Double-Clickable or "Droplet" Files?

[John Horner]

I was very impressed by Pashua, which allowed me to add an OS X 
interface to a Perl script. But I still have to call the script from 
the command line.

Are there ways to create double-clickable or droplet-style 
applications in OS X, the way I used to in MacPerl on 9?

There was some mention that this could be done with Pashua, but 
either the doco was missing some details or I didn't understand it.

It would be a useful thing to do if writing scripts for other users 
of OS X who are still completely GUI-based.
