umlet - 15.1+ds-1 main

UMLet is a UML tool aimed at providing a fast way of drawing
UML diagrams. UML elements are modified using text input instead
of pop-up dialogs. Elements can be modified and used as
templates; this way, users can easily tailor UMLet to their
modeling needs. UMLet supports a variety of UML diagram types:
class diagrams, use case diagrams, sequence diagrams, state
diagrams, deployment diagrams, activity diagrams, etc.
.
UMLet can only be used for drawing UML diagrams, it does not
support code export or the XMI format. UMLet allows one to export
diagrams as images or PDF.
