Since our team does primarily web-based CGI application development, one essential to our work is CGI::Carp, specifically referring to the "CGI::Carp qw(fatalsToBrowser)" function. Without this module, we would have to constantly tail the web server error logs whenever our scripts had a problem in order to determine the actual cause of the error. With this module in place, the error is immediately output to the browser, along with the appropriate content-type headers.
