     28 ;; Org-Babel support for evaluating Fomus source code.
     29 ;; For information on Fomus see http://fomus.sourceforge.net/
     30 ;;
     31 ;; This differs from most standard languages in that
     32 ;;
     33 ;; 1) there is no such thing as a "session" in fomus
     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
     38 ;;
     39 ;; 4) there are no variables (at least for now)
