+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.
