+xdiskusage is a user-friendly program to show you what is using up all
+your disk space. It is based on the design of xdu written by Phillip
+C. Dykstra <dykstra at ieee dot org>. Changes have been made so it 
+runs "du" for you, and can display the free space left on the disk,
+and produce a PostScript version of the display.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
