Subject: Not tested

but I think the changed to add logos to help are as below.  Not sure
it deals with the top node but I have not found where that is done.
Also not sure if one can escape " in a string in Standard LISP, or
whether one needs to use the %c or equivalent stuff.  May be that some
of the " as not needed.
