            A brief discussion of the Gun Sight Script format

There are only four commands that a gun sight script understands, so 
thankfully there's not much to learn. The basic four commands should 
be enough to allow the user to draw just about any gun sight imaginable.

The commands are as follows:

COMMAND PARAMETERS              Purpose
------- -------------------     -------------------------------------
C       # (color number)        Select the number of the color to be 
                                drawn next, using the palette presented
                                in the break menu bar as the basis of
                                the color numbers. Note that the color
                                number has nothing to do with the RGB
                                values for the color itself. Color 0
                                simply refers to the first color in the
                                Break palette bar.

L       X1 Y1 X2 Y2             Draws a line in the current color from
                                X1,Y1 to X2,Y2

P       X Y                     Plots 1 pixel at point X,Y in the
                                current color

A       CX CY R S L             Draws an Arc (curve) centered at point 
                                CX,CY with radius R. The curve will be
                                drawn starting at angle S and continuing
                                for L degrees.

Some examples:

C 2                             Selects the third color in the top row
                                of the palette displayed in the Break
                                menu bar. Remember, colors start at 0.

P 200 150                       Changes the pixel at 200,150 to the 
                                current color

L 10 10 390 290                 Draws a line starting 10 pixels to the 
                                right and 10 pixels down from the upper
                                left hand corner of the display to a
                                point 10 pixels to the left and 10
                                pixels up from the bottom right hand
                                corner of the display.

A 200 150 20 0 180              Draws a half circle around the center of
                                the view starting at the 9 o'clock (270
                                degrees) position and moving to the 3
                                o'clock (090 degrees) position. The radius
                                of the circle is 20 pixels.
