#   * Part of tcllib extension
#   * Tk datefield widget
#
# (The following is the original description of the library.)
#
# The datefield package provides the datefield widget which is an enhanced 
# text entry widget for the purpose of date entry. Only valid dates of the 
# form MM/DD/YYYY can be entered.
# 
# The datefield widget is, in fact, just an entry widget with specialized 
# bindings. This means all the command and options for an entry widget apply 
# equally here.
