Usage

First, you may need to specify plantuml command in your conf.py:

plantuml = ['java', '-jar', '/path/to/plantuml.jar']

Instead, you can install a wrapper script in your PATH:

% cat <<EOT > /usr/local/bin/plantuml
#!/bin/sh -e
java -jar /path/to/plantuml.jar "$@"
EOT
% chmod +x /usr/local/bin/plantuml

Then, write PlantUML text under .. uml:: directive:

.. uml::

   Alice -> Bob: Hi!
   Alice <- Bob: How are you?
