;;; Commentary:

|
|
;; Org-Babel support for evaluating gnuplot source code.
|
|
;;
|
|
;; This differs from most standard languages in that
|
|
;;
|
|
;; 1) we are generally only going to return results of type "file"
|
|
;;
|
|
;; 2) we are adding the "file" and "cmdline" header arguments
|
|
|
|
