Hi Stan,

---

pcpfans(1) in src/src/python now has the beginnings of a system
statistics collector called pm-collectl.py (appended).   The python

Looked at this a little bit more on the weekend - there were a few places where
the default output didn't quite match up with collectl output for me, so pushed a
change to change that behaviour a little.  There was a few fields that looked like
they needed to be converted to KB, and inspection of the collectl source shows
they're using 1024 bytes-per-KB - so I've changed over a few places.

Oh, I meant to post the output difference for reference too, so you can see the changes ...
