Require.js: use app.js?... cache-busting URL parameter for loaded modules

app.js

(function( libFileName ) {
    var scripts = document.getElementsByTagName( 'script' ),
        i, src, parts, len = scripts.length;

    for( i = 0; i < len; i++ ) {
        src = scripts[i].src;
        if( src.indexOf( libFileName ) != -1 ) {
            parts = src.split( '?' );
            if( parts[1] ) {
                /* set requiresjs config */
                requirejs.config( {
                    urlArgs: parts[1]
                } );
            }
            break;
        }
    }
})( 'app.js' );

This snippet should be inserted right after the requirejs.config() block. Set the argument of the immediately invoked function to the filename of the script that has a cache busting URL parameter.
