Does anyone have python code which digests pgbench -r output?

All:

Does anyone have python code which parses pgbench -r output for
statistical analysis?  I dug through pgbench-tools, but its reading of
pgbench results isn't easily separable from the rest.

I'll write a lib, but if someone already has one, it would save me some
time in developing a new public benchmark.
