  +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.
