+# Generate changelog. The version/name of the generated packages are based on this.
+#
+# Resulting packages are formatted as;
+#
+# - name of the package (e.g., "docker-ce")
+# - version (e.g., "23.0.0~beta.0")
+# - pkgRevision (usually "-0", see above), which allows updating packages with
+#   packaging-only changes (without a corresponding release of the software
+#   that's packaged).
+# - distro (e.g., "ubuntu")
+# - VERSION_ID (e.g. "22.04" or "11") this must be "sortable" to make sure that
+#   packages are upgraded when upgrading to a newer distro version ("codename"
+#   cannot be used for this, as they're not sorted)
+# - SUITE ("codename"), e.g. "jammy" or "bullseye". This is mostly for convenience,
+#   because some places refer to distro versions by codename, others by version.
+#   we prefix the codename with a tilde (~), which effectively excludes it from
+#   version comparison.
+#
+# Note that while the `${EPOCH}${EPOCH_SEP}` is part of the version, it is not
+# included in the package's *filename*. (And if you're wondering: we needed the
+# EPOCH because of our use of CalVer, which made version comparing not work in
+# some cases).
+#
+# Examples:
+#
+# docker-ce_23.0.0~beta.0-1~debian.11~bullseye_amd64.deb
+# docker-ce_23.0.0~beta.0-1~ubuntu.22.04~jammy_amd64.deb
