Tasks are made available to the CIM framework by adding an XML snippet to any /plugin_name/tasks.xml file as shown in the example:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE tasks SYSTEM "http://www.atg.com/dtds/task_1_0.dtd">

<task id="DeleteFileTask" class="atg.cim.task.DemoTask">
   <property name="fileName">
      <input type="text">
         <label>Enter a file name : </label>
       </input>
   </property>
</task>

You can now refer to the DeleteFileTask in your wizards.xml file.
