From 8b8a99ba567314d5a83633a8ef73a5491976c67c Mon Sep 17 00:00:00 2001 From: Dylan Baker Date: Wed, 16 Oct 2019 11:32:49 -0700 Subject: [PATCH] bin/pick-ui: Add a new maintainer script for picking patches In the long term the goal of this script is to nearly completely automate the process of picking stable nominations, in a well tested way. In the short term the goal is to provide a better, faster UI to interact with stable nominations.
