NAME
       MIME::Type - Definition of one MIME type
SYNOPSIS
        use MIME::Types;
        my $mimetypes = MIME::Types->new;
        my MIME::Type $plaintext = $mimetypes->type('text/plain');
        print $plaintext->mediaType;   # text
        print $plaintext->subType;     # plain
        my @ext = $plaintext->extensions;
        print "@ext"                   # txt asc c cc h hh cpp
        print $plaintext->encoding     # 8bit
        if($plaintext->isBinary)       # false
        if($plaintext->isAscii)        # true
        if($plaintext->equals('text/plain') {...}
        if($plaintext eq 'text/plain') # same
        print MIME::Type->simplified('x-appl/x-zip') #  'appl/zip'
DESCRIPTION
       MIME types are used in MIME entities, for instance as part of e-mail
       and HTTP traffic.  Sometimes real knowledge about a mime-type is need.
       Objects of "MIME::Type" store the information on one such type.
       This module is built to conform to the MIME types of RFC's 2045 and
       2231.  It follows the official IANA registry at
       http://www.iana.org/assignments/media-types/ and the collection kept at
       http://www.ltsw.se/knbase/internet/mime.htp
OVERLOADED
       overload: string comparison()
           When a MIME::Type object is compared to either a string or another
           MIME::TYpe, the equals() method is called.  Comparison is smart,
           which means that it extends common string comparison with some
           features which are defined in the related RFCs.
       overload: stringification()
           The stringification (use of the object in a place where a string is
           required) will result in the type name, the same as type() returns.
           example: use of stringification
            my $mime = MIME::Type->new('text/html');
            print "$mime\n";   # explicit stringification
            print $mime;       # implicit stringification
METHODS
   Initiation
       MIME::Type->new(OPTIONS)
           Create (instantiate) a new MIME::Type object which manages one mime
           type.
            -Option    --Default
             encoding    <depends on type>
             extensions  []
             simplified  <derived from type>
             system      undef
             type        <required>
           encoding => '7bit'|'8bit'|'base64'|'quoted-printable'
             How must this data be encoded to be transported safely.  The
             default depends on the type: mimes with as main type "text/" will
             default to "quoted-printable" and all other to "base64".
           extensions => REF-ARRAY
             An array of extensions which are using this mime.
           simplified => STRING
             The mime types main- and sub-label can both start with "x-", to
             indicate that is a non-registered name.  Of course, after
             registration this flag can disappear which adds to the confusion.
             The simplified string has the "x-" thingies removed and are
             translated to lower-case.
           system => REGEX
             Regular expression which defines for which systems this rule is
             valid.  The REGEX is matched on $^O.
           type => STRING
             The type which is defined here.  It consists of a type and a sub-
             type, both case-insensitive.  This module will return lower-case,
             but accept upper-case.
   Attributes
       $obj->encoding()
           Returns the type of encoding which is required to transport data of
           this type safely.
       $obj->extensions()
           Returns a list of extensions which are known to be used for this
           mime type.
       $obj->simplified([STRING])
       MIME::Type->simplified([STRING])
           Returns the simplified mime type for this object or the specified
           STRING.  Mime type names can get officially registered.  Until
           then, they have to carry an "x-" preamble to indicate that.  Of
           course, after recognition, the "x-" can disappear.  In many cases,
           we prefer the simplified version of the type.
           example: results of simplified()
            my $mime = MIME::Type->new(type => 'x-appl/x-zip');
            print $mime->simplified;                     # 'appl/zip'
            print $mime->simplified('text/plain');       # 'text/plain'
            print MIME::Type->simplified('x-xyz/x-abc'); # 'xyz/abc'
       $obj->system()
           Returns the regular expression which can be used to determine
           whether this type is active on the system where you are working on.
       $obj->type()
           Returns the long type of this object, for instance 'text/plain'
   Knowledge
       $obj->equals(STRING|MIME)
           Compare this mime-type object with a STRING or other object.  In
           case of a STRING, simplification will take place.
       $obj->isAscii()
           Returns false when the encoding is base64, and true otherwise.  All
           encodings except base64 are text encodings.
       $obj->isBinary()
           Returns true when the encoding is base64.
       $obj->isRegistered()
           Mime-types which are not registered by IANA nor defined in RFCs
           shall start with an "x-".  This counts for as well the media-type
           as the sub-type.  In case either one of the types starts with "x-"
           this method will return false.
       $obj->isSignature()
           Returns true when the type is in the list of known signatures.
       $obj->mediaType()
           The media type of the simplified mime.  For 'text/plain' it will
           return 'text'.
           For historical reasons, the 'mainType' method still can be used to
           retreive the same value.  However, that method is deprecated.
       $obj->subType()
           The sub type of the simplified mime.  For 'text/plain' it will
           return 'plain'.
DIAGNOSTICS
       Error: Type parameter is obligatory.
           When a MIME::Type object is created, the type itself must be
           specified with the "type" option flag.
