This looks super nice. Sometimes I need to answer how long a
commit/series has been in next to either take it out of the PR or to at
least have a comment to Linus.
I see that I can use the script like `histo.sh /PATH/TO/DB COMMIT-ID`,
which is exactly what I would expect.

Is the idea to run the scripts from
https://git.kernel.org/pub/scm/linux/kernel/git/sashal/next-analysis.git
or to populate ones own DB in linux-next and then run histo?

thx

Best
