* Pantheios supports diagnostic logging of message statements of arbitrary complexity, consisting of heterogenous types. * Pantheios supports filtering of log messages based on severity level including (but not limited to) the eight levels defined by the SysLog protocol. * Pantheios supports back-end output, individually and in combination, to file, stderr/stdout, SysLog (including a custom implementation of the SysLog protocol for Windows), Windows debugger, Windows event log, COM Error Object, speech, or any custom back-end extension you care to write. Importantly, Pantheios is readily extended to use the existing transport mechanisms of feature-rich diagnostic logging libraries such as ACE, log4cpp, log4cplus, log4cxx.

* It is faster, safer and more powerful than log4c. * It can be widely used. * Open Source & Easy to use.
