The Eidolon::Debug package provides an easy way to avoid a confusing Internal Server Error web server message. It sends HTTP header before displaying an error, so you don't need to dig web-server's log to find the cause of the error anymore. Obviously, it will do nothing if error is in your web-server configuration, so if Internal Server Error message still remains, check your web-server configuration. Also, this package displays a stack trace when application dies. It is very useful in application development, so Eidolon::Debug is included in applications by default.
This package doesn't depend on any other Eidolon package, so you can use it outside Eidolon applications too.
