I seem to remember it was installed by default in OS X 10.4 (Tiger),  
and maybe even without option in 10.5 (Leopard)

You know, (we) mac people can sometimes be a bit obtuse ;). And the  
difference is harder to notice if you come from other platforms.
But I am sure there will be people willing to stand the ugliness /  
lack of integration.

I hope it will be useful for other mac users. So if I can help in any  
way, please let me know.

thisDir="${0%/*}"
(I use that in (inner bundle).*/Contents/MacOS/preJava)
Also, running a bundle is supposed to prepare a couple of variables  
(mapped to environment variables?) pointing to the interesting dirs.  
Try to dump them in the shell to look for them.

Nice weekend!
(please remember to test native libraries' functionality, like loading  
a TIFF. And some screenshots would be very interesting - is it Aqua- 
like or Metal-like?)
