               js: 'js',
               css: 'css'
            },
            js: 'js',
            css: 'css'
        },
        uglify: {
            scripts: {
                expand: true,
                cwd: '<%= path.js %>/',
                src: [
                    '**/*.js', 
                    '*.js',
                    //skip minified scripts
                    '**/!*.min.js', 
                    '!*.min.js'
                ],
                dest: '<%= path.build.src %>/<%= path.build.js %>/',
                rename: function (destBase, destPath) {
                    return destBase + destPath.replace('.js', '.min.js');
                }
            }
        },
        //same options for css minify
        cssmin: {
            styles: {
                expand: true,
                cwd: '<%= path.css %>/',
                src: [
                    '**/*.css',
                    '*.css',
                    //skip minified styles
                    '**/!*.min.css', 
                    '!*.min.css'
                ],
                dest: '<%= path.build.src %>/<%= path.build.css %>/',
                rename: function (destBase, destPath) {
                    return destBase + destPath.replace('.css', '.min.css');
                }
            }
        },
        //and watch it for changes
        watch: {
            js: {
                files: [
                    '<%= path.js %>/*.js',
                    '<%= path.js %>/**/*.js'
