-looks for configuration files and loads them in this order, with the options in
-prior configuration files taking precedence over the same options if they exist
-in multiple configuration files:
-.TP
-1. $YOINKRC
-This is an optional environment variable you can set to point to a configuration
-file.
-.TP
-2. $HOME/.yoinkrc
-This is a specific user's personal configuration file.
-.TP
-3. /etc/yoinkrc
-This is the system-wide configuration file. Not available on Windows.
-.TP
-4. @DATADIR@/yoinkrc
-This is the base configuration file which should be considered read-only. Look
-to this file as an example of the format used for configuration files.
-.PP
-Options that are passed as arguments take precedence over options loaded from
-the configuration file(s). This mechanism is good for running the game with a
-temporary setting which you do not intend to retain. Keep in mind that if you
-edit and save options in-game, any options you have passed as arguments during
-the invocation of the game will be saved to the
-.I $HOME/.yoinkrc
-configuration file. If this is not what you intended, you may have to go into
-that file and remove any options you didn't intend to set. When passing options
-as arguments, you must use the fully qualified name of the option if it exists
-in a subgroup. For example:
-.PP
-.TP
-yoink video.fullscreen=true
-Set the option
-.I video.fullscreen
-to true. This will run the game in full-screen mode.
-.TP
-yoink video.maxfps=60
-Set the option
-.I video.maxfps
-to 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 square brackets and separating each part
-by a comma. For example:
-.TP
-yoink video.mode=[1024,768]
-Set the option
-.I video.mode
-to an array with numbers 1024 and 768. The video size will be 1024x768.
-.PP
-Here is a list of some of the options available:
-.TP
-.B engine.rngseed
-The number value used as a seed for the random number generator. Set this to
-make the game more predictable. This is typically only useful for debugging.
-.TP
-.B engine.timestep
-The amount of time in seconds between each update of the physics state. A value
-of 0.01 or lower is ideal for accurate physics approximations. Values that are
-much higher cause the CPU to do less work, but accuracy will suffer. Errors
-could be introduced in the game with extremely high values.
-.TP
-.B game.detail
-The level of detail. Possible values are high, medium, and low. 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 will omit certain details which aren't crucial for
-playing the game with the benefit of higher frame rates. See the Notes for more
-ways to get good performance.
-.TP
-.B input.grab
-Takes a boolean (true or false). If true, the cursor pointer will be "stuck"
-within the area of the window, and many key combinations which would otherwise
-be handled by the window manager will instead be dropped. This is a low-level
-option of limited usefulness.
-.TP
-.B video.colorbuffers
-This takes an array of four number values which represent the number of bits to
-use for red, green, blue, and the alpha channel. This is a low-level option of
-limited usefulness. The default value is almost always preferable.
-.TP
-.B video.showcursor
-This option effects the visibility of the cursor while it is "hovering" over the
-window. If the value is true, the cursor will be visible. Otherwise, the
-cursor will be hidden.
-.TP
-.B video.doublebuffer
-If true, double-buffering will be used to render animations with minimal
-distortions. Otherwise, a single buffer will be used. The recommended value is
+configfile ("yoinkrc") consists of key-value pairs. They are loaded in this
+order:
+.TP
+1. @DATADIR@/yoinkrc
+This is the base config file which should be considered read-only. Look to this
+file as an example of the format used for config files.
+.TP
+2. /etc/yoinkrc
+This is the system-wide config file. Not available on Windows.
+.TP
+3. $HOME/.yoinkrc
+This is your own personal config file.
+.TP
+4. $YOINKRC
+This is an optional environment variable you can set to the path of a config
+file at a non-standard location.
+.PP
+As usual, options that are passed as arguments take precedence over options
+loaded from the config file(s). Here is a list of some of the options available
+at your disposal:
+.TP
+.B detail
+The level of detail. Possible values are 1, 2, or 3 where 1 means the least
+amount of detail and 3 means 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
+will omit certain details which aren't crucial for playing the game with the
+possible benefit of higher frame rates. See the Notes for more ways to increase
+the game's performance. The default value is 3.
+.TP
+.B doublebuffer
+If true, double-buffering will be used to help minimize distortion and artifacts
+caused by the animation of the game. Otherwise, a single buffer will be used.
+The default value is true.
+.TP
+.B fullscreen
+If true, the window will capture the display and render the game in full screen
+splendor. A value of false means the game will run in a window. The default
+value is false.
+.TP
+.B maxfps
+The maximum number of frames to be drawn per second. If your computer is really
+old, you can get away with decreasing this value and still have reasonably
+smooth animation. You can set this to a very high number to effectively render
+as many frames as is possible, but the actual rate could be limited by vertical
+display synchronization, depending on the X11 driver and settings used. You
+should not set this option higher than the point where the vertical
+synchronization effectively limits the draw rate or else the game may not be
+able to update the physics on schedule which could actually significantly lower
+the quality of the animation. The default value is 40.
+.TP
+.B printfps
+If true, the current number of frames being drawn per second will be printed to
+the console. The default value is false.
+.TP
+.B resizable
+If true, the window will be resizable by the window manager. This option is
+meaningless if the game is drawing to the full screen. The default option is
