26 * This plugin shows the current page-level metadata and gives an
27 * entry box for adding a new field or changing an existing one. (A
28 * field can be deleted by specifying a blank value.) Certain fields,
29 * such as 'hits' cannot be changed.
31 * If there is a reason to do so, I will add support for revision-
32 * level metadata as well.
34 * Access by restricted to ADMIN_USER
36 * Written by MichaelVanDam, to test out some ideas about
37 * PagePermissions and PageTypes.
39 * Array support added by ReiniUrban.
