By the way, on the above picture you can quite nicely see the effect of 
having a couple of great, dedicated developers work on kaffe in the last 
  months. Thanks to all involved, you know who you are ;)

We should also expand the AUTHORS file, I think, to reflect the recent 
additions to the kaffe developer team. The above picture shows the 
positive effect they took on kaffe's development better than a thousand 
of words :)

cheers,
