    ### Creating the CLI argument parser
    parser = ArgumentParser(description="Generates Custom Gcode Required by my PCB Manufacturing Machine :)", 
            formatter_class=ArgumentDefaultsHelpFormatter)

    ### Adding the positional arguments
    parser.add_argument('src', help="Source Gerber file to be converted to Gcode\n")

    ### Adding keyword Arguments
    addArg('dest', "Destination Gcode file", str, 'D')

    addArg('mirrored', "Mirror Given Srouce Gerber file. Used for traces of DIP components", bool, 'M')
    addArg('rotated', "Rotate 90degrees Given Srouce Gerber file. Used for traces of DIP components", bool, 'R')

    addArg('x_offset', "Value PCB offseted from X axis", int)
    addArg('y_offset', "Value PCB offseted from Y axis", int)

    addArg('all_gcode', "Creates a Gcode file with hole drilling gcode, ink laying gcode and laser drawing gcode", bool, 'ALL')
    addArg('holes', "Adds hole drilling gcode to Gcode file", bool)
    addArg('ink', "Adds ink laying gcode to Gcode file", bool)
    addArg('laser', "Adds laser drawing gcode to Gcode file", bool)
    addArg('include_edge_cuts', "Include Edge cuts in laser marking process", bool)
    addArg('laser_passes', "Number of passes for laser marking Gcode", int)
    addArg('debug', "Shows Simulation of the PCB laser trace coordinates as well as other debug Info.", bool)

    addArg('dont_export_gbr', "Doesn't allow exporting of the mirrored_and_offseted gerber file", bool)
    addArg('new_gbr_name', "The name of the newly created Gerber File after mirroring and offsetting", str)

    ### Extracting User inputs!
    # Getting arguments
    settings.settings_dict.update(vars(parser.parse_args()))

    ### Executing the Program!
    main(settings)
