the hook modifies data in `%links`. Note that doing so will make the hook
be run twice per page build, so avoid doing it for expensive hooks.
+An optional "last" parameter, if set to a true value, makes the hook run
+after all other hooks of its type. Useful if the hook depends on some other
+hook being run first.

## Types of hooks
In roughly the order they are called.
hook(type => "pagetemplate", id => "foo", call => \&pagetemplate);
-[[Templates]] are filled out for many different things in ikiwiki,
-like generating a page, or part of a blog page, or an rss feed, or a cgi.

parameters, and if it will handle this CGI request, output a page and
terminate the program.
-### cgi
+### auth
- hook(type => "cgi", id => "foo", call => \&auth);
+ hook(type => "auth", id => "foo", call => \&auth);
This hook can be used to implement a different authentication method than
the standard web form. When a user needs to be authenticated, each registered
if the name is set to the name of a user who is not registered,
a basic registration of the user will be automatically performed.
+### formbuilder
+
+ hook(type => "formbuilder_setup", id => "foo", call => \&formbuilder_setup);
+ hook(type => "formbuilder", id => "foo", call => \&formbuilder);
+
+These hooks allow tapping into the parts of ikiwiki that use [[cpan
+CGI::FormBuilder]] to generate web forms. These hooks are passed named
+parameters: `cgi`, `session`, and `form`. These are, respectively, the
+`CGI` object, the user's `CGI::Session`, and a `CGI::FormBuilder`.
+
+Each time a form is set up, the formbuilder_setup hook is called.
+Typically the formbuilder_setup hook will check the form's title, and if
+it's a form that it needs to modify, will call various methods to
+add/remove/change fields, tweak the validation code for the fields, etc. It
+will not validate or display the form.
+
+Form validation and display can be overridden by the formbuilder hook.
+By default, ikiwiki will do a basic validation and display of the form,
+but if this hook is registered, it will stop that and let the hook take
+over. This hook is passed an additional named parameter: `buttons` is an
+array of the submit buttons for the form.

### savestate
hook(type => "savestate", id => "foo", call => \&savestate);
#### `template($;@)`

#### `htmlpage($)`
Given a time, formats it for display.
+#### `gettext`
+
+This is the standard gettext function, although slightly optimised.
