    this is used as a last step in jenkins automated builds.

    see examples on how to generate an xml file containing code metrics information.

    Call this after a build (see goodies/builder/quichSelfTest.st) and import from jenkins.

    Currently supported formats are:

        #xml_xradar      - an xradar metrics compatible format

                         see http://xradar.sourceforge.net/

                         (see http://grepcode.com/file/repo1.maven.org/maven2/net.sf.xradar/xradar/1.1.2/dtds/metrics.dtd)

        #xml_metrics     defaults to xradar

    By default, the following metrics are generated:

        per method: 

                none

        per class: 

                LOC (lines of code)

        per package: 

                LOC (lines of code)

                NOC (number of classes)
