a. jester.cfg
b. mutations.cfg
c. ignorelist.cfg

  <target name="jester" depends="">
    <delete dir="${modifiedsrc}"/>
    <copy todir="${modifiedsrc}">
      <fileset dir="${src}">
        <exclude name="**/*Test.java"/>
        <exclude name="**/AllTests.java"/>
      </fileset>
    </copy>
    <java classpath="${classpath}" classname="jester.TestTester">
