\Chapter{Installation}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\Section{Getting and Installing this Package}
This package is available at
\begintt
https://gap-packages.github.io/radiroot/
\endtt
in form of a gzipped tar-archive. For installation instructions see
Chapter~"ref: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:
\beginexample
bash> tar xfz radiroot-2.9.tar.gz # for the gzipped tar-archive
\endexample
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\Section{Loading and Testing the Package}
To use the {\Radiroot} package you have to request it explicitly. This is
done by calling
\beginexample
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
\endexample
The `LoadPackage' command is described in Section~"ref: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~"ref: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
\beginexample
gap> ReadPackage( "radiroot", "tst/testall.g" );
\endexample
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\Section{Additional Requirements}
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.
