Actually, this is not difficult.  When a program is launched, the X and Y
registers point to the arguments (if there are any), and are both $0000 if
there are none.  The "Finder" interface is the same for all program launchers
(including ProSEL), which specifies that if Message #1 exists in the Message
Center, it's the pathnames of documents to open.

The MessageCenter chapter of Toolbox Reference and the GS/OS Reference contain
all the information any interested party needs to write such a piece of code.
