    Convert a XBEL document into a HTML directory

    The XML Bookmark Exchange Language, or XBEL, is an Internet "bookmarks"
    interchange format. It was designed by the Python XML Special Interest
    Group on the group's mailing list. It grew out of an idea for a
    demonstration of using Python for XML processing. More information,
    including complete documentation on the DTD, is available.

    See: http://www.python.org/topics/xml/xbel/

    I hope this program is a step towards that goal, besides being useful
    and a non-trivial learning example for me. Use this code in whatever
    manner you like, but give me credit when you use larger amounts of it.

    An example of the resulting output can be viewed at
