Hi, After more than a year of development my implementation of logging library is coming to its first release. Here are some feature highlights: * independent logger/sink and multimodule-friendly design with great extensibility potential * support for both embedded and global loggers * full-fledged attribute support (global, thread-specific and logger-specific attributes supported) * filtering and formatting support, including lambda expressions for filters and formatters construction * support for writing log to streams (files, console), rotating files support * support for Syslog API * support for library initialization helpers, including settings file support * thread safety support with least possible locking * wide-character logging support The library documentation can be found online on SourceForge: http://tinyurl.com/5e4fd7 Some requirements background can also be found on this Wiki: http://tinyurl.com/2fndfg The library code is quite stable, however, minor changes are still possible. The code can be checked out from the SourceForge CVS, the detailed instructions can be found here: http://tinyurl.com/6k9vvp There are currently no automatic tests, but there are some examples, which were compiled and run on Linux and Windows. I would like to see what Boost community thinks of this library, whether it worth submitting, has any critical flaws or any other thoughts. I also would appreciate if Gennadiy Rozental and John Torjo expressed their thoughts on possibility to review this library in parallel with John's solution, which is currently in the review queue. I would gladly discuss this privately, if they find it more suitable.
