397 ;; returns a complete table of contents, `org-ascii--list-listings'
398 ;; returns a list of referenceable src-block elements, and
399 ;; `org-ascii--list-tables' does the same for table elements.
401 ;; The third category includes general helper functions.

403 ;; or inlinetask element. `org-ascii--build-caption' returns the
404 ;; caption string associated to a table or a src-block.
405 ;; `org-ascii--describe-links' creates notes about links for
406 ;; insertion at the end of a section. It uses
