| * Determines profile activation based on the existence/absence of some file. |
| * File name interpolation support is limited to <code>${basedir}</code> (since Maven 3, |
| * see <a href="https://issues.apache.org/jira/browse/MNG-2363">MNG-2363</a>), |
| * System properties and request properties. |
| * <code>${project.basedir}</code> is intentionally not supported as this form would suggest that other |
| * <code>${project.*}</code> expressions can be used, which is however beyond the design. |
