The \verb|\VerbMath| command redefines environments to pass their content
verbatim to the HTML output.
+The optional command can contain name of the counter that should be updated.
+It will also use LaTeX 3 regular expressions to search for label commands.
+Thanks to that, cross-referencing to the math environments should work.
+It is a bit limited, for example subequations cannot work. There can be also
+issues in books, where equation numbers are based on chapters, but MathJax
+numbers them consecutively. In these cases, other mechanisms may be necessary.
