#15 Easier navigation of generated document
Some browsers, most notably Opera, can interpret link
tags in the header of a document to provide easiy
navigation to the next and previous documents.
It would help users to navigate large documents
produced in complex mode if these tags were added.
For instance:
<link rel="home" href="http://www.opera.com/"
title="Opera front page"/>
Opera will put a button above the window with the label
Home.
It can do the same for next and previous, etc. See: 12.
1.2 Other link relationships <http://www.w3.
org/TR/REC-html40/struct/links.html#h-12.1.2
>
for the W3C recommendations.
Anyway, apart from always wanting more, I'm really
pleased with pdftohtml. It is already saving a lot of time
and effort.

Hi Kevin!
I'm also very pleased with 'pdftohtml', but really missed an
easy way to navigate in the multi page HTML documents. To
remedy this I made a fast hack which adds "Prev" and "Next"
links at the top and bottom of each page generated with
"pdftohtml -c", i.e. with the frame enabled.
The patch against pdftohtml-0.36 is included below!
Regards,
Henrik

As so often with fast hacks, the first try isn't that good.
The first version I posted below does not handle conversions
of documents in subdirectories properly.
The patch included below solves this problem by using the
basename() function.
