How to unpack the program: On Mac OS X, Linux and other UNIX-like systems: 1. Open up a terminal window. 2. Change directory to whereever you placed the package. 3. Run the command "tar xfvj The_Star_of_Africa-[version].tar.bz2" On Windows: 1. If you do not have a program capable of handling bz2-archives, you can download one at http://www.7-zip.org (It's free.) 2. Install the program, and unpack the archive with it. How to run the program: All operating systems: 1. Make sure you have a java runtime environment (v 1.6 or later) installed. If you do not, you can download one from here: http://www.java.com/en/download/manual.jsp (It's gratis.) 2. Try double-clicking on the file "The_Star_of_Africa.jar". This should work at least on Windows and Linux with Gnome desktop environment. If it doesn't work, proceed to step 3. 3. Open up a terminal window (that's run -> cmd for Windows users). 4. Change directory to the one that holds the files you just extracted 5. Run the command "java -jar The_Star_of_Africa.jar" Since running the program in this manner can be a bit cumbersome to do every time you want to play, you'll probably want to set up an icon in the program menu, or on the desktop that executes the command from step 5 when clicked. If you're interested in the source code, it can be found at http://miria.homelinux.net/the_star_of_africa/ You can also go there to check whether you have the latest version or not, sine this is the first place any new version will appear. Have fun.
