Version 3.1 does work the same way - it's basically based on call back
functions. What might be a bit confusing is that 3.1 is a mix between the
original version of call back functions and the one provided by Charlie Brooks
for extending it to work on NT. I have now cleaned this up and it will get out
in the next version so it hopefully is a lot easier to find out.
