+# Given a tar.gz, build a package for the current OS.
+#
+# Supports these packaging types:

+#   .deb (Debian, Ubuntu, etc) - requires dpkg-dev, debhelper
+#   .rpm (AlmaLinux, Rocky Linux, OpenSUSE etc) - requires rpmbuild

+# If the MAINTAINER environment variable is set, this is used as a GPG key

+# The packages built with this script are not "official", in that they are
+# not part of any Linux distribution and may not follow the distribution's
+# policies.  Use at your own risk.
