DESCRIPTION
       chromium 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!

ENVIRONMENT
       The following environment variables are used by chromium.

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

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

       CHROMIUM_FONT
	      specifies the location of the font used  in  the	menu  and  the
	      game.

FILES
       The following files are used by chromium.

       ~/.chromium
	      contains various chromium user preferences.

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

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

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

       Chromium 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 floating
       point).	The following keys are recognised by chromium.

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

       use_cdrom
	      Enable/disable CDROM support. This causes chromium 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 annoy‐
	      ing  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  chromium  to  fill
	      the  screen instead of just using a window. Disabled by default.
	      Only works when using SDL support.

       true_color
	      Enable/disable 24-bit color. When disabled it uses 16-bit color.
	      Disabled by default. Only works when using SDL support.

       swap_stereo
	      Enable/disable  swapping sound orientation. Disabled by default.
	      Only works when using OpenAL.

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

       show_fps
	      Print  the  frames  per  second at the top right when in a game.
	      Defaults to enabled.

	      3 = 1024 x  768
	      4 = 1280 x 1024

       gfxLevel
	      Selects the desired amount of  graphical	effects.  Defaults  to
	      full effects.

	      the menu is 1000 times the value in the configuration.  Defaults
	      to 0.03.

       maxLevel
	      The  maximum  level  that	 may be attempted. To attempt the next
	      level you must first complete the maximum level. Defaults to 1.

       volSound
	      Sets the volume of the sound effects. The	 value	shown  in  the
	      menu is 10 times the value in the configuration. Ranges from 0.0
	      to 1.0 and defaults to 0.9.

       volMusic
