Wordpress wp_head() crap

Question

I know, wp_head() is important, but it inject so much crap into the header, i like to get it out... and just add manually the 2-3 line of code i need..

BUT, and there is always a but, i need the wordpress auto-generated code for :

<meta name="description" content="" />
<meta name="keywords" content="" />
<link rel='canonical' href='http://jlecologia.com/cms/' /> (why not!)
and
<meta http-equiv="Content-Language" content="fr-FR" />

How i can ask for the generation of that... ???? something like : bloginfo('name') will be fine for me

Thanks

You can remove some of the header stuff with the following.

// remove unncessary header info
function remove_header_info() {
    remove_action('wp_head', 'rsd_link');
    remove_action('wp_head', 'wlwmanifest_link');
    remove_action('wp_head', 'wp_generator');
    remove_action('wp_head', 'start_post_rel_link');
    remove_action('wp_head', 'index_rel_link');
    remove_action('wp_head', 'adjacent_posts_rel_link');
}
add_action('init', 'remove_header_info');

The default installation does not include stuff like meta keywords, so that is either a theme or plugin that you are using.

Have a look here: http://codex.wordpress.org/Plugin_API/Action_Reference/wp_head

Essentially you need to add an action for the wp_head hook, and (probably) remove the other actions that have been associated with the wp_head hook.
