rafaelsoaresbr [1] filed a deletion request for umlet [2]:

This is a split package:

The package umlet-standalone (14.2) is already in [Community]: umlet
(14.1.1). Delete it!

The package umlet-eclipse-plugin (14.2) could be merged with eclipse-
umlet (13.3). The first is built from source while the second is not.
