+Development package builds
+**************************

+To ease the development and testing of local packaging changes,
+development-quality DEB or RPM packages can be built with one of the following
+scripts on a build host which already has all system build dependencies
+installed:
+
+.. code-block:: bash
+
+   ./packages/brpm --distro=redhat  # or --distro=suse to build an RPM
+   ./packages/bddeb -d  # to build a DEB
+
+OR if LXD is present, the full package build can be run in a container:
+
+.. code-block:: bash
+
+   ./tools/run-container ubuntu-daily:plucky --package --keep
+   ./tools/run-container rockylinux/9 --package --keep
+
+
+.. note::
+
+   meson support has not yet been added to the BSDs in :file:`tools/build-on-*bsd` or :file:`meson.build`.
