Installation of the Involutive package and ginv
-----------------------------------------------


The Maple package Involutive is developed at
Lehrstuhl B fuer Mathematik, RWTH Aachen,
http://wwwb.math.rwth-aachen.de, Copyright (C) 2000-2008.
It is available online at
http://wwwb.math.rwth-aachen.de/Janet.

This package implements the involutive basis algorithm
designed by V. P. Gerdt and Y. A. Blinkov and contains
a lot more useful procedures do deal with polynomial
equations.

The following description of the installation process
assumes that you are going to use the package Involutive
in Maple 8 or newer versions of Maple.

1. Create a directory which is supposed to contain
   all files of the package Involutive,
   e.g.  mkdir /usr/local/lib/Involutive.

2. Copy the files Involutive.ind and Involutive.lib into
   the directory chosen in 1.

3. Ensure that the directory which you have chosen in 1.
   is listed in the global Maple variable 'libname'
   (see ?libname in Maple for details).

Then the package can be loaded via

with(Involutive);


The open source software project ginv implements the
involutive basis technique as a C++ module for Python, cf.
http://invo.jinr.ru and

Copyright (C) 2001-2008.
It is developed by V. P. Gerdt, Yu. A. Blinkov, and
Lehrstuhl B fuer Mathematik, RWTH Aachen.
In order to install ginv, extract the contents of
ginv.tgz into a directory and run

python setup.py build

in that directory.

The package Involutive offers an interface to ginv by
the command InvolutiveBasisGINV.
In order to use this interface, the shell script named
runginv needs to be adjusted such that the variable
$PYTHONPATH contains the path where ginv has been
installed. This script runginv should then be copied
into a directory which is included in $PATH.


Thank you for installing Involutive and ginv.
