Figuring how to work with team-maintained packages on salsa

[Florian Weimer <fw@deneb.enyo.de>]

I want to add a few patches to this repository:

  <https://salsa.debian.org/glibc-team/glibc/>

Surely there must be some tool support to help with that?  I know how
to do it manually (perhaps even involving quilt).  Has every Debian
developer their own script for that?  (It's like this in RPM land …)
