+// OS specific file selection dialog. This is implemented as a
+// singleton class, so call the instance() method to get the working
+// instance. When you call getMultipleOpenFile(), it locks the picker
+// until you iterate to the end of the list of selected files with
+// getNextFile() or call reset().
