;;; Commentary:
;; This package provides a few functions and variables that can help in
;; automating converting reST documents to HTML from within emacs. You could
;; use a makefile to do this, of use the compile command that this package
;; provides.
;; You can also bind a command to automate converting to HTML:
;; (defun user-rst-mode-hook ()
;; (local-set-key [(control c)(?9)] 'rst-html-compile))
;; (add-hook 'rst-mode-hook 'user-rst-mode-hook)
