/* This example shows how to create an AppWindow and obtain arguments

 * will appear on the Workbench screen with the name "AppWindow" and
 * will run until the window's close gadget is selected.  If any icons
 * are dropped into the AppWindow, the program prints their arguments in
 * the Shell window.
