The file "sitemap.php" is attached. It goes in the lib directory, with 
an appropriate change to index.php to make it accessible.

I haven't done a lot of PHP programming yet, so if my style is not too good,
please tell me how I could make it better.

This looks like exactly what I want.

I'm not clear on this. Are you assuming that every page had a site-map link
with itself at the root, or would this still be a problem if every page 
had an identical site-map link with the front page at the root? 

I never seriously intended the sitemap function to go on every page. I just
made it flexible so that you could put the root wherever you wanted it.
