receiving a file on app startup

Hey there,

I would like a Cocoa application to accept files on startup. As an 
example - you can drop images onto the photoshop icon which will 
start the application and open the images. As this is not really drag-
and-drop in the sense of what you find via Google, it would be great 
to get some pointers here.

cheers
