Here is my updated code, but how do I look at the documentation from the
CLI for logger, logging or any gem? For example, if I want to look at
Perl docs I use perldoc -f "builtin function" or perldoc -q "F.A.Q."
Finally, what about a central logging block for when at anytime 'raise
StandardError' is called, the script will log to one logfile. Will
anyone suggest code or how to do this?
thank you!
