+# This file contains llgo's configuration for the buildbot-slave Juju charm.
+# 
+# The slave is deployed with the following command in a Juju environment:
+#     juju deploy cs:~axwalk/buildbot-slave --config buildslave-config.yaml
+#
+# The charm generates a random password on first run, in the file
+# /srv/buildbot/password. If the password is regenerated, it must
+# be updated in the buildbot master.
