# Show top disk space users in current directory,

# License: LGPLv2
# Author: P@draigBrady.com
#Design decisions:
# 1. Don't show tree as can only view one level at a time
# You could use a treemap, where you can see large files
# anywhere on disk. However the size is relative to all
# files on disk and not current level, which IMHO is usually
# what's required and easier to navigate.
# 2. Note I rerun du when browsing into directories. I.E.
# I don't cache the tree locally. This is because the
# kernel will do this anyway, so why duplicate code & data?
#TODO:
# hardlink doesn't have to be in the same directory at all,
# but since only showing one, then flag warning saying more
# than 1 link => do exhaustive search to del all? or just
# redisplay next name if hardlink in current directory.
#
# Set (background?) colour like batt_stat?
#
# ' in filenames will cause probs
