Ant uses this technique for handling optional stuff
- set a property if needed jars are there: <available>
- include the classes only if that property is set: <include if|unless>

So you could the copying stuff with

    <!-- copy usual things -->
    <mkdir dir=3D"${to.dir}"/>
    <copy todir=3D"${to.dir}"><fileset dir=3D"${src.dir}"/></copy>
   =20
    <!-- copy special file from another directory -->
    <copy todir=3D"${to.dir}">
        <fileset dir=3D".">
            <include name=3D"stage.only" if=3D"stage"/>
        </fileset>
    </copy>

But dont forget: as the same as in target=B4s if/unless clause
here the same is checked: WHETHER that property is set, not to which
value!

Usual copy
    ant

Stage copy
    ant -Dstage=3Dtrue

Another stage copy
    ant -Dstage=3Dfalse
