% Demonstrates a global PlantUML preamble (skinparam styling) applied to every
% diagram, so the styling need not be repeated in each diagram. See #5.
%
% Here the preamble is written inline with the plantumlpreamble environment;
% alternatively, \plantumlpreamblefile{<file>} points at a style file. The
% styling below turns the colorful default into a print-friendly black & white.
\documentclass{scrartcl}
\usepackage[output=png]{plantuml}

% Applies to all diagrams below. Omit @startuml/@enduml in the diagrams so the
% preamble also takes effect on the PlantUML server (it is prepended there).

skinparam backgroundColor white
