;;; Clang-format emacs integration for use with C/Objective-C/C++.

;; A minimal .emacs would contain:

;; (load "<path-to-clang>/tools/clang-format/clang-format.el")
;; (global-set-key [C-M-tab] 'clang-format-region)
;;
;; Depending on your configuration and coding style, you might need to modify
;; 'style' and 'binary' below.
