Accepts_nested_attributes_for in rails 2.2.2?

Hi all

I’m using rails 2.2.2 in one of my apps, and upgrading isn’t an option
at the moment. I’d really like to use the functionality of
accepts_nested_attributes_form, which was added after 2.2.2. Is it
available in plugin form? i know that features often exist in
plugin/gem form before being incorporated into rails core.
