<h2><a name="SECT001">4.1 Getting and Installing this Package</a></h2>
<p><p>
This package is available at
<p>
<pre>
https://gap-packages.github.io/radiroot/
</pre>
<p>
in form of a gzipped tar-archive. For installation instructions see
Chapter <a href="../../../doc/ref/chap76.html#X82473E4B8756C6CD">Installing a GAP Package</a> in the <font face="Gill Sans,Helvetica,Arial">GAP</font> reference manual.
Normally you will unpack the archive in the <code>pkg</code> directory of your
<font face="Gill Sans,Helvetica,Arial">GAP</font> version by typing:
<p>
<pre>
bash> tar xfz radiroot-2.9.tar.gz # for the gzipped tar-archive
</pre>
<p>
<p>
<h2><a name="SECT002">4.2 Loading and Testing the Package</a></h2>
<p><p>
To use the <font face="Gill Sans,Helvetica,Arial">Radiroot</font> package you have to request it explicitly. This is
done by calling
<p>
<pre>
gap> LoadPackage("radiroot");
-----------------------------------------------------------------------------
Loading RadiRoot 2.9 (Roots of a Polynomial as Radicals)
by Andreas Distler (a.distler@tu-bs.de).
Homepage: https://gap-packages.github.io/radiroot/
-----------------------------------------------------------------------------
true
</pre>
<p>
The <code>LoadPackage</code> command is described in Section <a href="../../../doc/ref/chap76.html#X79B373A77B29D1F5">LoadPackage</a> in
the <font face="Gill Sans,Helvetica,Arial">GAP</font> reference manual.
<p>
If you want to load the <font face="Gill Sans,Helvetica,Arial">Radiroot</font> package by default, you can put the
<code>LoadPackage</code> command into your <code>gaprc</code> file (see Section <a href="../../../doc/ref/chap3.html#X84D4CF587D437C00">The gaprc file</a> in the <font face="Gill Sans,Helvetica,Arial">GAP</font> reference manual).
<p>
Once the package is loaded, it is possible to check the correct
installation by running the test suite of the package with the command
<p>
<pre>
gap> ReadPackage( "radiroot", "tst/testall.g" );
</pre>
<p>
<p>
<h2><a name="SECT003">4.3 Additional Requirements</a></h2>
<p><p>
To use <font face="Gill Sans,Helvetica,Arial">Radiroot</font> the package <font face="Gill Sans,Helvetica,Arial">Alnuth</font> in version 3.0 or higher
has to be loaded with its interface fully functional.
<p>
In the standard mode a dvi file is created to display the roots of a
polynomial. As default the package uses the command <code>latex</code> searched
for in your system programs to create the dvi file and the command
<code>xdvi</code> to start the dvi viewer. If you can not use this settings you
will have to change the function <code>RR_Display</code> in the file <code>Strings.gi</code>
in the subdirectory <code>lib</code> of the package.
