This package declares source format 3.0 (quilt), but the Debian
.debian.tar.gz file contains a debian-changes-VERSION patch, which represents
direct changes to files outside of the
debian directory. This often
indicates accidental changes that weren't meant to be in the package or changes
that were supposed to be separated out into a patch.
If this is intentional, you may wish to consider adding
debian/source/options, and/or a patch
debian/source/patch-header explaining why this is done.
