Subject: [PATCH]     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.
