Adaptation of METIS for Code_Aster purpose :
============================================

A warning has been included in modified files

/* WARNING : This file has been modified for Code_Aster */
/*           http://www.code-aster.org                  */

The original distribution of METIS can be found at
  http://www-users.cs.umn.edu/~karypis/metis/index.html


Installation instructions :
===========================
   1. Run : make 

   The Makefile does :
      . Configure compiler and loader options : create Makefile.in
        (If your platform is not recognized, you must edit CONFIG/configure)
      . Change to Lib dir ; launch Makefile : create libmetis.a
      . Change to Program dir; launch Makefile : create onmetis.exe, pmetis
        and kmetis
      . Change to Test dir ;  launch Makefile : run onmetis on a small test
        and print version label

   2. Installation :
      If Code_Aster is already installed, add a symbolic link to onmetis
      script in your Code_Aster tools directory,
      (if not, the installation script of Code_Aster should add a such link)


Using METIS for Code_Aster :
============================

This is onmetis binary (renamed onmetis.exe) which is called by Code_Aster
through the onmetis shell-script. pmetis and kmetis are called directly.
The onmetis script, pmetis and kmetis executables have to be copied (or make a
symbolic link to) into Code_Aster tools directory (generally it looks like
.../aster/outils).
