Dear packager,
instead of spending a minute on a nice reply here on the list, the FPC
ruled quickly on something related today because a ticket has been opened
in parallel. You may continue to store all these development-only files in
the base package instead of building only a -devel package. Now pray that
the packaged software will never add a library. Because then you would
need to change any BuildRequires for your package in other spec files.
