Prototype Legacy Helper
Plugin that adds support for certain Prototype-specific helper methods that were present in Rails versions before 3.0.

This plugin adds supports for the following methods, among others: button_to_remote, submit_to_remote, link_to_remote, form_remote_tag, remote_form_for, periodically_call_remote.
