.SH DESCRIPTION
This program animates a puzzle called Rubik's Mirror Blocks.
The moves are chosen randomly.
.SH OPTIONS
.I rubikblocks
accepts the following options:
.TP 8
.B \-\-window
Draw on a newly-created window.  This is the default.
.TP 8
.B \-\-root
Draw on the root window.
.TP 8
.B \-\-window\-id \fInumber\fP
Draw on the specified window.
.TP 8
.B \-\-install
Install a private colormap for the window.
.TP 8
.B \-\-visual \fIvisual\fP\fP
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.
.TP 8
.B \-\-delay \fImicroseconds\fP
How long to pause between frames.  Default is 20000, or 0.02 second.
.TP 8
.B \-\-texture
Use texture maps.  This is the default.
.TP 8
.B \-\-no\-texture
Use solid colors.  Looks a bit weird.
.TP 8
.B \-\-mono
Disable both texture maps and colors.  Ditto.
.TP 8
.B \-\-wireframe
Only draw outlines.  Outlines of each piece, not only the whole object, are drawn.
.TP 8
.B \-\-spin
Spin the whole object around X, Y and Z axes.  This is the default.
.TP 8
.B \-\-no\-spin
Do not spin, stay in the same tilt all the time.
.TP 8
.B \-\-wander
Move the object around the screen.  This is the default.
.TP 8
.B \-\-no\-wander
Keep the object centered on the screen.
.TP 8
.B \-\-randomize
Shuffle the puzzle randomly at startup.  This is the default.
.TP 8
.B \-\-no\-randomize
Do not shuffle at startup, begin at the shape of cube.
.TP 8
.B \-\-spinspeed \fInumber\fP
The relative speed of spinning.  Default is 1.0.
.TP 8
.B \-\-rotspeed \fInumber\fP
The relative speed of the moves.  Default is 3.0.  Setting to \(<= 0.0
makes the object stay at one configuration.
.TP 8
.B \-\-wanderspeed \fInumber\fP
The relative speed of wandering around the screen.  Default is 0.02.
.TP 8
.B \-\-wait \fInumber\fP
How long to stay at final position after each move.  The meaning of
the argument is again relative.  Default is 40.0.
.TP 8
.B \-\-cubesize \fInumber\fP
Size of the object.  Value of 3.0 fills roughly all the screen.
.TP 8
.B \-\-fps
Display the current frame rate, CPU load, and polygon count.
.SH ENVIRONMENT
.PP
.TP 8
.B DISPLAY
to get the default host and display number.
.TP 8
.B XENVIRONMENT
to get the name of a resource file that overrides the global resources
stored in the RESOURCE_MANAGER property.
