	},
	warehouse => {
		db => {
			main => {
				name => 'cz',
				server => {
					host => 'localhost',
					port => 5432,
				},
				driver => 'Pg',
				role   => {
					admin => {
						login => 'cz_admin',

sub C { Crop::Config->data }

=begin nd
Method: I_can (%privileges)

sub I_can {

	my $server = $Crop::Server::Server;
	
	$server->rights->ok(%priv);
}

=begin nd
Method: S ()
	Accessor to the <Crop::Server>.
	
	Since an access to database by Server class is imposible if code is not running by FastCGI:
> $self->S->D

Returns:
	Server object - if is running
	'Crop' string - otherwise

TODO:
	The D() method.
