+      UMLet is a free, open-source UML tool with a simple user interface:
+      draw UML diagrams fast, produce sequence and activity diagrams from
+      plain text, export diagrams to eps, pdf, jpg, svg, and clipboard,
+      share diagrams using Eclipse, and create new, custom UML elements.
+      UMLet runs stand-alone or as Eclipse plug-in on Windows, OS X and
+      Linux.
