Revision: 1.8
Committed: Sun Mar 30 23:21:55 2003 UTC (21 years, 7 months ago) by pajs
Content type: text/plain
Branch: MAIN
Changes since 1.7: +87 -5 lines
Log Message: 
Now allows the user to choose whats being displayed. Currently only allows
the toggling of what we display by default, but its minor work adding the
others. I think may need to change the display structure, as i dont think
i will end up implementing like my original plan was.

Currently it does
'm' (memory)
's' (swap)
'l' (load)
'd' (disk_io)
'n' (network)
'p' (paging)
'c' (cpu)
