+ *  The library stores its primary #Logger as a static member of this class.
+ *  #get() returns this primary logger. By default the underlying implementation is
+ *  just a #NullLogger which rejects all log messages. By calling #create(), logging
+ *  is turned on. To capture the log output multiple log streams (#LogStream) can be
+ *  attach to the logger. Some default streams for common streaming locations (such as
+ *  a file, std::cout, OutputDebugString()) are also provided.
+ *
+ *  If you wish to customize the logging at an even deeper level supply your own
+ *  implementation of #Logger to #set().
+ *  @note The whole logging stuff causes a small extra overhead for all imports. */
