	, init: function( options ){
		this.parent.init( options );
		this.tableName = options.tableName;
	}


	, describe: function( callback ){
		this.request( "DescribeTable", { TableName: this.tableName }, function( err, status, data ){
			if ( err ) callback( err );
			else if ( status !== 200 ) callback( new Error( "request failed because ..." ) );
			else {
				callback( null, data );
			}
		}.bind( this ) );
	}
} );



var usertable = new DynamoDBTable( {
	  key: 			"AKI..."
	, secret: 		"W5FF..."
	, service: 		"DynamoDB"
	, region: 		"eu-west-1"
	, version: 		"20120810"
