 # rear contains only bash scripts plus documentation so that on first glance it could be "BuildArch: noarch"
 # but actually it is not "noarch" because it only works on those architectures that are explicitly supported.
 # Of course the rear bash scripts can be installed on any architecture just as any binaries can be installed on any architecture.
