Autoinsert

        Hello to every body.

	I'm starting with the skeletons and autoinsert. Skeletons and abbrevs 
work fine, but the autoinsert doesn't expand the tag.
        In my .emacs file I have the following lines about autoinsert:

(require 'autoinsert)
(add-hook 'find-file-hook 'auto-insert)
(define-auto-insert "\\.\\(H\\|hh\\|hxx\\|hpp\\)\\'" "cxx-header.hh")

        And the cxx-header.hh file is like this:

#ifndef __%B_%E__
#define __%B_%E__

class %@
{

};

#endif

	And nothing is expanded. Someone can help me? (I don't want to use 
skeletons here)


        A lot of Thanks
