Pantheios is a C++ logging API library that provides type-safe log calls listing arguments instead of format strings, and is designed so that it costs almost nothing when a log level is turned off. It separates the front end (severity decision) from the back end (output target), so output can be swapped among the console, files, syslog, the Windows event log, and so on; it depends on STLSoft. Its emphasis on performance is what sets it apart from the log4j family such as log4cxx.
