<a href="ShowExceptions.html">Rack::ShowExceptions</a> catches all
exceptions raised from the app it wraps. It shows a useful backtrace with
the sourcefile and clickable context, the whole <a

<p>
Be careful when you use this on public-facing sites as it could reveal
information helpful to attackers.
