AutoUUE scans a news file for binaries, and automatically decodes them- even if they have been split over several messages.
It then takes all the non binaries and puts them back in your news.
If you subscribe to any usenet binary groups, like alt.binaries.sounds.mods, then this will save you all the hassle of saving them out of TTFN. They will be sitting in a directory waiting for you to just load them into your player.
