+.UN description
+.SH DESCRIPTION
+.PP
+This program is part of
+.BR "Netpbm" (1)\c
+\&.
+.PP
+\fBppmwheel\fP produces a PPM image of a color wheel of the
+specified diameter inside a white square just large enough to hold it.
+.PP
+The color wheel is based on the HSV color model.  Hues are distributed
+  angularly around the circle and the values and saturations are distributed
+  radially.
+.PP
+You can generate three kinds of color wheel:
+
+.IP \(bu
+Hue-value: Select this with a \fB-huevalue\fP option.
+.sp
+The saturation is 100% everywhere.  The value goes from zero to 100%
+  linearly, from the center of the wheel to the edge.  So the center is black.
+.sp
+Hence, the image consists of all of the secondary colors based on the
+  red, green, and blue primary colors.  A secondary color is one that is
+  composed of light of at most two of the three primary colors.
+
+.IP \(bu
+Hue-saturation: Select this with a \fB-huesaturation\fP option.
+.sp
+The value is 100% everywhere.  The saturation goes from zero to 100%
+  linearly, from the center of the wheel to the edge.  So the center is white.
+
+.IP \(bu
+Ppmcirc: Select this by not specifying any other wheel type option.
+.sp
+The saturation is 100% everywhere.  The value is a strange function of
+  the distance from the center, increasing as the square root of the distance
+  until halfway out, then decreasing as the 8th root of the distance the rest
+  of the way.  We don't know what the point of this is, but it is what the
+  program Ppmcirc by Peter Kirchgessner in 1995 does, and was the only option
+  in \fBppmwheel\fP from its inception in 2003 to 2019.

+
+.UN arguments
+.SH ARGUMENTS
+.PP
+You must specify one non-option argument: the radius of the color wheel
+in pixels.
+.PP
+This is also the height and width of the output image.
+
+  
+.UN options
+.SH OPTIONS
+.PP
+In addition to the options common to all programs based on libnetpbm
+(most notably \fB-quiet\fP, see 
+.UR index.html#commonoptions
+ Common Options
+.UE
+\&), \fBppmwheel\fP recognizes the following
+command line options:
+
+
+.TP
+\fB-huevalue\fP
+  
+This selects a hue-value color wheel.
+.sp
+This option was new in Netpbm 10.86 (March 2019).
+
+.TP
+\fB-huesaturation\fP
+  
+This selects a hue-saturation color wheel.
+.sp
+This option was new in Netpbm 10.86 (March 2019).
+
+.TP
+\fB-maxval=\fP\fIN\fP
+  
+This selects the maxval for the image.  The default is 255.
+.sp
+This option was new in Netpbm 10.86 (March 2019).
