At the moment i do:
<!-- Choose one of these: intermediate, beta, final -->
<property name="state" value="intermediate"/>
<target name="init"
depends="prepare,init-final,init-beta,init-intermediate">
</target>
<target name="prepare">
<property name="${state}" value="true"/>
<tstamp/>
</target>
<target name="init-final" if="final">
...
</target>
<target name="init-beta" if="beta">
...
</target>
<target name="init-intermediate">
...
</target>
