 Torbjorn Granlund wrote the original GMP library and is still
 developing and maintaining it.  Several other individuals and
 organizations have contributed to GMP in various ways.  Here is a list
 in chronological order:
    Gunnar Sjoedin and Hans Riesel helped with mathematical problems in
 early versions of the library.
    Richard Stallman contributed to the interface design and revised the
 first version of this manual.
    Brian Beuning and Doug Lea helped with testing of early versions of
 the library and made creative suggestions.
    John Amanatides of York University in Canada contributed the function
    Paul Zimmermann of Inria sparked the development of GMP 2, with his
 comparisons between bignum packages.
    Ken Weber (Kent State University, Universidade Federal do Rio Grande
 do Sul) contributed `mpz_gcd', `mpz_divexact', `mpn_gcd', and
 `mpn_bdivmod', partially supported by CNPq (Brazil) grant 301314194-2.
    Per Bothner of Cygnus Support helped to set up GMP to use Cygnus'
 configure.  He has also made valuable suggestions and tested numerous
 intermediary releases.
    Joachim Hollman was involved in the design of the `mpf' interface,
 and in the `mpz' design revisions for version 2.
    Bennet Yee contributed the initial versions of `mpz_jacobi' and
    Andreas Schwab contributed the files `mpn/m68k/lshift.S' and
 `mpn/m68k/rshift.S' (now in `.asm' form).
    The development of floating point functions of GNU MP 2, were
 supported in part by the ESPRIT-BRA (Basic Research Activities) 6846
 project POSSO (POlynomial System SOlving).
    GNU MP 2 was finished and released by SWOX AB, SWEDEN, in
 cooperation with the IDA Center for Computing Sciences, USA.
    Robert Harley of Inria, France and David Seal of ARM, England,
 suggested clever improvements for population count.
    Robert Harley also wrote highly optimized Karatsuba and 3-way Toom
 multiplication functions for GMP 3.  He also contributed the ARM
 assembly code.
    Torsten Ekedahl of the Mathematical department of Stockholm
 University provided significant inspiration during several phases of
 the GMP development.  His mathematical expertise helped improve several
    Paul Zimmermann wrote the Divide and Conquer division code, the REDC
 code, the REDC-based mpz_powm code, the FFT multiply code, and the
 Karatsuba square root code.  He also rewrote the Toom3 code for GMP
 4.2.  The ECMNET project Paul is organizing was a driving force behind
 many of the optimizations in GMP 3.
    Linus Nordberg wrote the new configure system based on autoconf and
 implemented the new random functions.
    Kent Boortz made the Mac OS 9 port.
    Kevin Ryde worked on a number of things: optimized x86 code, m4 asm
 macros, parameter tuning, speed measuring, the configure system,
 function inlining, divisibility tests, bit scanning, Jacobi symbols,
 Fibonacci and Lucas number functions, printf and scanf functions, perl
 interface, demo expression parser, the algorithms chapter in the
 manual, `gmpasm-mode.el', and various miscellaneous improvements
    Steve Root helped write the optimized alpha 21264 assembly code.
    Gerardo Ballabio wrote the `gmpxx.h' C++ class interface and the C++
 `istream' input routines.
    GNU MP 4 was finished and released by Torbjorn Granlund and Kevin
 Ryde.  Torbjorn's work was partially funded by the IDA Center for
 Computing Sciences, USA.
    Jason Moxham rewrote `mpz_fac_ui'.
    Pedro Gimeno implemented the Mersenne Twister and made other random
 number improvements.
    (This list is chronological, not ordered after significance.  If you
 have contributed to GMP but are not listed above, please tell
 <> about the omission!)
    Thanks go to Hans Thorsen for donating an SGI system for the GMP
 test system environment.
