The program is very easy to use and consist of 3 main functions. The first function only set one layer to black and adjust the rest of the display settings accordingly for generating a proper prototype plot to a printer or document. The second function adjusts all etch layers to black but only display the layer that is selected. If the program is combined with the nsWare pdf writer, you can easily print a pdf document where the holes are shown on the etch layers. After the documentation is created, the function restore color and visibility goes back to the settings before the program was run.
