The target for master should stay as is, but there should also be a target for basic remaster usage now. It would possibly also be nice to include a basic remaster example in this repo which can be pulled in as part of the setup task

The relevant target should look something like this

  <target name="remaster"
      description="Run a remaster simulation: ant remaster -DbeastXMl=sim.xml">
    <exec executable="sh">
      <arg path="lib/beast/bin/beast" />
      <arg line="-seed 1" />
      <arg line="-overwrite" />
      <arg path="${beastXML}" />
    </exec>
  </target>
