Sample build file for use with ant-jmeter.jar
        See http://www.programmerplanet.org/pages/projects/jmeter-ant-task.php

To run a test and create the output report:
        ant -Dtest=script

To run a test only:
        ant -Dtest=script run

To run report on existing test output
        ant -Dtest=script report

The "script" parameter is the name of the script without the .jmx suffix.

Additional options:
        -Dshow-data=y - include response data in Failure Details
        -Dtestpath=xyz - path to test file(s) (default user.dir).
                         N.B. Ant interprets relative paths against the build file
        -Djmeter.home=.. - path to JMeter home directory (defaults to parent of this build file)
        -Dreport.title="My Report" - title for html report (default is 'Load Test Results')
