removing directories

[Josh Sugnet]

I am trying to recursively remove all of the classes directories from a directory
tree, but am not having much luck.  I am trying the following:

<delete>
     <fileset dir="test" includes="**/classes" />
 </delete>

I can get the above to remove all class files by changing the includes line to
"**/*.classes" , but I cant seem to get it work with directory names.  Any help or
pointers is appreciated.

thanks,
josh
