URL: http://svn.boost.org/trac/boost/changeset/43712
Log:
v0.23.2, 18 march 2008
- destination::rolling_file - by default, flush after each write
- destination::file - file is created only if logging to it
(this way, if using named_writer, you won't see spurious files called out.txt, even if not using them)
- destination::rolling_file - file is created only if logging to it

+@section last_v2 Last version of v2.
+
+The Boost Logging Lib v2 was rejected on 17th of March 2008. I will be working on v3.
+So, you can consider v0.23.2 as the last version of v2. From now on,
+- I will be doing only small fixes, if any major bugs, I'll fix them
+- I will be working on v3. It might take a while until first version of v3 appears - I assume End of April
+- to stay tuned on development, and to make sure your oppinion counts, please check out http://torjo.blogspot.com

+@example mul_levels_mul_logers.cpp
+
+@copydoc mul_levels_mul_logers
+
+@page mul_levels_mul_logers mul_levels_mul_logers.cpp Example
+
+
+This usage:
+- you have multiple levels (in this example: debug < info < error)
+- you want to format the message before it's written
+ (in this example: prefix it by time, by index and append newline to it)
+- you have several loggers
+- each logger has several log destinations
+
+Optimizations:
+- use a cache string (from boost::logging::optimize namespace), in order to make formatting the message faster
+
+Logs:
+- error messages go into err.txt file
+ - formatting - prefix each message by time, index, and append newline
+- info output goes to console, and a file called out.txt
+ - formatting - prefix each message by "[app]", time, and append newline
+- debug messages go to the debug output window, and a file called out.txt
+ - formatting - prefix each message by "[dbg]", time, and append newline
+
+
+Here's how the output will look like:
+
+The debug output window:
+@code
+07:52.30 [dbg] this is so cool 1
+07:52.30 [dbg] this is so cool again 2
+@endcode
+
+
+The console:
+@code
+07:52.30 [app] hello, world
+07:52.30 [app] good to be back ;) 4
+@endcode
+
+
+The out.txt file:
+@code
+07:52.30 [dbg] this is so cool 1
+07:52.30 [dbg] this is so cool again 2
+07:52.30 [app] hello, world
+07:52.30 [app] good to be back ;) 4
+@endcode
+
+
+The err.txt file
+@code
+07:52.30 [1] first error 3
+07:52.30 [2] second error 5
+@endcode
