169This file previously contained text expressing a belief that most of
170the files covered by the above exception were sufficiently trivial not
171to be subject to copyright, resulting in confusion over whether it
172negated the permissions granted in the license. In the spirit of
173permissive licensing, and of not having licensing issues being an
174obstacle to adoption, that text has been removed.
