-xfce4-screenshooter currently supports three different levels of debugging support,
-which can be setup using the configure flag `--enable-debug` (check the output
-of `configure --help`):
+From release tarball:
 
-| Argument  | Description |
-| -------   | ----------- |
-|  `yes`    | This is the default for Git snapshot builds. It adds all kinds of checks to the code, and is therefore likely to run slower. Use this for development of xfce4-screenshooter and locating bugs in xfce4-screenshooter. |
-| `minimum` | This is the default for release builds. **This is the recommended behaviour.** |
-| `no`      | Disables all sanity checks. Don't use this unless you know exactly what you do. |
