Exception stack traces in superdevmode

The docs/information for how to get stack traces working in superdevmode are very, very poor.

By the sound of it, the two options are:

(1) Deobfuscate your stack traces on the server (see StackTraceDeobfuscator) 
(2) Emulated stack traces 

However, I can't get either of these to work in superdevmode. Anybody got some easy steps to follow to get useful output?
