As the description says, this script retrieves information about youtube videos from the YouTube API and posts them to the channel whenever a youtube link is posted. You can install it by opening the script editor (Alt+R), creating a new script file (File -> New) and then copy paste the script into it.

Note: Make sure to replace the channels (#foo,#bar) in the on TEXT event line with the channels you want the script to be active in.
