"""
inline_latex is a parser that allows regular moin moin wiki syntax,
but also latex style inline formulas like $...$ and latex style
paragraph formulas like $$...$$. Note that in the latter case, you
are (unlike in latex) limited to a single line. If you absolutely
need multiple lines, use the parser directly.
