Helps with mapping tools and commands to Hubot.

export default function createHelpCommand() {
    return {
        name: "help",
        alias: ["?", "/?", "--help"],

                .helpCommands()
                .filter(cmd => cmd.startsWith("hubot " + context.tool.name))
                .map(cmd => cmd.replace(/hubot/g, botName));
            helpCommands.sort();
            if (helpCommands.length === 0) {
                if (noHelpMsg) {
