  <description>
    This build file is designed to report the performance
    of ant from various releases.
    to use:
    * install ant-contrib.jar to ($ANT_HOME|$HOME/.ant)/lib
    * install beanshell jar and bsf jar
    * use unix (with bash) or install cygwin
    * set the env variables {whichever needs testing}
      ANT_HOME
      ANT_HOME_6_5 (the directory containing ant 1.6.5)
      ANT_HOME_6_4
      ANT_HOME_5_4
    
    * run ant
    For example:
       export ANT_HOME="c:/cygwin/home/me/svn/trunk/dist"
       export ANT_HOME_5_4="l:/apps/apache-ant-1.5.4"
       ant.bat

    TODO: more build files.
