Revision:	1.26
Committed:	Sat Mar 17 21:57:16 2001 UTC (23 years, 7 months ago) by pjm2
Branch:	MAIN
Changes since 1.25:	+5 -1 lines
Log Message:	Bar displays can now be called with the optional paramter of $arrange. If this is set to "swap", then the 'difference' is displayed. I.e. if we have the data available for free memory and total memory, then it will be possible to display a bar of used memory.
