## Notice: Given that you include this file verbatim into your own |

## source tree, you are justified in saying that it remains separate |
| 31 |
|

## from your package, and that this way you are simply just using GNU |
| 32 |
|
|
## shtool. So, in this situation, there is no requirement that your |
| 33 |
|
|
## package itself is licensed under the GNU General Public License in |
| 34 |
|
|
## order to take advantage of GNU shtool. |
