Inno Setup compile directory
===

This is the first time I've used Inno Setup. I am including Inno Setup in an ANT script:

    <target name="generate-installer-exe" depends="generate-exe">
      <exec executable="C:/Program Files (x86)/Inno Setup 5/ISCC.exe">
        <arg value="${etc.dir}/innoSetup_config.iss"/>
        <arg value="/dMySourcePath=${deployment.dir}"/>
      </exec>
    </target> 

It creates the Output and setup.exe in the `${etc.dir}` since that is where my .iss file is, but i want it to compile to the `${deployment.dir}`.  Is there anyway to dynamically change the compile directory by passing an argument or do I need to move the files via ANT?
