I've attached a patch which adds Performance Data output, and also adds
the 's' flag to the usage output.
However, as you can see from what I've pasted below, only 'used' works
on my RH9 system. Free and Swap are borked.

And, just to be sure that it was not the changes that I've made which
broke the plugin:
