     1  The `uml` directory contains .uml files that are used as input to
     2  PlantUML (http://plantuml.com). PlantUML produces .png files which
     3  can then be displayed. The .png files illustrate the architecture
     4  of certain operations such as a bimodal PUT operation.

     6  Then do something like:
     7  
     8      # java -jar plantuml.jar read.uml
     9  
    10  This will produce a correspondingly named .png file you can display.
