TimeDead

Hello, sorry if this is in the wrong section... But, I was wondering (Since I'm still relatively knew with Ruby) is there a script or a method I can use for my game to check an online database (Ftp for instance) for any updated files, and then ask the player if they would like to update to the latest version and display current version and then the latest version. Just curious. If anyone can help out it'd be greatly appreciated.
