+// Lines below have the format format is "keyword=value,...".  A
+// package will be upgraded only if the values in its metadata match

+// keywords are wild cards.) The keywords originate from the Release
+// file, but several aliases are accepted.  The accepted keywords are:
+//   a,archive,suite (eg, "stable")

+//   l,label         (eg, "Debian", "Debian-Security")

+//     site          (eg, "http.debian.net")
+// The available values on the system are printed by the command
+// "apt-cache policy", and can be debugged by running
+// "unattended-upgrades -d" and looking at the log file.
+//
+// Within lines unattended-upgrades allows 2 macros whose values are
+// derived from /etc/debian_version:
