You did not read the install directions.

>Is there any way to emulate that in MacPerl?

Mac::AppleEvents, Mac::AppleEvents::Simple (interface to the other),
macperlcat.pod (Chris' Apple Events tutorial, comes with MacPerl 5.2.0r4,
also at URL below).

    http://pudge.net/macperl/macperlcat.html

Note that macperlcat is due for a major overhaul.  It does not deal with
Mac::AppleEvents::Simple, and will eventually need to deal with Mac::Glue
and hosts of over things.  I might make it into a larger work (maybe a
series of articles that become a series of tutorials?).

But my main priority right now is to get Mac::Glue worked on, and it is
coming along well in my mind (I have yet to start coding again, but that's
OK ... I am taking notes in case I get hit over the head).

Unfortunately, idle handling is not very good right now.  It is at the top
of my TODO list (though I am not that good with C and not intimately
familiar with the code, so I am hoping to get Matthias to fix it :).

Basically, MacPerl makes it hard to do anything while waiting for a reply.

If something is dropped on a droplet, there is data in @ARGV.  That is
basically it.  Otherwise you can populate @ARGV yourself (the code I just
sent with Mac::StandardFile is one way).
