-;;; google-c-style.el --- Google's C/C++ style for c-mode

-;;; Commentary:
-
-;; Provides the google C/C++ coding style. You may wish to add
-;; `google-set-c-style' to your `c-mode-common-hook' after requiring this
-;; file. For example:
-;;
-;;    (add-hook 'c-mode-common-hook 'google-set-c-style)
-;;
-;; If you want the RETURN key to go to the next line and space over
-;; to the right place, add this to your .emacs right after the load-file:
-;;
-;;    (add-hook 'c-mode-common-hook 'google-make-newline-indent)
-
-;;; Code:
-
-;; For some reason 1) c-backward-syntactic-ws is a macro and 2)  under Emacs 22
-;; bytecode cannot call (unexpanded) macros at run time:
-(eval-when-compile (require 'cc-defs))
-
-;; Wrapper function needed for Emacs 21 and XEmacs (Emacs 22 offers the more
-;; elegant solution of composing a list of lineup functions or quantities with
-;; operators such as "add")

-This implements title \"Function Declarations and Definitions\"
-of the Google C++ Style Guide for the case where the previous
-line ends with an open parenthese.
-
-\"Current C expression\", as per the Google Style Guide and as
-clarified by subsequent discussions, means the whole expression
-regardless of the number of nested parentheses, but excluding
-non-expression material such as \"if(\" and \"for(\" control
-structures.

-Suitable for inclusion in `c-offsets-alist'."
