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.

MIME content types are used in MIME-compliant communications, as in e-mail or
HTTP traffic, to indicate the type of content which is transmitted. The
mime-types library provides the ability for detailed information about MIME
entities (provided as an enumerable collection of MIME::Type objects) to be
determined and used programmatically. There are many types defined by RFCs and
vendors, so the list is long but by definition incomplete; don't hesitate to
add additional type definitions (see Contributing.rdoc). The primary sources
for MIME type definitions found in mime-types is the
{IANA Media Types registry}[https://www.iana.org/assignments/media-types/media-types.xhtml],
RFCs, and W3C recommendations. It conforms to RFCs 2045 and 2231.

This is release 2.5 with a couple of bug fixes, updating to the latest IANA
type registry, and adding a user-contributed type. mime-types 2.x supports Ruby
1.9.2 or later.
