An Ant task for instrumenting persistent classes in order to enable field-level interception using Javassist.

In order to use this task, typically you would define a a taskdef similiar to:

<taskdef name="instrument" classname="org.hibernate.tool.instrument.javassist.InstrumentTask">
    <classpath refid="lib.class.path"/>
</taskdef>

where lib.class.path is an ANT path reference containing all the required Hibernate and Javassist libraries.

And then use it like:

<instrument verbose="true">
    <fileset dir="${testclasses.dir}/org/hibernate/test">
        <include name="yadda/yadda/**"/>
        ...
    </fileset>
</instrument>

where the nested ANT fileset includes the class you would like to have instrumented.

Optionally you can chose to enable "Extended Instrumentation" if desired by specifying the extended attriubute on the task:

<instrument verbose="true" extended="true">
    ...
</instrument>

See the Hibernate manual regarding this option.
