"pydoc gmpy" works for me. Not sure how you use pydoc on windows, but
you can do this...
>>> import gmpy
>>> help(gmpy)
Help on module gmpy:
NAME
gmpy
FILE
/usr/lib/python2.3/site-packages/gmpy.so
[snip]
Help on built-in function pi:
pi(...)
pi(n): returns pi with n bits of precision in an mpf object
[snip]
The original gmp documentation is sensible also, since gmpy is really
just a thin wrapper to it. There is also the gmp source code too.
