`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.

+ 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",
+ description => "enable foo",
+ safe => 1,
+ rebuild => 1,
+ },
+ option_bar => {
+ type => "string",
+ example => "hello",
+ description => "what to say",
+ safe => 1,
+ rebuild => 0,
+ },
+
+* `type` can be "boolean", "string", "integer", "internal" (used for values
+ that are not user-visible). The type is the type of the leaf values;
+ the `%config` option may be an array or hash of these.
+* `example` can be set to an example value.
+* `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.
