Hands dirty on freerunner.edc file , where to begin.

[David Samblas]

Hi there, 
I want to "simply" add a button/gadget/widget (whatever is called in
illume) beside the "qwerty" button than launch an script that  rotate
the screen.

but after decomplile the  illume-config.edj file I found it a little bit
more complex than expected :/ 

I have found where and how the kdb stuff is defined but I don't see any
clear example on the code that call an external script, all seems
internall calls to parts of the same edc file?

Any light on this for this poor newbee?

Regards
