All reports of patch-system-but-no-source-readme for the archive. The extended description of this tag is:

This package build-depends on a patch system such as dpatch or quilt, but there is no debian/README.source file. This file is recommended for any package where dpkg-source -x does not result in the preferred form for making modifications to the package.

If you are using quilt and the package needs no other special handling instructions, you may want to add a debian/README.source referring to /usr/share/doc/quilt/README.source. Similarly, you can refer to /usr/share/doc/dpatch/README.source.gz for dpatch.

Refer to Debian Policy Manual section 4.14 (Source package handling: debian/README.source) for details.

Severity: normal, Certainty: certain
