[Mac OS X] How to create double-clickable Python scripts

[Markus]

Hello,

I've written a couple of Python scripts on OS X that I would like to 
start from the Finder by doing a double-click on them. I guess I have to 
create a Package.

Does anybody know an easy way to create such a package? Or where can I 
find more information about how to do this manually?


Thanks,

Mark
