+; 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 is the default in 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.
+; The style defined below does not indent them at all.
+; To insert tabs manually, prefix them with ^Q (the "quoted-insert"
+; command of Emacs).  If you know a solution to this problem
+; or find other problems with this indentation style definition,
+; please send e-mail to bodo@openssl.org.
