- *AppImage example config*: this is old AppImage configuration,
basically unmaintained, but copied from the **other** example
config files which are CC0-1.0 as well.
- *Sample Linux distro*: The example Linux distro has a handful
of trivial files, a bogus `/etc/issue`, that kind of thing.
- The bash completions are GPL-3.0-or-later
- FreeBSD packaging information is BSD-2-Clause
- Add a script for building a Calamares AppImage file (this is
useful in *some* limited contexts, not a general way to distribute
Calamares since it's much more efficient to use installed libs).
- Add example config files for this AppImage build.
- Download the linuxdeploy tools if they are missing
- Document script flags some more
