  The "contents" and "index" links are probably not too hard to
generate, and appearanly are among the most interesting for many.  I
managed to add support for these for the Python documentation (see the
latest development version using Mozilla with the "Site Navigation
Bar" enabled; http://python.sourceforge.net/devel/docs/lib/lib.html).
There is definately more that could be done (the sectioning support
would be nice!)

  Definately.  The <link> seems potentially very nice to have in
larger documents where the HTML is generated rather than maintained
manually.

  What I did was to use a modified  make_head_and_body()  that
includes the additional elements for rel="first", rel="contents" (when
present), and rel="index" (when present).  That's probably not the
best way to do it; it would be nice to have a set of variables that
could be populated with the right values, and I imagine those could be
handled automatically.  rel="last" should not be hard, but I just
passed on that since I has no idea how to get the right target.
  Note that Mozilla does not currently handle things like multiple
rel="index" links properly; it just uses the first one.  This is
covered by an existing bug report.

  This should not be too difficult for someone who understands more
than I about the LaTeX2HTML implementation.  But I could be wrong.  ;-)
