* Images (whatever their format : PNG, SVG, EPS...) generated by running PlantUML

* textual description in PlantUML language). Those images are not covered by

* The generated images can then be used without any reference to the GPL v2 license.
* It is not even necessary to stipulate that they have been generated with PlantUML,
* although this will be appreciated by the PlantUML team.
*
* There is an exception : if the textual description in PlantUML language is also covered
* by any license, then the generated images are logically covered
* by the very same license.
