Is there an app to automatically remove old versions of Chrome on OS X?

Is there an app to automatically remove old versions of Chrome on OS X?<p><i></i><i></i><p>I saw some information that there was a windows version but not one for mac.<p>http://m.lifehacker.com/5874876/oldchromeremover-frees-up-disk-space-used-by-old-versions-of-chrome<p>If you go to Applications > Right click on Google Chrome > Show Package Contents > Contents > Versions<p>It will show you old versions of Chrome that incrementally eat up storage space.<p>Deleting those old versions doesn't harm the functioning of my current chrome and none of the comments i've read show any negative effects on security updates either.<p>I personally removed 2 GB of old versions going back to January of this year.<p>I have seen applications that automatically do this for Windows, but none for mac. Have you all seen anything that could automate this process?<p>BTW, does Chrome seem to use up a lot of your harddrive space after even moderate usage? This browser seems like a massive resource user.
