;;; plplot-c-style.el --- PLplot's C/C++ style for c-mode
;; Keywords: c, tools

;;; Commentary:
;; Provides the PLplot C/C++ coding style. You may wish to add
;; `plplot-set-c-style' to your `c-mode-common-hook' after requiring this
;; file. For example:
;;
;; (add-hook 'c-mode-common-hook 'plplot-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 'plplot-make-newline-indent)
