+%description
+The mime-types library provides a library and registry for information about
+MIME content type definitions. It can be used to determine defined filename
+extensions for MIME types, or to use filename extensions to look up the likely
+MIME type definitions.
+Version 3.0 is a major release that requires Ruby 2.0 compatibility and
+removes
+deprecated functions. The columnar registry format introduced in 2.6 has been
+made the primary format; the registry data has been extracted from this
+library
+and put into {mime-types-data}[https://github.com/mime-types/mime-types-data].
+Additionally, mime-types is now licensed exclusively under the MIT licence and
+there is a code of conduct in effect. There are a number of other smaller
+changes described in the History file.
