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