-/**
- @brief It's a filter that enables holding a level
-
- Allows managing whether a level is enabled or not (so that a logggers that wants to use levels,
- can determine if it's enabled or not)
-
- Example:
-
-_at_code
-typedef process_msg< gather::ostream_like::return_str<>, write_to_file> processor;
-level::holder_no_ts level_holder;
-
-typedef logger<processor, filter_level<level::holder_no_ts, level::debug> > debug_logger;
-typedef logger<processor, filter_level<level::holder_no_ts, level::error> > error_logger;
-typedef logger<processor, filter_level<level::holder_no_ts, level::info> > info_logger;
-
-debug_logger g_log_dbg( init_both, "dbg.txt", &level_holder );
-error_logger g_log_err( init_both, "err.txt", &level_holder );
-info_logger g_log_app( init_both, "out.txt", &level_holder );
-#define LAPP_ if ( !g_log_app) ; else g_log_app->read_msg().gather().out()
-#define LERR_ if ( !g_log_err) ; else g_log_err->read_msg().gather().out()
-#define LDBG_ if ( !g_log_dbg) ; else g_log_dbg->read_msg().gather().out()

/**
@page thread_safety Thread safety
-FIXME
+When talking about thread-safety, there are 2 types of things to consider:
+- the logger class(es)
+- the filter class(es)
+Based on your application, you can fine tune any of the above to suit your needs:
+- use it as single threaded
+- use @ref macros_tss "TSS" (Thread Specific Storage)
+ - use TSS - have some data you modify thread-safe(using mutexes), and have each thread cache the value, and refresh at a given period (very efficient)
+ - initialize your logger/filter only once, and once it's initialized, always use that value (very efficient)
+- thread-safe (use mutexes) - every access uses a mutex; very slow in comparison to the above methods
+
+In addition to the above, for loggers, you can have an even faster method of writing the messages to their destinations:
+@ref writer::on_dedicated_thread "on a dedicated thread".
+
+\n\n
+The easiest way to specify the logger and filter classes, is to @ref scenario::usage "customize the lib to suit your application's needs".
+
+Alternatively, you can @ref defining_your_logger_filter "define them manually":
+- filters:
+ - @c filter::no_ts - single threaded filter
+ - @c filter::ts - thread-safe filter
+ - @c filter::use_tss_with_cache - use TSS: have each thread cache the value, and refresh at a given period
+ - @c filter::use_tss_once_init - use TSS: once the value is set, it will be used by each thread
+- loggers:
+ - <tt>logger<default_, default_, writer::threading::no_ts> </tt> - single threaded logger
+ - <tt>logger<default_, default_, writer::threading::ts_write> </tt> - thread-safe logger
+ - <tt>logger<default_, default_, writer::threading::on_dedicated_thread> </tt> - thread-safe logger, writing on dedicated thread
+
+\n
+Note: I recommend defining loggers manually only if you know the lib very well. Otherwise, choose one of these:
+- @ref scenario::usage "customize the lib to suit your application's needs"
+- @ref defining_your_logger_filter
