openssl/doc/c-indentation.el

; This Emacs Lisp file defines a C indentation style that closely
; follows most aspects of the one that is used throughout SSLeay,
; and hence in OpenSSL.
; 
; This definition is for the "CC mode" package, which is the default
; mode for editing C source files in Emacs 20, not for the older
; c-mode.el (which was the default in less recent releaes of Emacs 19).
;
; Copy the definition in your .emacs file or use M-x eval-buffer.
; To activate this indentation style, visit a C file, type
; M-x c-set-style <RET> (or C-c . for short), and enter "eay".
; To toggle the auto-newline feature of CC mode, type C-c C-a.
;
; Apparently statement blocks that are not introduced by a statement
; such as "if" and that are not the body of a function cannot
; be handled too well by CC mode with this indentation style,
; so you have to indent them manually (you can use C-q tab).
; 
; For suggesting improvements, please send e-mail to bodo@openssl.org.
