# Script to monitor disk usage.
#
#   DESCRIPTION
#   ===========
#     This will report back the sizes of the filesystems currently
#     mounted.  All measurements are reported in percents, not in actual
#     512KB pages.  It uses /usr/bin/df.
#     
#   RESCTRICTIONS
#   =============
#     Unless you've restricted who can use /usr/bin/df then there are none.
#
# Parameters understood:
#
# 	config   (required)
# 	autoconf (optional - used by munin-config)
#
# Magic markers (optional - used by munin-config and installation
# scripts):
#
#%# family=contrib
#%# capabilities=autoconf
