I was thinking the same thing, here's a quick less interpretation i put together of the generator... not sure it's 100% accurate but it should do the job

One would have to wonder why you would choose less.js over sass. In that case, you'd probably have to add support for both (at least it'd probably be requested), which in the end would add to the complexity of this little tool.

I think that's why it's just vanilla CSS...
