Droplets: Processing dropped files and folders

[zane]

From the Mac Automation Scripting Guide:

Droplets are applets configured to process dropped files and folders. … To create an AppleScript droplet, include an open event handler in your script and save the script as an application. To create a JavaScript droplet, include an openDocuments function in your script and save the script as an application. The presence of this handler or function automatically renders the saved application as a droplet, allowing it to accept dropped files and folders in the Finder.

Should we add support for ClojureScript dropplets to obb, and if so what should the API be? Thoughts about implementation?
