# 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):
