     1997       - ``'xelatex'`` -- compilation does tex -> pdf

     1999       - ``'latex'`` -- compilation first tries tex -> dvi -> png and if an

     2039    If the ``engine`` is either ``pdflatex`` or ``xelatex``,  it produces
    20262040    a pdf file. Otherwise, it produces a dvi file, and if the program dvipng is
    20272041    installed, it checks the dvi file by trying to convert it to a png
    20282042    file.  If this conversion fails, the dvi file probably contains
