  29 ;; Org-Babel support for evaluating asymptote source code.
  30 ;;
  31 ;; This differs from most standard languages in that
  32 ;;
  33 ;; 1) there is no such thing as a "session" in asymptote
  34 ;;
  35 ;; 2) we are generally only going to return results of type "file"
  36 ;;
  37 ;; 3) we are adding the "file" and "cmdline" header arguments, if file
  38 ;;    is omitted then the -V option is passed to the asy command for
  39 ;;    interactive viewing
  40 ;;
  41 ;; 4) there are no variables (at least for now)
  42
  43 ;;; Requirements:
  44
  45 ;; - The asymptote program :: http://asymptote.sourceforge.net/
  46 ;;
  47 ;; - asy-mode :: Major mode for editing asymptote files
