/**
 * Logs messages to configured Log adapters. One or more adapters
 * can be configured using CakeLogs's methods. If you don't
 * configure any adapters, and write to the logs a default
 * FileLog will be autoconfigured for you.
 *
 * ### Configuring Log adapters
 *
 * You can configure log adapters in your applications `bootstrap.php` file.
 * A sample configuration would look like:
 *
 * ```
 * CakeLog::config('my_log', array('engine' => 'File'));
 * ```
 *
 * See the documentation on CakeLog::config() for more detail.
 *
 * ### Writing to the log
 *
 * You write to the logs using CakeLog::write(). See its documentation for more
 * information.
 *
 * ### Logging Levels
 *
 * By default CakeLog supports all the log levels defined in
 * RFC 5424. When logging messages you can either use the named methods,
 * or the correct constants with `write()`:
 *
 * ```
 * CakeLog::error('Something horrible happened');
 * CakeLog::write(LOG_ERR, 'Something horrible happened');
 * ```
 *
 * If you require custom logging levels, you can use CakeLog::levels() to
 * append additional logging levels.
 *
 * ### Logging scopes
 *
 * When logging messages and configuring log adapters, you can specify
 * 'scopes' that the logger will handle. You can think of scopes as subsystems
 * in your application that may require different logging setups. For
 * example in an e-commerce application you may want to handle logged errors
 * in the cart and ordering subsystems differently than the rest of the
 * application. By using scopes you can control logging for each part
 * of your application and still keep standard log levels.
 *
 * See CakeLog::config() and CakeLog::write() for more information
 * on scopes
 *
 * @package       Cake.Log
 * @link http://book.cakephp.org/2.0/en/core-libraries/logging.html#logging

/**
 * Configure and add a new logging stream to CakeLog
 * You can use add loggers from app/Log/Engine use app.loggername, or any
 * plugin/Log/Engine using plugin.loggername.
 *
 * ### Usage:
 *
 * ```
 * CakeLog::config('second_file', array(
 *     'engine' => 'File',
 *     'path' => '/var/logs/my_app/'
 * ));
 * ```
 *
 * Will configure a FileLog instance to use the specified path.
 * All options that are not `engine` are passed onto the logging adapter,
 * and handled there. Any class can be configured as a logging
 * adapter as long as it implements the methods in CakeLogInterface.
 *
 * ### Logging levels
 *
 * When configuring loggers, you can set which levels a logger will handle.
 * This allows you to disable debug messages in production for example:
 *
 * ```
 * CakeLog::config('default', array(
 *     'engine' => 'File',
 *     'path' => LOGS,
 *     'levels' => array('error', 'critical', 'alert', 'emergency')
 * ));
 * ```
 *
 * The above logger would only log error messages or higher. Any
 * other log messages would be discarded.
 *
 * ### Logging scopes
 *
 * When configuring loggers you can define the active scopes the logger
 * is for. If defined only the listed scopes will be handled by the
 * logger. If you don't define any scopes an adapter will catch
 * all scopes that match the handled levels.
 *
 * ```
 * CakeLog::config('payments', array(
 *     'engine' => 'File',
 *     'types' => array('info', 'error', 'warning'),
 *     'scopes' => array('payment', 'order')
 * ));
 * ```
 *
 * The above logger will only capture log entries made in the
 * `payment` and `order` scopes. All other scopes including the
 * undefined scope will be ignored. Its important to remember that
 * when using scopes you must also define the `types` of log messages
 * that a logger will handle. Failing to do so will result in the logger
 * catching all log messages even if the scope is incorrect.
 *
 * @param string $key The keyname for this logger, used to remove the
 *    logger later.
 * @param array $config Array of configuration information for the logger
 * @return bool success of configuration.
