naive RNG question

Python's MT documentation exmphasize the period of the 
MT19937 algorithm but discusses not at all the seed size.
The numpy documentation contains no commentary (I believe).
Speaking from a position of utter RNG ignorance, seed size
seems really important too: why is it not discussed?
I noticed this algorithm
http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/MT2002/emt19937ar.html
provides explicitly for seed size choice, which suggests
that some documentation in this area would not be irrelevant
(and also addresses some other interesting technical issues).

Just trying to understand a bit better.
Thanks in advance for any helpful comments or URLs,
Alan Isaac
