+
+;; First comes a setup that is ideal when you are only working with curl. Just
+;; select the next few lines, paste it into your .emacs and change the path to
+;; the tools folder. (If you are using more than one style. Look further down
+;; the this file.)
+

+(add-hook 'c-mode-common-hook 'curl-c-mode-common-hook)
+
+;; If you are using more than one style in maybe more than one project the
+;; example below might help out. It uses a predicate hook pair to select the
+;; right hook to use.
+
+(defvar my-style-selective-mode-hook nil
+  "Holds a list of predicate and hooks pairs. (list (PREDICATE . HOOK)
+...) It is used by my-mode-selective-mood-hook-function for choosing
+the right hook to run.")

+  "Run each PREDICATE in `my-style-selective-mode-hook' to see if the 
+HOOK in the pair should be executed. If the PREDICATE evaluate to non

+(add-hook 'c-mode-common-hook 'my-style-selective-mode-hook-function)
