+       hook(type => "renamepage", id => "foo", call => \&renamepage);
+
+This hook is called by the [[plugins/rename]] plugin when it renames
+something. The hook is passed named parameters: `page`, `oldpage`,
+`newpage`, and `content`, and should try to modify the content to reflect
+the name change. For example, by converting links to point to the new page.

+### getsetup
+
+       hook(type => "getsetup", id => "foo", call => \&getsetup);
+
+This hooks is not called during normal operation, but only when setting up 
+the wiki, or generating a setup file. Plugins can use this hook to add
+configuration options.
+
+The hook is passed no parameters. It returns data about the configuration
+options added by the plugin. It can also check if the plugin is usable, and
+die if the plugin is not available, which will cause the plugin to not be
+offered in the configuration interface.
+
+The data returned is a list of `%config` options, followed by a hash
+describing the option. For example:
+
+                return
+                       option_foo => {
+                               type => "boolean",
+                               default => 0,
+                               description => "enable foo",
+                               safe => 1,
+                               rebuild => 1,
+                       },
+                       option_bar => {
+                               type => "string",

+                               description => "what to say",
+                               safe => 1,
+                               rebuild => 0,
+                       },
+
+* `type` can be "boolean", "string", "integer", "internal" (used for values
+  that are not user-visible) or `undef` (use for complex types). Note that
+  the type is the type of the leaf values; the `%config` option may be an
+  array or hash of these.
+* `default` should be set to the default value of the option, if any.
+* `example` can be set to an example value, which will not be used by default.
+* `description` is a short description of the option.
+* `safe` should be false if the option should not be displayed in unsafe
+  configuration methods, such as the web interface. Anything that specifies
+  a command to run, a path on disk, or a regexp should be marked as unsafe.
+* `rebuild` should be true if changing the option will require a wiki rebuild.
