 * PlantUML can occasionally display sponsored or advertising messages. Those

 * functional diagrams.

 *
 * 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).
