# Simple script I whipped up to dump MSN Messenger logs in XML to a readable 
# plaintext format. It's not very robust, nor am I sure which versions of MSN
# Messenger it's compatible or incompatible with; I just had a specific 
# conversation I wanted to read, and this was the vehicle to that end.
