Examples of org.jnode.shell.help.Help

org.jnode.shell.help.Help
This is the interface for an object that outputs command help. Different implementations support different command syntax mechanisms, and (in the future) will provide help in different output formats; e.g. plain text, HTML and so on. @author crawley@jnode.org

        // We'll show the help for the last command in the pipeline.
        CommandLine cmd = commands.get(len - 1).commandLine;
        CommandInfo cmdInfo = cmd.getCommandInfo(shell);
        if (cmdInfo != null) {
            try {
                Help help = HelpFactory.getHelpFactory().getHelp(cmd.getCommandName(), cmdInfo);
