+;; Author:     2007 William Baxter

+;;
+;; cc-mode version 5.30 or greater is required.
+;; You can check your cc-mode with the command M-x c-version.
+;; You can get the latest version of cc-mode at http://cc-mode.sourceforge.net
+;;
+;; Commentary:
+;;   This mode supports most of D's syntax, including nested /+ +/
+;;   comments and backquote `string literals`.
+;;   
+;;   This mode has been dubbed "2.0" because it is a complete rewrite
+;;   from scratch.  The previous d-mode was based on cc-mode 5.28 or
+;;   so.  This version is based on the cc-mode 5.30 derived mode
+;;   example by Martin Stjernholm, 2002.
+;;
+;;
+;; TODO:
+;;   * I tried making "with" "version" and "extern" be their own
+;;     c-other-block-decl-kwds.  Which is supposed to mean that you
+;;     can control the indentation on the block following them
+;;     individually.  It didn't seem to work right though.
+;;
+;; History:
+;;   * 2010-11-13 -- 2.0.5-SNAPSHOT add immutable as a keyword.
+;;   * 2008 February - 2.0.4 - fixed "else static if" indentation problem, 
+;;      and also a problem with "debug if()" indentation.
+;;      Some D2 additions (invariant as type modifier etc).
+;;   * 2007 April - 2.0.3 - new 'ref' and 'macro' keywords.
+;;   * 2007 March 3 - Verision 2.0.1 - bugfixes for emacs 21 and
+;;      user-installed cc-mode.  Byte compilation was failing.
+;;   * 2007 March 3 - Release of 2.0.0 version
