About this game
===============

Enigma is a tribute to and a re-implementation of one of the most
original and intriguing computer games of the 1990's: Oxyd.  Your
objective is easily explained: find and uncover all pairs of identical
Oxyd stones in each landscape.  Sounds simple?  It would be, if it
weren't for hidden traps, vast mazes, insurmountable obstacles and
innumerable puzzles blocking your direct way to the Oxyd stones...

  Enigma is not nearly finished and help is always appreciated.  If
you enjoy programming, painting, recording sound effects, or designing
levels, you can always join our developers' mailing list at

Playing Enigma
==============

Please refer to the user manual for instructions on how to play
Enigma.


Installation
============

Installation on Windows and MacOS X is straightforward: Simply
download the appropriate .exe or .dmg file and start it with a double
click.

  Things get a little more complicated for other operating systems,
please refer to Enigma's download page

       http://www.nongnu.org/enigma/download.html
       
for up-to-date information.  If you are running some kind Unix system,
you have always the option of compiling Enigma yourself; this is
explained in the next section.

  There may or may not be binaries for your Linux distribution of
choice, and they may or may not work on your computer.  This is not
our fault: packaging a Linux version that works everywhere is almost
impossible--please ask you vendor to make their distribution more
compatible if this bugs you.


Compiling Enigma
================

If you want to compile Enigma from source, you must have the following
programs and libraries installed

    * A C++ compiler
    
      GNU C++ 2.95 and 3.3 are officially supported, older versions won't
      work.  If you use another C++ compiler, your mileage may vary.
      Intel C++ used to work, but we haven't tested it in a long time.
      
    * SDL >= 1.2 (www.libsdl.org)
    * SDL_mixer >= 1.2.4 (http://www.libsdl.org/projects/SDL_mixer)
    * SDL_image >= 1.2.0 (http://www.libsdl.org/projects/SDL_image)
    
      These should already come with most reasonably up-to-date Linux
      distributions.  If you don't have them on your system, please
      download and install them before trying to build Enigma.

Installation should now be as easy as typing

    ./configure && make && make install

in the enigma directory.
