+This cop detects instances of rubocop:disable comments that can be
+removed without causing any offenses to be reported. It's implemented
+as a cop in that it inherits from the Cop base class and calls
+add_offense. The unusual part of its implementation is that it doesn't
+have any on_* methods or an investigate method. This means that it
+doesn't take part in the investigation phase when the other cops do
+their work. Instead, it waits until it's called in a later stage of the
+execution. The reason it can't be implemented as a normal cop is that
+it depends on the results of all other cops to do its work.
