-.SH NAME
-slidescreen - permute the screen image like an 8-puzzle
-.SH SYNOPSIS
-.B slidescreen
-[\-display \fIhost:display.screen\fP] [\-background \fIcolor\fP] [\-grid-size \fIpixels\fP] [\-ibw \fIpixels\fP] [\-increment \fIpixels\fP] [\-delay \fIusecs\fP] [\-delay2 \fIusecs\fP] [\-window] [\-root] [\-install] [\-visual \fIvisual\fP]
-.SH DESCRIPTION
-The \fIslidescreen\fP program takes an image of the screen, divides it into
-a grid, deletes a random square of that grid, and then randomly slides
-one of the neighbors of this "hole" into the hole (and repeat.)
-.SH OPTIONS
-.I slidescreen
-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 \-install
-Install a private colormap for the window.
-.TP 8
-.B \-visual \fIvisual\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 \-grid-size \fIpixels\fP
-The size of the grid cells. Default 70 pixels.
-.TP 8
-.B \-ibw \fIpixels\fP
-The size of the "gutter" between grid cells. Default 1 pixel.
-.TP 8
-.B \-increment \fIpixels\fP
-How many pixels by which a piece should be moved when sliding to a new
-location. Default 10 pixels.
-.TP 8
-.B \-delay \fImicroseconds\fP
-How much of a delay should be introduced between steps of the animation of
-the motion of each segment. Default 50000, which is 0.05 seconds. This
-is closely related to the \fI\-increment\fP parameter.
-.TP 8
-.B \-delay \fImicroseconds\fP
-How much of a delay should be introduced between the end of the motion of
-one segment and the beginning of the motion of another. Default 1000000,
-which is one 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.
-.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.
