From 532c1171316bd69c3e0140ba43269db61cc9427f Mon Sep 17 00:00:00 2001
From: Chenxiong Qi <cqi@redhat.com>
Date: Jun 06 2018 07:21:02 +0000
Subject: Add new command for creating override in Bodhi


To create a buildroot override, run inside a package repo:

    fedpkg override create --duration 5

It also accepts a specified build:

    fedpkg override create --duration 5 rpkg-1.54-2.fc27

Fixes #92
