<h2><a name="copy">Copy</a></h2>
<h3>Description</h3>
<p>Copies a file or Fileset to a new file or directory.  Files are
only copied if the source file is newer than the destination file,
or when the destination file does not exist.  However, you can explicitly 
overwrite files with the <var>overwrite</var> attribute.</p>
<p><a href="../CoreTypes/fileset.html">FileSet</a>s are used to select files to copy.  
To use a fileset, the <var>todir</var> attribute must be set.</p>
