- # Dateentry
- # ----------------------------------------------------------------------
- # Implements a quicken style date entry field with a popup calendar
- # by combining the datefield and calendar widgets together. This
- # allows a user to enter the date via the keyboard or by using the
- # mouse by selecting the calendar icon which brings up a popup calendar.

- #
- # option -int yes sets dates to YYYY-MM-DD format
- # -int no sets dates to MM/DD/YYYY format.
