This package is available at
https://gap-packages.github.io/radiroot/
in form of a gzipped tar-archive. For 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-2.9.tar.gz # for the gzipped tar-archive
To use the Radiroot package you have to request it explicitly. This is done by calling
gap> LoadPackage("radiroot");

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).
Once the package is loaded, it is possible to check the correct installation by running the test suite of the package with the command
gap> ReadPackage( "radiroot", "tst/testall.g" );
To use Radiroot the package Alnuth in version 3.0 or higher has to be loaded with its interface fully functional.
In the standard mode a dvi file is created to display the roots of a
polynomial. 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 not use this settings you
will have to change the function RR_Display in the file Strings.gi
in the subdirectory lib of the package.
