magento remove admin menu item

Is it possible,开发者_如何学Python in magento, to remove a menu item in admin?

I have a new module and am pulling the reviews and ratings into a new section. I'm not opposed to leaving them also in the catalog section, but if its possible (and clean) I'd like to nip it out of there.

Add next lines to extension config.xml file:

<adminhtml>
   <menu>
      <catalog>
         <children>
            <reviews_ratings>
               <disabled>1</disabled>
            </reviews_ratings>
         </children>
      </catalog>
   </menu>
</adminhtml>

And clear the cache.
