All reports of quilt-series-but-no-build-dep for the archive. The extended description of this tag is:
The package contains a debian/patches/series file usually used by quilt to apply patches at build time, but quilt is not listed in the build dependencies.
You should either remove the series file if it's effectively not useful or add quilt to the build-dependencies if quilt is used during the build process.
If you don't need quilt during build but only during maintenance work, then you can override this warning.
Severity: normal, Certainty: possible
