All reports of source-only-upload-to-non-free-without-autobuild for the archive. The extended description of this tag is:
For licensing reasons packages from the non-free section are not built by the autobuilders by default, so this source-upload to "non-free" will result in the package never appearing in the archive.
Please either perform a regular binary upload or (after checking the license) add XS-Autobuild: yes into the header part of debian/control and get the package added to the "autobuild" whitelist.
Refer to Debian Developer's Reference section 5.10.5 (Marking non-free packages as auto-buildable) for details.
This tag has not been emitted in any package tested by Lintian.
