[Eug-lug] Looking at the 'free' command

[Ben Barrett]

Bob, thanks for the gkrellm plug -- I am an old fan of it.
However, I'd never used the daemon/remote; only ever remote-X via ssh.
It is such a small app, do you think there is a substantial difference
between running the daemon
with a local gui client vs. tunneled/remote-X?

PS - the krells are very configurable, and I always changed the defaults --
I'd invert the charts for read-vs-write, in-vs-out, etc,
to make maximum data immediately readable.  Anecdote:  I was so impressed
when I first brought it up remotely, I was using my first laptop
and had never seen more than 1 CPU krell at once; this was on a UO system
which was just beginning to have some gnome goodies, over 5 years ago...
and those transparent themes are nice candy :)
