+ABOUT EASYGUI
+
+EasyGui provides an easy-to-use interface for simple GUI interaction
+with a user.  It does not require the programmer to know anything about
+tkinter, frames, widgets, callbacks or lambda.  All GUI interactions are
+invoked by simple function calls that return results.
+
+@note:
+WARNING about using EasyGui with IDLE
+
+You may encounter problems using IDLE to run programs that use EasyGui. Try it
+and find out.  EasyGui is a collection of Tkinter routines that run their own
+event loops.  IDLE is also a Tkinter application, with its own event loop.  The
+two may conflict, with unpredictable results. If you find that you have
+problems, try running your EasyGui program outside of IDLE.
+
+Note that EasyGui requires Tk release 8.0 or greater.
