OS X 10.8 and later only. Apps and some AppleScript applets from this website already have a "Check for Update..." menu command. But for those that don't this applet/droplet can check for the latest version. Double-click to launch and choose an AppleScript via an Open Panel or just drag-and-drop an AppleScript to its icon to initiate the check.
Click the "Visit Website" button to go to the script's entry page at dougscripts.com.
