Successor to dstat

Since Debian Unstable switched to Python 3.13, the dstat(1) tool has
started reporting warnings about ill-formed regexes in its code. So I
checked bugs.debian.org
<https://bugs.debian.org/cgi-bin/pkgreport.cgi?dist=unstable;package=dstat>,
and it turns out dstat has been pretty much an orphaned project for
some years now <https://github.com/dagwieers/dstat>. Seems like Red
Hat’s taking some of the code for their “Performance Co-Pilot” project
<https://pcp.io/> was seen by the principal developer as some kind of
last straw <https://news.ycombinator.com/item?id=19986646>.

Someone else has forked the original dstat project and is calling
their version “dool” <https://github.com/scottchiefbaker/dool>. But
PCP is already available as a whole bunch of Debian packages. So maybe
I might give that a try.
