- /**
- * Sets a property to the base name of a specified file, optionally minus a
- * 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.
