DESCRIPTION

       Speedmine!

	       Down the speedmine, you'll find speed

	       to satisfy your moving needs;

	       So if you're looking for a blast

	       then hit the speedmine, really fast.

       Speedworm loves you.

       Speedworm likes to bump and grind

       and chase her tail, and dance around

       she really is a funky friend;

       she's made of speed from end to end.

       You can configure stuff either with command-line options or X resources.

OPTIONS

       -display host:display.screen
	       Specifies which X display we should use (see the section DISPLAY NAMES in X(1) for more information about this option).

       -root   Draw on the root window.

       -window Draw on a newly-created window.	This is the default.

       -install
	       Install a private colormap for the window.

       -noinstall
	       Don't install a private colormap for the window.

       -visual visual
	       Specify which visual to use.  Legal values are the name of a visual class, or the id number (decimal or hex) of a specific  visual.
	       Possible choices include

	       default,  best, mono, monochrome, gray, grey, color, staticgray, staticcolor, truecolor, grayscale, greyscale, pseudocolor, direct-
	       color, number

	       If a decimal or hexadecimal number is used, XGetVisualInfo(3X) is consulted to obtain the required visual.

       -worm   Be a happy spastic worm instead of a tunnel.

       -wire   Specifies that the tunnel/worm should always be rendered in wireframe style.

       -nowire Specifies that the tunnel/worm should be rendered normally. Note that tunnel rendering may still temporarily  switch  to  wireframe
	       style when a wireframe bonus is hit, if bonuses are enabled.

       -foreground color
	       Specifies the default foreground color.

       -background color
	       Specifies the default background color.

       -darkground color
	       Specifies the color of the darkest portions of the ground (or the worm's belly.)  The ground/belly is colored by a gradient between
	       darkground and lightground.

       -lightground color
	       Specifies the color of the lightest portions of the ground/belly.  The ground/belly is colored by a gradient between darkground and
	       lightground.

       -tunnelend color
	       Specifies the color of the light at the end of the tunnel.

       -delay microseconds
	       Specifies  the  delay  between  drawing successive frames. If you do not specify -sync, some X servers may batch up several drawing
	       operations together, producing a less smooth effect.   This is more likely to happen in monochrome mode (on monochrome  servers	or
	       when -mono is specified).

       -maxspeed number
	       Specifies  an upper bound on the speed of normal movement. This does not affect the speed that may be attained when hitting a speed
	       bonus.

       -thrust number
	       Specifies the thrust constantly applied. Positive numbers indicate a forwards thrust, negative numbers indicate a backwards thrust.

       -gravity number
	       Specifies the effect of gravity. Larger numbers will increase acceleration downhill and decrease acceleration uphill.

       -vertigo number
	       Specifies to what level the demo should accentuate the curvature and windiness of the tunnel or worm.

       -terrain
	       Continuously generate a fractal terrain to simulate the rockiness of the tunnel walls, or the texture of the worm's skin.

       -noterrain
	       Do not generate terrain. When this option is set, all surfaces are flat.

       -smoothness number
	       When -terrain is set, specifies how smooth the walls or skin are.

       -curviness number
	       Controls how much the generated tunnel (or worm) should curve left and right, and dip up and down.

       -twistiness number
	       Controls how much the generated tunnel (or worm) twists around itself.

       -widening
	       Specifies that the generated tunnel (or worm) may vary in width.

       -nowidening
	       Specifies that the average width should be kept constant.

       -bumps  Indicates that the simulation should take the bumpiness of the ground into account and allow the animation to shake and rattle when
	       travelling over rough ground.  Or that the worm should be allowed to bump around and shake her booty.

       -nobumps
	       Indicates  that the bumpiness of the ground should be ignored, such that the simulation will glide through the tunnel.  Or that the
	       worm should calm down and behave herself.

       -bonuses
	       Indicates that the demo should include bonus events. These include speed bonuses, spins, and changes  of  viewpoint  and  rendering
	       style.

       -nobonuses
	       Indicates that bonuses should not be included in the demo.

       -crosshair
	       Specifies  that	a  gaming style crosshair be drawn on the simulation. This serves little purpose but may make hardcore gamers feel
	       more comfortable.

       -nocrosshair
	       Specifies that no crosshair be drawn.

       -psychedelic
	       Specifies that a psychedelic colormap should be generated. When this is set, the walls and ground of the tunnel	are  drawn  in	an
	       often changing rainbow of colours.

       -nopsychedelic
	       Specifies that a normal colormap should be used, with muted walls and a grey road.
