That tells you _all_ the packages.  It's not useful for actually
regenerating a configuration, because it's unaware of the difference
between manually (the ~M in my script) and automatically installed
packages.  So if I take that list and install it onto a new system,
everything is registered as "manually installed", and nothing ever gets
removed when it's no longer needed.
