Apache Easy Debug is CGI/Perl script intended to replace default Internal Server Error Message. With this script installed web developer doesn't need to lookup and scroll web server log after each script error because latest records are nice formatted and displayed just on error page.

The wrapper executes a given script internally and prints out EVERY error to the browser that might occur. Use it when you move perl applications from server to server as well when scripting or adapting perl scripts. It will save you a lot of headache and time especially when you're not allowed to access the webserver's error logfile.
