3.1 Getting and Installing this Package

This package is available at

http://www.icm.tu-bs.de/ag_algebra/software/distler/radiroot

in form of a gzipped tar-archive. For the installation instructions see Chapter Installing a GAP Package in the GAP Reference Manual. Normally you will unpack the archive in the 'pkg' directory of your GAP-Version by typing:

    bash> tar xfz radiroot.tar.gz        # for the gzipped tar-archive

3.2 Loading the Package

To use the Radiroot Package you have to request it explicitly. This is done by calling

gap> LoadPackage("radiroot");

Loading  RadiRoot 1.0 (Roots of a Polynomial as Radicals)
by Andreas Distler (a.distler@tu-bs.de).
-----------------------------------------------------------------------------
true

The LoadPackage command is described in Section LoadPackage in the GAP Reference Manual.

If you want to load the Radiroot package by default, you can put the LoadPackage command into your .gaprc file (see Section The .gaprc file in the GAP Reference Manual).

3.3 Additional Requirements

The package Alnuth 2.0 or higher has to be available with its full functionality to use Radiroot.

A dvi file is created to display roots. As default the package uses the command latex searched for in your system programs to create the dvi file and the command xdvi to start the dvi viewer. If you can't use this settings you will have to change the function RR_Display in the file Strings.gi in the subdirectory lib.
