% PlantUML in a Beamer presentation (#11).
%
% The only requirement is that the frame is declared [fragile]: the plantuml
% environment captures its body verbatim, and Beamer needs [fragile] for frames
% that contain verbatim material. Without it you get errors like
% "Paragraph ended before \beamer@doframe was complete".
