Helper function to get the plugins for which we will look for tasks
@param opts
function getPlugins(opts) {
    var batterRootDir = __dirname.replace(delim + 'lib', '');
    var batterTasks = { rootDir: batterRootDir };
    var currentProject = { rootDir: opts.rootDir };
    var plugins = opts.plugins || [];

    // tasks in batter go to the front of the list; current project at the end (i.e. most important)
    plugins.unshift(batterTasks);

    if (batterRootDir !== opts.rootDir) {
        plugins.push(currentProject);
    }

    return plugins;
}
