From 5ee9fb39bf41ab8f7c074becc15dcf3a3cb15449 Mon Sep 17 00:00:00 2001

Subject: [PATCH] log: don't automatically setup gbp-specific logger

This makes it nicer to use gbp.* modules (e.g. gbp.git) in other
software projects which may have their own logging setup. Now, importing
gbp.* modules won't force-setup logging.
