95
97 The configuration file is a plain text file. Each line contains a key,
98 a single-space separator and then a numeric value (integer or floating
99 point). The following keys are recognised by the game.
100 use_playList
102 Enable/disable playlist support. This causes the game to open
103 the ~/.chromium-bsu-music file and play the files listed there.
104 Disabled by default. Only works when using OpenAL.
105 use_cdrom
107 Enable/disable CDROM support. This causes the game to attempt to
108 play any audio CD that might be available. This is disabled by
109 default because the constant spinning up of the CD can be annoy‐
110 ing and because CDs are less popular than MP3/OGG these days.
111 Only works when compiled with SDL support.
112 full_screen
114 Enable/disable full-screen mode. This causes the game to fill
115 the screen instead of just using a window. Disabled by default.
116 Only works when using SDL support.
117 true_color
119 Enable/disable 24-bit color. When disabled it uses 16-bit color.
120 Disabled by default. Only works when using SDL support.

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

128 tions. Disabled by default. Only works when using SDL support.
