ror broken links in docs

Is someone aware that the rails complete api doc has broken links?

if I click on actionpack/readme (top right) then off the main page I click 'learn more' for 'Helpers for forms, dates, action links, and text' I get a broke link, there are others

I assume this is already known? if not, can someone write a bot to verify link integrity??

Kind Regards,
