-   Beware, this is a fun plugin!  It is supposed to work, but not
-   recommended for seriously big installations.  This database backend
-   stores all your pages in a ZIP file, it requires the standard util
-   "zip" ('pkzip.exe' may not work).
-
-   You must set EWIKI_DB_ZIP and EWIKI_TMP to writable locations (the
-   directory in which the single ZIP file resides must be world-
-   writable).
-   This database plugin is _CASE_INSENSITIVE always, hit counting isn't
-   done. Eventually you even have to create an empty ZIP file yourself.
-   And this will only run in UNIX environments!
