| 28 | ;; Org-Babel support for evaluating maxima entries. | |
| 29 | ;; | |
| 30 | ;; This differs from most standard languages in that | |
| 31 | ;; | |
| 32 | ;; 1) there is no such thing as a "session" in maxima | |
| 33 | ;; | |
| 34 | ;; 2) we are generally only going to return output from maxima | |
| 35 | ;; | |
| 36 | ;; 3) we are adding the "cmdline" header argument | |
| 37 | ;; | |
| 38 | ;; 4) there are no variables | |
