+# (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.
