 Logging in **CUBOS.** is done through the logging macros defined in @ref core/log.hpp.
 
-@dontinclude logging.cpp
-@snippet logging.cpp Logging include
+@snippet logging/main.cpp Logging include
 
 Before any logging is done, the logger must be initialized.
 This usually happens right at the beginning of the program.

 There are six logging levels, each with its own macro.
 In order of increasing severity, they are:
 
-@snippet logging.cpp Logging macros
+@snippet logging/main.cpp Logging macros
 
 These macros can also take arguments:
 
-@snippet logging.cpp Logging macros with arguments
+@snippet logging/main.cpp Logging macros with arguments
 
 @note By default, on debug builds all messages are logged, while on release builds only messages with
 severity level @ref CUBOS_LOG_LEVEL_INFO or higher are logged. This can be changed by defining
 @ref CUBOS_LOG_LEVEL to the desired level.
 
 Serializable types can also be logged, using @ref cubos::core::data::Debug.
 
-@snippet logging.cpp Debug wrapper include
+@snippet logging/main.cpp Debug wrapper include
 
 By wrapping the value in @ref cubos::core::data::Debug, the type is serialized using the
 @ref cubos::core::data::DebugSerializer, and the result is logged.
