/**
* Ant task to run Mauve test-suite.
* <p>Before asking questions; always refer to the <a href="http://jakarta.apache.org/ant/manual/index.html">ant manual</a> first.</p>
<p>Test classes are passed as child fileset tags, typically you simply pass the build
dir for the project</p>

<td align="center" valign="top">No</td>

<tr>
<td valign="top">verbose</td>
<td valign="top">Lets the test suite be more verbose; also showing passed-tests for example</td>

<td valign="top">haltonfailure</td>
<td valign="top">make the testrun halt as soon as a failure is failed (see also failonerror)</td>

<td valign="top">srcdir</td>
<td valign="top">provide the sources directory allowing the parsing of a "Tags:" comment in the header of the file. If the testJDK or testJDBC are also supplied then tests that have tags specifying that their API comatibility are incompatible with the testJDK/testJDBC version will be skipped.</td>

<tr>
<td valign="top">testJDK</td>
<td valign="top">The version of the JDK you are running/simulating. Only tests that are compatible with this version will be run.</td>
