| <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> |

| <p><b>Copy a single file</b></p> |
| <pre> |
| <copy file="myfile.txt" tofile="mycopy.txt"/> |
