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.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 2.4 (Roots of a Polynomial as Radicals) by Andreas Distler (a.distler@tu-bs.de). ----------------------------------------------------------------------------- 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} 2.2.2 or higher has to be loaded with its full functionality available. This means in particular that KANT \cite{KANT} in version 2.4 or 2.5 needs to be installed. 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. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %% %E
