Install the .rpm and .deb files like you would install any package of each type: "rpm -i glGo-1.4.1.rpm" or "dpkg -i glGo-1.4.1.deb". The .tar.gz archive contains scripts to install and remove glGo. Unpack it somewhere and run "sh glGo.install" as root or using sudo. glGo requires Python 2.4 installed. Note to users of SuSE Linux (and possibly others): SuSE ships with an outdated expat library. If glGo fails to start due to missing libexpat.so.1, do the following as root: "cd /usr/lib" "ln -s libexpat.so.0.5.0 libexpat.so.1"
