View source for User:Outlyer/neroaacenc k3b plugin

This is a slightly more complete version of the "neroaacenc" script for use with K3B as found in [[K3b and Nero AAC]].

Important: The code here doesn't take the input parameter, so when configuring k3b you must set the command to 
neroaac %f %t %a %c %n %m %y instead of neroaac - %f %t %a %c %n %m %y (note the dash is missing).

Differences:
* <code>set -e</code>: Fail quickly (abort on fail)
* Logfiles, for debugging purposes all output can be easily redirected
* Doesn't set empty tags
