Getting "out" and "dir" options are incompatible message while only "dir" is specified

Hi,

I am not sure if multiple file optimization is supported. But when I try to optimize multiple files based on a given AMD module with below config, I got this "dir" and "out" incompatible error. As you can see from the config, I did not even specify the out option.

var requirejsConfig = {
baseUrl: './src',
paths: {
"knockout":"../lib/knockoutjs/dist/knockout.debug",
"jquery": "../lib/jquery/dist/jquery",
"bootstrap": "../lib/bootstrap/dist/js/bootstrap",
"jqueryui": "../lib/jqueryui/jquery-ui",
"text": "../lib/requirejs-text/text",
"komapping": "../lib/knockout-mapping/knockout.mapping"
},
shim: {
"bootstrap": ["jquery"]
},
dir: '../dist/knockout.modal.min',
modules: [
{
name: 'ModalBinding',
exclude: [
"jquery",
"knockout",
"jqueryui",
"bootstrap",
"text",
"komapping"
]
}
]
};

gulp.src("src/**/*.js")
    .pipe(rjs(requirejsConfig));
