-   Using this extension you get access to the data from multiple backends
-   (the requests will be dispatched and query results merged from
-   individual database implementations). It is HIGHLY EXPERIMENTAL and
-   it's typically safer to simply merge all page data into one database
-   backend/implementation instead.
-   
-   You should set this up by hand as follows, because order is important:
-   <!php
-     include("plugins/db/any.php");
-     include("plugins/db/dzf2.php");
-     include("plugins/db/ext_multi.php");
-     #-- create
-     $ewiki_db = & new ewiki_database_multi(false);
-     #-- register databases
-     $ewiki_db->all[] = & new ewiki_database_anydb();
-     $ewiki_db->all[] = & new ewiki_database_dzf2();
-   !>
-   
-   If you only load the plugins, the order may not be preserved, so that
-   new page entries go to the wrong backend (typically the first was the
-   active/main database).
-#this should be configureable!
-   
-   If you also want subwiki support, then you should load that plugin
-   after _this_ one.
-#both features could be merged
