-There are a plethora of options available for tweaking various aspects of the
-game. All options can be set either from a configuration file or by passing
-them as arguments.

4. $YOINKRC
-This is an optional environment variable you can set to point to a configuration
-file.
-.PP
-Options that are passed as arguments take precedence over options loaded from
-the configuration file(s). This mechanism can be used to play the game with
-temporary settings which you do not intend to retain. Here are some examples of
-passing options on the command-line:
-.PP
-.TP
-yoink fullscreen=true
-Run Yoink with the option
-.I fullscreen
-as true. This will run the game in full-screen mode.
-.TP
-yoink maxfps=60
-Run Yoink with the option
-.I maxfps
-as 60. This will cap the display rate at 60Hz.
-.PP
-You can also set options with array values. Arrays can be passed on the command
-line by surrounding all the parts with curly brackets and separating each part
-by a comma. You may also have to quote the brackets so your shell doesn't parse
-them. For example:
-.TP
-yoink videomode=\\{1024,768\\}
-Run Yoink with the top
-.I videomode
-as the numbers 1024 and 768. The video size will be 1024x768.
+This is an optional environment variable you can set to the path of a config
+file at a non-standard location.

+As usual, options that are passed as arguments take precedence over options

.B detail
-The level of detail. Possible values are 1, 2, or 3, 1 meaning the least amount
-of detail and 3 meaning the most. This effects the number of objects drawn to
-the screen. A high level of detail will draw everything but could cause poor

frame rates if the graphics driver can't keep up with the load. Lower levels

-game's performance. The default value is 3.

.B doublebuffer
If true, double-buffering will be used to help minimize distortion and artifacts
.B videomode
The resolution or size of the window. The value is an array with three number
elements representing the width, height, and bits per pixel that make up the
-video mode. The third number is optional. The default value is {800, 600}.

This is only a list of the more useful options. You'll have to use the source
to find out about the more esoteric options, but you probably won't need to.
