```
 * Taligent is a registered trademark of Taligent, Inc.
 *
 * Permission to use, copy, modify, and distribute this software
 * and its documentation for NON-COMMERCIAL purposes and without

which is not compatible with the GNU General Public License version 2. Following existing conventions, prepend this text:

```

 * License version 2 only, as published by the Free Software Foundation.
 * However, the following notice accompanied the original version of this
