| 28 | ;; This accepts a 'file' header argument which is the target of the | |
| 29 | ;; compiled sass. The default output type for sass evaluation is | |
| 30 | ;; either file (if a 'file' header argument was given) or scalar if no | |
| 31 | ;; such header argument was supplied. | |
| 32 | ;; | |
| 33 | ;; A 'cmdline' header argument can be supplied to pass arguments to | |
| 34 | ;; the sass command line. | |
