Exercise: Log::Dispatch

---

Take the examples/advanced-perl/log_dispatch.pl and change it so only warnings are printed to the screen. debug messages are printed to a log file. The name of the file should be in the format YYYY-MM-DD.log The log line should include the name file name and the line number where it was called.

Check out the strftime of the POSIX module and see how Log::Dispatch allows you to provide a callback function.
