== a) needs conversion to a different markup

Documented I've found two possible ways to explore first:
1. Use moin2rst Formatter https://moinmo.in/FormatterMarket
   and additional scripting to get to rSt and
   then pandoc to convert to something else.

2. Use a html export and then pandoc.

It maybe an advantage if we could convert to a widely used Wikimarkup
like markdown variants. Regarding independence.

Both would require additional scripting.
