Revision:	1.5
Committed:	Mon Mar 18 13:46:12 2002 UTC (22 years, 7 months ago) by pajs
Content type:	text/plain
Branch:	MAIN
Changes since 1.4:	+95 -10 lines
Log Message:	Solaris top replacement now as functional as the linux one, although the way of getting the process stats is horrible and will be re-written at some point. Has the same "features" as top.. Eg Swap Free actually also include free memory as that is what top (strangly imo) says.
