Good idea, this. To do it, the part of Sitemapper you'll want to poke
at is the SmAddPage function. The list of backlinks you should be able
to get from the MakePageList function found in scripts/pagelist.php.
I'd guess that the proper value of for $opt in this case is array(
'link' => 'New.PageName' ) and for $retpages 0 or false, but you
should test that.

Keep in mind that this might end up giving you more hierarchical depth
than you might want, as linking from page A to page B and from there
to page C will add two levels.

I managed to come up with Sitemapper early enough for the sites where
I have it in use that I've been able to give as the suggested pattern
for creating new pages just writing the wanted page name in the
location bar, following the Create ... link on the 404 page, and
trusting Sitemapper to make the page visible.

The whole recipe might benefit from yet another rewrite, but TBH I
can't be bothered as it seems to work well enough for my own use and I
haven't heard too much comment on it from elsewhere.
