+"""Wrapper functions for Tcl/Tk.
+Tkinter provides classes which allow the display, positioning and
+control of widgets. Toplevel widgets are Tk and Toplevel. Other
+widgets are Frame, Label, Entry, Text, Canvas, Button, Radiobutton,
+Checkbutton, Scale, Listbox, Scrollbar, OptionMenu, Spinbox
+LabelFrame and PanedWindow.
+Properties of the widgets are specified with keyword arguments.
+Keyword arguments have the same name as the corresponding resource
+under Tk.
+Widgets are positioned with one of the geometry managers Place, Pack
+or Grid. These managers can be called with methods place, pack, grid
+available in every Widget.
+Actions are bound to events by resources (e.g. keyword argument
+command) or with the method bind.
+Example (Hello, World):
+import Tkinter
+from Tkconstants import *
+tk = Tkinter.Tk()
+frame = Tkinter.Frame(tk, relief=RIDGE, borderwidth=2)
+frame.pack(fill=BOTH,expand=1)
+label = Tkinter.Label(frame, text="Hello, World")
+label.pack(fill=X, expand=1)
+button = Tkinter.Button(frame,text="Exit",command=tk.destroy)
+button.pack(side=BOTTOM)
