| /** |
| * Task to determine the basename of a specified file, optionally minus a |
| * specified suffix. |
| * |
| * This task can accept the following attributes: |
| * <ul> |
| * <li>file |
| * <li>property |
| * <li>suffix |
| * </ul> |
| * The <b>file</b> and <b>property</b> attributes are required. The |
| * <b>suffix</b> attribute can be specified either with or without |
| * the ".", and the result will be the same (ie., the |
| * returned file name will be minus the .suffix). |
| * <p> |
| * When this task executes, it will set the specified property to the |
| * value of the last element in the specified file. If file is a |
| * directory, the basename will be the last directory element. If file |
| * is a full-path filename, the basename will be the simple file name. |
| * If a suffix is specified, and the specified file ends in that suffix, |
| * the basename will be the simple file name without the suffix. |
