Pantheios - The C/C++ Logging Sweetspot

A C++ diagnostic logging API that is simple to use, 100% type-safe, generic, infinitely-extensible, atomic, platform-independent, and extremely efficient. And, best of all, it upholds the spirit of C: you only pay for what you use. Pantheios is readily extended to use the existing transport mechanisms of feature-rich diagnostic logging libraries such as ACE, log4cpp, log4cplus, log4cxx.
