# maintainers is the number of maintainers with Lintian errors or warnings.
#
# %tag_statistics holds a hash of tag-specific statistics. Each tag name is a
# key, and its value is a hash with the following keys: count and overrides
# (number of times the tag has been detected and overridden, respectively), and
# packages (number of packages with at least one such tag).

# with each hash having keys code, package, type, tag, severity, certainty,
# extra, and xref. xref gets the partial URL of the maintainer page for that
# source package.
