delete cvs dirs

[Ciramella, EJ]

I would like to delete all the CVS directories in the build tree.

Here is my target:
  <target name="cleanupcvs">
   <delete defaultexcludes="false">
     <fileset dir=".">
      <include name="**/CVS/**"/>
    </fileset>
   </delete>
  </target>

Here is the message I get and nothing gets deleted:

[delete] DEPRECATED - Use of the implicit FileSet is deprecated.  Use a
nested fileset element instead.


What am I doing wrong?
