MathJax and KaTeX support

I’ve taken a quick look at the hugo code and have seen imports for two markdown processing libs:

I didn’t go further about how they’re being used but, Mmark seems the promissing one regarding this aspect. From their docs:

  • Math support, use $$ as the delimiter. If the math is part of a paragraph it will
    be displayed inline, if the entire paragraph consists out of math it considered display
    math. No attempt is made to parse what is between the $$.

Which looks like resembling the Kramdown feature.
