# Since this is about checking documentation, a little documentation

# The exceptions structure below is a hash keyed by the module
# name. Any * in a name is treated like a wildcard and will behave
# as expected. Modules are matched by longest string first, so
# A::B::C will match even if there is A::B*

# The value for each is a hash, which contains one or more
# (although currently more than one makes no sense) of the following
# things:-
#   skip   => a true value means this module is not checked
#   ignore => array ref containing list of methods which
#             do not need to be documented.
