DESCRIPTION

       chromium-bsu  is  a  fast paced top down arcade style action shooter game.  You progress through the game by destroying everything that you
       see on screen. There are a variety of 'power-ups' to assist you on the way.  There is a big boss to destroy at the end of  each	level  and
       there are various ships to destroy before you reach each boss.

TIPS

       Do not let ANY enemy ships get past your fighters!

       Use your fighters as weapons!

       Strategic suicide is a powerful tactic!

       Self-destruct to preserve your ammunition!

CONTROLS

       The input devices supported depend on the compile options used to build.

       You can control the ship with your mouse, keyboard (arrow keys) or joystick.

ENVIRONMENT

       The following environment variables are used.

       CHROMIUM_BSU_SCORE
	      specifies the location of the user high-score file.

       CHROMIUM_BSU_DATA
	      specifies the location of user-customised game data with the same layout and filenames as the system one.

       CHROMIUM_BSU_FONT
	      When using the GLC backend, this specifies the font name to be used in the menu and the game if available.

	      When using the FTGL backend, this specifies the path to the TTF font file used in the menu and the game.

FILES

       The following files are used.

       ~/.chromium-bsu
	      contains various user preferences.

       ~/.chromium-bsu-score
	      contains the user high-scores.

       ~/.chromium-bsu-music
	      contains a list of music to play during the game.

       ~/.chromium-bsu-data/
	      directory containing user-customized game data with the same layout and filenames as the system one.

       The game will also look in a system directory for data.

CONFIGURATION

       The configuration file is a plain text file. Each line contains a key, a single-space separator and then a numeric value (integer or float-
       ing point).  The following keys are recognised by the game.

       use_playList
	      Enable/disable playlist support. This causes the game to open the ~/.chromium-bsu-music file and play the files listed there.   Dis-
	      abled by default.  Only works when using OpenAL.

	      Enable/disable  CDROM  support.  This  causes  the game to attempt to play any audio CD that might be available. This is disabled by
	      default because the constant spinning up of the CD can be annoying and because CDs are less popular than MP3/OGG	these  days.  Only
	      works when compiled with SDL support.

       full_screen
	      Enable/disable  full-screen  mode. This causes the game to fill the screen instead of just using a window. Disabled by default. Only

       auto_speed
	      Use an alternate speed adjustment algorithm in certain situations. Disabled by default. Only works when using SDL support.
