duc - 1.4.5-1+b2 main

Duc maintains a database of accumulated sizes of directories of the file
system, and allows you to query this database with some tools, or create
fancy graphs showing you where your bytes are.
.
Duc comes with console utilities, ncursesw and X11 user interfaces and a
CGI wrapper for disk usage querying and visualisation.
.
Duc is designed to scale to huge filesystems: it will index and display
hundreds of millions of files on petabytes of storage without problems.
