This is a small module accompanying the CGI module, providing the display of an
error screen (somewhat resembling the classical red-on-black blinking Guru
Meditation from the good-old AmigaOS before version 2.04) in case of abnormal
termination of a CGI.

The module simply installs a $SIG{__DIE__} handler which sends a HTTP response
showing a HTML/CSS based screen which optionally includes the Perl run-time
error message, an excerpt from the CGI source code and the Perl run-time
environment variables. This provides both optically more pleasant and
functionally more elaborate error messages for CGIs.

This module supports both the regular CGI and the Apache/mod_perl CGI
environment.
