Detailed Description

Insert standard boilerplate into log messages.

   This class can be used to create your own logtag locally, e.g. inside a
   function.  When inserted into a std::ostream, it will insert the
   standard logtag and some static boilerplate string.  The boilerplate
   string can be constructed by inserting into the localtag itself.
   Sample usage:
   \code

void myfunc() { LocalTag mytag; mytag << "myfunc(): "; std::cout << mytag << "Starting..." << std::endl;

for(unsigned stage = 0; stage < 42; ++stage) { LocalTag stagetag(mytag); stagetag << "stage " << stage << ": "; std::cout << stagetag << "Starting... << std::endl; do_somethin(stage); std::cout << stagetag << "Finished." << std::endl; } std::cout << mytag << "Finished." << std::endl; }
