• Windows
  Run the installer and follow the instructions. Use the desktop icon or startmenu to start the program. Installing the Playermanager is optional.
• Mac
  Mount the disk image in Finder and drag&drop the glGo and the Playermanager icons into your Applications folder. The Playermanager is optional. glGo requires Mac OS X 10.3 "Panther". As I don't have OS X 10.4 "Tiger" myself, I cannot comment on compatibility issues at the moment.
• Linux
  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  Note to users of SuSE Linux (and possibly others): SuSE ships with an outdated expat library.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"

See the Install file for detailed information or have a look at the manual.
