This directory contains the routines for a library of C functions which provides a uniform interface for multi-precision computations both in the ring of integers and in the ring of polynomials over finite field. The package is called Arithmetic in Global Fields. It was written by Kevin R. Coombes <kevin@math.lsa.umich.edu> and David R. Grant <grant@boulder.colorado.edu>. It is copyrighted under the terms of the GNU public license---see the files NOTICE and COPYRIGHT in this directory for details. The best place to start is in the directory Doc, which contains manual pages and a user guide written in TeX. You can create and install the libraries by typing "make" while in this directory. You can then go to the Tests directory to try them out. Good luck. Kevin R. Coombes <kevin@math.lsa.umich.edu> David R. Grant <grant@boulder.colorado.edu>
