Hello Ricardo,

I would suggest to extend a bit the scope of this idea. What about
creating an etc/tutors.scm file as the one attached.

This way people would run something like:

--8<---------------cut here---------------start------------->8---
git send-email $(get-tutors.scm HEAD^^) *.patches
--8<---------------cut here---------------end--------------->8---

The get-tutors.scm command would take a git reference as argument. From
this git reference the list of edited files would be extracted. Once
matched with the modules field of tutors.scm, the ML & tutors that
should be CC'ed would be returned.

For the previous example, if the patches are modifying (gnu packages
bioconductor), the command would be:

--8<---------------cut here---------------start------------->8---
git send-email --to guix-patches@gnu.org --cc guix-r-patches@gnu.org
--cc rekado@elephly.net --cc zimoun.toutoune@gmail.com *.patches
--8<---------------cut here---------------end--------------->8---

People could subscribe to the relevant ML if they want to follow
specific subjects. If someone wants to become a tutor, a patch could be
sent against the tutors.scm file.

Being listed in the tutors.scm file would imply some duties, such as
trying to review part of the traffic for the tutored parts.

We could then turn this tutors.scm file into a website page,
transforming the tutors SEXP into an HTML table.

WDYT?

Thanks,

Mathieu
