Note that newer versions of plantuml supports additional diagram types, so
diagrams may need to use:
  @startuml   .. @enduml
  @startsalt  .. @endsalt
  @startdot   .. @enddot
  @startditaa .. @endditaa
  @startgantt .. @endgantt

It is expected that support for new diagram types will use keywords
starting with "@start" and "@end" as delimiters. See "Generalisation" at
http://plantuml.com/ditaa for more details.
