;;; Commentary:
;; SiSU (https://www.sisudoc.org/) is a document structuring and
;; publishing framework. This package provides an Emacs major mode
;; for SiSU markup, as used by the spine parser (in D) which has a different
;; header (based on yaml) from the original sisu parser (in Ruby) which has
;; bespoke headers.
;; When this package is installed, files ending in ".sst" are automatically
;; associated with sisu-spine-mode. If a file doesn't have a
;; .sst extension, add a first line:
;; # -*- sisuSpine -*-
;; The documentation for the "Structure Of The Hierarchy Text" can be
;; found in the sisustring for the sisu-spine-mode function.
