it was no longer maintained and is now made deprecated by sadf and its

SVG: Give actual canvas height
Add a comment at the end of SVG output that indicates the actual canvas
height.
The actual height is frequently different (i.e. smaller) than that
indicated in the header of the SVG output. This is because some
activities have pre-allocated entries that don't result in graphs being
drawn, or because option 'skipempty' has been used.
Remove memory statistics from sar (those displayed by sar -R, not
sar -r!) I have always considered those data displayed by sar as a
"mistake from my youth". They are not related to the speed of any
specific device (except maybe CPU, but there are other means to
measure CPU speed...), so displaying data per second is just irrelevant.
Cast values to (unsigned long long) before calling pval()
pval() function, used by sadf for its raw output format, assumes values
type is unsigned long long. So cast the values to that type before
calling this function.

sadf: Add new output format: raw (part 1)
Add a new output format to sadf to display statistics saved in a binary
data file in raw format. Counters values are displayed "as is", without
trying to calculate an average value over the elapsed time interval.
This is something I have selfishly wanted to have for a long time now,
mainly for debugging purpose.
This first patch adds all the necessary global functions, and implements
the raw format only for CPU and task creation/system switching
statistics.
When a newly registered device (network interface or disk) was
supernumerary (i.e. there was no slot left in the list to store it), it
would take the place of another device in the list. This other device
would also appear as new and its counters would jump as if starting from
zero. This patch fixes that.
