Here's a good function header given the following:
I wrote the below code

    def mock_kpsewhich(filename):
        nt.assert_equal(filename, 'breqn.sty')
        return None
    with patch.object(latextools, 'kpsewhich', mock_kpsewhich):
        nt.assert_equal('\n'.join(latextools.genelatex('x^2', True)), '\\documentclass{article}\n\\usepackage{amsmath}\n\\usepackage{amsthm}\n\\usepackage{amssymb}\n\\usepackage{bm}\n\\pagestyle{empty}\n\\begin{document}\n$$x^2$$\n\\end{document}')

What's a good function header?
