## 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");

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).
