◄Back► ◄Up► ◄Contents► ◄Index► ◄Back► ──────────────────────────────────────────────────────────────────────────── The syntax of the command lines for the components is shown using diagrams called "railroad tracks", in which the component-name and its options are shown joined by lines indicating the order they should be written in. You read these diagrams left-to-right. Each diagram starts with ►► and ends with ►◄. Sometimes the track forks to show alternatives and then joins up again. The length of a track has no significance. The topic you see when you select a component is its Summary, showing its function, command line syntax, and a very brief description of its parameters. On the button bar is a button to toggle between Summary and Details. The Details describe the parameters fully and give additional information. If this is not needed the Details topic is blank. -♦-
