WARNING: This script is very rough-and-ready. Backup your class files  before letting this loose on them!!!

Download from here...

Use it like this...

mtasc [options etc] 2>&1 | removeimports.py

This redirects stderr to stdout (2>&1) and then pipes the entire lot  to the removeimports.py script.
