rmic and base problem

[michael irion]

i'm slightly confused about the rmic base.

   <target name="rmic" depends="compile">
      <rmic  base="${build}" includes="**/*.class" verify="true"       
      classpath="{project.classpath}" />
   </target>

compiles the Remote classes and places them in the build tree.  this
seems to work correctly.  what i want to do is to compile the
Remote classes and place them in a seperate directory tree.  

is this possible, while still using the includes attribute?
