[Reposting due to justified requests for extra info -- sorry
for being too skimpy the first time around!]

"GMP is a free library for arbitrary precision arithmetic,
operating on signed integers, rational numbers, and floating
point numbers" -- stands for "GNU Multiple Precision"
arithmetic library, lives at

gmpy (General Multiprecision PYthon arithmetic stuff)
is (initially) a Python 2 module interfacing to GMP 3,
and lives at

It's based on C sources originally by AMK and Niels
Möller (for earlier GMP and Python releases, and only
exposing arbitrary-precision-integers functionality).

Current gmpy version is 0.1 (pre-alpha): only exposes
mpz (integer) and mpf (float) types, not yet mpq
(rationals), from GMP.  gmpy comes with a "found on
the net" GMP.LIB for Win32/MSVC++6 (from site,
which is in Japanese, a language I can't, alas, read),
and a working gmp.pyd built from it. (In a separate
download from the C-source/doc.txt/ one).

gmpy needs some project-direction decisions pretty
soon (keep types immutable or make them mutable;
use C or C++...), so all interested parties are invited
to visit the sourceforge page & participate/advise.
