From 68fdc83a89e27959c0a5189e3a2ded387555a77d Mon Sep 17 00:00:00 2001
From: Ian Jackson <ijackson@chiark.greenend.org.uk>
Date: Wed, 29 Dec 2021 17:04:34 +0000
Subject: [PATCH] overview diagram: Build as pdf, with a sensible page layout,
 rather than ps

Use SOURCE_DATE_EPOCH to squash the nonreproducible timestamp,
rather than seddery to delete it.
