doc/todo/using_meta_titles_for_parentlinks.html



It is possible to set a Page-Title in the meta-plugin, but that one isn't
reused in parentlinks. This [[patch]] may fix it.

<ul>
<li> I give pagetitle the full path to a page.
<li> I redefine the 'pagetitle'-sub to deal with it.
<li> to maintain compatibility for IkiWikis without the meta-plugin, i added a 'basename' to the Original-pagetitle.
</ul>
