N:
N:    Lintian discovered an unused override entry in its database. Most likely
N:    it was used for a false-positive that has been fixed. However, some tags
N:    are only triggered in packages built on certain architectures. In this
N:    case, the override may need an architecture qualifier.
N:
N:    Alternatively, the additional information provided by Lintian in the
N:    tag's output may changed since the override was last modified.
N:
N:    If the override is unused, please remove it from the overrides file.

N:    Refer to Lintian User's Manual section 2.4.3 (Architecture specific
