;; Org-Babel support for evaluating Fomus source code.
|
|
;; For information on Fomus see http://fomus.sourceforge.net/
|
|
;;
|
|
;; This differs from most standard languages in that
|
|
;;
|
|
;; 1) there is no such thing as a "session" in fomus
|
|
;;
|
|
;; 2) we are generally only going to return results of type "file"
|
|
;;
|
|
;; 3) we are adding the "file" and "cmdline" header arguments
|
|
;;
|
|
;; 4) there are no variables (at least for now)
|
