 config

A hash pointer to the configuration object. See L for details.
The default configuration file is located in etc/callbackery.cfg. You can override the
path by setting the C environment variable.

The config property is set automatically on startup.

=cut

has 'config' => sub {
    my $app = shift;
    my $conf = CallBackery::Config->new(
        app => $app,
        file => $ENV{CALLBACKERY_CONF} || $app->home->child('etc','callbackery.cfg')
    );
};

=head2 database

An instance of L or a module with the same API.

=cut

has database => sub {
    CallBackery::Database->new(app=>shift);
};

has userObject => sub {
    my $app = shift;
    my $ obj = CallBackery::User->new(app=>$app,log=>$app->log);
    $obj->{prototype} = 1;
    return $obj;
};

=head2 securityHeaders

A hash of headers to set on every response to ask the webbrowser to
help us fight the bad guys.

=cut

has securityHeaders => sub { {
    # prevent click jacking
    'X-Frame-Options' => 'SAMEORIGIN',
    # some magic browser based anti xss action
    'X-XSS-Protection' => '1; mode=block',
    # the browser should obej the servers settings regarding content-type
    'X-Content-Type-Options' => 'nosniff',
    # do not store our data ever
    'Pragma' => 'private',
}};

=head2 rpcServiceNamespace

our rpc service namespace

=cut

has rpcServiceNamespace => 'CallBackery';

=head2 rpcServiceController

our rpc service controller

=cut

has rpcServiceController => 'Controller::RpcService';

=head2 docIndex

initial document to be presented on the doc link

=cut

has docIndex => __PACKAGE__ . '::Index';

=head1 METHODS

All  the methods of L as well as:

=head2 startup
