Downloading Scratch project to XO

[John Maloney]

Hi, Bert.

Thanks for the help on this.

To clarify, what I was doing was using the clipboard to move a  
downloaded Scratch project file. I dragged it from the Journal to the  
clipboard, then went to the Scratch activity and dropped it onto the  
Scratch window. So that's a somewhat different path from trying to  
open the project directly in the Journal. It would be great to get  
both paths working eventually.

Re: But this retrieval could be done in the Scratch wrapper script.

Cool! That would be an easy solution for me if the wrapper script is  
not too complex. Could you give me a hint about what the wrapper  
script would look like?

Meanwhile, I will try to make the drag-n-drop-from-clipboard solution  
work.
