# 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.

# Modified 2001-10-23 by Mark Alston to pass options to the datefield 
# constructor.  Needed to allow use of new option -int which lets the 
# user use dates in YYYY-MM-DD format as well as MM/DD/YYYY format.
#
# option -int yes sets dates to YYYY-MM-DD format
#        -int no sets dates to MM/DD/YYYY format.
