Recorded build and packaging recipes

These recipes preserve the commands and dependency inputs used for the released
applications. They retain historical staging paths. Review and adapt those paths
to a separate build directory before running them; start with BUILDING.txt.
They are not deployment commands for an existing installation.

Native package recipes require the matching compiled payloads and source archives
as inputs, plus dpkg-deb/rpmbuild or FreeBSD pkg. They preserve the original
package metadata; see LICENSING.txt (NXX) or LICENSE (Support) for licence terms.
