The following entry appears to work for programming the Attiny4313 with Avrdude. The previous entry we had here worked, as long as the code didn't cross the 2K border, so make sure you get the latest one posted underneath - which works all the way up to 4K.

We don't take any responsibility for anyone trying this and frying their Tinies or Programmer !! Be sure you know what you are doing.
