+[section How can I prefix each report with `BOOST_CURRENT_FUNCTION` function signature?]
+
+You will need to give a specific format to you stopclock. You just need to concatenate the your specific patter to the default_format of the formatter.
+
+For example, for a stopclock_accumulator the default formatter is stopwatch_accumulator_formatter, this you will need to do something like:
+
+ static stopclock_accumulator<> acc(
+ std::string(BOOST_CURRENT_FUNCTION) + ": " + stopwatch_accumulator_formatter::default_format()
+ );
+ stopclock_accumulator<>::scoped_run _(acc);
+
+
+Some of you will say that this is too long to type just to get the a report. You can of course define your own macro as
+
+ #define REPORT_FUNCTION_ACCUMULATED_LIFETIME\
+ static boost::chrono::stopclock_accumulator<> BOOST_JOIN(_boost_chrono_stopclock_accumulator_, __LINE__)( \
+ std::string(BOOST_CURRENT_FUNCTION) + ": " + boost::chrono::stopwatch_accumulator_formatter::default_format() \
+ ); \
+ boost::chrono::stopclock_accumulator<>::scoped_stop BOOST_JOIN(_boost_chrono_stopclock_accumulator_run_, __LINE__)(BOOST_JOIN(_boost_chrono_stopclock_accumulator_, __LINE__))
+
+
+With this macro you will just ave
+
+ void foo()
+ {
+ REPORT_FUNCTION_ACCUMULATED_LIFETIME() ;
+ boost::this_thread::sleep(boost::posix_time::milliseconds(100));
+ // ...
+ }
+
+[endsect]
+
+[section How can I prefix each report with `__FILE__[__LINE__]` pattern?]
+
+When you want to prefixx with the `__FILE__[__LINE__]` pattern you can follow the same technique as described below:
+
+ #define REPORT_LINE_ACCUMULATED_LIFETIME \
+ static stopclock_accumulator<> BOOST_JOIN(_boost_chrono_stopclock_accumulator_, __LINE__)( \
+ std::string(__FILE__) + "[" + BOOST_STRINGIZE(__LINE__) + "] " + stopwatch_accumulator_formatter::default_format() \
+ ); \
+ stopclock_accumulator<>::scoped_run BOOST_JOIN(_boost_chrono_stopclock_accumulator_run_, __LINE__) (BOOST_JOIN(_boost_chrono_stopclock_accumulator_, __LINE__))
+
+Now you can mix fcntion and line reports as follows
+
+ void foo()
+ {
+ REPORT_FUNCTION_ACCUMULATED_LIFETIME;
+ boost::this_thread::sleep(boost::posix_time::milliseconds(100));
+ {
+ REPORT_LINE_ACCUMULATED_LIFETIME;
+ boost::this_thread::sleep(boost::posix_time::milliseconds(200));
+ }
+
+ }
+
+[endsect]
+[section Can I use an stopclock accumulator which is not static?]
+
+The typical example of stopclock_accumulator is to get statistical measures of the time a function takes for each one of its calls. You an also use stopclock_accumulator to get statistical measures of the time a given loop takes for each one of its laps.
+
+ stopclock_accumulator<> acc(
+ std::string(__FILE__) + "[" + BOOST_STRINGIZE(__LINE__) + "] " + stopwatch_accumulator_formatter::default_format()

+ for (int i=0; i<N; i++) {
+ stopclock_accumulator<>::scoped_run _(acc);
