  % A~word of explanation: first of all, we
  % close the group for changed |\catcode|s; the directive's text has its
  % |\catcode|s fixed. Then we put the directive's text wrapped with the
  % formatting macro into one macro in order to give just one token
  % the \gmdoc's \TeX\ code scanner.
  % ^^A But before we launch the \TeX\ code
  % ^^A  scanning with all the b\&w, we virtually restore the meaning of
  % ^^A  further |<|s to let them start further \ds\ directives,
  % ^^A  and after this possible restore (if it \emph{actually} takes place
  % ^^A  depends on the declaration used: |\docstrip| or |\docstrips|) we
  % Then launch this big \TeX\ code scanning machinery by calling
  % |\gmd@textEOL| which is an alias for the `narrative' meaning of the
  % line end. This macro opens the verbatim group and launches the
  % char-by-char scanner. That is this scanner because of what we
  % encapsulated the directive's text with the formatting into one
  % macro: to let it pass the scanner.
  %
  % That's why in the `old' macrocodes case the active |%| closes the
  % group before launching |\gmd@docstripdirective|.
  %
  % \stanza
  % The `verbatim' directive macro works very similarly.
