Issue1703

The doctest doc locate here:
http://www.jython.org/docs/library/doctest.html
shows example code such as:
if __name__ == "__main__":
    import doctest
    doctest.testmod()
This code fails with error message:
    TypeError: testmod() takes at least 1 argument (0 given)
My guess is that the correct code would read:
    import doctest, thismodule
    doctest.testmod(thismodule)
provided, of course, that the example had been saved in the file thismodule.py

I can't reproduce this. I'd suggest printing doctest.__file__ to ensure that it's being imported from where you think it is. The doctest module that ships with jython doesn't require 1 argument
