[Tutor] how to read HyperText documentation?

[Pijus Virketis]

I am playing around with the HTML generator program, HyperText right now,
but I cannot get to its documentation. The author says that it's at
HyperText.HTML40.__doc__. Sure enough, if I import HyperText, and check
dir(HyperText), there is a __doc__ module there. But I do not know how to
get to the info inside. I tried printing __doc__ (ans: None), executing it,
assigning it to a variable, etc. Could anyone help me out?

Thanks, 

Pijus
