Testing code highlighting

I'm giving Google's code highlighting library a try

def subsets(elements, size):
    """ Generates all subsets of the given size of the given set.
    """
    if size > 0:
        while len(elements) > 0:
            first = elements.pop()
            for the_rest in subsets(elements.copy(), size-1):
                yield (first,)+the_rest
    else:
        yield ()

The colors are a tad funky, given my choice of background, but it works!

Instructions are here.
