GL-117(6)			 gl-117 overview		       GL-117(6)

NAME
     gl-117 - an OpenGL action flight simulator

SYNOPSIS
     gl-117 [-dlevel -h -v]

DESCRIPTION
     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 qual-
     ity  and  an  amount of viewing ranges let you perfectly adjust the game to
     the performance of your system.  The game provides joystick and mouse  sup-
     port, sound effects, and music.

OPTIONS
     -dlevel
	    Set  the  debug  level  to level in [0..5]. '0' means quiet and will
	    avoid any output, '1' will log fatal errors causing the  program  to
	    crash  on stderr, '2' will also print exceptions on stderr, '3' will
	    add warnings on stdout, '4' prints	additional  information  (prede-
	    fined)  on stdout, and '5' gives developer specific messages on std-
	    out.

     -h     Print a short summary on stdout and then quit immediately.

     -v     Display the version number of gl-117 and then quit immediately.

CONFIGURATION
     gl-117 uses a predefined working directory ".gl-117" in the user's home di-
     rectory to load and store all savegame files and read the plain  text  con-
     figuration 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.

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

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