Package: quinn-diff
Version: 0.67
Severity: normal
Tags: patch
quinn-diff should support architecture wildcards just as support for them have
been implemented in dpkg and sbuild.
Here's a patch that will allow quinn-diff to support a Packages-arch-specific
that has entries that include architecture wildcards.
