.SH DESCRIPTION
-The \fIslip\fP program does lots of blits and chews up your screen image.
+The \fIslip\fP program does lots of blits and chews up an image.
+
+The image that it manipulates will be grabbed from the portion of
+the screen underlying the window, or from the system's video input,
+or from a random file on disk, as indicated by
+the \fIgrabDesktopImages\fP, \fIgrabVideoFrames\fP,
+and \fIchooseRandomImages\fP options in the \fI~/.xscreensaver\fP
+file; see
+.BR xscreensaver-demo (1)
+for more details.
.SH OPTIONS
.I slip
accepts the following options:
or the id number (decimal or hex) of a specific visual.
.TP 8
.B \-ncolors \fIinteger\fP
-How many colors should be used (if possible). Default 128.
+How many colors should be used (if possible). Default 200.
The colors used cycle through the hue, making N stops around
the color wheel.
.TP 8
.B \-delay \fImicroseconds\fP
How long we should wait between drawing each step. Default 50000,
or about 1/20th second.

-.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 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.
+.B \-fps
+Display the current frame rate and CPU load.
