24 | ;;; Commentary: | |
25 | ||
26 | ;; Currently this only works using session evaluation as there is no | |
27 | ;; defined method for executing shen code outside of a session. | |
28 | ||
29 | ;;; Requirements: | |
30 | ||
31 | ;; - shen-mode and inf-shen will soon be available through the GNU | |
32 | ;; elpa, however in the interim they are available at | |
33 | ;; https://github.com/eschulte/shen-mode | |
