                                                27 February 2003                                       GL-117(6)

gl-117 uses a predefined working directory ".gl-117" in the user's home directory to load and  store  all
       savegame  files and read the plain text configuration files "conf" and "conf.interface".  If there are no
       config files available, gl-117 will create them using standard settings. The contents of  the  files  are
       quite self-explanatory.

gl-117 is distributed under the terms of the GPL.

gl-117  is  an OpenGL and SDL based action flight simulator written in ISO C++.  Enter the Eagle Squadron
       and succeed in several challanging missions leading though different landscapes.  Five predefined  levels
       of  video quality and an amount of viewing ranges let you perfectly adjust the game to the performance of
       your system.  The game provides joystick and mouse support, sound effects, and music.

       Please  look  at  the  gl-117 user manual (gl-117.pdf) for installation instructions and further gameplay
       related descriptions.
