        !             3: xdemo - demonstration program for X window system
        !             4: .SH SYNOPSIS
        !             5: .B xdemo
        !             6: [ options ] demo [ =\fIgeometry\fP ] [ \fIhost\fP:\fInumber\fP ]
        !             7: .SH DESCRIPTION
        !             8: .I Xdemo
        !             9: is a demonstration program for the X window system.
        !            10: By default, the host and display number are extracted from the
        !            11: environment variable ``DISPLAY''.
        !            12: One can, however, specify a different display.
        !            13: .I Host
        !            14: specifies the host,
        !            15: and
        !            16: .I number
        !            17: specifies the number of the display.  For example, ``xdemo star orpheus:1''
        !            18: will put the star demo on display one on machine orpheus.
        !            19: Demo can be any of: balls, bounce, circle, circles, colors, cookie, draw, life,
        !            20: lines, menulife, motion, plaid, qix, rgb, shades, slide, star, tetra,
        !            21: wallpaper, web, and xor.
        !            22: The colors, rgb, and shades demos will only work on color displays.
        !            23: .PP
        !            24: The window is created in the usual way using one of the mouse buttons.
        !            25: Using the center button, depress the button to define one corner of the window,
        !            26: move the cursor to where the opposite corner of the window should be
        !            27: and release the button.  Using the right button, depress the button to
        !            28: define the default size window, move the cursor to position the window,
        !            29: and release the button.  Using the left button for all demos but colors,
        !            30: life, and menulife, click the left button to place the default size window
        !            31: in the upper left corner of the screen.  Using the left button for the
        !            32: colors, life, and menulife demos, depress the button to define the default
        !            33: size window, move the cursor to position the window, and release the button.
        !            34: .PP
        !            35: The window can also be placed, or given a default size, with the standard
        !            36: geometry specification:
        !            37: .br
        !            38:        \fB=\fP\fIgeometry\fP
        !            39: .br
        !            40: The geometry specification can be used to set the size and location of the
        !            41: window.
        !            42: See \fIX(1)\fP for details.
        !            43: .PP
        !            44: Most of the demos run without user input: balls, bounce, circle, circles,
        !            45: colors, lines, plaid, qix, slide, star, tetra, wallpaper, web, and xor.
        !            46: Most of these have random number generators built in, and will produce
        !            47: different results each time they are run, or each time the window is
        !            48: resized.
        !            49: .PP
        !            50: .SH "MOUSE USAGE"
        !            51: .PP
        !            52: Mouse usage only applies on the demos draw, life, menulife, motion, rgb, and
        !            53: shades.
        !            54: .PP
        !            55: In the draw demo, clicking the left button defines points that will
        !            56: be connected by a spline when the center button is clicked.
        !            57: If the center button is clicked twice in a row, the window is cleared.
        !            58: Clicking the right button defines points to be connected by straight lines
        !            59: when the center button is clicked.
        !            60: Left and right button clicks can be combined in a single shape.
        !            61: Clicking any button in one of the selection boxes at the upper left selects
        !            62: a drawing mode: patterned gray line, solid white line, solid black line, dashed
        !            63: white line, dashed black line, filled black, filled white, and filled gray.
        !            64: The drawing function can be selected by placing the cursor over the function
        !            65: box at the top right and typing a single hexadecimal digit (corresponding
        !            66: to the characteristic function).  For line drawing, the brush height and width
        !            67: can be adjusted by placing the cursor over the height or width box and typing
        !            68: a single hexadecimal digit.  Text can be put into the picture by positioning
        !            69: the mouse and typing.  The color of the text is determined from the line/fill
        !            70: color, and the display function is applied.
        !            71: .PP
        !            72: The motion demo uses the mouse to define points of a shape just as in the draw
        !            73: demo, but moves the line drawing around the window, bouncing off the walls,
        !            74: while randomly changing the points relative to each other.
        !            75: .PP
        !            76: The life demo uses the left button to randomly insert occupied cells into the
        !            77: window and start the life program initially.
        !            78: Clicking the center button will turn life on and off, so you can look
        !            79: at interesting intermediate patterns,
        !            80: and the right button is used to clear the `universe'.
        !            81: .PP
        !            82: The menulife demo uses the left button to set/clear individual cells while
        !            83: the button is held down.  The right button and the space bar can be used
        !            84: to single step the generations.  The middle button pops up a pull down menu.
        !            85: Release the middle button on a selection for it to take effect; release outside
        !            86: of all selections to abort.  Changing rules takes a long time.
        !            87: .PP
        !            88: The rgb demo uses button operations in the three boxes at the top of the window
        !            89: to change color values.  The left button decrements the value, the right
        !            90: button increments the value.  If you press the middle button and then
        !            91: move around, the vertical position of the mouse controls the value, with zero
        !            92: intensity at the top of the box, and full intensity at the bottom of the box;
        !            93: releasing the mouse button sets the final value.
        !            94: .PP
        !            95: The shades demo uses button clicks to change color values.  A matrix of two
        !            96: primary colors of varying intensity, with a third primary of constant intensity
        !            97: is displayed.  The right button increments the value of the third primary, the
        !            98: left button decrements the value, and the middle button switches to a different
        !            99: pair of initial primaries.
        !           100: .SH OPTIONS
        !           101: On color displays, colors can be specified in the command line:

        !           113: .PP
        !           114: For the following defaults, you can also give a demo-specific default by
        !           115: prepending the demo name and a separating period, e.g., ``Plaid.Foreground''.
