ClickOnce deployment with NAant script?

Hi!
I have a c# application for which I want to make an automated ClickOnce Deployment script.
I'm doing it with NAant together with a build file. It works fine, but I wonder if the way I've done it is the right way to go?!
Below you can see the relevant parts of the build file.
I especially wonder if it is correct to use the "New Application" and "New Deployment" switch should be used every time an update is done?!
Can anyone give me some input?

<!-- Copy all the files to the deploy folder -->
<echo message="Copying Application files from ${build.dir} to $${Deployment.dir}\${publish.version}." />
<delete dir="${Deployment.dir}\${publish.version}" failonerror="false" />
<mkdir dir="${Deployment.dir}\${publish.version}" />
<copy todir="${Deployment.dir}\${publish.version}" overwrite="true" includeemptydirs="true" >
    <fileset basedir="${build.dir}">
        <includes name="**" />
    </fileset>
</copy>
