summary: Free UML Tool for Fast UML Diagrams 
description: |
  UMLet is a free, open-source UML tool with a simple user interface: draw UML diagrams fast,
  build 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. 

  This is a community build based on the standalone executable without support by the original 
  authors.
