Use the $iswrite field of the PageStore class to indicate that
the PageStore should be used in preference to wiki.d/ .
If a PageStore has its $iswrite field set to 1, and the PageStore
indicates that the page being written exists in that PageStore,
then PmWiki will write it to that PageStore instead of wiki.d/ .

This is how http://www.pmwiki.org/wiki/Cookbook/SharedPages works
to identify the PageStore where a page should be written instead
of wiki.d/ .
