This library allows for the identification of a file's likely MIME content
type. This is release 1.23 that adds the ability to enumerate over the
collection of MIME types and updates the sources of a few MIME types. The
identification of MIME content type is based on a file's filename extensions.

MIME types are used in MIME-compliant communications, as in e-mail or HTTP
traffic, to indicate the type of content which is transmitted. MIME::Types
provides the ability for detailed information about MIME entities (provided as
a set 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 not
complete; don't hesitate to ask to add additional information. This library
follows the IANA collection of MIME types (see below for reference).

MIME::Types for Ruby was originally based on and synchronized with MIME::Types
for Perl by Mark Overmeer, copyright 2001 - 2009. As of version 1.15, the data
format for the MIME::Type list has changed and the synchronization will no
longer happen.

MIME::Types is built to conform to the MIME types of RFCs 2045 and 2231. It
follows the official {IANA registry}[http://www.iana.org/assignments/media-types/]
({ftp}[ftp://ftp.iana.org/assignments/media-types]) with some unofficial types
added from the the {LTSW collection}[http://www.ltsw.se/knbase/internet/mime.htp].
