+# tk common colour chooser dialogue
+#
+# this module provides an interface to the native color dialogue

+# fixed initialcolor handling in August 1998
+#

+#
+# options (all have default values):
+#
+# - initialcolor: colour to mark as selected when dialog is displayed
+#   (given as an RGB triplet or a Tk color string)
+#
+# - parent: which window to place the dialog on top of
+#
+# - title: dialog title
