+/**
+ * @file
+ * Contains \Drush\Log\Logger.
+ *
+ * This is the actual Logger for Drush that is responsible
+ * for logging messages.
+ *
+ * This logger is designed such that it can be provided to
+ * other libraries that log to a Psr\Log\LoggerInterface.
+ * As such, it takes responsibility for passing log messages
+ * to backend invoke, as necessary (c.f. drush_backend_packet()).
+ *
+ * Drush supports all of the required log levels from Psr\Log\LogLevel,
+ * and also defines its own. See Drush\Log\LogLevel.
+ *
+ * Those who may wish to change the way logging works in Drush
+ * should therefore NOT attempt to replace this logger with their
+ * own LoggerInterface, as it will not work. It would be okay
+ * to extend Drush\Log\Logger, or perhaps we could provide a way
+ * to set an output I/O object here, in case output redirection
+ * was the only thing that needed to be swapped out.
