annotations

[durrieu@tantale.cert.fr (Guy Durrieu)]

Hi,

In a precedent message, I wrote:

=>I would like to annotate trees with centaur paths...
=>
=>What would be in this case the correct class to be declared in the
=>{tree}:new_decor call?
=>

More precisely:

I tried the {singleton} class and that seems to work: annotations are
done. But when I try to save annotated trees (with {tree}:save), the
annotations apparently aren't saved; however, when creating the decor,
I do: 

  ({decor}:control path 'sauver t)

What happens?
