| <h2 id="filter">Filter</h2> |
| <h3>Description</h3> |
| <p>Sets a token filter for this project or reads a properties file as multiple token filter |
| definitions and sets them. Token filters are used by all tasks that perform file copying operations |
| through the Project commodity methods. See the |
| warning <a href="../using.html#filters"><em>here</em></a> before using.</p> |
| <p>The task uses <q>@</q> as token separator. Token strings cannot contain separator characters; |
| incorrect tokens are ignored.</p> |
| |

| <tr> |
| <td>token</td> |
