Whoops is a really nice package that's included in the Laravel core. It just provides a wrapper around when your PHP app eventually crashes and shows you where you were an idiot.
It's also a pain to configure. Laravel handles it all internally, and provides no config file to change things. So I changed that.
It's installable using composer (like all good PHP libraries) with
"patrickrose/whoops-configurator": "1.*" in a require block.
Go off and use it!
