+/**
+@example ded_loger_one_filter.cpp
+
+@copydoc ded_loger_one_filter
+
+@page ded_loger_one_filter ded_loger_one_filter.cpp Example
+
+
+This usage:
+- You have one @b thread-safe logger - the logging is done @ref boost::logging::writer::on_dedicated_thread "on a dedicated thread"
+- You have one filter, which is always turned on
+- You want to format the message before it's written
+- The logger has several log destinations
+ - The output goes debug output window, and a file called out.txt
+ - Formatting - prefix each message by time, its index, and append enter
+
+Optimizations:
+- use a cache string (from optimize namespace), in order to make formatting the message faster
+
+In this example, all output will be written to the console, debug window, and "out.txt" file.
+It will look similar to:
+
+@code
+...
+30:33 [10] message 1
+30:33 [11] message 2
