Can't get Tkinter to run from command line

[Steven Sartorius]

I'm just starting out with Tkinter and have been fooling around with the
following (stored in a file called application.py)....

from Tkinter import *
from ScrolledText import ScrolledText

class gui(Frame):

	def createWidgets(self):
		self.text = ScrolledText(self)
		self.text.pack()

	def __init__(self,parent=None):
		Frame.__init__(self,parent)
		self.pack()
		self.createWidgets()

if __name__ == 'main': gui().mainloop()

This code runs fine from within python itself but I get no window if I
run it from the command line (i.e. python application.py).
I'm sure I'm doing something obviously wrong but what???

Any help much appreciated...

Thanks,

Steve
