* PlantUML can occasionally display sponsored or advertising messages. Those
* messages are usually generated on welcome or error images and never on
* functional diagrams.
* See https://plantuml.com/professional if you want to remove them
*
* Images (whatever their format : PNG, SVG, EPS...) generated by running PlantUML
* are owned by the author of their corresponding sources code (that is, their
* textual description in PlantUML language). Those images are not covered by
* this BSD license.
*
* The generated images can then be used without any reference to the BSD 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.
*
* This is the IGY distribution (Install GraphViz by Yourself).
* You have to install GraphViz and to setup the GRAPHVIZ_DOT environment variable
* (see https://plantuml.com/graphviz-dot )
