  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].'';
