If you have CLIM, and load one of the CLIM fasls, you can use the
function DRAW-URLPATH-TREE to get pictures of your trees:

    Draw a picture of a URLPATH tree.
    TREE is something maed by MAKE-UPT.
    UNRESOLVED-POINTER-PREDICATE, if given, takes a PAGE-ATTRIBUTES
    object and a tree (TREE in fact) and should return T is there are
    unresolved pointers.  There is a default which works.
    DESCRIBER-FUNCTION, if given, takes a PAGE-ATTRIBUTES object, a
    tree, and a stream, and should print some useful information on
    the stream.  The default does a fairly comprehensive job,
    including some CLIM stuff to make the links be clickable.

    Pages with dangling links are painted red.

    Clicking left on a page name calls the describer function on it.

    On Unix, clicking middle will send the page to netscape -- this will
    only work if the pages are visible in the local filesystem!
