Thanks Nikos, but it's not the point. I just need to add to the display 
tree rasters I calculate with python script without G_OPT_OUTPUT because 
I want to name it by script (the name comes from different attributes of 
vector maps). But, it looks that only G_OPT_OUTPUT adds the check box 
"add tree layer" on the script GUI.
