  +<p>Deletes either a single file or

  +<p>It is possible to refine the set of files that are being deleted. This can be
  +done with the <i>includes</i>, <i>excludes</i> and <i>defaultexcludes</i>
  +attributes. With the <i>includes</i> attribute you specify the files you want
to
  +have included in the deletion process by using patterns. The <i>exclude</i>
attribute is used to specify
  +the files you want to have excluded from the deletion process. This is also done with patterns.
And
  +finally with the <i>defaultexcludes</i> attribute, you can specify whether
you
  +want to use default exclusions or not. See the section on <a
  +href="#directorybasedtasks">directory based tasks</a>, on how the
  +inclusion/exclusion of files works, and how to write patterns. The patterns are
  +relative to the <i>dir</i> directory.</p>
