+
+;;; Commentary:
+
+;; Installation:
+;;   - Put `protobuf-mode.el' in your Emacs load-path.
+;;   - Add this line to your .emacs file:
+;;       (require 'protobuf-mode)
+;;
+;; You can customize this mode just like any mode derived from CC Mode.  If
+;; you want to add customizations specific to protobuf-mode, you can use the
+;; `protobuf-mode-hook'. For example, the following would make protocol-mode
+;; use 2-space indentation:
+;;
+;;   (defconst my-protobuf-style
+;;     '((c-basic-offset . 2)
+;;       (indent-tabs-mode . nil)))
+;;
+;;   (add-hook 'protobuf-mode-hook
+;;     (lambda () (c-add-style "my-style" my-protobuf-style t)))
+;;
+;; Refer to the documentation of CC Mode for more information about
+;; customization details and how to use this mode.
+;;
+;; TODO:
+;;   - Make highlighting for enum values work properly.
+;;   - Fix the parser to recognize extensions as identifiers and not
+;;     as casts.
+;;   - Improve the parsing of option assignment lists. For example:
+;;       optional int32 foo = 1 [(my_field_option) = 4.5];
+;;   - Add support for fully-qualified identifiers (e.g., with a leading ".").
