LESS Combiner is a little helper to aggregate all your LESS and CSS files in to a singular file that can be compiled to CSS during a build process using grunt or another tool. It also handles utf8 and BOM problems for you.
Example:
lessCombiner.combine({
paths: ['./less/', './more-less/', './3rd-party-css/'],
outputFileName: './build/style.less'
});
