Detailed Description

Tracing outputs starting and finishing messages for some lengthy procedures. Its constructor will output a given string, the destructor will output "finished\\n". That means you have to start a new block and define a local trancing object in there. When entering the block the constructor is called, the start message is printed. When leaving the block the descructor displays the finishing message. For convenience there are some macros defining the local object so you can write:

{ // start a new block
  ACG_TRACE("What's the meaning of like?");

  for (years=0; years <= ACG::NumLimitsT<int>::max(); ++years)
  {
    // ... lengthy computation, show some progress
    ACG_TRACE_PROGRESS;
  }

  std::cout << "42";

} // leaving the block will display "finished\n"

If you want to trace only one command you can also use:

ACG_TRACE_CMD("What's the meaning of like?", calc_meaning_of_life());
