Renders PlantUML diagrams for use with Pandoc as part of the compilation process.
This filter depends on an executable plantuml.jar, which can be acquired from
their homepage:
$ cabal install pandoc-plantuml-diagrams
$ wget http://sourceforge.net/projects/plantuml/files/plantuml.jar/download -O plantuml.jar
Declare code blocks in the source markdown like:
```{#fig:actors .uml caption="See this!!!"}
@startuml
Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response
Alice -> Bob: Another authentication Request
Alice <-- Bob: another authentication Response
@enduml
```
and then call pandoc with --filter=pandoc-plantuml-diagrams.
