%     subsections in headers; if subsections are long, one can ask for
%     theoremsubsection to number theorems inside subsection. It has lectures
%     number as a margin note.
%   Seminar is a short unstructured document (maybe with paragraph or small
%     subsections).
%   Talk is to prepare a speech - with the same structure as seminar, but is
%     designed to write only the things one will write at the blackboard.
