      README FILE FOR SINGULAR MacOS DISTRIBUTION
      ============================================

IMPORTANT: Please see the COPYING file contained in this directory
for license information for Singular.

This distribution contains the following subdirectories
  'share/Singular'      -- contains Singular library files and compute tables
  'info'                -- contains Singular's info help file
  	
and the file
  'COPYING'     -- for licence and copying information information
  'README'      -- this file
   Singular     -- Singular executable program


Installing the Singular executable program
==========================================
1.) Download the file Singular-1.1.ppc.sea.hqx  or
    Singular-1.1.68k.sea.hqx depending on your Macintosh version.

2.) Expand the downloaded file using a standard Expander (like Compact 
    Pro or StuffIt) to obtain the corresponding self-extracting
    Singular-1.1.[ppc,68k].sea file.

3.) Click on the self-extracting Singular-1.1.[ppc,68k].sea file. This 
    will create a new folder named "Singular" which contains the
    Singular program.

4.) Clicking on the Singular program, starts up the MPW shell. Typing
    in "Singular" will start the Singular program.

Overview of Singular
====================
Singular is a special-purpose computer algebra system for commutative
algebra, algebraic geometry and singularity theory. The main features
of Singular are: 

 * Computations in very general rings (polynomial rings, localizations
   of rings at a prime ideal, tensor products of rings) over many
   ground fields (rational numbers, mod p numbers, Galois fields,
   transcendental/algebraic extensions) and monomial orderings (all
   standard monomial orderings, including matrix orderings)

 * Very fast standard (resp. Groebner) bases computations

 * Polynomial factorization, resultant, and gcd computations

 * Large variety of implemented related algorithm: FGLM,
   Hilbert-driven, Factorizing Buchberger; Minimal resolutions,
   Primary decomposition; Usual ideal theoretic operations; standard
   combinatorial algorithms.

 * Efficient and flexible communication links based on the MP
   protocol and library

 * Easy-to-use, command-driven user-interface

 * Intuitive, C-like programming language

 * Extensive libraries of procedures, written in Singular's
   programming language

 * Written in C/C++. Available as binary program for common hard- and
   software platforms (including most Un*x variants, MS-DOG, MacOS)
