I'm currently playing with Ant to do some auto branding work. I modified default build.xml and setup my own target. What I hope to ask is that is there a way in Ant Script that could automatic renaming the apk file just build with the certain name? 

I currently has this Ant target setup in my build.xml:

```
<target name="release-brandA"
            depends="default, -set-release-mode, -release-obfuscation-check, -package, -post-package, -release-prompt-for-password, -release-nosign, -release-sign, -post-build"
            description="Builds the application in release mode for brandA.">
    <delete dir="${res}" />
    <copydir dest="${res}" src="${branding}/brandA" forceoverwrite="ture" />
    <replaceregexp flags="g" byline="false">
        <regexp pattern="import com.arthur.android(.*).R;"/>
        <substitution expression="import com.arthur.android.brandA.R;"/>
        <fileset dir="src" includes="**/*.java" />
    </replaceregexp>
    <replaceregexp flags="g" byline="false">
        <regexp pattern="package=&quot;com.arthur.android(.*)&quot;" />
        <substitution expression="package=&quot;com.arthur.android.brandA&quot;" />
        <fileset dir="" includes="AndroidManifest.xml" />
    </replaceregexp>
</target>

```

Is there a way that I could add some more task, to let the output file just be like brandA.apk?

Thank you!
