# $Id$
#
# possible output formats:
# (blanks around tabs only for better reading)
# 1) Name \t Value displays Name and Value
# 2) Name \t Value1 \t Value2 displays Name, Value1 and Value2
# 3) Name \t total used displays an additional progress bar (percentage) after the values
# 4) s \t Name \t ... defines a static value, this line is only requested during the first cycle
#
# special keywords (they are replaced by the plugin with the actual value):
# CPU% CPU usage in percent
