+	@short	Log.
+
+	The log subsystem provides several log levels to enable activation and
+	deactivation of a whole log level.
+
+	The following log streams are available to log to the different levels:
+
+	* __LOG_H__: Header			(eg: __LOG_H__ << "Physics entry point.\n")
+	* __LOG_W__: Warning
+	* __LOG_E__: Error
+	* __LOG_E__: Non-maskable
+
+	Standard logs may be output to the __LOG__ stream.
