+#	Implements the "TK" standard file selection dialog box.  This dialog
+#	box is used on the Unix platforms whenever the tk_strictMotif flag is
+#	not set.
+#
+#	The "TK" standard file selection dialog box is similar to the file
+#	selection dialog box on Win95(TM).  The user can navigate the
+#	directories by clicking on the folder icons or by selecting the
+#	"Directory" option menu.  The user can select files by clicking on the
+#	file icons or by entering a filename in the "Filename:" entry.
