\Chapter{Installation} Installation of the package is fairly easy. Fetch the latest qaos package at \url{http://www.math.tu-berlin.de/~kant/download/gap/qaos.tar.bz2} or via FTP at \url{ftp://ftp.math.tu-berlin.de/pub/algebra/Kant/contrib/gap/} \Section{Installation of the GAP package} If you have permission to add files to the installation of GAP 4 on your system you may install the qaos package into the \file{pkg/} subdirectory of the GAP installation tree. \beginexample shell> cd /path/to/GAP4/installation/tree/ shell> cd pkg/ shell> tar xjf /path/to/qaos.tar.bz2 \endexample This yields another subdirectory called \file{qaos/} with all the necessary files. If you do not have the permission to install the package globally just install it to some private area, for example your home directory. \beginexample shell> cd ~ shell> mkdir mygap shell> mkdir mygap/pkg shell> cd mygap/pkg/ shell> tar xjf /path/to/qaos.tar.bz2 \endexample Now whenever you start GAP, be sure to pass the \file{mygap/} directory to the package search path of GAP. \beginexample shell> gap -l ";$HOME/mygap" \endexample \Section{Installation of cURL} Go to \url{http://curl.haxx.se} and fetch the latest release of cURL for your system. Install it. Refer to cURL installation instructions if necessary. If you have downloaded precompiled binary packages for your system and none of them seem to work, you may also try installing cURL via sources. Just fetch the source archive, unpack it somewhere and say \beginexample shell> ./configure && make && make install \endexample Finally, you can test for a successful curl installation by \beginexample shell> curl http://curl.haxx.se \endexample If this command spits out lots of HTML into your terminal everything is installed properly. If not, adjust your \var{$PATH} variable such that \beginexample shell> which curl \endexample finds a valid path to the curl binary.
