- <description><p>Back in September, I blogged about
-<a href="http://people.skolelinux.org/pere/blog/The_life_and_death_of_a_laptop_battery.html">the
-system I wrote to collect statistics about my laptop battery</a>, and
-how it showed the decay and death of this battery (now replaced). I
-created a simple deb package to handle the collection and graphing,
-but did not want to upload it to Debian as there were already
-<a href="https://tracker.debian.org/pkg/battery-stats">a battery-stats
-package in Debian</a> that should do the same thing, and I did not see
-a point of uploading a competing package when battery-stats could be
-fixed instead. I reported a few bugs about its non-function, and
-hoped someone would step in and fix it. But no-one did.</p>
-
-<p>I got tired of waiting a few days ago, and took matters in my own
-hands. The end result is that I am now the new upstream developer of
-battery stats (<a href="https://github.com/petterreinholdtsen/battery-stats">available from github</a>) and part of the team maintaining
-battery-stats in Debian, and the package in Debian unstable is finally
-able to collect battery status using the <tt>/sys/class/power_supply/</tt>
-information provided by the Linux kernel. If you install the
-battery-stats package from unstable now, you will be able to get a
-graph of the current battery fill level, to get some idea about the
-status of the battery. The source package build and work just fine in
-Debian testing and stable (and probably oldstable too, but I have not
-tested). The default graph you get for that system look like this:</p>

-
-<p>My plans for the future is to merge my old scripts into the
-battery-stats package, as my old scripts collected a lot more details
-about the battery. The scripts are merged into the upstream
-battery-stats git repository already, but I am not convinced they work
-yet, as I changed a lot of paths along the way. Will have to test a
-bit more before I make a new release.</p>
-
-<p>I will also consider changing the file format slightly, as I
-suspect the way I combine several values into one field might make it
-impossible to know the type of the value when using it for processing
-and graphing.</p>
-
-<p>If you would like I would like to keep an close eye on your laptop
-battery, check out the battery-stats package in
-<a href="https://tracker.debian.org/pkg/battery-stats">Debian</a> and
-on
-<a href="https://github.com/petterreinholdtsen/battery-stats">github</a>.
-I would love some help to improve the system further.</p>
