We have this task on our roadmap, for sure. It's just a matter of time...

I don't think it is something difficult. I have worked on such 
autoinstall scripts years ago, and I must say that it's really simple to 
do. I may try to find the few hours necessary to draft something for 
this task.

Sorry, what I meant was that the script should do something like :
 if running on z/OS
    set z/OS properties
else if running on mac OS/X
  then ...

All the properties should be common, and the script should work on every 
Unix/Linux familly. W$ is another beast ;)

That would be just great !
