`patch-system-but-no-source-readme`

This package build-depends on a patch system such as 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.
