duv Visual Disk Usage 2.0

duv visual disk usage draws an interactive visualization of disk usage, with display area proportional to disk space.
The map may be based on directory hierarchy, uid of owner, file extension (.c, .mp3, etc.), or number of days since last access or modification. As you move the pointer across the display, duv annotates the filename and size.
As you enter commands via keyboard or button clicks, duv navigates the hierarchy (real or pseudo) and updates the display. Duv can print, copy, or clip the pathname, sort by size, and print a textual list or encapsulated PostScript rendering of the current display.
Enhancements:
- duv is now distributed with source code and licensed under GNU General Public License, version 2.
- New code features include options for dealing with bad hardlink counts on DVD/CD and not crossing mount points when analyzing space (such as on a root filesystem).
