.SH DESCRIPTION
The \fIslip\fP program does lots of blits and chews up your screen image.
.SH OPTIONS
-.I flame
+.I slip
accepts the following options:
.TP 8
.B \-window
The colors used cycle through the hue, making N stops around
the color wheel.
.TP 8
-.B \-iterations \fIinteger\fP
-How many fractals to generate. Default 25.
+.B \-count \fIinteger\fP
+How many whooziwhatsis to generate. Default 35.
.TP 8
-.B \-points \fIinteger\fP
-How many pixels to draw for each fractal. Default 10000.
+.B \-cycles \fIinteger\fP
+How long to frobnicate. Default 50.
.TP 8
.B \-delay \fImicroseconds\fP
-How long we should wait between drawing each fractal. Default 50000,
+How long we should wait between drawing each step. Default 50000,
or about 1/20th second.
-.TP 8
-.B \-cycles \fIinteger\fP
-How long to frobnicate. Default 50.
+.SH RESOURCES
+On some systems (currently, only SGIs), this program can, instead of grabbing
+a desktop image, grab a frame of video from an external camera and manipulate
+that instead. The following resources control that.
+.PP
.TP 8
-.B \-count \fIinteger\fP
-How many whooziwhatsis. Default 35.
+.B grabVideoProbability \fR(Float)\fP
+What portion of the time to grab video rather than a screen image,
+between 0.0 and 1.0. Defaults to 0.5, or half the time.
+.TP 8
+.B videoDevice \fR(Integer)\fP
+The number of the default video input device to check first. If unspecified,
+the default camera (from videopanel(1)) will be checked first. After that, all
+other available video input devices will be checked in order.
+The first one which produces a non-black image will be used. If all images
+are black, the others will be re-checked a few times before giving up and
+falling back to simply grabbing a desktop image (but note that this takes a
+few seconds, so if you don't actually have any video sources hooked up, you
+should consider turning off video grabbing by setting
+\fBgrabVideoProbability\fP to 0.0.)
+.TP 8
+.B videoGain \fR(Float)\fP
+The amount by which to brighten the grabbed image. This defaults to 2.2.
