+# tk common file dialogues
+#
+# this module provides interfaces to the native file dialogues
+# available in Tk 4.2 and newer.
+#
+# written by Fredrik Lundh, May 1997.
+#
+
+#
+# options (all have default values):
+#
+# - defaultextension: added to filename if not explicitly given
+#
+# - filetypes: sequence of (label, pattern) tuples.  the same pattern
+#   may occur with several patterns.  use "*" as pattern to indicate
+#   all files.
+#
+# - initialdir: initial directory.  preserved by dialog instance.
+#
+# - initialfile: initial file (ignored by the open dialog).  preserved
+#   by dialog instance.
+#
+# - parent: which window to place the dialog on top of
+#
+# - title: dialog title
