Hello,

   So here is the question:
        "Is there any interest in a logging library for boost?"

   John Torjo did not answer my mail, beside I looked at pantheios. it 
seems a little bit complex... My idea is that a logging library should 
be _simple_ to use.

   Here is a small example:

// snippet on
#include <fstream>
#include <boost/logging.hpp>

int main(int argc, char **argv)
{
   BOOST_LOG_INIT(("[" >> boost::logging::level >> "],"
                       >> boost::logging::filename >> "("
                       >> boost::logging::line >> "),"
                       >> boost::logging::time >> ","
                       >> boost::logging::trace
                       >> boost::logging::eol), // log format
                       2);                      // log level

   BOOST_LOG_ADD_OUTPUT_STREAM(new std::ofstream("./output.log"));
   BOOST_LOG_ADD_OUTPUT_STREAM(&std::cout);

   BOOST_LOG(1, "something");
   BOOST_LOG(2, "something else");
   BOOST_LOG(3, "doesn't matter");
   char you_want[256] = "you want";
   BOOST_LOG(1, "Let's say " << you_want << " to display " << 2);

   return 0;
}
// snippet off

   You can find the first draft of a logging library in the boost 
Sandbox vault. It consists of a header files, some examples and 
documentation. Put the file at your boost root folder and unzip it.

   It compiles with msvc and vc-8_0. I'll try with gcc asap.

   So let me know if you think it worth something or not.
