Hello Per,

Sounds good.

Do you know of any documentation for this?  Like exactly what the <link>
names are for each of these?  And the difference between `top' and
`document', and between `next' and `more'?

Section 6.12 of the HTML 4.01 spec has a list:

I guess maybe `more' is like
hitting SPC to read more of the current node?  I wouldn't know how to
implement that.

No, "More" in the context of Mozilla Site Navigation Bar just means
"any other less-common link types".

However, it might be worth considering adding some javascript to
handle info-style keystrokes.  For example, in my online photo-album
I cause 'n' and 'p' to go to the next and previous photo,
respectively.  This obviously isn't 100% portable, but it's an
optional convenience feature, and it works in Mozilla and (at
least) IE 5.2 (Mac version).  For an example, see:
(This also has the Navigation Bar links I'm talking about.)

    I took a look at what was involved in implementing this,
    but it's not clear to me how it should be done.

For next/prev/up, I think the right thing to do is call add_link for the
various cases in node.c (where the <a rel=... stuff is output now).  For
the others (that are document-wide), I guess they'd only have to
output once at the end of the document ...

The problem is that the <link> element can only appear in the
html <head>, so must be done by html_output_head.
